Day-Ahead Ancillary Services Market Clearing Prices for Capacity Archives

View historical annual reports for day-ahead ancillary services (AS) market clearing prices for capacity (MCPC) as measured by day and settlement interval. These reports, designed to assist data analysis, contain the complete data for each year.

The AS MCPC report contains the full 96 intervals for each day for MCPCNS (non-spinning reserve service), MCPCRD (regulation service down), MCPRU (regulation service up) and MCPCRS (responsive reserve service). If no entry is available for a day, you may assume that non-spin service was not procured for that day.
