BOSTON, Mass. – October 15, 2024 – REsurety, Inc., a mission-driven organization dedicated to accelerating the world’s transition to a zero-carbon future, today announced the launch of its first-of-its-kind, scalable transaction marketplace to empower and accelerate the clean energy transition: CleanTrade. The new marketplace has been funded by the company’s recent Series C raise, led by S2G Ventures (“S2G”), a multi-stage investment firm focused on venture and growth-stage businesses across energy, food, agriculture and oceans, and Citi with participation from Angeleno Group and existing investors. 

Until now, clean energy did not have access to a scalable trading platform or marketplace. As a result, clean energy procurement, trading and risk management have remained opaque, slow and inefficient – both financially and environmentally. The CleanTrade marketplace is a platform for buyers, sellers and traders to provide price transparency and facilitate end-to-end transaction workflows for financially settled contracts for clean energy, or virtual power purchase agreements (VPPAs). Contingent upon approval by the Commodity Futures Trading Commission (CFTC), CleanTrade will provide the first CFTC-compliant marketplace for clean energy, known as a Swap Execution Facility (SEF), and in doing so will empower clean energy markets with price transparency and liquidity as well as end-to-end workflows of structured negotiation, on-platform execution and compliance reporting. It is the only existing platform that allows users to rank trades in terms of what is most and least attractive by the implied cost of the carbon abated, supporting a continued commitment to operationalize the Emissions First Partnership’s principles. In addition to this newly created SEF, CleanTrade supports physical power purchase agreements (PPAs) and project-specific renewable energy certificates (RECs).

“CleanTrade fills a critical gap in the energy transition’s toolkit, providing the level of price transparency and transaction liquidity that traditional energy has long benefited from but which clean energy markets have sorely lacked,” said Lee Taylor, REsurety’s founder and CEO. “REsurety has a long history of empowering great decisions with data and insights – and with this new offering we now make those decisions actionable at scale. We are grateful for the support of our new investors and partners at S2G and Citi and look forward to continued collaborative success.”

CleanTrade complements REsurety’s existing software platform, CleanSight, an industry leader for insight into clean energy assets and contract performance. CleanSight offers an integrated suite of clean energy software solutions, enhanced by support from REsurety’s deep domain experts, that buyers, sellers and investors have long trusted to identify opportunities and risks, evaluate projects and manage their operational portfolios. Both platforms share the same goal of empowering customers to confidently deploy capital to the highest impact opportunities in the market through transparency, liquidity and impact.

“At S2G, we are committed to supporting innovations that can help accelerate the clean energy transition, and we believe REsurety and its CleanTrade marketplace represent a game-changing platform in this regard,” said Francis O’Sullivan, managing director at S2G. “Our view is that by providing enhanced price transparency and liquidity, CleanTrade can help reduce the barriers to customer adoption of clean electricity and in turn, this will help support further deployments of clean electricity production capacity.”

O’Sullivan has joined REsurety’s board of directors.

The development of CleanTrade’s innovative digital platform initially grew from Citi’s Commodities division in Markets. CleanTrade is a great demonstration of Citi’s innovation strategy to identify market problems and develop solutions that drive market opportunity and serve clients.

“With REsurety and Citi’s long-standing partnership, it was a natural fit for REsurety to take this on, further develop the platform, and provide the clean-energy economy with a robust diverse product offering,” said Siris Singh, global head of markets strategic investments at Citi.

Renewable energy certificates (RECs) play a crucial role in steering investments toward renewable energy sources like solar, wind, and hydro. However, despite their importance, the current REC market often lacks transparency regarding the actual emissions impact of these certificates. Buyers aiming to reduce their carbon footprint may not fully understand the real-world impact of their REC purchases, leading to inefficiencies in pricing and market adoption.

This webinar, hosted by S&P Global Commodity Insights and REsurety shed light on the current dynamics of the REC market. We introduced the concept of Emissions Adjusted RECs and discussed how integrating emissions data can revolutionize REC markets, enabling more accurate and impactful trading opportunities.

