The
Day-Ahead Scheduling Reserve Market is a market-based mechanism to procure supplemental, 30-minute reserves on the PJM System. On a day-ahead basis, PJM operators need the ability to schedule sufficient
generation so that unanticipated system conditions can be dealt with to preserve reliability during the actual operating day.
PJM currently schedules for this supplemental, 30-minute reserve requirement, Day-Ahead Scheduling Reserve, in both the Day-Ahead Market and the Reliability Analysis. It compensates generators for providing this reserve with day-ahead and balancing
operating reserve credits.
The
Day-Ahead Scheduling Reserve Market is an offer-based market that will clear existing reserve requirements on a forward basis. The market is designed to create an explicit value for an additional reserve product in the PJM markets on a short-term basis. The market is intended to provide a pricing method and price signals that can encourage
generation and demand resources to provide day-ahead scheduling reserves, and to encourage new resources to be deployed that have the capability to provide such reserves.
