The New Capacity Show of Interest (SOI) Form submittal window for the 2025 interim reconfiguration auction (RA) qualification process is open and will close on April 30, 2025 at 23:59. These SOI Forms must be submitted via the Forward Capacity Tracking System. Materials detailing the SOI Form requirements and submission process for the 2025 interim RA qualification process can be found on the Forward Capacity Market Participation Guide webpage.
As further explained below, the ISO is seeking narrowly tailored Tariff changes to allow the performance of a Transitional Capacity Network Resource Group Study (TCNRGS) with the 2025 interim RA qualification process. Project Sponsors seeking to have a project complete the TCNRGS must submit an SOI Form for, and complete, the 2025 interim RA qualification process. Project Sponsors can withdraw a project from the TCNRGS by withdrawing the project from the 2025 interim RA qualification process by the October 23, 2025 capacity withdrawal deadline.
For further background, on May 14, 2024, the ISO, the New England Power Pool (NEPOOL) Participants Committee, and the Participating Transmission Owners Administrative Committee (PTO AC) on behalf of the New England Participating Transmission Owners (collectively, Filing Parties), submitted revisions to ISO New England’s Transmission, Markets and Services Tariff in compliance with, and related to, Order Nos. 2023 and 2023-A (together, the Compliance Proposal). On April 4, 2025, FERC issued an order accepting the Compliance Proposal in part and directed the Filing Parties to submit a further compliance filing within 60 days of the order.
The April 4, 2025, order accepts the main components of the Compliance Proposal, including the major deviations from the FERC pro forma rules proposed under the independent entity variation (including use of a TCNRGS as part of the transition activities). Notably, the order did not modify the June 13, 2024, eligibility date set by Order No. 2023 and affirmed in Order No. 2023-A, and accepts all dates proposed in the Compliance Proposal, including the August 12, 2024 effective date.
In response to the order, one step that the ISO is taking is to adjust the dates necessary to shift the transition activities in the Compliance Proposal by approximately one year (including the TCNGRS). This step will allow the TCNRGS to take place with the 2025 interim RA qualification process. The proposed Tariff revisions to adjust the dates need to be filed promptly with FERC to have clear rules for running the TCNRGS with the 2025 interim RA qualification process. The ISO plans to file the narrowly tailored date changes under Section 205 of the Federal Power Act immediately following the May 2025 NEPOOL Participants Committee meeting and request a next-day effective date for the revisions to adjust the dates.
