Sept. 14, 2022 (Menlo Park, Calif.) – A group of leading organizations, including Meta, REsurety, Broad Reach Power and others, has announced the formation of the Energy Storage Solutions Consortium, a consortium to assess and maximize the greenhouse gas (GHG) reduction potential of electricity storage technologies. The group’s goal is to create an open-source, third-party-verified methodology to quantify the GHG benefits of certain grid-connected energy storage projects, and to ultimately help add a tool for organizations to create credible progress toward their net zero emissions goals.

Once approved by the third-party Verra through the Verified Carbon Standard Program, the standard would be the first verified methodology to quantify the emissions benefits of large-scale energy storage facilities, and would provide valuable guidance such as when to deploy stored energy to deliver maximum emissions reduction benefits. 

“At Meta, we are committed to accelerating the transition to the carbon-free grid of the future, and large-scale energy storage is a critical part of that transition. Having achieved 100% renewable energy for our global operations, we are now looking to help move the energy storage industry forward by addressing next-level challenges and opening pathways that will help drive high impact emissions reductions on the grid,” said Peter Freed, director of energy strategy at Meta. “We are excited to launch this consortium in partnership with these industry-leading organizations, who will bring diverse perspectives and experience to the development of a robust, transparent methodology.”

“We need to decarbonize the grid as quickly as possible, and to do that we need to maximize the emissions impacts of all grid-connected technologies – whether generation, load, hybrid or standalone storage,” says Adam Reeve, SVP of software solutions at REsurety. “Enabling this sort of decarbonizing activity is the exact reason why we invested in developing high-resolution Locational Marginal Emissions. Energy storage is a technology that has huge potential, and we’re delighted to partner with industry leaders in this forward-thinking and collaborative effort to develop a global standard for energy storage benefits.”

“Battery storage will play an increasingly important role in delivering reliable and affordable power to homes and businesses as we move toward a 100% renewable energy grid. As the leading utility-scale battery storage platform in the U.S., we’re looking forward to working with other industry leaders to be able to quantify the important GHG reduction benefits of large-scale energy storage facilities and help organizations take climate action,” says Paul Choi, EVP of origination at Broad Reach Power.

In order to calculate the GHG benefits of large-scale energy storage facilities, the consortium will leverage locational marginal emissions. This concept measures the tons of GHG emissions displaced through the charging and discharging of energy storage facilities on the grid at a specific location and point in time.

In addition to steering committee members Meta, REsurety and Broad Reach Power, the consortium includes a number of advisory committee members. These advisory members include leading technology companies, emissions data providers, investors, storage developers and service providers, and non-governmental organizations among others.

Members include:
3Degrees Group, Inc., Akamai Technologies, Clearloop, Equilibrium Energy, Fluence, General Motors, GlidePath Power Solutions, Habitat Energy, Hannon Armstrong, Jupiter Power, Longroad Energy, Marathon Capital, Microsoft, Primergy Solar, Quinbrook Infrastructure Partners, RES Group, Rivian, Rowan Digital Infrastructure, Stem, Tabors Caramanis Rudkevich, TimberRock, UBS Asset Management, and WattTime.

The Energy Storage Solutions Consortium is also partnering with Perspectives Climate Group, the German consultancy dedicated to helping its clients achieve net zero GHG emissions and to developing practical solutions for accounting of emission reductions from innovative climate- friendly technologies.

White Paper: Making It Count

Updating Scope 2 accounting to drive the next phase of decarbonization

Authored by David Luke Oates, Senior Vice President of Power Markets Research, REsurety

Dr. Oates holds a Ph.D. in Engineering and Public Policy from Carnegie Mellon University and a Bachelor’s degree in Engineering Physics from Queen’s University, Canada.

EXCERPT: Corporations are increasingly focused on reducing their carbon footprints by decarbonizing the electric grid. While solar and wind energy development have rightly been a mainstay of these efforts, there is growing consensus that producing more clean energy alone isn’t enough. To maximize grid decarbonization, clean generation needs to occur at times and locations where its output displaces the highest-emitting resources. Consumption timing and location should be adjusted to minimize its carbon emissions via siting decisions, demand flexibility measures, and energy efficiency. And energy storage is needed to manage grid congestion and mismatches between clean supply and demand.

Effective carbon accounting frameworks can help coordinate these complex mitigation strategies by allocating emissions among the entities responsible for producing them. These accounting frameworks attempt to ensure that activities with more impact on actual emissions have more impact on carbon accounts. Given the large and increasing interest of investors, customers, regulators, and governments in corporate decarbonization initiatives, effective carbon accounting frameworks can encourage corporations to maximize their actual carbon reductions.

Options for EIA to Publish CO2 Emissions Rates for Electricity, as published by Resources for the Future

The path toward decarbonization in the United States entails not only a mix of federal, state, and local government policies promoting clean energy, but also voluntary efforts by the private actors to reduce their CO2 emissions.

Authored by Karen Palmer, Brian Prest, Stuart Iler, and Seth Villanueva

Resources for the Future reviews use cases for emissions rate data and different options available to the Energy Information Agency for publishing data on both average and marginal emissions rates. Existing methods and data sources, such as REsurety’s Locational Marginal Emissions data, are discussed and evaluated. Read the executive summary excerpt below.


Decarbonization efforts in the US consist of a mix of government policies to promote clean sources of energy and improve energy efficiency and voluntary actions by private actors to reduce their CO2 emissions. Understanding both the likely and actual benefits of both policies and private actions requires information about the carbon intensity of different sources of energy including electricity. Demand for data on the CO2 intensity of US electricity production and consumption is growing as governments and private companies seek to understand the emissions effects of both their electricity consumption and their clean energy investment choices. Emissions rate information is also important for Scope 2 emissions accounting under the GHG Protocol Corporate Standard1 that provides a way of tracking progress toward clean energy targets that many companies have declared.

The desire for transparent and consistent data on electricity emissions rates led the US Congress, in the Infrastructure Investment and Jobs Act (IIJA), to call for the US Energy Information Administration (EIA) to publish spatially and temporally granular electricity emissions rate data, beginning in late 2022. Specifically, the IIJA calls on EIA to report on hourly operating data, including “where available, the estimated marginal greenhouse gas emissions per megawatt hour of electricity generated” within each balancing authority and by pricing node. The law also calls on EIA to harmonize its electric system operating data with GHG and other relevant data collected by EPA or other federal agencies, as well as data collected by state or renewable energy credit registries. The resulting integrated data set should include net generation data and “where available, the average and marginal greenhouse gas emissions by megawatt hour of electricity generated within the boundaries of each balancing authority,” to be offered on a real-time basis through a publicly accessible application programming interface (API).

The Enhancement and Standardization of Climate-Related Disclosures for Investors

Wind Energy

REsurety’s letter to the Securities and Exchange Commission Re: File No. S7-10-22, dated June 17, 2022


On behalf of REsurety, Inc., a leading analytics provider in the clean energy economy, we are writing in support of File No. S7-10-22: The Enhancement and Standardization of Climate-Related Disclosures for Investors. We also suggest two specific language refinements to improve the accuracy and transparency of Scope 2 emissions disclosures.

Anticipated Value of the Proposed Rule

For the last 10 years, REsurety has helped our clients understand the risks and value of buying and selling electricity from clean energy projects. Many of our clients develop renewable energy projects, have made voluntary public GHG reduction commitments, or own assets exposed to climate-related risk. The SEC’s proposal to require detailed climate-related disclosures has the potential to benefit our customers, as well as the public and the planet. By requiring disclosures from a large category of companies, the proposal protects investors from unintentional exposure to climate-related risk. By standardizing disclosure requirements and requiring attestation, the proposal can also help substantiate GHG reduction claims. In short, the proposed rule has the potential to increase efficiencies in capital markets, boost investor confidence and encourage companies to take effective climate action at scale.

Challenges with the GHG Protocol

While we strongly applaud the SEC’s aims, we are concerned about the pivotal role the GHG Protocol plays in the SEC’s proposal, particularly with respect to Scope 2 emissions disclosures. The proposed GHG emissions disclosure requirements are based “primarily on the GHG Protocol’s concept of scopes and related methodology”.1 The proposed rule cites the GHG Protocol Scope 2 Guidance as a methodological source for determining Scope 2 inventories.2

The GHG Protocol Scope 2 Guidance allows reporting entities to select from an extensive hierarchy of emissions factor data to calculate their footprints. Application of some of these emissions factors would result in footprints that differ materially from actual GHG emissions. For example, the current Scope 2 Guidance lists Renewable Energy Credits (RECs) as the highest-quality “emissions factor” data type but takes no position on where or when RECs are produced relative to their consumption. An entity consuming power in a coal-heavy grid could eliminate its Market-Based Scope 2 footprint by purchasing sufficient RECs from a very clean grid, even when such a purchase would have a negligible effect on actual GHG emissions.

By relying on average emissions factors, current Scope 2 guidance also risks sending signals to registrants that are at odds with the goal of reducing carbon emissions. Consider a registrant purchasing solar energy that mostly displaces coal generation, in a grid that also includes considerable baseload nuclear. Since the average emissions rate of this grid is much lower than the emissions rate of the displaced coal, the reduction in the registrant’s carbon footprint would not reflect the solar energy’s full carbon impact. As a result, the registrant may hesitate to contract for the solar energy in the first place, knowing that its actual carbon benefits could not be reported.

[2] Proposed Rule, §II.G.2.c (p. 195). The proposed rule also cites the EPA’s guidance on Indirect Emissions from Purchased Electricity, which is highly similar to the GHG Protocol Scope 2 guidance. See §II.G.1.b. (p. 160)


Carbon Accounting with the Greenhouse Gas Protocols: Successes and Emerging Challenges

David Luke Oates
David Luke Oates is a carbon accounting subject matter expert.
David Luke Oates

By David Luke Oates, SVP of Power Markets Research, REsurety

The Greenhouse Gas Protocol is a foundational component of modern climate standards. It is incorporated into the Task Force on Climate-Related Financial Disclosures’ (TCFD) guidelines for voluntary climate disclosures1, as well as the Science-Based Targets Initiative’s (SBTi’s) recommendations for aligning corporate targets with climate goals.2 It has also largely been paralleled in the U.S. Security and Exchange Commission’s recent proposed rule on climate disclosures.3

The GHG Protocol has achieved considerable success in providing a common framework for voluntary disclosures. But it is now a fairly outdated standard, and its flaws are becoming more impactful and problematic. The GHG Protocol Corporate Standard was originally released in the early 2000s, with updated Scope 2 guidance released in 2015. The nearly seven years since that release have featured dramatic increases in corporate clean energy purchases and interest in accurate corporate climate disclosures.4 There is now growing interest in updating the GHG Protocol and addressing some of its shortcomings.

