Ancillary Services Prices and Quantities
The ISO conducts day-ahead and hour-ahead auctions for four ancillary services: Regulation, Spinning Reserves, Non-Spinning Reserves, and Replacement Reserves. This page contains data on ancillary services prices and quantities for both the day-ahead and hour-ahead markets. Prior to June 1999, the data are only for the day-ahead market. The data files for June 1999 and afterwards contain data for the day-ahead and hour-ahead markets. The number of zones for which data are available is increasing with time.
