Ahead of the February 28, 2025 launch of the new Day-Ahead Ancillary Services, ISO New England is providing sample values of the Day-Ahead Ancillary Services Strike Prices and Expected Close-Out Components based on actual market and system conditions during several days before the go-live date.
Once the market goes into effect, the Strike Prices and Expected Close-Out Component values will be published daily, starting on February 28, 2025. The Strike Price and Expected Close-Out Component will be available by 5:30 A.M. in eMarket in the Strike Prices screen available under the Public tab. They will be published at 10:30 A.M. to ISO Express. The values published to ISO Express will reflect the analysis and updates performed by the Internal Market Monitor. While the Expected Close-Out Component and the Expected RT Hub LMP may change, the Strike Prices are not updated for a given Operating Day once they are first published to eMarket.
The sample Strike Price and Expected Close-Out Components for each hour of Operating Day 2/25/2025 are seen in the table below.
