Port of Oakland Electricity 84% Clean in 2025
The Port's publicly owned utility reported that most of its 2025 power came from renewable and zero-carbon sources.
Updated on Nov. 3, 2026 in Utilities
Port Public Power, the Port of Oakland's publicly owned utility, said 84% of the electricity it delivered to 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 on October 22 for submission to the California Energy Commission.
Why it matters
Cleaner electricity supports the Port's efforts to reduce emissions as more operations shift to electric power. Electrification across the Seaport and Oakland San Francisco Bay Airport can also reduce local tailpipe emissions.
The Port's electricity supply was 61% renewable and 21% large hydroelectric, compared with a 46% average renewable share for California utilities. Its greenhouse gas intensity was 186 pounds of CO2 equivalent per megawatt-hour, roughly half the 384-pound average for California utilities.
The players
Port of Oakland
The Port of Oakland is a public agency that operates the Seaport and Oakland San Francisco Bay Airport on the San Francisco Bay.
Port Public Power
Port Public Power is the Port of Oakland's publicly owned utility and a member of the Northern California Power Agency.
Trolley Pass Project LLC

The details

Timeline
2025: Port delivered 84% renewable and zero-carbon electricity and the Board approved the 20-year battery storage agreement.
October 22: Board approved the Power Source Disclosure Report and Power Content Label.
Industry Context
The Port's annual disclosure filing follows the reporting framework of the California Energy Commission's Power Source Disclosure Program, which requires utilities to publish their power mix and emissions each year. Its 84% clean share and 186-pound emissions intensity sit well above the statewide utility averages of 46% and 384 pounds, respectively.
Electrification of Port operations can reduce tailpipe emissions in Oakland's Seaport and airport areas. The Port intends to keep its electricity supply getting cleaner as demand grows.
The takeaway
Public utilities that report their power mix annually give residents a way to track whether local electricity is getting cleaner as demand rises. Watching the Port's future disclosures will show whether that trend holds.
What happens next
Port Public Power expects its electricity demand to grow four- to five-fold over the next five years, with total demand possibly reaching 100 megawatts.