Key Takeaways

  • Understanding the current REC market and its challenges.
  • Introduction to Emissions Adjusted RECs and their benefits.
  • Insights into the future of renewable energy trading.

Paper: Validating Locational Marginal Emissions Models with Wind Generation

This paper, authored by Nat Steinsultz, Pierre Christian, Joel Cofield, Gavin McCormick, and Sarah Sofia was published by IOP Science in Environmental Research: Energy, Volume 1. You can find the full paper here, or download a PDF version by clicking the button below.

Paper: Validating Locational Marginal Emissions Models with Wind Generation

Abstract

Increasingly large amounts of electric supply and load are being deliberately operated or sited on the basis of marginal emissions factor (MEF) models. Validating and calibrating such models is therefore of growing policy importance. This paper uses a natural experiment involving variation in relative changes in wind generation potential at wind farms in the ERCOT power grid to create a benchmark MEF and examine the relative accuracy of several common classes of short term MEF models. This work focuses on MEFs at the level of a few individual generating nodes, a much smaller geographic scale than the Balancing Authority (BA) or load zone. Additionally, the use of wind generation potential as a regressor allows us to factor in wind curtailment, in contrast to previous work. We evaluate multiple prevalent existing MEF models and find that both dispatch and statistical MEF models have a high degree of agreement with the benchmark MEF, while heat rate and average emissions do not. We also find that the emissions reduction benefits of optimizing electricity with MEFs using a geographically granular model instead of a BA-wide model are 1.4, 1.3 and 1.5 times larger for dispatch, statistical and heat rate models, respectively.

Deliverability: Can Clean Energy Reach Consumers?

Clean energy generators are the fastest growing sources of new energy on grids across the country. But if the impact of those new projects is going to be maximized, and utilized meaningfully in hourly matching carbon offset techniques, the country also needs to invest large sums in improving transmission infrastructure to get the clean energy to load centers. There have been a couple of recent announcements aiming to speed up the development of much-needed transmission (e.g. FERC Order 1920 and Department of Energy TSED funding), but how much of a problem is transmission currently?

To answer this question, we’ll use the concept of “deliverability” – in other words, how much clean energy can reach consumers in a given location. The concept of deliverability is already built into the market prices that system operators publish. There are three components to Locational Marginal Prices (LMPs); energy, congestion, and line losses. Line losses tend to contribute relatively little to the overall prices, and so we can use the difference in LMPs between two locations to estimate the deliverability of the energy. When the LMP at a generator diverges materially from the LMP at the load center, this is a sign that the location is experiencing congestion – either high prices that encourage generation, or low (even negative) prices resulting in renewable generator curtailment.

For this analysis, we’ve defined power as “deliverable” if the LMP at the generator is within 10% of the LMP at the load center. Renewable generation output during periods with greater than 10% LMP divergence is likely subject to congestion, and is therefore considered undeliverable. This is a somewhat simple metric, but it aims to boil down a complex issue into something digestible and relevant; after all, deliverability is a key component in the developing hourly matching frameworks.

In Figure 1, the 12-month trailing average of deliverability is shown for clean energy generators in ERCOT and PJM and load centers in Houston and Chicago, respectively. Historically, only between half and two-thirds of clean power is “deliverable” to these major load centers. This highlights that transmission congestion has been, and still is, a meaningful issue. It’s also notable that despite higher penetration levels of wind and solar in ERCOT, the deliverability of clean energy to Chicago has dropped more rapidly since the start of 2021.

Figure 1: Trailing 12-month average clean energy deliverability to Houston and Chicago.
Figure 1: Trailing 12-month average clean energy deliverability to Houston and Chicago.

When we look a little deeper at the ERCOT deliverability, separating the results for wind and solar projects, the story of the flatter deliverability trend becomes clearer. The deliverability of wind in ERCOT has been trending downwards over the past few years, while solar has trended upwards. There are two factors in favor of solar’s better deliverability: timing and location. Solar’s on-peak generation coincides with higher load, leading to fewer congestion issues. Furthermore, the operational solar fleet is more geographically dispersed compared to the wind fleet, meaning fewer solar projects are subject to major transmission constraints (such as in the Texas Panhandle and Gulf Coast).

