Potrero Power Station

The Potrero Power Station site offers a unique opportunity to open up a large portion of the City’s Central Waterfront to the public for the first time in 150 years. Envisioned as a mixed-use project, the site will be the location of new homes, office uses, laboratory uses, retail, PDR, community facilities, and nearly 7 acres of open space. Visit the tabs below for additional project information.

Notice of Public Hearing Board of Supervisors of the City and County of San Francisco Land Use and Transportation Committee for April 13, 2020 - see Timeline tab for details.

While industrial uses will continue to be an important element of the urban fabric in the Central Waterfront, including on this site, the City’s Central Waterfront Area Plan identifies the site as a location for additional growth and a wider range of land uses, including residential, commercial, and parks.

In 2016, Associate Capital/California Barrel Company (Project Sponsor) purchased the Potrero Power Station from then-owner NRG Energy.  In 2017 they began an extensive planning process with City agencies and the community to develop a master plan for the site. This planning work is supported by a prior Settlement Agreement, signed by Mirant and the City, which commits the City and property owner to collaborate on a redevelopment proposal for the site. In late 2017 Associate Capital initiated preparation of the environmental impact report for the master plan. Also around this time, Pacific Gas & Electric (PG&E), an earlier owner of the site, began environmental remediation, an effort that is ongoing under the review of the Regional Water Quality Control Board. The overall vision is for the Potrero Power Station—along with the Pier 70 site just to the north—to be a key element in the ongoing transformation of the Central Waterfront to a neighborhood that provides thousands of new homes and jobs, community-serving retail and services, new space for light industrial businesses, a hotel, several acres of new parks, community facilities, and unprecedented waterfront access. Once adopted by the Planning Commission and Board of Supervisors, the master plan and associated Development Agreement will guide long-term development on the site.

As envisioned, the proposed program for the project includes the following elements:

  • Approximately 2,400 dwelling units
  • Approximately 6 acres of open space, including both passive and active recreation areas, a playground, and waterfront access
  • 1.2-1.9 million gross square feet of commercial uses, which could include office, research and development/life science, retail, hotel, and production/distribution/repair (i.e. light industrial) uses
  • Approximately 100,000 gross square feet of community facilities
  • Approximately 925,000 gross square feet of parking
  • Building heights from 65 to 180 feet, as well as one building at 300 feet
  • Transportation and circulation improvements, shoreline improvements, and utilities infrastructure improvements
  • Preservation of the iconic stack structure as well as potentially the adjacent Unit 3 power block; design standards and guidelines in the master plan will govern new development on the site to ensure compatibility with on-site and adjacent historic structures and districts.

Included in the 29-acre site is a 4.8 acre parcel at the corner of 22nd and Illinois Streets currently owned and operated by PG&E as an electrical switchyard. PG&E granted the Project Sponsor approval to include this switchyard site in its planning and environmental clearance for the project.
