Demand response can compete equally with generation in these markets.

In PJM’s Energy Market, end-use customers participate in demand response by reducing their electricity use either during an emergency event or when locational marginal prices (LMPs) are high on the PJM system.  End-use customers participate in demand response in PJM through members called curtailment service providers (CSPs), who act as agents for the customers. A list of PJM members who are CSPs is available.
