FERC, in response to AEU’s request for reh’g, modifies and sets aside, in part, the Order 2222 60-Day Compliance Filing Order.  ISO-NE directed to submit a further compliance filing on or before Jul 22, 2024, to include submetering requirements for DERAs participating as submetered Alternative Technology Regulation Resources (ATRRs) in the Tariff, rather than in OP-18.  The FERC set aside its finding that ISO-NE’s application of its existing requirements for ATRR to DERAs seeking to provide regulation service is consistent with Order 2222, stating that it will assess whether ISO-NE has satisfied this requirement with respect to sub-metering requirements for ATRRs after ISO-NE submits the further compliance filing.
