    CHP is a reliable, cost-effective option for waste water treatment plants. The biogas flow from an anaerobic digester can be used as fuel to generate electricity and heat in a combined heat & power system. The thermal energy produced by the cogeneration system can then be used to meet digester heat loads and for facility electricity, heating or cooling. 

    Benefits of CHP at WWTPs: 

    • Produces power below retail electric prices.
    • Displaces cost of thermal needs. 
    • Renewable fuel source.
    • Increases reliability.
    • Produces useful energy. 
    • Reduces emissions of greenhouse gases.

    This 800 kW CHP system utilizes digester gas from the wastewater treatment process to generate renewable electricity and heat for the facility’s operations. As a result of this new system, all the biogas produced by HARRF’s anaerobic digestors, which was previously flared, is now utilized to generate sustainable green energy.

    The City of San Luis Obispo’s Water Resource Recovery Facility (WRRF) is responsible for treating all of the wastewater (sewage) within the City, Cal Poly and the County airport. The facility treats 4.5 million gallons of wastewater daily, twenty four hours a day, 365 days a year. This wastewater treatment plant using a 2G Energy 150 kW CHP treats 1.7 billion gallons of sewage from the city, Cal Poly and the county airport annually.
