Demand response (DR) is a grid flexibility mechanism where end-users adjust their electricity consumption based on automated triggers or price signals. Regulations like FERC Order 2222 in the US and EU Directive 2019/944 govern how DR programmes operate. Unlike Energy Attribute Certificates (EACs) that represent renewable generation, but DR is about load curtailment, you're reducing what you actually consume rather than certifying how it was produced. DR brings down your gross consumption, while EACs zero out emissions on whatever load remains under frameworks like the Greenhouse Gas Protocol. They address different sides of the same problem.
