Calif. aggregators set pace for US energy transition

S&P Global

But in California, where the electric grid powers the world’s fifth-largest economy with 80% renewable energy at times, calls are growing louder for the state to accelerate its current zero-carbon target date of 2045. And California’s fastest-growing retail power suppliers, local government-run community choice aggregators, or CCAs, are well ahead of the curve.

Central Coast Community Energy, California’s largest CCA by geography, and East Bay Community Energy in Alameda County both aim to establish 100% zero-carbon power portfolios by 2030. Peninsula Clean Energy in San Mateo County and San Francisco’s CleanPowerSF hope to reach that milestone as soon as 2025.

MCE Clean Energy, California’s first CCA, which started in Marin County in 2010 and has since spread into Napa, Solano and Contra Costa counties, says its default power mix will be 95% free of greenhouse gas emissions by 2022.

“We all know that the [California ISO] has said we’re going to have natural gas on the grid for a long time, but our role is to help accelerate and deploy those affordable resources such that they may not need to keep those [resources] on,” said J.R. Killigrew, director of communications and outreach at Central Coast Community Energy.