At REsurety, we spend much of our time helping buyers and sellers of clean electricity to manage their financial risks and achieve their decarbonization goals. We are particularly interested in ensuring that Scope 2 accounting is as effective as possible. Today, the GHG Protocol Scope 2 Guidance has two major flaws: 1) it does not ensure that all actual carbon emissions are accounted for across entities and 2) it often doesn’t create the right incentives for entities interested in decarbonization. 

On the first item, the GHG Protocol’s Market-Based method for Scope 2 accounting allows reporting entities to apply REC purchases to cover their consumption at an emissions rate of 0 tons/MWh. It also allows entities to account for their grid consumption by applying a simple-average emissions rate. This average emissions rate reflects the same clean energy claimed through REC retirements, effectively double-counting the impact of clean energy and contributing to under-reporting of emissions.5 While this double-counting may have been of little concern a decade ago, the volume of today’s clean energy purchases make it a more serious problem.

On the second item, by relying on average emissions rates with low temporal and spatial granularity, current Scope 2 guidance risks send the wrong signals to entities interested in decarbonization. Consider an entity purchasing solar energy that mostly displaces coal generation, in a grid that also includes considerable baseload nuclear. Since the average emissions rate of this grid is much lower than the emissions rate of the displaced coal, the reduction in the entity’s carbon footprint would not reflect the solar energy’s full carbon impact. In general, the activities achieving the greatest amount of decarbonization are not fully rewarded under the current GHG Protocol, creating a misalignment of incentives. We think there is an opportunity to fix both of these problems.

Governments and corporate entities have recently made ambitious climate mitigation commitments. Truly delivering on these commitments will require a modernized set of carbon accounting rules to align incentives and avoid double-counting. We believe that a revised Scope 2 carbon accounting framework based on granular marginal emissions data can help address some of the shortcomings we mentioned above. We look forward to sharing more details on potential solutions to these challenges in the months to come.

In the interim, we love talking with anyone who shares our goals of more accurate carbon impact measurement and the tools to maximize that impact – so please contact us at [email protected] if you have any questions or want to connect and discuss.

[5] While this double-counting could theoretically be corrected by applying the residual mix emissions rate to all parties’ grid consumption, this approach is not feasible in many jurisdictions. Calculating the residual mix emissions rate depends on visibility into all private contracts for RECs between counterparties, something that individual reporting entities aren’t able to provide. In jurisdictions (such as the U.S.) where residual mix emissions rates are not available, current GHG Protocol guidance is to apply the average emissions rate to grid purchases.

REsurety’s REmap Q1 State of the Renewables Market report presents generation-weighted value, shape value, and capacity factor for major U.S. hubs

BOSTON, MAY 10, 2022 – The U.S. power grid saw record lows in the first quarter of 2022, REsurety’s REmap Q1 2022 State of the Renewables Market Report finds, with prolonged negative pricing in Texas expected to ease this summer.

Unlike the soaring prices of last year during the Texas energy crisis of February 2021, this year the ERCOT power grid saw record lows in Q1. It was another turn in a developing plotline REsurety commented on last quarter. 

One example: In February 2021, ERCOT West Hub (among others) settled at the market price cap of $9,000/MWh for three days; in February 2022 ERCOT West Hub saw a two day period where prices never rose above $0/MWh. Mild demand coupled with sustained periods of high wind and solar generation created the conditions for this negative pricing event, though these conditions weren’t isolated to only those few days. In fact, by the end of the quarter, West Hub more than doubled the number of negative-priced hours than were seen in Q1 the year prior.

REsurety creates the REmap-powered State of the Renewables Market report every quarter to provide readers with data-driven insight into the value and latest emerging trends of renewables in U.S. markets. The team uses its knowledge in power markets, atmospheric science, and renewable offtake to analyze thousands of locations, and summarize a few key findings, using the data that is available via its interactive software tool, REmap.

Key components in the report to be used to analyze trends in a given ISO, sub-regions of an ISO, or hub, are:

  • The generation weighted value, or the realized value of the wind and solar projects 
  • The shape value, or the relationship between the generation value and the simple-average market price
  • The net capacity factor for operating wind and solar projects 
Blair Allen, Director, Software Customer Success, REsurety
Blair Allen

“Using the modeled energy in REmap, which tells us how projects could have performed based on underlying wind/solar resource availability, last quarter West Texas solar projects saw anywhere from 20 to 30% of their potential hourly production for a given month happen in negatively priced hours. However, in reality, these projects weren’t operating at their potential capacity in these intervals, and either shut down or significantly ramped down production,” reports Blair Allen, Director, Software Customer Success, REsurety. 

Over the next quarter as the weather starts to transition to summer conditions negative pricing is expected to decline. With an increase and shift in demand, Q2 will likely be a transitional period, with the frequency of negative pricing hours remaining high to start before subsiding more materially by the end of the summer in mid Q3. 

The power of REmap lies in the historical and predictive modeling for renewable energy projects across the United States, as well as the ability to analyze hypothetical installations. Learn more by reading the Q1 report

Friends don’t let friends use 8760s

says Jennifer Newman, VP of Atmospheric Science Research, REsurety

As featured in POWER Magazine

Any company embarking on a new project must do its research to ensure that it calculates the proceeds based on the right financial information. With so much data now readily available, it’s more important than ever to use the right data, and make accurate calculations. 

REsurety's Jennifer Newman, VP of atmospheric science research, talks about 8760s.

Amid the boom in demand for renewable power plants, that is not always happening when backers go to measure the value of the energy they will generate. Here’s why, according to Jennifer Newman, Vice President of Atmospheric Science Research at REsurety, the Boston-based renewable industry data and analytics company. 

Q: What is an 8760 and how is it used in the renewable energy industry?

A:  An 8760 (sometimes referred to as a typical meteorological year or TMY) consists of hourly generation values for a wind or solar project for all 8,760 hours of a typical year. Importantly, 8760s are almost always used to represent average generation for a renewable energy project in a given hour. 

Q:  And what’s the problem? Why shouldn’t 8760s be used to estimate the value of power generation being produced by renewable energy projects? 

A:  An 8760 isn’t bad on its own – it’s a perfectly acceptable way of representing average generation. The issue is when a generation 8760 is paired with hourly power prices to produce either a revenue backcast (an estimate of the revenue a project would have made given historical prices) or a revenue forecast (an estimate of how much revenue a project could earn in the future). 

The problem with a backcast is that hourly renewable generation influences power prices during each hour. And that’s because wind and solar tend to be very inexpensive sources of electricity. So an hour where there’s a lot of wind or solar on the grid will tend to be associated with lower power prices, particularly in markets with high renewable penetration. When you use an 8760 instead of actual generation values during each timestamp, you aren’t able to capture that impact of hourly generation on hourly power prices.

And when analysts are using a model to predict future power prices, it’s a mistake to assume that conditions in the future will be similar to  an “average weather year”. Abnormal weather conditions can cause drastic price changes, as we all saw in Texas during February 2021.

Q: So what should be used to accurately calculate the value of renewable power generation?

A: There’s an abundance of rich datasets we can use to inform our decisions on whole new levels. For a backcast analysis, we should be using concurrent generation and price time series data to make these calculations and avoid errors (i.e. the generation volume that is used for 7:00 am on January 13th, 2019 should reflect the same weather conditions that generated the price that was observed in that same hour). In a forward-looking scenario, you should use a variety of different potential weather conditions beyond just an average year. Would you want to use a typical Texas February to project possible gains and losses, now that you know that Texas in February of 2021 is possible?  

Q: Where does a company turn then, to ensure it’s using the right information?

A:  At REsurety we offer the REmap tool, which models hourly generation for every wind and solar project in the United States, and will soon look forward at hypothetical situations to allow for future planning. REmap also offers data for synthetic situations – what-if planning for potential future sites – including historical modeled generation, observed power prices, and the combination of generation and power prices to estimate revenue. 

Getting beyond 8760s can not only steer a company to site a new renewable project in one location versus another, it can also provide guidance on the financial risk associated with a range of potential weather conditions.

High-resolution carbon emissions data now available for PJM Mid-Atlantic power grid

Adam Reeve

New data empowers wind, solar and energy storage projects and load centers to accurately calculate their carbon impact

BOSTON, March 17, 2022 – REsurety announced today the expansion of its breakthrough Locational Marginal Emissions (LME) carbon data tool to the PJM power grid in the U.S. Mid-Atlantic region. Previously available only in Texas’s ERCOT grid, the expansion of the data set into PJM results in a dramatic increase in the number of locations for which the high-resolution emissions data is available, with now nearly 15,000 distinct locations served. It’s also the first time that REsurety will be releasing data at the five-minute level, which is particularly valuable for understanding the impact of storage on the PJM grid. The company intends to scale LMEs to the rest of the United States and internationally.

Adam Reeve, senior vice president of software, REsurety

The Locational Marginal Emissions data set measures marginal carbon emissions rates at each node on the grid, enabling insight to the impact of each specific clean energy project site or load location. This capability allows project developers, investors, and corporations to accurately understand the carbon impact of their activities.

“This data is critical for efficiently decarbonizing the grid, as we can now see the impact of specific projects and activities on system-wide emissions,” said Adam Reeve, Senior Vice President of Software, REsurety. “By understanding the carbon emissions impact of specific technologies at specific locations, we can ensure that clean energy strategies are more precisely targeted to where they can have the biggest impact.”

Reeve continued, “We are especially excited about what this means for the value proposition of energy storage. While many people intuitively understand that storage is a necessary technology for decarbonization, historically the industry has lacked the tools to measure its impact accurately.

“But with this level of nodal granularity, we can measure the impact of specific storage projects on the grid during both charging and discharging. We can see, for example, how some projects charge when the marginal generator is clean, and then discharge when the marginal generator is dirty, avoiding a significant amount of carbon emissions in the process.”

“We can also see how other storage projects, unfortunately, can actually increase system emissions. It’s not a one-size-fits-all technology. Where you site energy storage and how you schedule its dispatch can mean the difference between significant increases or decreases in carbon emissions. This data empowers investors and storage operators to measure and maximize their carbon reduction impact.”

