Most Facilities Pay for Electricity — This Treatment Plant Creates Its Own

The Hayward Water Pollution Control Facility uses solar panels in tandem with a cogeneration system to produce electricity.

Through the innovative use of a solar array installed in 2010 and a state-of-the-art cogeneration system installed in 2014, the Hayward (San Francisco) Water Pollution Control Facility has attained net zero energy. Jeff Carson, manager of operations and maintenance, takes viewers on a guided tour of the plant, which sends its unused energy to the power grid from a photovoltaic 1-megawatt system. A master control panel lets the utility view electrical production and export information to its energy authority, which then credits the account.
