Serving San Mateo County since 2016

Under the Community Choice Aggregation (CCA) program, San Mateo County and all 20 of its cities and towns voted unanimously to form Peninsula Clean Energy, a community-controlled, not-for-profit, joint powers agency. As a CCA, Peninsula Clean Energy offers many environmental and economic benefits to its residential and business customers:

Peninsula Clean Energy provides the local community with more control over their electricity supply

Choosing clean, renewable electricity (such as solar, wind and geothermal) reduces the consumption of fossil fuels, leading to lower greenhouse gas (GHG) emissions

Earnings are reinvested in the community in the form of new energy projects and programs that further reduce greenhouse gas emissions

Who we are

Peninsula Clean Energy is the community-led electricity provider for San Mateo County and, beginning in 2022, for the City of Los Banos. We provide clean electricity at lower prices than PG&E and invest proceeds back into the community.

As one of California’s Community Choice Aggregation (CCA) organizations, Peninsula Clean Energy has the flexibility and local control to use innovative options in purchasing and generating electricity for residents and businesses.

Peninsula Clean Energy’s goals include continuing to provide energy that is 100% carbon-free and that will be 100% renewable by 2025.

Our strategic goals

Design a diverse power portfolio that is greenhouse gas free.


100% greenhouse gas free


100% California Renewable Portfolio Standard (RPS) renewable


Create a minimum of 20 Megawatts (MWs) of new local power

Clean energy at low rates

Peninsula Clean Energy is now serving all of San Mateo County with cleaner energy at low rates.

As a Peninsula Clean Energy customer, you have a choice in the amount of electricity that comes from renewable energy with our two different product options. You can choose our default option, ECOplus, with lower rates and nearly double the percentage of renewable energy as that of PG&E. If you can afford to pay a little extra and want to help even more to reduce greenhouse gas emissions, you can choose ECO100, our 100% renewable product. When you choose 100% renewable energy,  you’re leading the charge for a more sustainable future for San Mateo County.
