Interest in microgrids is on the rise in the United States as over half of states explore ways to modernize the grid and promote distributed energy resources (DER), including innovative renewable energy, storage, and demand response technologies. However, microgrids are not defined by law or regulation in most states and are more complex than other types of DER because they involve both the generation and distribution of energy. This raises several policy questions, including who should pay for microgrid development and use and whether microgrid operators that technically distribute energy to retail customers should be classified as public utilities and subject to regulations ordinarily imposed on such entities. California is currently exploring the potential benefits of microgrids and the role of state regulation.
New Jersey advanced several of the Murphy administration’s clean energy goals during June 2019. Over the past month, the state released a draft of its revised Energy Master Plan (EMP), approved the Ocean Wind offshore wind project proposed by Ørsted, and released a detailed analysis on energy storage development in New Jersey.
Consolidated Edison Company of New York, Inc. (Con Edison) and Orange and Rockland Utilities, Inc. (O&R) issued a draft joint Request for Proposals (RFP) on May 31 to competitively procure scheduling and dispatch rights from new energy storage projects. Through this initial solicitation, Con Edison and O&R are targeting at least 300 megawatts (MW) and 10 MW, respectively, of new energy storage facilities to meet the in-service deadline of December 31, 2022, set by the New York Public Service Commission (NYPSC) in its December 2018 Order (Storage Order) establishing New York’s three gigawatt (GW) energy storage deployment goal.
Both utilities will accept bids only for new storage projects sized over five MW and connected to the transmission or distribution system that can directly participate in New York Independent System Operator (NYISO) markets and provide distribution benefits, if applicable. These front-of-meter systems must be able to discharge for at least four hours 100 to 350 times per year, have at least 85% roundtrip efficiency, and maintain 98% availability for dispatch each contract year.
A recent grid reliability report issued by staff members of the Offices of Electric Reliability and Enforcement within FERC evaluating the upcoming operating season underscored the changing generation resource mix in the United States and its implications for grid operations.
The May 16 Order on Rehearing affirms FERC’s jurisdictional authority, and refuses calls for state opt-outs.
The Federal Energy Regulatory Commission (FERC or Commission) issued Order No. 841 early last year, a final rule amending FERC’s regulations to facilitate participation of electric storage resources in the capacity, energy, and ancillary service markets operated by regional transmission organizations (RTOs) and independent system operators (ISOs). Several entities have since challenged key aspects of the final rule, urging the Commission on rehearing to reverse course or modify its approach on a number of issues. On May 16, the Commission issued Order No. 841-A, denying those requests for rehearing, thereby upholding the initial rulemaking while providing some additional clarification.
The Federal Energy Regulatory Commission (FERC or Commission) appears to be inching closer toward a resolution on grid operators’ proposals to facilitate electric storage participation in organized capacity, energy, and ancillary service markets. On April 1, FERC’s Office of Energy Market Regulation (Staff) directed each of the Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs) that submitted compliance filings in response to FERC’s Order No. 841 to submit additional information on the mechanics of their proposed energy storage market rules. Those latest actions by Staff break FERC’s recent silence on the grid operators’ proposals, which were submitted to the Commission over four months ago and which must be implemented as early as December 2019.
Although tailored to each ISO’s and RTO’s proposal, Staff’s requests were largely centered on the same general areas and directed the ISOs and RTOs to further explain how the mechanics of their proposed storage participation models meet compliance with Order No. 841. For example, among other things, Staff sought more information on how the ISOs and RTOs will:
As we reported in December 2018, to jumpstart the energy storage market as envisioned by Governor Andrew M. Cuomo, the New York Public Service Commission (NYPSC) issued an order establishing an aggressive 3 GW energy storage goal by 2030, with an interim target of 1.5 GW by 2025, and directing investor-owned electric utilities (IOUs) to engage in competitive procurements for energy storage. The IOUs will issue draft requests for proposals (RFPs) this summer following a stakeholder process that kicks off on March 29.
In response to state legislation enacted last year, the New Jersey Board of Public Utilities (BPU) is seeking comments concerning the state of and prognosis for energy storage development within the State of New Jersey. New Jersey enacted the Clean Energy Act on May 23, 2018. Among other things, the act requires the BPU, in consultation with the regional grid operator, PJM Interconnection, LLC, and other stakeholders, to conduct an energy storage analysis and submit a written report on energy storage to the governor and legislature by May 23, 2019.
Effective April 1, energy storage resources will have more options to participate in ISO New England’s (ISO-NE’s) markets, subject to new rules accommodating storage resources that were approved by the Federal Energy Regulatory Commission (FERC) on February 25. The new market rules reflect a first of their kind in ISO-NE, and are a product of ISO-NE’s work to build on existing rules initially designed for pumped storage hydroelectric resources.
The New Jersey Board of Public Utilities (BPU) recently released its first annual report on the development of offshore wind in New Jersey (the Report). The Report comes one year after Governor Phil Murphy released Executive Order No. 8, which directed the BPU and other agencies to implement the Offshore Wind Economic Development Act (OWEDA).