Recognizing the value of marginal carbon emissions data, PJM started publishing marginal emissions rates at load node locations starting in January, 2021. REsurety’s data set builds on that initial step in a number ways, including by extending the data set to cover generator nodes and correcting anomalous data points (or outliers) with values consistent with the actual topology of the transmission grid. REsurety also leverages its own models to extend the nodal data back several years, enabling analysis of longer-term market trends.

The resulting LME data set takes into account real-time grid congestion, actual emissions rates by each generator unit, and the physical power flows throughout the system. The data set is available via an API and being integrated into REsurety’s other software tools.

“LMEs can be used to measure the carbon impact of any sustainability strategy – whether it is focusing on local procurement, 24/7 matching, or maximizing your carbon emissions impact,” said Reeve. “We’re excited for this high-resolution emissions data to enable better measurement and decision-making across the board.”

REsurety’s Locational Marginal Emissions data is currently available in ERCOT and PJM, and will be available for other markets later this year. To learn how your company can better measure and maximize the carbon impact of your clean energy initiatives, contact us at [email protected].

MEDIA ADVISORY: Solar + Wind Finance & Investment Summit

A year since the February 2021 power crisis in Texas, how have renewable energy hedge markets changed?

ERCOT lessons include new ways to incentivize generators to stay online when their electrons are most needed

BOSTON, Feb. 28, 2022 – Financial hedging tools used to manage clean energy generation and procurement risk have seen major changes in the past year, after the 2021 deep freeze in Texas upended power markets and resulted in outsized gains and losses for many in the industry. 

In an effort to limit their risk during such extreme weather events, many clean energy power producers have returned their focus to traditional as-generated power purchase agreements where operational shutdowns during price spikes are typically permitted with limited or no penalties. 

Lee Taylor, co-founder and CEO of REsurety will be featured on a panel at the Solar + Wind Finance & Investment Summit.

The result could be a reduction of demand for clean energy from financially-motivated buyers, as well as a reduction in grid resiliency, warns Lee Taylor, CEO of REsurety, who will speak at the Solar + Wind Finance & Investment Summit next Monday in Scottsdale, Arizona. “If project shutdowns during periods of high demand have a limited impact on a project owner, there will be no incentive for resiliency, ” he says. 

Taylor is not alone in that view. Jay Bartlett of Resources for the Future wrote last March in the aftermath of the Texas deep freeze, blackouts, and $9,000-a-megawatt-hour power rates:

“The Texas power crisis has shown how different sales and hedge structures create very different levels of incentives for a wind project to generate during times of scarcity. While most attention focuses now on projects that either sustained great losses or earned windfall profits, more alarming over the long term are projects that were financially unaffected by the crisis. Those generators may have had little motivation to produce power during a time of great need. Appropriate incentives may not guarantee power supply—clearly, they did not last month—but aligning incentives between wind projects and system needs will better promote beneficial investments and operations. As wind and solar comprise an increasing percentage of power generation, well-designed hedge structures could prove instrumental to power system reliability.”

One solution is a hybrid between historically metered generation and proxy generation-based settlement methods. Future offtake contracts, such as vPPAs, can settle on metered generation but proxy generation (which represents what a project should have produced assuming normal operations and project availability) is utilized to calculate the financial impact of project operations. If that impact exceeds a materiality threshold, damages are owed by the project up to a cap. The materiality threshold and cap on damages would be agreed to by the project and the offtaker.

 “The goal is to preserve the best of both worlds,” says Taylor. “Projects understandably don’t want to bother with calculating proxy generation when the project is operating normally, and after winter storm Uri, projects are no longer comfortable with uncapped financial exposure to operations. This contracting method addresses both of those concerns, while preserving the offtaker’s interest in quantifying the financial cost of a project’s operational performance, and having some recourse when that cost is material.”

Taylor will elaborate during the panel, “Focus on Potential Gamechangers 1: Implementing Changes to the Hedge Market,” at 2:45 pm Mountain Time on Monday, March 7. Moderated by James T. Tynion III, Partner, Morgan, Lewis & Bockius, the panel will also feature Andrew Ehrlickman, Vice President, Brookfield Asset Management. The session promises to address how the financial fallouts from extreme weather events “have completely restructured the entire hedge industry by exposing huge risks lurking in the periphery.” 

The speakers will provide a deep dive into the long-term effects of recent freezes, heat waves, and storms; the changing risk appetites of parties and updated valuations in hedge calculations; and new hedge structures that are emerging. Also on the agenda: How to value weatherization, impacts on tax equity, and the appeal of merchant projects.

REsurety and WattTime partner to increase accessibility to high-quality marginal carbon emissions data

Enhanced power grid insights will enable more effective investments in renewables, storage, and load siting.

Boston, Mass. and Oakland, Calif. –  Nov. 2, 2021 – Today clean energy analytics firm REsurety and environmental tech nonprofit WattTime announced a partnership to increase access to more comprehensive and granular carbon emissions data across U.S. and international markets. Through this partnership, they will leverage their respective strengths in measuring marginal carbon emissions to provide previously unavailable depth and breadth of visibility into the carbon impact of their energy-related procurement options and understand which choices offer the greatest benefit to the environment. 

WattTime and REsurety announced partnership focused on enhancing marginal emissions data

REsurety first unveiled its Locational Marginal Emissions (LME) data product in July 2021 with the support of major developers, investors, and corporates. LME empowers customers to measure and maximize how much carbon they cut through clean energy purchases. REsurety currently offers nodal LME data for the ERCOT (Texas) market. Through this new integration of WattTime’s regional emissions dataset, REsurety will also be able to provide regional marginal emissions rates across the entire continental United States as well as international power grids including Europe and Australia. 

“LME enables companies to measure the impact of their existing clean energy purchases with unrivaled accuracy and confidence, and empowers them to maximize the carbon impact of their future investments,: said Lee Taylor, founder and CEO of REsurety. “We are thrilled to have found a like-minded partners in WattTime as we work together to maximize our collective decarbonization impact.”

WattTime invented Automated Emissions Reductions (AER) software, which enables the shifting of flexible electricity loads to periods of cleaner energy and away from moments of dirtier energy, based on the time-specific marginal emissions rates in different grid balancing areas. In recent years, WattTime has also popularized “emissionality”, the practice of using the location-specific avoided emissions benefits of different renewable energy projects in the selection process. With WattTime’s help, organizations including Boston University, solar developed Clearloop, steel producer Nucor, and tech giant Salesforce have all incorporated emissionality into their renewable energy strategies. 

“With the growing urgency of the climate crisis and organizations’ desire to maximize the positive impact of their sustainability strategies and investments, REsurety and their LME platform offer a powerful tool to evaluate potential projects,” said Henry Richardson, senior analyst at WattTime. “We’re proud to support REsurety and enhance the emissions intelligence they are are able to provide.”

LMEs bring a new level of precision and accuracy to measuring the carbon abated or created at any given moment and at any given location on the grid. By calculating the carbon emissions at each node on the grid with hourly granularity, REsurety’s LME product offers, for the first time, visibility into the project-specific carbon impact of each clean energy purchase or investment. By integrating WattTime’s emissions data into its platform, REsurety will be able to provide its clients with regional marginal emissions data in areas where the nodal LME data is not yet available, thereby greatly expanding the geographic coverage of the platform.

REsurety launches Locational Marginal Emissions data product to empower customers to measure and maximize how much carbon they cut through clean energy purchases

Microsoft and other sustainability leaders adopt new tool to evaluate project-specific carbon impact of solar, wind and energy storage – a first for the industry.

BOSTON, July 14, 2021 – REsurety announced today a new data tool, called Locational Marginal Emissions, created with Microsoft and built on the Microsoft Azure cloud platform, to help customers maximize decarbonization investments. Top clean energy buyers, investors, and advisors including Microsoft, Hannon Armstrong, Marathon Capital, Akamai Technologies, Quinbrook Infrastructure Partners, Broad Reach Power, and The Brattle Group will use the new data product from REsurety to measure and maximize the decarbonization impact of each dollar they spend on solar, wind, and energy storage.

Buying clean energy is a means to an end: decarbonization. While many corporations have committed to achieve carbon neutrality or “net-zero” by a certain date, the methods for measuring and maximizing progress have been limited by a lack of data. To date, carbon measurement tools have relied on regional averages, which can materially over- or under-estimate the carbon impact of a specific clean energy project.

The new Locational Marginal Emissions data tool from REsurety addresses this problem.

REsurety’s patent-pending Locational Marginal Emissions technology calculates the carbon emissions at each node on an electric grid with hourly granularity. This helps decision-makers understand how much each specific clean energy procurement, load-siting, or energy storage decision contributes to their decarbonization goals.

Corporations can more precisely and strategically address their net-zero and carbon-free goals by using Locational Marginal Emissions to more accurately measure how much carbon is being avoided by their specific clean energy projects, as well as to better measure how much carbon is emitted as result of their electrical load.

“Locational Marginal Emissions solve the need for transparent and accurate carbon impact data,” said Lee Taylor, CEO of REsurety. “It’s what corporate ESG leaders want to know: how many tons of carbon emissions are actually avoided by the clean energy they’re buying.”

“We can play a key role in fully decarbonizing the grid,” said Brian Janous, GM of Energy and Renewables, Microsoft. “To do it the fastest and the most cost-effectively, we need to be able to understand the carbon impact of each MWh coming from a specific wind, solar, or storage plant. We want to make sure that the clean energy we’re helping to bring onto the grid has the maximum environmental benefit. REsurety’s Locational Marginal Emissions data gives us the transparency we need to make climate-wise investments.”

Sustainability leaders who will use the new data tool range from tech companies to investment banks and impact investors.

Climate investment firm Hannon Armstrong will use Locational Marginal Emissions to further enhance its sustainability investment screen for clean energy assets. “Understanding the carbon impact for all current and future portfolio projects is central to our purpose as a climate positive investor. LMEs offer precision that previously did not exist in the marketplace, and we are pleased to incorporate this innovative and complementary data set alongside our CarbonCount® methodology,” said Rich Santoroski, Chief Analytics Officer.

Marathon Capital, an industry-leading investment bank and advisor, plans to use Locational Marginal Emissions to support their clients. “We are eager to apply this data-driven approach to empower our clients to invest in projects with the largest carbon-reducing impact,” said Joan Hutchinson, Managing Director of the Offtake Advisory group.

David Scaysbrook, Managing Partner of Quinbrook, said, “REsurety is tackling a fundamental data gap we have all been grappling with. Reducing carbon emissions by deploying impactful renewables at scale lies at the core of our work at Quinbrook. Using LMEs will help us be even more discriminating in the investments we make, and it will assist us, our investors, and our offtake customers to create accurate carbon assessments that both track our ‘value add’ and meet increasing reporting obligations.”

