Port of Oakland Reaches 84% Renewable and Zero-Carbon Energy in 2025
Cubierto por 2 fuentesPublicado
The Port of Oakland announced that 84% of the electricity supplied by its public utility, Port Public Power, to port tenants and facilities in 2025 came from renewable and zero-carbon-emission sources. The Board of Port Commissioners approved the Annual Power Source Disclosure Report and Power Content Label for submission to the California Energy Commission at its October 22 meeting.
Above the state average
According to the report, renewable energy accounted for 61% of Port Public Power's electricity supply in 2025, compared to a 46% average for California utilities. Geothermal energy was the leading renewable source, followed by solar, biomass and biogas, and small-scale hydroelectric power. An additional 21% of the electricity came from large hydroelectric facilities, which, combined with other zero-carbon-emission power purchases, brought the total to 84%.
Lower emissions intensity
The port's electricity supply had a greenhouse gas intensity of 186 pounds of carbon dioxide equivalent per megawatt-hour, compared to 384 pounds for the average California utility—less than half. This supports the port's efforts to reduce emissions as more operations become electrified.
Growing demand and electrification
Port Public Power expects electricity demand on its system to grow four to five times over the next five years as tenants electrify trucks, equipment and operations, potentially reaching up to 100 megawatts. Andre Basler, Director of Utilities for the Port of Oakland, noted that delivering 84% renewable and zero-carbon power means tenants now have access to one of the cleanest electricity supplies in California, and that the goal is to continue improving that supply as demand grows.
Investments in energy infrastructure
The Port continues to modernize, expand and replace electrical infrastructure to improve reliability and support electrification. In 2025, the Board of Port Commissioners approved a 20-year Energy Storage Services Agreement with Trolley Pass Project LLC, granting the Port 4 megawatts of capacity at a battery storage facility in San Bernardino County, which will help better harness solar power and reduce reliance on market purchases.
