The PX Day-Ahead market establishes prices and quantity of electricity for delivery during each hour of the following day. At 7 a.m. each day, 24 hourly auctions are conducted to produce unconstrained market clearing prices and quantities. After congestion management is performed, the PX issues final day-ahead schedules and calculates zonal market-clearing prices. This page contains data on hourly zonal (constrained) market clearing prices.