REsurety VP of Power Market Research Dr. David Luke Oates and Dr. Kathleen Spees of The Brattle Group co-authored a white paper earlier this year that introduced the new Locational Marginal Emissions approach. “Increasingly, electricity systems that are decarbonizing will face grid pockets of clean energy ‘saturation’ where developing more clean energy will offer diminishing decarbonization value. LME data will offer policy makers and consumers the information they need to shift program dollars to where it can make the greatest impact,” said Dr. Spees.

Akamai Technologies, a leading provider of solutions that protect and deliver digital content, plans to use Locational Marginal Emissions to improve measurement of emission reductions derived from renewable energy investments. “In order to achieve our 2030 sustainability goals, which include powering 100% of global operations with renewable energy, we need transparency and accuracy in measuring our emissions,” says Mike Mattera, Director of Corporate Sustainability. “REsurety’s LMEs provide us with an extra level of confidence in our calculations.”

“Broad Reach Power is proud to join this group of industry leaders as an early adopter of the Locational Marginal Emissions tool,” said Paul Choi, EVP of Origination at Broad Reach Power, an owner/operator of utility-scale wind, solar, and energy storage power projects. “With a storage pipeline exceeding 14 GW, granular carbon emissions data will be crucial to ensure we more efficiently reduce carbon emissions while increasing grid reliability.”

REsurety’s Locational Marginal Emissions data is available for projects in ERCOT and will be available for other U.S. markets later this year. To learn how your company can better measure and maximize the carbon impact of your clean energy investments or purchases, contact [email protected]

POWER, FINANCE & RISK: Locational Marginal Emissions

Clean energy strategies can miss true carbon emissions avoided if they’re based on regional and annual averages, Power Finance & Risk reported May 10 in a story by Taryana Odayar.

Increasingly popular “24/7 clean energy” strategies can miss project details if they’re based on regional and annual averages, Power Finance & Risk reported May 10 in a story by Taryana Odayar.

“That strategy ignores the sub-regional transmission congestion that can have a significant impact on carbon intensity,” the magazine quoted  REsurety CEO Lee Taylor saying on Norton Rose Fulbright’s May 4 Currents podcast . Instead, REsurety has a new way to measure carbon called “Locational Marginal Emissions” that looks at exactly where and when energy is added to the grid.

“We have a common enemy which is that not all megawatt-hours are equal, so a megawatt-hour generated from one location can be meaningfully different from another location based off of the electrical grid that that’s operating,” Taylor said on Currents. “As companies are trying to go carbon-neutral, carbon-free, carbon-negative, they need more than annual megawatt-hour accounting to do that effectively.”

Power Finance & Risk linked to REsurety’s white paper with The Brattle Group on LMEs, which compares two solar projects in West Texas. One displaces twice as much carbon because it has access to transmission to displace coal-fired generation, while the other curtails another nearby solar plant. The result helps companies such as Google that are committed to 24/7 strategies find out exactly how much carbon they’re reducing.

REsurety Adds Hourly Price and Generation Granularity to REmap

Texas crisis illustrates how hourly generation during high-priced hours spells the difference between big wins and big losses for clean energy buyers and sellers.

Hourly power price and generation data is now available in REmap, a tool widely used by leaders in the renewable energy industry to identify value, understand risk and optimize offtake and hedging strategies. REmap’s new Hourly Data Explorer allows users to investigate the hourly performance of thousands of operational and synthetic projects.

The Hourly Data Explorer continues REsurety’s commitment to provide unrivaled breadth of market intelligence and depth of project-specific insight, empowering key decision makers.

“The February winter storm across the Southwest provided an extreme example of an already clear trend: fortunes are made and lost by generating during the right hours, not simply by achieving a high annual energy production,” said Lee Taylor, founder and CEO of REsurety. REsurety launched the map-based tool in May 2020 as an SaaS product, to provide the data and analytics required by the complex, data-driven industry that is the modern renewable power market.

Last year, REsurety used REmap to reveal how low energy demand during the coronavirus shutdown — combined with low natural gas prices and high renewable generation in April 2020 — sent the production-weighted wholesale price of wind-generated electricity to all-time lows across the SPP, PJM and MISO power grids. 

This week, in a column for Utility Dive, REsurety digs into what REmap data tells us are the top trends and takeaways in renewable energy markets today. 

The resiliency that the Texas grid so badly needed in February 2021 was foreshadowed by similar — though smaller — power market events in 2020 and 2019. “One thing REmap shows us is what renewable energy projects could have generated during the Texas deep freeze of February 2021, based on the actual wind and solar resource available,” Taylor said. 

REmap Hourly Data Explorer Screenshot
A screenshot from REmap’s Hourly Data Explorer shows a modeled wind project in south Texas during key hours of the February 2021 deep freeze. 

Theoretical project generation data, given site-specific weather conditions and plant characteristics, will be available in REmap in early March.  Hourly metered generation at the project level for ERCOT projects will follow in early May. REmap can help users understand the financial implications of the February 2021 deep freeze on contract settlements, and inform their expectations moving forward.

REmap stands for “Renewable Energy Market Analytics Platform.” To keep it populated with the latest information, REsurety collects, cleans, and analyzes billions of data points from a wide range of sources. Industry leaders use the resulting massive database to inform their decision making on new investments, to benchmark against their peers and competitors, and to inform their offtake strategies – both as buyers and sellers. Current REmap customers include developers, investors, C&I buyers, and advisors. Joan Hutchinson, Managing Director of Marathon Capital and an early REmap client, described REmap as “a sea change in the access to quantity and quality of data.”

An Innovative Offtake Contract Makes Its Solar Sector Debut

First used with wind projects, a pgPPA manages weather-related risk by settling a facility’s energy transfer based on a proxy generation index, rather than on actual metered generation. Operational risk shifts from buyer to seller.

An innovative financing deal is the latest evidence that solar is entering the mainstream among big institutional investors.

Lightsource bp secured what’s known as a proxy generation power purchase agreement (pgPPA or Proxy Gen) with the Capital Solutions unit of Allianz Global Corporate & Specialty (AGCS), in partnership with Nephila Climate.

The pgPPA covers electricity generated by Lightsource bp’s 153 MW Briar Creek solar farm, under construction in Navarro County, Texas.

In simple terms, a pgPPA is a renewable energy contract designed to manage weather-related risk. In practice, it settles energy transfer from a facility based on a proxy generation index, rather than on the metered generation. That means proxy generation is an hourly index that determines the volume of energy that a project would have produced if it had been operated as specified by the developer or owner.

The arrangement hinges on both the owner and the offtaker agreeing on a set of weather metrics to establish the proxy generation component. In the case of Lightsource bp’s Briar Creek facility, REsurety Inc. will serve as the calculation agent over the life of the contract.

The pgPPA reflects the fact that solar “can stand on its own two feet” and not be so tied either to a purchase power agreement or public policy directive, said Lee Taylor, REsurety’s founder and CEO in an interview with PV Magazine USA.

Early adopters

Taylor said that the pgPPA structure emerged a few years ago in the wind energy sector, and variations are common in agribusiness, as well as ski resorts, among other weather risk-related markets. One of the technique’s first uses in renewable energy was with the 178 MW Bloom Wind facility in Kansas, part of the Southwest Power Pool. U.S. Capital Power operates Bloom Wind under a 10-year fixed price contract with Allianz Risk Transfer that covers 100% of the project’s output.

Under the contract, signed in 2016, Capital Power swaps the market revenue from the wind project’s generation for a fixed annual payment over a period of 10 years. The agreement secures long-term predictable revenues and mitigates generation volume uncertainty related to the intermittent nature of the wind resource.

Taylor said that similar structures have been used on wind projects in PJM and ERCOT in the U.S., as well as in Australia. The Briar Creek deal is considered to be the technique’s first use in a U.S. solar project.

“This deal is a great example of the evolution of renewable energy products here in the U.S.,” said Kevin Smith, CEO of Lightsource bp in the Americas. He said that innovative power contract structures such as virtual and pgPPA’s are “valuable tools we can leverage to meet the needs of our corporate partners, manage risk, and continue to finance and build new solar projects.”

Ariane West, Director of Structured Finance, Nephila Climate, said that risk transfer approaches “are essential to support investment and financing of infrastructure on the scale needed to achieve zero carbon targets.”

PPAs and related structures

Purchase power agreements are commonly used structures between a solar facility’s owners and an energy offtaker, often a utility or large manufacturer. In a variation known as a virtual PPA, contract terms focus on the amount of energy the facility delivers to the grid. Typically, the quantity is measured by an electrical meter at the point of interconnection. By settling the energy delivery at the interconnection point on an “as generated” basis, the buyer is exposed to a number of operational risks.

In a pgPPA, the focus is the amount of energy that should have been delivered to the grid had the plant operated according to equipment efficiency factors and operational best practices. The approach shifts operational risk away from the offtaker and onto the seller.

The pgPPA measures the actual wind or solar resource at the facility. It then runs that measurement through an agreed-to formula that estimates how many megawatthours should have been produced given the facility’s size and operations under best practice standards.

In the case of Briar Creek solar, REsurety is providing the hourly solar radiance data, which will be managed using PVsyst photovoltaic software.

The Briar Creek solar farm is about 40 miles south of Dallas, and is expected to start commercial operation at the end of 2021.

POWER, FINANCE & RISK: Big data gets smarter on vPPAs

“We were delighted by the contribution [vPPAs] made to our sustainability goals but were frustrated by the financial volatility of the settlement payments and the limited ability we had to predict or manage that volatility,” wrote Kenneth Davies when he was director of energy portfolio management at Microsoft. Working with insurer Allianz and analytics firm REsurety, Davies came up with solutions including the proxy generation PPA, the volume firming agreement and the settlement guarantee agreement.

Iron Mountain teams with Birch Infrastructure & REsurety to de-risk clean energy procurement

REsurety helps Iron Mountain limit its exposure to variable weather and power markets, to achieve both sustainability and financial goals while investing in offsite renewable energy.

Birch Infrastructure has created a customized solution that will enable data center leader Iron Mountain, Inc. to continuously and cost-effectively power its data centers in five states with renewable power. That energy, produced at the Ringer Hill Wind Farm in Pennsylvania and the Dermott Wind project in Texas, will be financially firmed up into a reliable 24/7 power solution, thereby avoiding the cost and complexity standard in traditional renewable energy purchases.