Table 1: Deliverability of ERCOT wind and solar energy to Houston.
Table 1: Deliverability of ERCOT wind and solar energy to Houston.

Of course, these trends will evolve over time as more clean energy is added to the grid, thermal generators are decommissioned, energy storage capacity expands, gross and net load profiles evolve, and transmission either stays constant or gets upgraded. This metric is just the beginning of our efforts to analyze this complex issue. A REsurety whitepaper on deliverability is in the works, covering more regions and diving deeper into the underlying causes and resulting carbon impacts.

As part of the REsurety software platform, Portfolio Tracker was designed specifically for clean energy buyers and investors to forecast, audit, and explain the financial and environmental outcomes of clean energy projects and contracts. It was developed to analyze how wind and solar contracts are performing and what risks they hold; predict how settlement might occur going forward; and to track project and contract-specific carbon emissions and financial performance.

With today’s release of a new budgeting dashboard, customers can easily access forecasted settlement metrics for their contracts, including forecasts for the next month, quarter, the remainder of the current year, and for the following year. Long-term financial settlement forecasts, and forecasts for generation (and associated REC production), are available in the tool as well. Importantly, all of REsurety’s forecasts are Weather-Smart – meaning they take into account the wide range of future weather conditions that can have an immense impact on the price of power. Moreover, Portfolio Tracker automatically accounts for contract terms such as price floors, for example, applying them at the hourly level and aggregating settlement calculations to produce forecasts that are specific to individual renewable energy projects and contracts.*

Portfolio Tracker Budgeting Tab

The budgeting dashboard was designed with our customers’ renewable energy portfolio budgeting workflows foremost in mind and we are excited to help our customers hit their financial and sustainability goals with confidence. Get in touch to learn more about Portfolio Tracker.

Policy Brief: Assessing the Impact of Voluntary Actions on the Grid

A Consensus Paper from ZEROgrid’s Impact Advisory Initiative, published by RMI and ZEROgrid

Assessing the Impact of Voluntary Actions on the Grid

Executive Summary

Over the past 10 years, voluntary procurement of clean energy by corporations has been a tremendous driver of renewable energy development. Since 2014, large companies have signed procurement contracts supporting the development of over 70 gigawatts of renewable energy in the United States,1 in addition to purchasing renewable energy certificates (RECs), providing tax equity financing, and advocating regionally and nationally for more clean energy deployment. These voluntary procurement trends are continuing to scale and expand into other markets such as Japan, South Korea, and Taiwan.2

The urgency of the climate crisis is prompting many large energy consumers to consider how they can assess the impact of various actions on grid decarbonization and reliability. Such an assessment can be best made using consequential emissions impact analysis, which employs various approaches to estimate the difference between total global emissions in different possible states of the world.

Although many authors have published on consequential emissions impact analysis, there have been different views and until now no joint statement from differing authors on areas of consensus and how to resolve discrepant conclusions.

To provide greater clarity to corporate actors, ZEROgrid created the Impact Advisory Initiative, or IAI. The IAI comprises a group of expert practitioners from the National Renewable Energy Laboratory (NREL), Princeton University, REsurety, RMI, and WattTime who collectively identified key points of consensus as well as areas requiring further research.i

This paper provides an overview of the IAI’s findings regarding emerging areas of consensus about consequential emissions impact analysis, its implications, and areas where further research is required.

Areas of Consensus:

  1. Defining Impact. The true impact of any voluntary corporate action (or any action) is the difference in total emissions between a world where the action was taken versus one in which it was not taken.
  2. Components of impact. This impact is the sum of several different contributing effects, which must include the effects over the lifetime of the intervention — how an intervention changes the short-run operations of power plants, and structural change, i.e., how it changes the total supply of different power plants in the long run — to fully capture the impact of an action.
  3. Estimates versus true values. The field has a number of ways to produce estimates of total emissions impact and its components. Although there is agreement regarding how changes to short-run operations can be quantified, the field currently lacks — and indeed may always lack — any generally accepted way to empirically verify estimates of structural change. Therefore, any approach that seeks to measure total impact has (potentially significant levels of) uncertainty.

i The ZEROgrid initiative brings together a group of corporate actors, including Akamai, General Motors, HASI, Meta, Prologis, Salesforce, and Walmart, seeking to drive deep decarbonization alongside increased power grid reliability and affordability, working in collaboration with emissions and reliability experts.

