FERC Approves ISO-NE Day-Ahead Reserve Tariff
The Federal Energy Regulatory Commission approved ISO New England’s “day-ahead ancillary services initiative,” or DASI, an effort designed to bolster the grid operator’s ability to call on flexible resources to meet its operating needs.
As background, on October 31, 2023, pursuant to section 205 of the Federal Power Act (FPA), 1 ISO New England Inc. (ISO-NE) and the New England Power Pool Participants Committee (NEPOOL) (collectively, Filing Parties) filed revisions to section I.2.2 to Market Rule 1, and Appendix A to Market Rule 1 of its Transmission, Markets and Services Tariff to, inter alia, establish a jointly optimized Day-Ahead market for energy and ancillary services (DAM) and sunset the existing Forward Reserve Market (FRM) (jointly, Filing Parties’ proposals are referred to as the Day-Ahead Ancillary Service Initiative (DASI)). As discussed below, we accept the filing, effective March 1, 2025, as requested.
The plan will provide increased revenue to flexible resources including energy storage that can provide reserves to meet any unexpected real-time power supply needs.
