How It Works

Ava is the default electricity provider in Alameda County, unincorporated San Joaquin County, and the San Joaquin County cities of Tracy, Stockton, and Lathrop.

Ava is a Community Choice Aggregator, which is a not-for-profit local government agency that generates electricity for everyone in the community. The City Council or county supervisors vote to have their community join and have Ava as their electricity supplier. By law, customer enrollment is automatic.

Ava is on a path to provide 100% carbon-free electricity to all of our customers by 2030. Today, customers can choose from our Bright Choice service, which is 0.5% cheaper than PG&E rates, or our Renewable 100 service, which delivers 100% renewable electricity for 1¾ cents more per kilowatt-hour than PG&E rates. Ava’s service terms and conditions include an overview of these products, default options, fees, and more.

1. We generate clean power

We build and buy from clean power plants to supply our customers. If you’re not an Ava customer, PG&E generates your power instead.

2. PG&E delivers the power

Our power is delivered to customers by PG&E. Customers pay PG&E for power delivery as they always have.

3. You get the power and all the benefits

Customers benefit from clean energy, low rates, local governance, and innovative programs.

Local Benefits

Competitive Rates
Our Bright Choice plan is priced 0.5% below PG&E rates (including all fees) so customer bills are lower than what they would have been with PG&E generation service.

Stable Rates
We have long-term contracts for wind, solar, geothermal, and battery storage at low, stable rates and we pass those savings on to our customers.

Local Investments
We offer local energy programs to help customers adopt clean energy technologies. We also invest directly in the community through grants and sponsorships.

Our Environmental Impact

Night Heron

We buy power mainly from clean sources like wind, solar, and hydropower. We are contracted to build 2,452 MW of wind, solar, geothermal, and battery storage for our customers.

Our Board of Directors established the goal of purchasing 100% carbon-free power for all customers by 2030 — a full 15 years before the state’s goal date.

* PG&E data as reported for the Base Plan in PG&E’s 2025 Power Content Label.

** Biomass & biogas, geothermal, eligible hydroelectric, solar, and wind are renewable resources under California’s Renewables Portfolio Standard (RPS). Large hydroelectric and nuclear are not considered renewable, but are zero-carbon resources.

*** “Unspecified Power” refers to electricity that is not traceable to a specific generating facility, such as electricity purchased from a genericized pool on the open market. In 2025, 92% of unspecified power came from fossil fuels and 8% came from renewables and zero-carbon resources.
