Distributed Energy Resources (DERs), like rooftop solar and battery storage, have the potential to generate significant social benefits by displacing pollution-emitting electricity generators. Accurately compensating DERs for this environmental and public health value, which some regulators and experts call the “E-Value,” is imperative for making the most out of DERs’ potential.
This report provides a new set of hourly E-Values for the whole United States, broken down into 19 subregions, using an open-source reduced-order dispatch model. The patterns uncovered by these estimates can help policymakers design economically efficient DER policies to reduce air pollution from electricity generators.
