More long-term power-purchase agreements are being signed by California community choice aggregators, with roughly 600 MW in contracts signed in June alone, according to the California Community Choice Association’s latest report, released July 22.

CCAs have signed contracts for “well over” 2,500 MW with new renewable-energy facilities in California, according to CalCCA. They have also signed contracts for 150 MW/600 MWh of battery storage projects in less than a year.

The aggregators’ procurement of battery energy storage “is proving to be a case study that demonstrates the capability of CCAs to rapidly procure the resources the state needs to meet and exceed clean energy goals, despite their newness and short credit histories,” CalCCA Executive Director Beth Vaughan said in the organization’s second-quarter newsletter.

Statewide, CCAs now serve roughly 25 percent of load—a number that is poised to grow as more community choice programs come on line in 2020.

Some of the notable 2019 power-purchase agreements CalCCA cites include East Bay Community Energy, which approved 250 MW in PPAs in June alone, and Clean Power Alliance, which approved 285 MW the same month. Three more contracts—a total of 112 MW of solar and 7.5 MW of battery storage—were approved by the EBCE board of directors on July 17 (see CEM No. 1548 [6.1]).These were signed with esVolta, Sunrun and the Clearway Energy Group.

Many organizations expect to secure additional long-term contracts in the coming months, with others anticipating to issue new requests for offers (see CEM No. 1547 [16]).

CalCCA expects aggregators to add more than 1,000 MW in new-build, long-term renewables contracts by year’s end.

CCAs are planning to make long-term investments in more than 10,000 MW of new clean-energy resources by 2030. This includes energy sources such as solar, wind, geothermal and energy storage. In contrast, investor-owned utilities and energy service providers plan to invest in approximately 1,000 MW of new resources combined, according to the California Public Utilities Commission’s integrated resource plan issued April 25.

Under this plan, CCAs will be responsible for about 90 percent of the energy procurement that will be needed by 2030 to meet the state’s SB 350 target (see CEM No. 1548 [15]).
