Locational Marginal Emissions (LMEs) are calculated at each power system node in a manner very similar to the Locational Marginal Prices (LMPs) used to set wholesale electricity market prices. LMEs measure emissions by identifying the marginal generators: the generators that would have been producing energy but for the renewable injection to the grid at that location at that moment. LMEs data is available in the REsurety platform, learn more.
LMEs reflect the impact of transmission congestion on carbon emissions and can be used to support granular siting decisions as well as generation technology selection.
High time-granularity LMEs can accurately evaluate the carbon benefits of energy storage that charges when emissions intensities are low and discharges when emissions intensities are high.
LMEs support calculation of carbon abatement cost effectiveness metrics for candidate clean energy projects, enabling investors, consumers, and policymakers to maximize the carbon impact of their clean energy program dollars.
View hourly LME performance for a wind project in ERCOT by using the sweep chart to focus on a specific hour range.
Compare historical carbon abatement levels for solar projects in CAISO.
Learn how Akamai uses LMEs to calculate avoided emissions more accurately, understand why their emissions are what they are, and to evaluate new PPA opportunities.
Read how Broad Reach Power, a leader in the energy storage space, uses LMEs to measure and communicate the carbon emissions impact of energy storage.
The carbon emissions avoided by a given MWh of clean energy varies widely, even across projects located within the same region in the grid. LMEs provides hourly visibility into the projects and activities that maximize your path to decarbonization, and those that don’t.
