Day-Ahead Ancillary Services Market Clearing Prices for Capacity Archives

View zonal archived annual reports on day-ahead ancillary services (AS) market clearing prices for capacity (MCPC) as measured by day and hour. These reports, designed to assist data analysis, contain the complete data for each year; the current year's report is updated monthly. You may find historical reports in archives.

The AS MCPC report contains the full 24 hours 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, non-spin service was not procured for that day.