Record-Breaking Winter for Solar: Behind The Scenes

Solar output in ERCOT has been in the news as of late, with the buzz around the record-breaking 17.2 GW peak on February 19th amplified by the 18.7 GW peak on March 28th. While impressive, these records are actually not broken as often, or by as much, as one might initially expect given the amount of recent solar buildout. The current generation record would be 300 MW higher were it not for the complex interactions between the weather, transmission infrastructure, and tax incentives.

First, and perhaps most obviously, the weather impacts renewable generation and demand, and when there’s too much of the former and not enough of the latter, renewable projects are curtailed. Net load (total load minus renewable generation) is a useful metric to highlight this behavior. Figure 1 shows solar curtailment as a function of net load for Q1 2024. It’s clear that as net load drops below 20 GW, solar generation starts to be curtailed, increasing quickly as net load reduces further. These grid-wide supply and demand balancing issues that lead to renewable energy curtailment also play out on a local level, caused by transmission constraints. Even if there’s enough demand overall on the grid, if the renewable energy is located behind a transmission constraint, curtailment will still happen. Finally, there’s the tax incentives – wind projects tend to receive the Production Tax Credit (PTC) while solar projects tend to receive the Investment Tax Credit (ITC). Since the PTC is earned on a per megawatt-hour basis, many wind projects continue generating even when wholesale prices are negative. On the other hand, ITC-qualified solar projects will curtail as soon as wholesale prices become negative.

Figure 1: Net Load and Solar Curtailment, January – March 2024. Record-breaking periods shown in blue, missed records shown in green.

So, in terms of setting solar generation records, there needs to be an alignment of these variables – high solar generation potential, relatively low wind generation, relatively high load, and no meaningful transmission constraints. Figure 2 shows two days in February with different conditions and different outcomes. The first is February 19th, when there were favorable conditions and a new record was set – the skies were clear, wind output was low during the day, and net load stayed above 20 GW. A few days later on February 24th, conditions were not as favorable – skies were clear in the morning, but wind output was increasing and net load dropped below 20 GW. This meant solar projects were curtailed and while a new solar generation record 300 MW above the February 19th level could have been set, it was not.

Figure 2: Actual and Uncurtailed Solar and Wind on February 19th, 2024 (left) and February 24th, 2024 (right) Compared to Net Load (load minus actual wind and solar generation).

It’s also important to note the seasonality in these trends. The time of year makes these solar output records more unlikely – the first quarter of the year tends to be windy and load levels are on the low side too. As the summer approaches, wind generation will be lower on average and load will be higher. More solar projects will also likely be commissioned by then, so expect more records to be broken (and perhaps more frequently). Looking further forward, it will be interesting to see if some of the new solar projects elect for Production Tax Credits and therefore start to operate during periods of negative prices. If so, expect even more records to be set.

However, lost generation due to curtailment isn’t all doom and gloom. By definition, renewables make up a large proportion of the grid’s generation during periods of low net load and curtailment. For corporate buyers measuring their impact in emissionality terms, this means the ‘lost’ emissions impact due to curtailment is relatively small – most of that curtailed energy would have displaced other clean fuels (rather than fossil generators). This is especially true during periods of low net load, where high wind generation will keep marginal emissions rates low regardless of the level of solar curtailment. Figure 3 shows the average ERCOT Locational Marginal Emissions rate declining as renewable energy curtailments increase.

Figure 3: Daily Average ERCOT LME (kgCO2e / MWh) and Renewable Energy Curtailment in January, 2024.

As always with power markets, there’s a lot more going on behind the headlines of record breaking solar output.
