Demand Response

The Independent Electricity System Operator (IESO) is engaged in a number of demand response initiatives which include both reliability and real-time price demand response programs.

The Emergency Load Reduction (ELRP) is a real-time price based program intended to build the Ontario market's demand response capability and infrastructure. The Emergency Demand Response Program (EDRP) is a reliability-based program intended to mitigate the adverse impact of shortages of energy under stressed system conditions.

The Demand Response 3 (DR 3) program was developed by the Ontario Power Authority (OPA) to provide economic incentives for participants to reduce consumption. This is a contract-based program, with DR 3 participants required to reduce load when called upon.
