On March 1, 2023, FERC partially approved ISO New England’s (“ISO-NE”) proposed tariff revisions in compliance with Order No. 2222, which removed barriers to the participation of distributed energy resource (“DER”) aggregations in the capacity, energy, and ancillary services markets operated by Regional Transmission Organizations and Independent System Operators (“RTO/ISO”). In the order, FERC directed ISO-NE to revise its proposal regarding small utility opt-in requirements, capacity market participation, information and data requirements, and metering and telemetry system requirements. Commissioner Christie dissented from the order arguing that ISO-NE’s proposed metering and telemetry requirements for DER aggregations are reasonable and should be encouraging RTO/ISOs to adopt rigorous measurement and verification (“M&V”) measures, not undercutting them. Commissioner Danly concurred with a separate statement, expressing how this decision underscores his original concerns with Order No. 2222, namely that FERC is interfering in managing RTO activities that, in his view, should be under state jurisdiction. Commissioner Clements also concurred with a separate statement urging ISO-NE to make its proposal open to all DERs, such as behind-the-meter DERs.

D.C. Circuit Upholds FERC Interpretation of PURPA Size Limitation Based on “Send out” to Point of Interconnection
On February 14, 2023, the United States Court of Appeals for the District of Columbia Circuit (“D.C. Circuit”) upheld FERC’s March 2021 order granting Broadview Solar, LLC’s (“Broadview”) hybrid solar and battery project qualifying facility (“QF”) status (see March 25, 2021 edition of the WER) based on FERC’s interpretation of the Public Utility Regulatory Policies Act of 1978 (“PURPA”). Specifically, the D.C. Circuit determined, among other things, that FERC’s interpretation that a QF owner can use the MW net output at the point of interconnection in determining whether a facility meets the 80 MW statutory maximum for small power production facility QF status under PURPA was reasonable.…

FERC Finds PUHCA Exemptions Appropriate for Holding Company Ownership of Grid-Charging Storage Facilities Selling at Retail
On November 17, 2022, FERC granted a petition for declaratory order (“Petition”) filed by Ameresco, Inc. (“Ameresco”) and its subsidiaries (collectively with Ameresco, “the Ameresco Companies”) requesting exemption from certain “books and records” requirements under the Commission’s Public Utility Holding Company Act of 2005 (“PUHCA”) regulations because its ownership of certain grid-charged battery storage subsidiaries might otherwise have caused Ameresco to lose its automatic “books and records” exemption under PUHCA. FERC granted the Petition, notwithstanding the fact that some of the storage subsidiaries would not otherwise qualify for the non-traditional utility “books and records” exemption, because the “Ameresco Companies’ books, accounts, memoranda, and other records are not relevant to the jurisdictional rates of Ameresco Companies.”…

D.C. Circuit Court of Appeals Denies Transmission Developer Challenge to MISO Baseline Reliability Project Cost Allocation
On August 19, 2022, the U.S. Court of Appeals for the D.C. Circuit (“D.C. Circuit”) denied a Petition for Review from LS Power and two other organizations (“Petitioners”) challenging FERC’s rejection of an earlier-submitted complaint against the Midcontinent Independent System Operator, Inc.’s (“MISO”) method of allocating costs for certain transmission construction projects identified as Baseline Reliability Projects in MISO’s transmission planning process. As the D.C. Circuit determined, FERC’s rejection of the Petitioners’ complaint was not arbitrary and capricious, as the Petitioners had failed to demonstrate that MISO’s cost-allocation method was unjust and unreasonable.
