Valley Forge, Pa., April 2, 2012 — PJM Interconnection implemented changes April 1 in the way demand response resources are paid in PJM's Energy Market.
* Demand response resources dispatched by PJM will be paid the full locational marginal price (LMP) when it is cost effective, based on a net-benefits test.
* The net-benefits test determines the point at which the savings to the system from dispatching demand resources are greater than the cost of paying those resources the full LMP.
* All demand response participation in the Energy Market will be cleared in the Day-Ahead Market or through real-time dispatch by PJM to enable PJM to effectively maintain power balance.
* Demand resources must submit offers for a price and time in the way a generator does and must follow the price signal to be paid.