Iron Mountain had previously announced its Ringer Hill and Dermott wind power agreements in 2016 and 2017. Mark Kidd, Iron Mountain’s Executive Vice President and General Manager of Data Centers, commented: “Iron Mountain’s Data Center business has been powered with 100% renewable energy since 2017. Power Purchase Agreements with projects such as Ringer Hill and Dermott are a key part of that strategy. Birch has enabled us to manage the risks inherent in this type of agreement and confidently enter into additional agreements to responsibly power our rapidly growing data center footprint.”     

“Utilizing risk management tools and assembling the right team is how we’re able to help partners like Iron Mountain meet their renewable energy and financial goals,” said Kenneth Davies, Chief Strategy Officer at Birch. “Our aim with all of our clients is to reduce the risk and uncertainty that comes with renewables while providing clean energy reliably and cost-effectively. That’s what we were able to do for Iron Mountain.”

To help reduce risk and costs and simplify renewable energy for Iron Mountain, Birch teamed up with REsurety, a provider of valuation analytics and risk management services in the renewable energy market. Specifically, Birch incorporated two weather-linked risk management products to improve on the standard virtual Power Purchase Agreement (vPPA) – a Settlement Guarantee Agreement (SGA) and a Volume Firming Agreement (VFA).

These tools allow corporate clean energy purchasers to limit their exposure to variability from weather and power market fluctuations while investing in offsite renewable energy. Birch executed the SGA and VFA for Iron Mountain with Allianz Global Corporate & Specialty’s Capital Solutions unit, in collaboration with Nephila Climate. REsurety provided the valuation and risk analytics in support of the transactions, and will serve as the calculation agent for their ongoing tracking and settlement.

“vPPAs are great tools for corporates to achieve their sustainability goals,” said Lee Taylor, CEO of REsurety. “Unfortunately, on their own they can result in ineffective hedges on energy consumption costs or speculative exposure to commodity markets and weather. Birch and Iron Mountain recognized these challenges, and we are delighted to have supported their transition to this new solution – ensuring Iron Mountain achieves its sustainability goals and its financial goals, simultaneously.”

Taaleri SolarWind II fund invests in a 336 MW ready to build wind farm in Texas

Taaleri Energia announces the use of a 10-year Proxy Revenue Swap for its 336 MW Texas wind farm. REsurety provided risk analytics supporting the transaction, with the substantial majority of the power to be contracted under the PRS.

The Taaleri SolarWind II fund has, together with AIP, Ilmarinen, and Akuo Energy, acquired 93% of the equity in the Escalade wind farm in Texas. Taaleri Energia, the project developer, will retain a minority stake in the project. The wind farm is located in Knox County, around 300kms west of the Dallas-Fort Worth metropolitan area.

The wind farm will consist of 45 Vestas V162 5.6 MW turbines and 20 Vestas V150 4.2 MW turbines and represents a USD 450 million plus investment in the North American renewable power sector. The construction work is scheduled to begin during Q2 2020 with the wind farm reaching operational status in Q4 2021.  The wind farm’s annual production of electricity will be approximately 1270 GWh. It will produce enough electricity to supply around 115,000 households and will offset the equivalent of 604,000 tonnes of carbon dioxide during each year of operation.

The project has been developed in-house by Taaleri Energia since 2018, following an acquisition from its development partners NorthRenew Energy and Chermac Energy. The Balance of Plant contractor is Mortenson Construction and Akuo Energy is the Construction Manager as well as the Technical and Commercial Manager for the project. Vestas will provide Operations & Maintenance services for the project under a 30-year contract.

Tax equity for the investment will be provided by BHE Renewables (a subsidiary of Berkshire Hathaway Energy) and construction financing by NORD/LB, Mizuho, Santander and Societe Generale. The substantial majority of the power produced by the wind farm will be contracted under a 10-year Proxy Revenue Swap with Allianz Global Corporate & Specialty SE’s Capital Solutions unit in collaboration with Nephila Climate.  REsurety Inc. provided risk analytics supporting the transaction.

“We are extremely happy with the first investment in the US from the Taaleri SolarWind II fund. The onshore wind resource in Texas is excellent and the location of our wind farm, with connections to the large population centres, is also ideal. The ERCOT market for electricity in Texas is very similar in structure and operation to the Nord Pool electricity market in the Nordic countries, a market that we are very familiar with. The fact that we have developed this project in-house and succeeded in bringing on board such high calibre partners, co-investors and financers is a testament to the strength of our development, engineering and investment capabilities”, said Taaleri Energia’s Managing Director, Kai Rintala.

 “Onshore wind in Texas presents its very specific peculiarities which we managed with innovative solutions. This transaction marks the beginning of a partnership with Taaleri and Akuo Energy. Two highly reputable players in the sector. We are pleased to have partnered with them and we are looking forward to continuing and developing our strong partnership going forward”, adds Domenico Tripodi, Partner at AIP.

“Akuo is excited to form its first partnership with Taaleri and AIP, companies who share similar values and DNA to ours and are keenly focused on accelerating the global energy transition.  The addition of the 336 MW Escalade project to Akuo’s operating portfolio is a significant step forward in meeting Akuo’s growth ambitions globally and we are thrilled that Taaleri and AIP have placed their trust in Akuo as an equity and operating partner” stated Thomas Coté, CEO Akuo Energy USA, Inc.

Scout Clean Energy completes construction of 180-MW Heart of Texas Wind Farm

Scout Clean Energy reaches commercial operations at Heart of Texas. REsurety provided risk analytics to support a Proxy Generation PPA for the project.

Colorado-based renewable energy developer, owner and operator, Scout Clean Energy, completed construction and successfully closed tax equity funding for the utility-scale 180-MW Heart of Texas Wind Farm (HTX) in McCulloch County, Texas. Scout is a portfolio company of Quinbrook Infrastructure Partners.

HTX utilizes 64 of the latest generation GE 2-MW platform wind turbines and three models of 2-MW platform turbines to optimize site production. Construction began in September 2019 and was completed following the commissioning of Scout’s 300-MW Ranchero Wind Farm in Crockett County, Texas late last year.

Scout entered a fixed-price balance-of-plant construction agreement with RES Americas Construction, who completed the construction. The asset management and post-construction operation will be undertaken by Scout.

Allianz Global Corporate & Specialty’s Capital Solutions unit, in partnership with Nephila Climate, has entered into a pgPPA with the project company. A pgPPA is the newest structure in a suite of risk management tools that allows buyers and sellers of renewable energy to manage the risks created by weather-driven renewable energy, which provides an alternative offtake arrangement guaranteeing a rate per MWh to the project for its proxy generation. REsurety provided the risk analytics supporting this long-term offtake transaction.

Construction financing of $255 million was provided by KeyBank as an Administrative Agent, Rabobank and CoBank ACB. GE Energy Financial Services and BHE Renewables invested tax equity. The project has tax incentive agreements in place with McCulloch County, McCulloch County Hospital District and Lohn Independent School District. It is estimated that the county will receive $36 million in tax revenue over the life of the project.

“Heart of Texas was completed on time and under budget which is quite an achievement given the wide-spread disruption that COVID-19 has caused across the entire US economy,” said Michael Rucker, CEO and founder of Scout Clean Energy.

“Reaching commercial operations at Heart of Texas brings Scout’s operational portfolio of wind energy generation to 698 MW with a further 146 MW under construction and more than 4,000 MW in our active development pipeline.”

REsurety launches REmap, expanding the industry’s access to critical value & risk analytics

Map-based SaaS tool provides unprecedented transparency and insight into clean energy markets, illustrating today how COVID-19 has impacted renewable projects and driven record-setting low prices.

BOSTON, May 28, 2020 /PRNewswire/ — A new information services product that harnesses a massive project performance dataset and suite of financial analytics that industry leaders use to make long-term asset and contract decisions for wind and solar energy has revealed that the low energy demand during the coronavirus shutdown, combined with low natural gas prices and high renewable generation, has resulted in unprecedented low power prices in multiple U.S. markets.

REsurety, the industry leader in clean energy valuation and risk analytics, said the insights available from its Renewable Energy Market Analytics Platform (“REmap”) include that the production-weighted wholesale price of electricity for wind projects fell to all-time lows during the COVID-19 pandemic across markets including SPP, PJM and MISO – with extreme lows reaching below $2 per MWh for the entire month of April in high wind penetration regions such as Oklahoma.

REsurety today is publicly announcing the launch of its REmap information service. The REmap tool integrates weather and power market data at an unprecedented scale, calculating hourly financial performance for 15,000 operational and greenfield locations, which REsurety uses to provide clients with the industry-wide context and site-specific depth of insight needed to make better decisions faster. 

“We’re expanding the access to our secret sauce,” said REsurety CEO Lee Taylor. For years, REsurety has used its proprietary data and analytics to support the analysis of hedging instruments. Now, through REmap, REsurety makes that insight available by subscription to support a much broader set of use cases, including greenfield prospecting, M&A diligence, and offtake and hedge analysis.

“Clean energy markets are going through a revolution,” Taylor added. “The scale and complexity of risks facing clean energy projects and their offtakers are at an all-time high. Understanding and managing those risks requires a step change in information – and that’s why we built REmap.”

REmap leverages REsurety’s unique expertise at the intersection of atmospheric science, power market modeling and big data. Billions of data points from many sources are collected, cleansed, and analyzed to provide the financial metrics that are critical to renewable energy decision makers’ success. Existing customers include developers, hedge providers, C&I buyers, and advisors.

“REmap is a sea change in the access to quantity and quality of data,” said Joan Hutchinson, Managing Director of Marathon Capital, an early REmap client. “It has assisted Marathon in providing our clients with data-driven insights and solutions efficiently – even before project data is shared.”

Jim Howell, CEO of Birch Infrastructure, also a REmap client, commented, “Identifying the optimal location to invest in renewables has always been somewhat of a dark art – relying on intuition and point-specific analyses. REmap gives us the information we need to truly optimize our procurement and hedging activities.”

Nephila Climate Adds Proxy Generation PPA To Its Suite Of Hedging Structures For Renewable Energy

Hedging structure allows Scout Clean Energy to manage risks associated with weather and price variability for its Heart of Texas wind farm.

