On May 29, 2026, FERC approved revisions to the ISO New England, Inc.’s (ISO-NE) proposed market rules for the participation of Distributed Energy Resources (DERs) and to implement a one-time extension to the period in which resources are required to resume commercial operation following a forced outage. FERC held that the tariff revisions are just and reasonable because they address a gap in ISO-NE’s rules created during the Order No. 2023 compliance process wherein there was no longer a process for DERs to establish Network Resource Capability (NRC) and/or Capacity Network Resource Capability (CNRC), which are necessary to participate in ISO-NE’s markets, and because they balance needed resource flexibility while ensuring timely repair after an outage.
