About this data
Each row is a snapshot of MISO's published ancillary-service clearing prices for one reserve zone and market run, collected from MISO's real-time data APIs about every minute. Prices are kept by zone and product, since MISO does not publish a market-wide figure. Use it to watch reserve prices as they move and to compare real-time with day-ahead.