HAMILTON, Bermuda, Oct. 4, 2019 /PRNewswire/ — Nephila Climate, the weather, climate and ESG-driven specialty division of Nephila Holdings Ltd. announced the first use of a Proxy Generation Power Purchase Agreement (pgPPA) for the 180MW Heart of Texas (HTX) wind farm located in McCulloch County Texas being developed by Scout Clean Energy of Boulder, Colorado. Scout secured the pgPPA with Allianz Global & Specialty, Inc.’s Alternative Risk Transfer unit, in partnership with Nephila Climate. REsurety provided the risk analytics supporting the long-term offtake transaction and will serve as the calculation agent for the life of the contract.

The pgPPA is the newest structure in a suite of risk management tools that allows buyers and sellers of renewable energy to manage the risks created by weather-driven renewable energy. Unlike the Proxy Revenue Swap (PRS) (more than 2GWs of PRSs are currently deployed) which guarantees a revenue amount, the pgPPA guarantees a rate per MWh. The project therefore retains exposure to P50 accuracy. This structure provides the cashflow certainty the project needs to support financing but does not require the project to pay for the transfer of risk that it prefers to retain.

“The renewable energy landscape continues to evolve, with buyers and sellers of clean energy having to manage increasingly large and complex risks,” said Richard Oduntan, CEO of Nephila Climate.  “In response to that need, Nephila Climate’s goal is to provide a holistic set of risk management tools to the buyers and sellers of clean energy.  These tools enable our clients to pick and choose which risks they want to shed, and which risks they want to hold, which can change project by project. We’re delighted to be announcing the execution of this new structure with the Scout team a short few months after announcing our PRS transaction with them earlier this year.”

A pgPPA is essentially the same as the popular Virtual PPA, or “vPPA” structure favored by corporate buyers. The difference is that the contract settles on a Proxy Generation index rather than the observed or metered generation. Proxy Generation is an hourly index that specifies the volume of energy that a project would have produced if it had been operated as specified by the developer or owner. This settlement mechanism is required to establish aligned interests: ensuring that the offtaker doesn’t take on financial exposure to the owner/operator’s decisions, such as when to plan maintenance or to install upgrades.

“The success of structures like the Proxy Revenue Swap for project developers, and more recently the Volume Firming Agreement (VFA) for renewable energy buyers, clearly demonstrates that both buyers and sellers of clean energy are increasingly in search of tools to manage the volatility of intermittent generation,” said Lee Taylor, CEO of REsurety. “The pgPPA is simply the next iteration of a proven structure that enables each party to manage the risks that they are best equipped to hold.”

“We continue to break new ground with these innovative risk management structures,” stated Karsten Berlage, managing director, Allianz Alternative Risk Transfer (ART). “We are pleased to collaborate with the Nephila Climate and REsurety teams yet again for another ‘first,’ and to provide Scout with the revenue certainty they needed to launch construction of the project.”

REsurety Surpasses 5 Gigawatts of Renewable Energy Risk Mitigation Contracts

REsurety-enabled risk mitigation products have become standard operating procedure for clean energy industry leaders.

BOSTON, Jan. 9, 2019 /PRNewswire/ — REsurety, a leading provider of valuation analytics and risk management services to the buyers and sellers of renewable energy, announced today that it has reached a critical corporate and industry milestone, having surpassed more than 5,000 MW of risk management transactions. Transactions closed in 2018 with Microsoft, Enel Green Power North America, Engie, Orsted, Macquarie, and several other large international companies have fueled nearly half that cumulative volume in 2018 alone, signaling broad and accelerating adoption of REsurety’s risk mitigating products and services. 

“2018 has been a breakout year for REsurety and for the industry’s adoption of risk management tools,” said Lee Taylor, CEO of REsurety. “Our 5GW milestone shows the incredible demand for certainty when it comes to buying and selling renewables. Both project owners and their corporate off-takers are finding our risk mitigation products to be an accessible and cost-effective way to avoid revenue or cost volatility.”

REsurety Deployment of Renewable Energy Risk Mitigation Products

REsurety’s success in 2018 was highlighted by several high-profile transactions. As separately announced on Jan. 4th, 2019, Enel Green Power North America has utilized the Proxy Revenue Swap (PRS) hedging structure to support the revenues of 295 MW of its 450 MW High Lonesome wind project in Texas – marking it the largest PRS ever signed.

“The wind industry has made great strides in driving down costs over the last decade,” said Hannah Hunt, Deputy Director for Electricity Policy and Demand, American Wind Energy Association (AWEA). “More recently we have seen improvements in driving down soft costs and REsurety’s approach of using weather and pricing data to reduce volatility risk is another great success story for the industry.”

Recent announcements by clean energy pioneers such as Microsoft in the U.S. and Orora in Australia demonstrate that buyers of renewable energy are also embracing REsurety products to manage the volatility associated with their purchases of clean energy. Both companies, as well as a third, undisclosed corporate buyer, contracted for products that will help them manage the cost volatility of their renewable energy purchases and will become an ongoing part of their procurement processes. In 2018 REsurety closed 19 new transactions across its Proxy Revenue Swap, Volume Firming Agreement (VFA), Balance of Hedge and Proxy Generation PPA product lines.   

“Taking on and managing the risks associated with vPPAs has become a real hurdle for corporate purchasers of renewable energy,” said Roberto Zanchi from Rocky Mountain Institute’s Business Renewables Center. “The early success of risk mitigation contracts as a standard part of the procurement process sets a strong precedent for other companies who are similarly eager to achieve sustainability goals while mitigating financial risk exposure.”

As the global clean energy industry matures, the combined risks of power market volatility and intermittent fuel sources have migrated away from governments and utilities to the producers and end-consumers of clean energy.  That increasing complexity and scale of risk requires a new breed of information and risk management products. REsurety has led the way in developing those tools in collaboration with Allianz Global Corporate & Specialty, Inc’s Alternative Risk Transfer unit, Nephila Climate and more recently Microsoft.

REsurety’s expertise in weather and energy market price information serves as the foundation for the successful insurance products that are offered by REsurety’s partners Nephila and Allianz. REsurety’s extensive proprietary data systems for weather and energy markets provides insight into the value and risk of weather-fueled renewable power generation. This constantly growing and expansive dataset, and related analytics, enables REsurety and its partners to offer a range of risk mitigation products catered to meet the specific needs of clean energy buyers and sellers.

Nephila Climate Announces First Proxy Revenue Swaps for Wind Project Re-Powering

Ares Management uses PRS structure to protect long term cash flows from a three-project portfolio in ERCOT totaling approximately 400MW of nameplate capacity.

HAMILTON, Bermuda, Feb. 28, 2019 /PRNewswire/ — Nephila Climate (“NCx”), the weather and ESG-driven specialty division of Nephila Holdings Ltd. announced the first use of a Proxy Revenue Swap (“PRS”) for the re-powering of a wind project. Ares Management Corporation, a leading global alternative asset manager, is the first to utilize the PRS structure for a repowered project. A PRS is a hedging contract that provides renewable energy projects with protection against exposure to the risks inherent in relying on a weather-driven fuel source, in addition to power price volatility.

A fund managed by Ares’s Infrastructure and Power strategy used three different PRS contracts to facilitate the financing for the acquisition and re-powering of the wind power portfolio from BP in the ERCOT region. The three-project portfolio included Sherbino Mesa 2, Trinity Hills and Silver Star.

“Just as the PRS has now become a standard product for de-risking merchant renewable energy projects, we expect it to play a key role in helping sponsors to finance the repowering of wind projects,” said Richard Oduntan, CEO of NCx. “With a forecasted surge in repowering projects over the next several years, we are pleased that the Ares PRS transactions will be the vanguard of many more to come.”

The projects entered into ten-year PRS contracts with Allianz Global Corporate & Specialty, Inc.’s Alternative Risk Transfer (ART) unit, in partnership with Nephila Climate. REsurety, Inc. provided the risk analytics needed to support the PRS transactions and will serve as the calculation agent on an ongoing basis.

“We continue to break new ground with PRS in using it to support the re-powering of wind projects,” stated Karsten Berlage, managing director, Allianz ART. “We are pleased to collaborate with NCx yet again on another ‘first,’ and to help ARES manage the long-term revenue risks for these projects.”

According to Bloomberg New Energy Finance, the market for re-powering is expected to surge in the next two years with 1.25 and 2.02 GW of re-power projects predicted to be completed in 2019 and 2020, respectively, in the US alone.

Investment in the construction of High Lonesome amounts to approximately 600 million US dollars and is part of the investment outlined in Enel’s 2019-2021 strategic plan. The project is currently financed through the Group’s own resources and is expected to enter into operations by the end of 2019. Once fully operational, the wind farm will be able to generate around 1.7 TWh annually, while avoiding the emission of over 1.1 million tons of CO2 per year.

Enel has entered into a PRS for a 295 MW portion of the project with insurer Allianz Global Corporate & Specialty, Inc.’s Alternative Risk Transfer unit (Allianz), and Nephila Climate, a provider of weather and climate risk management products. The PRS is a financial derivative agreement designed to produce stable revenues for the project regardless of power price fluctuations and weather-driven intermittency, hedging shape risk in addition to risk associated to price and volume.

Under this agreement, High Lonesome will receive fixed payments based on the expected value of future energy production, with adjustments payed depending on how the realised proxy revenue of the project differs from the fixed payment. The PRS for High Lonesome, which is the largest by capacity for a single plant globally and the first agreement of its kind for Enel, was executed in collaboration with REsurety, Inc., a leader in renewable energy risk management and information services.

The construction of High Lonesome is a strong testament to the popularity and success of innovative renewable energy protections,” said Karsten Berlage, Managing Director, Allianz Risk Transfer. “The majority of today’s stakeholders champion the continued growth of renewables and that is why Allianz is committed to flexible strategies such as the PRS that mitigate those risks – long term.

Renewable energy projects are under increasing pressure to deliver predictable returns despite the increasing volatility of the value of intermittent generation,” said Lee Taylor, Co-Founder and CEO, REsurety. “We developed the Proxy Revenue Swap specifically to deliver unrivalled certainty of cash flows, regardless of power price volatility and weather-driven intermittency. We are delighted to have had the opportunity to collaborate with Enel, Allianz and Nephila to bring the largest PRS transaction to fruition.

In Texas, Enel currently operates the 63 MW Snyder wind farm, located in Scurry County.

Enel Green Power North America, part of Enel Green Power, is a leading owner and operator of renewable energy plants in North America with projects operating and under development in 24 US states and two Canadian provinces. The company operates around 100 plants with a managed capacity of around 5 GW powered by renewable hydropower, wind, geothermal and solar energy.

Microsoft: Buying renewables should be easy

Microsoft discusses their co-development and adoption of Volume Firming Agreements: a tool that enables PPAs to more effectively serve as protection against energy price fluctuations.

