California CCAs Amass 6,000 MW in Long-Term Contracts with New-Build Clean Energy Resources

Expanding CCA sector continues to fuel clean energy development, green jobs, and economic growth throughout the state

Concord, Calif. – The California Community Choice Association (CalCCA) announced today that Community Choice Aggregators (CCAs) in the state have to date signed long-term power purchase agreements (PPAs) for more than 6,000 megawatts (MW) with new-build clean energy resources.

The total includes almost 5,000 MW in executed renewable energy PPAs – an increase of 1,700 MW compared to a year ago – and more than 1,000 MW in battery energy storage contracts, a four-fold increase over last year. The increasing volumes reflect the important leadership position CCAs hold as the main drivers of new clean energy procurement in California.

“These new totals show that community choice energy providers are continuing to make great progress in securing the energy resources California needs to build a clean, affordable, and reliable electric system,” said CalCCA Executive Director Beth Vaughan. “At the same time, CCAs are driving economic recovery and job creation in the state when they are most needed.”

Each November for the last three years, CalCCA has provided a snapshot of the progress CCAs are making in securing new-build clean energy resources through long-term PPAs. This year’s update shows CCAs have added in a single year a record-setting amount of clean energy to their portfolios while bringing more diverse resources to the mix.

CCAs have signed in the last year renewable energy and energy storage PPAs totaling 2,600 MW, bringing the grand total to more than 6,000 MW in new-build solar, wind, biogas, energy storage, and, for the first time, geothermal energy. The geothermal power plant, slated for completion in 2021, will be the first new geothermal facility built in the California Independent System Operator balancing area in 30 years.

With record-breaking heat, rampant wildfires, and Public Safety Power Shutoffs (PSPS) threatening the stability of California’s power grid, energy storage is becoming an ever more important reliability resource. Aggregators are stepping up to ensure more storage is added to the grid with the signing of long-term battery energy storage contracts totaling 1,072 MW/3,847 megawatt-hours (MWh), quadruple the amount CCAs had at this time last year. About 72% of the total is co-located with solar generation facilities that will charge the batteries, allowing clean energy to be discharged at times of peak demand to boost reliability.

Seventeen CCAs have collectively signed 117 long-term PPAs with new solar, wind, biogas, geothermal, and energy storage facilities, up from 76 contracts in November 2019 – a 54% increase. The contract terms range from 10 to 25 years, or 17 years on average across all contracts. The clean energy resources are helping the CCAs meet their renewables portfolio standard (RPS) and long-term contracting requirements under SB 350, as well as local mandates set by CCA boards.

The 17 CCAs included in the PPA tally are Apple Valley Choice Energy, Central Coast Community Energy, Clean Power Alliance, CleanPowerSF, East Bay Community Energy, Lancaster Choice Energy, MCE, Peninsula Clean Energy, Pico Rivera Innovative Municipal Energy, Pioneer Community Energy, Rancho Mirage Energy Authority, Redwood Coast Energy Authority, San Jacinto Power, San Jose Clean Energy, Silicon Valley Clean Energy, Sonoma Clean Power, and Valley Clean Energy.

The clean energy projects are located in 21 California counties (up from 19 in 2019), from Humboldt County in the north to Riverside County in the south, as well as in the states of Arizona, New Mexico, and Nevada. Several projects are already operating, while others will become operational between 2020 and 2023. A map of project locations and a list of contracts can be found here.

With several new CCA requests for offers (RFOs) currently underway and planned, the list of CCA long-term clean energy contracts is set to grow considerably in the coming year. Notably, a group of CCAs recently issued a joint RFO for 500 MW of long duration storage (LDS) with a minimum of eight hours of discharge duration. CCAs are procuring LDS to aid in meeting California’s 2030 greenhouse gas reduction targets.

With a decade of successful operation in California, aggregators are viewed as reliable and stable counterparties and are proving adept at securing the cost-effective energy resources the state needs to meet ambitious climate action goals. Four CCAs – Central Coast Community Energy, MCE, Peninsula Clean Energy, and Silicon Valley Clean Energy – have investment-grade credit ratings, and more CCAs are expected to follow suit.

As of 2020, CCAs serve over 50 gigawatt-hours (GWh) of load, representing 28% of the load in the service areas of California’s three main investor-owned utilities (Pacific Gas & Electric, San Diego Gas & Electric, and Southern California Edison). Based on planned CCA launches over the next two years, CalCCA forecasts CCAs will serve 36% of IOU load in 2022.


About CalCCA: Launched in 2016, the California Community Choice Association (CalCCA) represents California’s community choice electricity providers before the state Legislature and at regulatory agencies, advocating for a level playing field and opposing policies that unfairly discriminate against CCAs and their customers. There are currently 23 operational CCA programs in California serving approximately 10 million customers.
