Renewable energy & storage

Other energy sources

To address customer affordability objectives, PG&E updated our 2030 target to 75% greenhouse gas-free electricity, which is consistent with California’s 60% Renewables Portfolio Standard (RPS) clean electricity requirement; the prior target was 70% RPS. PG&E remains committed to 90% greenhouse gas-free electricity in 2035 and 95% greenhouse gas-free electricity in 2040.

Our approach

PG&E is working to ensure that California’s sustainable energy future is both reliable and clean, and we have a strong conviction that we can do both.

The dynamics of California’s energy landscape continue to evolve with growing demand, retail customer choice, advancing energy storage technologies, changing use of conventional power plants, and the growth of DERs, including rooftop solar and battery storage. Utility-scale renewable energy also continues to grow. We are managing this transition by optimizing our existing portfolio and adding more renewable energy and energy storage to our power portfolio.

As we endeavor to build a smarter grid, PG&E will continue to gain greater visibility to improve operational performance and more effectively integrate renewable energy onto the grid.

More battery power to integrate renewable energy

There are times during the middle of the day when California’s renewable resources can generate more electricity than customers can use. Battery energy storage allows PG&E and other utilities to store excess solar or wind power for later use.

PG&E operates 183 MW of utility-owned battery storage and has contracts for more than 4.6 GW of battery energy storage capacity being deployed throughout California over the next several years. Of that, more than 2.4 GW was connected to PG&E’s electric grid at the end of 2024, including several facilities commissioned during the year:

230 MW Sunlight Energy Storage II (Riverside County)
100 MW Beaumont Energy Storage (Riverside County)
50 MW Poblano Energy Storage (San Bernardino County)
38 MW Geysers Power Company Storage (Lake County)
80 MW Canyon Country ESS I, LLC (Los Angeles County)

Measuring progress

In 2024, PG&E supplied 98% greenhouse gas-free electricity to residential and business customers to whom we directly sell power, with 23% coming from RPS-eligible sources, including solar, wind, small hydroelectric, geothermal, and various forms of biopower. PG&E retail customers also received 63% of their electric deliveries from carbon-free nuclear power generated by Diablo Canyon Power Plant, and 12% from large hydroelectric power.

The chart below shows PG&E’s overall electricity supply mix for 2024, which includes the electricity PG&E generated and procured as a percent of retail sales.

^1. Eligible renewable resources include geothermal facilities, hydroelectric facilities with a capacity rating of 30 MW or less, biomass and biogas, selected municipal solid waste facilities, photovoltaic, solar thermal, wind facilities, ocean thermal, tidal current, and wave energy generation technologies. Due to rounding, these figures may not add up to 23%; additionally, data are preliminary and will not be finalized until verified by the CEC.

Our electricity mix will likely change significantly in future years due to Diablo Canyon Power Plant’s generation being allocated to all California utilities, which began for Unit 1 in 2024 and both Units 1 and 2 in 2025. Additionally, we are likely to see changes stemming from strategies to manage customer affordability, including the sale and allocation of our RPS portfolio to departed customer load and other RPS product sales, resulting in the use of our banked RPS credits.

Highlight

The majority of PG&E’s renewable energy comes from contracts with third-party developers. In 2024, PG&E’s RPS-eligible portfolio included more than 250 contracts for over 6,000 MW of renewable energy capacity. PG&E also has 44 utility-owned RPS-eligible generation facilities representing over 400 MW of additional capacity.