Buying renewable energy should be easy — here’s one way to make it less complex

By Brian Janous, Microsoft General Manager of Energy and Sustainability; Kenneth Davies, Microsoft Director of Innovation for Energy Strategy & Research; and Lee Taylor, cofounder and CEO, REsurety

It would be difficult to overestimate the impact that corporate procurement of renewable energy, primarily through power purchase agreements (PPAs), has had on the overall renewable market. In less than a decade, renewable energy created from corporate PPAs went from zero to more than 13 gigawatts in the U.S. alone.  Microsoft is one of the largest players in this market, beginning with a 110-megawatt wind project in Texas in 2013 to a portfolio of more than 1.2 gigawatts in six states and three continents.

This rapid growth, both within our portfolio and beyond, is because these deals are good for business. Renewable energy agreements help companies meet sustainability commitments customers increasingly expect and – if structured properly – do so in a way that provides a hedge against the risk of rising electricity costs on the open market. The fuel for renewable energy projects – the wind and the sun – are free, enabling a fixed price over the length of the agreement. However, as the market has matured, it’s become clear that other risks and complexities exist within the PPA structure that may inhibit their effectiveness as risk management tools. The failure to simplify this complex process and mitigate the risk assumed by the buyer could endanger the corporate procurement market, causing it to slow or stall out completely.

We want to see continued growth of renewables. That is why today, Microsoft and REsurety, along with their partners at Nephila Climate (“Nephila”) and Allianz Global Corporate & Specialty, Inc.’s Alternative Risk Transfer unit (Allianz) announced a new solution that mitigates those risks. We’re calling it a volume firming agreement (VFA), and Microsoft, in addition to co-developing it, will become the first adopter.

The concept of a VFA has its roots in late 2010, when Nephila Capital approached several of the first corporate renewable energy buyers with the idea of helping them manage the risks inherent in PPAs. At the time, however, the idea was just that. Unable to find a corporate buyer willing to put in the effort to help co-develop what would become the VFA, Nephila elected instead to sponsor an MBA project at the Tuck School of Business at Dartmouth College, led by Lee Taylor. Upon graduation, Taylor turned that concept into a company, REsurety. In 2016, Nephila and REsurety finally found that corporate partner in Microsoft, when we signed a PPA with Allianz for the output of the 178-megawatt Bloom wind project in Kansas. This was the first Proxy Generation PPA, winning honors as North American Wind Project of the Year, and laying the groundwork for today’s VFA.

VFAs are intended to be a simple fix to a big challenge with renewable energy PPAs, namely that these deals expose the buyer to all the weather-related risks of power production, and the inherent intermittent nature of wind and solar means there are hourly issues to be addressed. Put simply, the power needs of buyers are static but the power from the project varies on a day-to-day, hour-to-hour basis.

While it’s true that the fixed-price nature of PPAs provide the buyer some protection against a long-term increase in price, the hourly variability of wind and solar creates near-term complexity and risk. In periods when the wind or solar project is producing more than average, the market value of this energy is often lower due to the impact of additional supply in the market. Conversely, in periods when it is producing less than average, the market price is often high.  In other words, volume and price move inversely. This variability and the financial impact are difficult for even the savviest energy buyers and a substantial deterrent to smaller companies, as well as retailers, looking to engage in the renewables market.

But what is undesirable to buyers is very attractive to others, namely insurance companies whose core business revolves around taking weather-related risks, including temperature, rain, snow, wind and so on. VFAs effectively remove the risk related to how future weather conditions will impact the financial value of a PPA from buyers and reallocates it to people who want that risk.

As the market for VFAs and similar products grow, we believe it will create new incentives for those who now bear these risks to procure storage resources and other assets capable of physically balancing the intermittency of renewables. Through the aggregation of risk, these insurers will be able to procure resources at economies of scale that even Microsoft is unable to achieve. In that way, today’s financial firming solution is tomorrow’s physical firming solution, accelerating the adoption of storage and other resources required to eventually transition to a 100 percent carbon-free power generation system.

VFAs are not a replacement for PPAs, nor are they a product Microsoft is selling. They are contracts that simply sit atop new PPAs, or existing PPAs, mitigating the risk to the buyer. Microsoft has signed three of these contracts with Allianz, in conjunction with their partners at Nephila, covering three wind projects in the U.S. in Texas, Illinois and Kansas, totaling almost 500 megawatts. As Microsoft continues to purchase renewable energy to power our operations, we anticipate utilizing VFAs to firm the energy and match our consumption on an hourly basis.

At Microsoft, we are committed to driving a more sustainable future beyond our own four walls. That is why our corporate energy commitments are far broader than just megawatts. We intend to support and enable the transformation of the energy sector using our buying power and innovations so everyone can benefit. REsurety is also focused on enabling the growth of renewable energy by providing tools to understand and manage risks.

The partnership between our two organizations leverages deep expertise in markets, risk and the challenges buyers face in these markets. That is why we’re confident that innovations like the VFA will make it cheaper and easier to procure renewable energy, enabling corporate buyers of all sizes, as well as retailers, to play a role in enabling the transition from fossil fuels to clean energy.

We invite other corporate buyers to take a more in-depth look at our white paper expounding on the role of Proxy Generation PPAs in the implementation of VFAs, co-authored by Microsoft, REsurety and Orrick, Herrington and Sutcliffe LLP, available today here, or contact us. We’re looking forward to a future where even more corporations can participate in the renewable energy market, which would be a big step toward a low-carbon future for the planet.

Bloom Wind recognized as North American Wind Deal of the Year

Capital Power’s Bloom Wind is recognized for its use of the first Proxy Revenue Swap hedging structure to secure long term revenues.

EDMONTON, AB–(Marketwired – March 16, 2017) – Capital Power’s Bloom Wind project was recognized by infrastructure journal and project finance magazine, IJGlobal, as the North American Wind Deal of the Year. The annual IJGlobal Awards, which recognize and celebrate the best in energy and infrastructure deals over the past year, were handed out in New York on March 15, 2017.

Capital Power’s Bloom Wind project earned the award recognition for the use of an innovative 10-year Proxy Revenue Swap agreement with Allianz Risk Transfer (ART), a subsidiary of Allianz SE, the worldwide insurance and asset management group, covering 100 per cent of the project’s output. The unique product was created and commercialized through a partnership amongst ART, Nephila Capital Ltd., REsurety Inc. and Altenex LLC, which swaps the floating revenues of the wind farm — those driven by the hourly wind resource and power prices — for a fixed annual payment.

“We’re proud to pioneer the use of this innovative risk-management solution for hedging potentially volatile revenues of wind farms at Bloom Wind,” said Paul Wendelgass, Capital Power Director, Business Development. “The agreement secures long-term predictable revenues for investors, which provided an opportunity for Capital Power to secure a renewable energy tax-equity investment for Bloom Wind with Goldman Sachs Alternative Energy Group in December 2016.”

The first-of-its-kind product was developed by ART to help project owners manage the revenue volatility associated with the wind resource variability related to large-scale wind projects. Capital Power is among the first Independent Power Producers in North America to utilize a proxy revenue swap agreement as a risk-management solution for hedging revenue volatility of wind farms. The product is an alternative to securing a traditional contracted off-taker through a Power Purchase Agreement and has potential to be replicated for other renewable projects in the U.S. and globally.

“This pioneering solution enables both investors and corporations alike to launch sizable renewable energy projects, and is a key growth area for Allianz,” said Karsten Berlage, Managing Director at Allianz Risk Transfer. “By circumventing high up-front costs associated with clean energy, these projects will be brought online at a much faster pace and we are very proud to partner with Capital Power and to support Microsoft’s largest wind energy purchase to date.”

In November 2016, Microsoft Corp. became the first buyer to participate in this structure, acquiring the environmental attributes connected to Bloom Wind from ART for a 10-year period. The combined output from Bloom and a Wyoming wind farm will produce enough energy on an annual basis to cover the annual energy used at Microsoft’s Cheyenne, Wyoming, datacenter.

“Microsoft is constantly looking for new ways to accelerate the adoption of clean energy,” said Christian Belady, general manager of cloud infrastructure strategy and architecture at Microsoft. “We worked closely with ART and Capital Power to come up with the innovative finance model. This approach has the potential to bring more clean energy online, faster, and we’re proud that our participation helped make this project a reality.”

The 178 megawatt Bloom Wind project, located in Kansas is situated within one of the strongest wind regimes in the U.S. Construction of the project began in August 2016 and is expected to be completed on time and on budget in the third quarter of 2017.

Apex Clean Energy discusses their use of Proxy Revenue Swaps to expand clean energy

David Clemens, Apex Clean Energy’s Director of Finance, discusses how the innovative Proxy Revenue Swap hedging structure has enabled Apex to bring more clean energy to market.

This past summer, Apex closed on the joint financing for the Cotton Plains Wind, Old Settler Wind, and Phantom Solar energy facilities, all located in Texas. One of the many unique features of the transaction was our employment of a novel financial hedge product called a proxy revenue swap, or PRS, for Old Settler Wind. Without the economic certainty that the PRS brings to that project, Apex would not have been able to source the roughly $330 million in debt and equity capital necessary to build and operate the facilities. But because the PRS was relatively new and not well understood in the financial markets, its presence at Old Settler presented unique challenges during the financing process.

Innovation Expands Investment Opportunities

Financial hedges are not new to the energy industry. A more common version, often called a fixed-for-floating swap, is well understood in the market. In a typical fixed-for-floating swap, a project will sell the electricity it generates into the spot, or merchant, market. The price of energy in the spot market is in constant flux, and in certain circumstances can fluctuate wildly from hour to hour. The vast majority of project financing parties will not invest in a project selling power into the spot market because they are uncomfortable with the cash flow instability, which increases the uncertainty that their investment will be repaid. To counter this risk and make the project more attractive to financing parties, the project owner will enter into an agreement with a counterparty—typically a bank or an energy company—whereby the counterparty will agree to pay the project a fixed price for energy generated by the project, in return for the value that the project receives from the spot market. For instance, let’s say Old Settler Wind agreed to a swap at a price of $30 per megawatt-hour (MWh). Then, if Old Settler were to sell one MWh into the ERCOT market at $20, it would transfer this $20 to the swap counterparty, and the swap counterparty would transfer $30 back to Old Settler. Likewise, if the MWh sold for $35, the project would send $35 to the swap counterparty, and the swap counterparty would still send $30 back to Old Settler. Thus, the project is swapping the “floating” price received for that MWh (i.e., $20 or $35) for the fixed price of $30. This arrangement allows the project to rely on a steady cash flow—$30/MWh—which investors can rely on when calculating their expected investment return.

