Port of Oakland Delivers 84% Renewable and Zero-Carbon Power in 2025

November 3, 2026

Cleaner electricity helps advance zero-emission goals as power demand grows across the Seaport and OAK

Oakland, Calif. – November 3, 2026: The Port of Oakland announced that 84% of the electricity delivered by its publicly owned utility, Port Public Power, to Port tenants and facilities in 2025 came from renewable and zero-carbon sources. The Port’s Board of Commissioners approved the annual Power Source Disclosure Report and Power Content Label for submission to the California Energy Commission at its October 22 meeting.

The Port’s electricity supply also had less than half the greenhouse gas emissions intensity of the average California utility, supporting the Port’s efforts to reduce emissions as more operations transition to electric power.

Renewable energy exceeds state average

Renewable resources accounted for 61% of Port Public Power’s electricity supply in 2025, compared with a 46% average for California utilities. Geothermal energy was the largest renewable source, followed by solar, biomass and biogas, and eligible small hydroelectric power.

An additional 21% of the Port’s electricity came from large hydroelectric power, with other zero-carbon market purchases bringing the total share of renewable and zero-carbon electricity to 84%.

The Port’s electricity supply had a greenhouse gas intensity of 186 pounds of carbon dioxide equivalent per megawatt-hour, compared with 384 pounds for the average California utility.

Cleaner electricity supports Port electrification

As the Port works toward its zero-emission goals, cleaner electricity helps maximize the environmental benefits of replacing diesel-powered equipment and vehicles with electric alternatives. Electrification across the Seaport and Oakland San Francisco Bay Airport (OAK) can reduce local tailpipe emissions, while a cleaner electricity supply helps limit emissions associated with generating the power.

Port Public Power expects electricity demand on its system to grow four- to five-fold over the next five years as tenants electrify their operations. Total demand could reach as much as 100 megawatts.

“Every year, more of the Port runs on electricity, and our job is to make sure that electricity is clean, reliable and affordable,” said Andre Basler, Director of Utilities at the Port of Oakland. “Delivering 84% renewable and zero carbon power means that as our tenants electrify their trucks, equipment, and operations, they are moving onto one of the cleanest power supplies in California. We intend to keep that supply getting cleaner as demand grows.”

Investments prepare the power system for the future

The Port continues to modernize, expand and replace aging electrical infrastructure to improve reliability and support electrification and sustainable energy across Port properties.

In 2025, the Port’s Board approved a 20-year Energy Storage Service Agreement with Trolley Pass Project LLC, providing the Port with 4 megawatts of capacity at a battery energy storage facility in San Bernardino County. Energy storage can help the Port make better use of solar power, reduce reliance on market purchases and advance its transition to clean energy.

The Port’s efforts support California’s Senate Bill 100 goal of achieving 100% clean electricity by 2045. As a publicly owned utility and member of the Northern California Power Agency, Port Public Power works with other public power utilities across the region to secure reliable, affordable and sustainable electricity for the businesses it serves.
