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 estimate project-specific carbon impact of solar, wind and energy storage – a first for the industry

BOSTON–(BUSINESS WIRE)–#CO2–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.

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. The new Locational Marginal Emissions 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.

“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.”

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 hear more about why leading companies are adopting this new tool, see their statements in the full release here.
