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. This page contains data on hourly unconstrained market clearing prices and quantities.  After congestion management is performed, the PX issues final day-ahead schedules and calculates zonal market-clearing prices.
