Up until now, it’s been impossible for clean energy companies to make informed clean energy procurement decisions across the country in a way that makes their budgets go as far as possible when it comes to reducing carbon emissions. As of today, REsurety’s platform changes all that with the availability of both Weather-Smart power price forecasts and Locational Marginal Emissions (LMEs) data that now cover all seven U.S. deregulated ISOs (CAISO, ERCOT, ISONE, MISO, NYISO, PJM, and SPP).

REsurety first launched its power price forecasts and Locational Marginal Emissions data in Texas’ ERCOT market in December of 2022. This renewables-rich market is important for many clean energy buyers, developers and investors, given the rapid rate of growth of wind, solar and storage projects across the state. Ever since then, our team of atmospheric scientists, renewable energy and power markets experts, and software engineers have worked tirelessly to bring our solutions into new markets, helping us reach today’s milestone: full coverage across all U.S. deregulated ISOs.

Locational Marginal Emissions data enables customers forecasting and measurement of the emissions impact of their clean energy purchases. Weather-Smart power price forecasts provides forward-looking views of power prices and wind and solar capture rates based on project-specific weather modeling across 40+ years of representative weather scenarios. Having both of these data sets available across all ISOs allows our customers to compare the cost-benefit of different clean energy project purchasing decisions on a nationwide scale, something that previously wasn’t possible.

Emissions-focused clean energy customers can now leverage the REsurety platform to optimize for: cost per MWh, cost per ton of carbon avoided, or 24/7 Carbon Free Energy. The platform was designed for the full spectrum of clean energy customers, from buyers who are running RFPs, to hydrogen developers maximizing the cost-effectiveness of their electrolyzer. Regardless of each customer’s specific priorities, REsurety is able to help buyers or their advisors, as well as their clean energy suppliers, identify the best projects to suit their needs using our off-the-shelf PPA Evaluator tool or a more bespoke advisory engagement.

Webinar Recording: Hot Grid Summer: Unpacking ERCOT’s Unusually Warm Summer of 2023

Posted on November 15, 2023 by REsurety - Blog, Event, Webinar

The summer of 2023 felt like an endless chain of heat waves in the U.S. but nowhere more so than in Texas, which experienced its second hottest summer on record. In this webinar, meteorologists Jennifer Newman and Jessica Tomaszewski discussed the meteorological drivers of the heat wave, the temperature and demand records that were set, and the impact the heat wave had on power prices. They discussed:

Causes of the heat wave
How heat waves impact demand and renewable energy production
How climate change might impact the frequency of heat waves
How you can take extreme events into account for price forecasts

The session was interactive and there was an extensive Q & A session after the presentation.

Webinar Recording: Unpacking ERCOT Solar Capture Rates in REsurety’s Weather-Smart Forecasts

Posted on September 28, 2023 by REsurety - Blog, Event, Webinar

REsurety’s Weather-Smart forecasts show sharply declining solar value in ERCOT. Average solar capture rates fall to around 75% by 2030 in our baseline forecast, with significant weather and fundamentals-driven variability about that average. In this webinar, we unpacked these results by evaluating progressively more sophisticated forecasting models. We showed that:

Accounting for recent trends, changes to system fundamentals, and weather variability reduce forecasted solar capture rates.
Weather uncertainty leads to a wide range of capture rate outcomes given the fundamentals.
Uncertainty in solar buildout leads to an even wider range of solar capture rate outcomes.

We also had 10-15 minutes of Q & A after the presentation.
