On November 17, 2022, FERC issued three orders intended to address the reliability impacts of the rapid integration of inverter-based resources (“IBRs”), including solar, wind, fuel cell, and battery storage resources, on the Bulk-Power System (“BPS”). Specifically, in the first proceeding, FERC directed the North American Electric Reliability Corporation (“NERC”) to develop a plan to register the entities that own and operate IBRs so that NERC may monitor their compliance with NERC’s Reliability Standards. In the second proceeding, FERC issued a Notice of Proposed Rulemaking (“NOPR”) to direct NERC to develop new or modified Reliability Standards that address reliability gaps related to IBRs. Lastly, in the final proceeding, FERC approved revisions to two of NERC’s Reliability Standards.
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.”…
On July 28, 2022, FERC proposed changes to its Uniform System of Accounts (“USofA”) in response to the growth of non-hydro renewable generation such as wind, solar, and storage and to codify accounting for renewable energy credits (“RECs”). FERC’s Notice of Proposed Rulemaking (“NOPR”) follows a Notice of Inquiry issued in January 2021 seeking comment on the appropriate accounting treatment for certain renewable energy assets (see January 28, 2021 edition of the WER). Comments on the NOPR are due 45 days from its publication in the Federal Register.

On December 17, 2021, FERC affirmed a Public Utility Regulatory Policies Act of 1978 (“PURPA”) qualifying facility (“QF”) self-certification for the Shields Valley Solar Facility (“Shields Valley”), a hybrid solar and battery project relying on inverters to limit its net power production capacity. In doing so, FERC reiterated its finding in its Broadview Solar rehearing order that a QF owner can use MW net output at the point of interconnection, taking into account inverter losses and other components to produce electricity, in determining whether a facility meets the 80 MW statutory maximum for QF status. Commissioner James Danly wrote separately in dissent explaining his view that Shields Valley plainly exceeds the statutory capacity limit for a QF.

On November 30, 2021, FERC issued and order accepting a California Independent System Operator Corporation (“CAISO”) tariff filing designed to clarify its market rules for hybrid and co-located resources. CAISO proposed two areas of revisions: 1) enhancing market participation for hybrid and co-located resources; and 2) allowing for the use of multiple aggregate capability constraints by co-located resources at a single generating facility in CAISO. Commissioner James Danly wrote separately questioning whether hybrid resources should continue to be exempted from CAISO’s resource adequacy requirements, but agreed the revisions were just and reasonable. …

On October 26, 2021, FERC issued an order accepting a California Independent System Operator Corporation (“CAISO”) tariff filing designed to improve CAISO’s markets by optimizing the performance of storage and demand response resources. CAISO proposed three distinct tariff revisions: (1) creating biddable state of charge parameters for energy storage; (2) applying market power mitigation to energy storage; and (3) enabling demand response resources to specify maximum daily run times.

On March 19, 2021, FERC set aside a September 1, 2020 order (“September Order”) that had upended 40 years’ worth of FERC precedent regarding how to determine the 80MW threshold for small power production qualifying facilities (“QFs”) under the Public Utility Regulatory Policies Act of 1978 (“PURPA”). Specifically, FERC rejected the September Order’s denial of QF status to a hybrid photovoltaic solar and storage facility owned by Broadview Solar LLC (“Broadview”) as a result of the facility’s 160 MW gross capacity, as opposed to the facility’s 80 MW maximum net output or “send out.” After further consideration, FERC explained that it had erred by departing from and overturning its longstanding “send out” precedent. Commissioner Danly dissented, arguing that the September Order correctly applied PURPA in relying on gross power production capacity.

On March 18, 2021, FERC issued Order No. 2222-A, setting aside its finding in Order No. 2222 that demand response resource participation in heterogeneous distributed energy resource (“DER”) aggregations are subject to the opt-out and opt-in requirements of Order Nos. 719 and 719-A, as well as clarifying other requirements in Order No. 2222 concerning Qualifying Facility (“QF”) interconnection policies, restrictions to avoid double-counting services, and information sharing and criteria for the distribution utility review process. Concurrent with Order No. 2222-A, FERC also issued a Notice of Inquiry (“NOI”) seeking comment on whether to revise its more than a decade-old regulations requiring Regional Transmission Organizations and Independent System Operators (“RTO/ISO”) not to accept bids from an aggregator of retail customers (“ARC”) where the relevant electric retail regulatory authority (“RERRA”) prohibits such customers’ demand response resources from being bid into organized markets (“Demand Response Opt-Out”). Specifically, the NOI applies only to regulations where an ARC aggregates the demand response of the customers of utilities that distributed more than four million megawatt-hours in the previous fiscal year and is intended to examine whether changing circumstances warrant revision of the Demand Response Opt-Out and whether the RTO/ISO market would benefit from including currently barred Demand Response Opt-Out resources.

On January 19, 2021, FERC directed Regional Transmission Organizations (“RTOs”) and Independent System Operators (“ISOs”) to submit informational reports regarding four hybrid resources issues: (1) terminology; (2) interconnection; (3) market participation; and (4) capacity valuation. Specifically, FERC directed that each RTO or ISO file a report within 180 days from the order providing: (1) a description of its current practices related to these four issues; (2) an update on the status of any ongoing efforts to develop reforms related to the four issues; and (3) responses to the specific requests for information contained in the January 19, 2021 order. FERC’s request for reports follows a technical conference focusing on technical and market issues raised by hybrid resources (see April 14, 2020 edition of the WER) and a Notice Inviting Post-Technical Conference Comments.

On October 15, 2020, FERC issued an order sustaining, with modifications, its previous denial of a complaint that claimed New York Independent System Operator, Inc.’s (“NYISO”) buyer-side market (“BSM”) power mitigation rules were unjust, unreasonable and unduly discriminatory. FERC upheld its previous determination that the application of BSM rules to electric storage resources (“ESRs”) does not inappropriately interfere with state policies and that the complainants failed to show that NYISO’s existing rate was unjust and unreasonable because it over-mitigates electric storage resources. FERC’s order sparked a dissent from Commissioner Glick who argued that the majority’s order was arbitrary and capricious, and that BSM power mitigation should only apply to buyers with market power.
