SVCW installed two new cogeneration engines that operate using biofuel (methane gas) to produce electricity and heat, associated biofuel treatment system, electrical components, structural modifications, Supervisory Control And Data Acquisition (SCADA) programming, and piping/valves. SVCW’s new cogeneration engines replaced an engine that had reached the end of its useful life. 

Operating since January 2015, Cogeneration supplies electricity to process equipment and reduces the electricity SVCW purchases from Pacific Gas and Electric Company (PG&E). Heat from the engines is used to warm digesters and buildings to reduce natural gas purchased from PG&E. 

By consistently producing over 60% of the treatment plant's electrical demand, estimated annual savings from cogeneration is $1.1 million in fiscal year 2017-18.
