An energy trade association which includes Apple, energy storage maker AES and solar giants SunPower and First Solar in its leadership has welcomed the proposal by US energy regulator, FERC, to remove barriers to participation in wholesale markets for energy storage and distributed energy resources (DERs).
Advanced Energy Economy (AEE), which seeks to have an impact on policy matters shaping future energy concerns, was among the groups submitting lengthy documents to FERC, which was soliciting views until 13 February on its Notice of Proposed Rulemaking (NOPR).
The NOPR was issued in November last year and proposed to integrate electricity storage into organised markets, specifically the wholesale markets operated by the US’ Regional Transmission Organisations (RTOs) and Independent System Operators (ISOs), which between them ensure the reliability of the majority of the country’s electricity supplies.
In order to remove barriers to participation in these markets, RTOs and ISOs would be required to alter tariff structures in order to recognise specific characteristics of energy storage resources and give energy storage operators a new classification for their assets.
Critical first step
Acting chairwoman of FERC, Cheryl LaFleur, was widely quoted as saying the regulator had received “a lot of comments” in her appearance at the National Association of Regulatory Utility Commissioners (NARUC) earlier this week.
Advanced Energy Economy, which also includes Johnson Controls, Schneider Electric and GE in its leadership council, along with general members that include Amaresco, Alevo, Tesla, Sunverge and Younicos, from the world of energy storage along with diverse mainstream names such as Amazon and Facebook, was “strongly supportive” of the FERC NOPR, its comments said.
“The NOPR is a valuable and critical first step in what must be a comprehensive effort to eliminate unjust, unreasonable, and unduly discriminatory barriers to participation for advanced energy technologies in FERC-jurisdictional wholesale markets,” AEE said.
Currently, FERC, which should have a five-person executive board, is led by former utility executive LaFleur and just one other board member, Collette D Honorable, who is set to step down in summer as her five-year term ends. The NOPR cannot be acted upon definitively until the full board is completed, which requires nominations from the White House, followed by a vetting process and confirmation vote, which some sources said could take at least two months.
Battery-friendly PJM’s ‘supportive’ response
PJM Interconnection, which is noted in energy storage for being the first of the US RTOs to allow batteries to provide frequency response grid services in a competitive market, said it was “supportive” of the NOPR. PJM coordinates wholesale markets in 13 US states and the District of Columbia.
“…Electric storage resources (“ESRs”) have already flourished in a number of PJM markets, and through its stakeholder process, PJM is working to expand its market rules to allow for additional opportunities for ESRs and distributed energy resources,” PJM’s comment said.
Nonetheless there were two areas where PJM said it wanted to see changes in the NOPR before it passed into a new set of rules. The first was on “key threshold issues such as potential jurisdictional issues” which relate to charging and discharging of behind the meter resources, the second was that rules should be flexible enough to accommodate the sometimes subtle differences between each RTO/ISO.
