The City of Hayward’s Water Pollution Control Facility (WPCF) is an award-winning green energy generating site and the first publicly owned treatment works and largest generating account in the California RES-BCT (Renewable Self Generating Bill Credit Transfer) Program. Since the completion of the 1,132 kilowatt (kW) cogeneration facility in 2014, it has been generating an average of 750,000 kilowatt hour (kWh) monthly, allowing virtually all of the solar energy generated on site to be exported to PG&E.