Eliminating Wind Production Risk to Enhance Deal Value

Under a traditional fixed-for-floating swap, however, the swap counterparty will not take a position on how many MWh a project is expected to produce (in other words, they do not want to take the risk relating to the productivity of the wind resource). To avoid this, traditional swap counterparties will only agree to swap the P99 volume produced by the project (that is, the MWh that a project can be expected to produce with 99% certainty). As a result, all of the energy that a project generates above the P99 generation level is not subject to the swap; this energy is sold into the spot market without the benefit of a fixed price. Because most investors place a lower value on the energy that does not have a guaranteed price, they discount this post-P99 production when sizing their investment amount. Depending on the specifics at a particular wind project, the amount of post-P99 production can be considerable, and failing to account for this production can lead to a dramatically reduced investment from financing parties.

Enter the proxy revenue swap. At its core, the PRS guarantees a project a fixed amount of revenue, regardless of how many MWh the project actually produces. Thus, even if the wind doesn’t blow for an entire year—and likewise the wind farm doesn’t generate any electricity—the project will still receive revenues from the PRS counterparty. In return, the project will turn over all the revenues that it actually receives from selling its energy into the spot market over that same period of time. The amount of revenue guaranteed under a PRS is primarily a function of the counterparty’s evaluation of the project’s wind profile (PRS counterparties are often insurance companies with experience evaluating weather-related risk).

Put simply, a traditional fixed-for-floating swap takes price risk off the table. The PRS takes this concept one step further by also taking wind production risk off the table. This results in more guaranteed revenue for the project, thus allowing the project to finance a greater portion of its capital costs.

Although the PRS counterparty is comfortable taking price risk and wind risk, it does not take operations or basis risk—those stay with the project. In oversimplified terms, operations risk is the risk that the project will not convert wind into electricity as efficiently as expected due to operational issues such as turbine maintenance. Basis risk is the risk that the electricity price at the “hub”—where electricity is traded on the spot market—will be less than the electricity price at the actual  location, or “node,” where the electricity enters the grid. (Basis is a complicated topic beyond the scope of this article, but the most common reason for differences in hub and node prices is inadequate transmission.)

Putting the PRS to the Test

The novelty and complexity of the PRS came into focus when Apex began the financing process. Investors tend to prefer projects and concepts that are well understood—no one wants to lend money on the basis of a new product that turns out to be fundamentally flawed. For this reason, each of the sponsor equity, debt, and tax equity investors undertook a detailed review of the PRS and insisted on being fully satisfied with its risk profile prior to funding. Unlike the vast majority of their investments, the investors had no previous experience with this product; they had to learn everything from scratch. The detailed review included analysis by multiple independent engineers, consultants, and law firms, as well as the investors’ in-house legal, accounting, and engineering teams.

This painstaking due diligence process placed a substantial burden on Apex. Many of my colleagues in the asset management, power marketing, resource assessment, and legal departments will recall a seemingly endless series of conference calls to explain how the PRS works and to structure the transaction to fit the needs of the investors. All of this was in service of helping five different investors complete their diligence and commit their share of roughly $330 million in capital costs. At the end of the process, our financing efforts were successful, and the Cotton Plains Wind, Old Settler Wind, and Phantom Solar projects are now under construction.

Benefits of the PRS

A long-term power purchase agreement (PPA) with an investment-grade counterparty remains the gold-standard revenue option for financing a wind project. Apex’s power marketing team has been actively searching for alternative revenue sources capable of standing up to the scrutiny of the financing process. Apex successfully closing on the financing for the trio of Texas projects in July 2016 demonstrates that the PRS fits this mold.

In fact, the PRS has already become a powerful asset in our power marketing toolbox. Shortly after closing on the hybrid portfolio, we successfully incorporated a PRS for a portion of the generation at our Grant Plains Wind project in Oklahoma, which closed in August and is currently under construction.

And Apex is now actively modeling the PRS at many of our other projects. We believe the PRS will remain a viable path to market complementing traditional PPAs and financial hedges, and we expect the PRS financing process to become smoother as we apply the lessons learned from these recent projects.

Microsoft buys power from Bloom Wind Farm

Microsoft collaborates with Capital Power and Allianz Risk Transfer to buy clean power from Bloom Wind Farm – in connection with the project’s existing Proxy Revenue Swap.

REDMOND, Wash. — Nov. 14, 2016 — On Monday, Microsoft Corp. announced its largest purchase of wind energy to date with the signing of two agreements. Combined, these agreements represent 237 megawatts of wind energy, which brings Microsoft’s total investment in wind energy projects in the U.S. to more than 500 megawatts.

“Microsoft is committed to building a responsible cloud, and these agreements represent progress toward our goal of improving the energy mix at our datacenters,” said Brad Smith, president and chief legal officer at Microsoft. “Our commitment extends beyond greening our own operations because these projects help create a greener, more reliable grid in the communities in which we operate.”

Microsoft has contracted with Allianz Risk Transfer (ART) to fix its long-term energy costs and purchase the environmental attributes connected with the new, 178-megawatt Bloom Wind project in Kansas. The project is the first to use a novel structure developed by ART and designed to offset high upfront costs associated with the creation of large-scale wind projects. Microsoft is the first buyer to participate in this structure, which has the potential to bring clean energy projects online at a faster pace.

“It is important for investors in renewable energy projects to secure long-term, stable revenues, and our structure does just that,” said Karsten Berlage, managing director of ART. “We are thrilled to be partnering with Microsoft on this groundbreaking project.”

In addition, Microsoft has contracted with Black Hills Corp. subsidiary Black Hills Energy, under a long-term agreement, to purchase 59 megawatts of renewable energy certificates from the Happy Jack and Silver Sage wind projects, which are adjacent to Microsoft’s Cheyenne, Wyoming, datacenter. The combined output of the Bloom and Happy Jack/Silver Sage projects will produce enough energy on an annual basis to cover the annual energy used at the datacenter.

“Our longstanding partnership with Microsoft productively led to this landmark collaboration. This collaboration provided them the opportunity to utilize significantly more renewable energy while still ensuring the reliability they’ve come to expect through our energy infrastructure and generation resources,” said David R. Emery, chairman and CEO of Black Hills Corp. “We are proud to be a strong supporter and partner in their mission to power their datacenters with increased renewable energy resources, and look forward to our continued collaboration in the years ahead.”

Microsoft and Black Hills Energy also worked together to create a new tariff, available to all eligible customers, that allows the utility to tap the local datacenter’s backup generators, thereby eliminating the need for Black Hills Energy to construct a new power plant. The tariff received approval from the Wyoming Public Service Commission in July.

“We are constantly looking for new ways to approach energy challenges and avenues of engagement with our utility partners,” said Christian Belady, general manager of cloud infrastructure strategy and architecture at Microsoft. “The team worked closely with ART to come up with a completely new model to enable faster adoption of renewables. Likewise, the tight engagement with Black Hills created the opportunity for Microsoft’s datacenter to become an asset for the local grid, maintaining reliability and reducing costs for ratepayers. This kind of deep collaboration with utilities has great potential to accelerate the pace of clean energy, benefitting all customers — not just Microsoft.”

These are Microsoft’s third and fourth wind energy agreements, joining the 175-megawatt Pilot Hill wind project in Illinois and 110-megawatt Keechi wind project in Texas. In March, Microsoft also signed an agreement with the Commonwealth of Virginia and Dominion Energy Inc. to bring 20 megawatts of solar energy onto the grid in Virginia. These projects are in addition to the renewable and carbon-free energy Microsoft purchases from the grid mix in the markets in which it operates.

Allianz, Nephila, REsurety & Altenex partner to provide innovative Proxy Revenue Swap

The world’s first Proxy Revenue Swap is announced – securing long term revenues for Capital Power’s Bloom Wind Farm.

Allianz Risk Transfer (Bermuda) Limited (ART) and partners have developed an innovative risk management solution for hedging wind volume risks for wind farms. ART has executed a 10-year Proxy Revenue Swap with Capital Power’s Bloom Wind Farm, to be constructed near Dodge City, Kansas.

This new risk management tool for the wind power industry was created and commercialized through a partnership amongst ART, Nephila Capital Limited (Nephila), REsurety, Inc (REsurety) and Altenex, LLC (Altenex). The 10-year agreement will secure long-term predictable revenues and mitigate power generation volume uncertainty related to wind resources for the 178 MW Bloom Wind Farm.

“This new product line for the wind power industry will enable more efficient and cost-effective financing of wind generation projects,” said Karsten Berlage, Managing Director of ART. Due to the high upfront cost of modern utility-scale wind projects, it is important for investors in such projects to be able to secure long term stable revenues to underpin the investment.

Previously, traditional price-focused hedging solutions have been commonly used to try to address this, but this newly created Proxy Revenue Swap offers an entirely new form of revenue risk management for the wind power industry. Similar in concept to a tolling agreement or capacity payment, this novel structure swaps the floating revenues of a wind farm – those driven by the hourly wind resource and power prices – for a fixed annual payment. This transaction is the first in a robust pipeline of future wind financings and would also be feasible in other wind farm markets globally beyond the US.

The ART-led swap is unique in several aspects. “Recent advances in data availability for the US wind market as well as in risk assessment and modeling allowed this unprecedented scope of risk transfer within a single product, which is available for up to 10 years,” explained Berlage. “In contrast to more short-term and price-focused hedging approaches, for the first time price and wind volume risks of a wind farm have been managed at the tenor needed to support a project’s capital structure and balance sheet”, Berlage continues. “The result is a level of revenue certainty never before available to the wind industry.”

Each partner contributed highly specialized expertise to create this innovative swap solution. ART and Nephila leveraged their collective weather risk transfer expertise, risk capacity, underwriting sophistication and credit strength. REsurety has provided the specialized risk analyses relied upon for the structuring of the Proxy Revenue Swap and delivers ongoing services as the calculation agent for the transaction. Altenex supports the management of power price-linked risk as part of the Proxy Revenue Swap structure.

ART and Nephila have a long-standing partnership in the weather and catastrophe risk markets and have worked with REsurety since 2012 to develop risk transfer products for the wind power industry. More recently, through a partnership established between REsurety and Altenex in 2015, protection against low wind output has been expanded to include power price risk as well as generation volume-linked risk exposures.
