California, United States [RenewableEnergyWorld.com] West County Wastewater District (WCWD), Solar Power Partners Inc. and Premier Power Renewable Energy jointly announced the completion of a 1-megawatt (MW) solar energy system designed to replace 35 percent of WCWD’s annual electricity usage with clean, renewable solar energy at zero out-of-pocket costs.
Solar Power Partners, which owns and operates the solar equipment, set up a power purchase agreement (PPA) with WCWD. Premier Power located 89 dual-axis trackers, manufactured by ET Solar, across the WCWD Richmond treatment facility site, including 28 trackers that rise above the potential high-water line of a storm-water storage pond.
Premier Power built all of the tracking towers to withstand flooding and submersion while meeting all seismic restrictions and solving soil engineering challenges. The company also designed the system to produce approximately 1.97 million kilowatt-hours (kWh) of electricity annually.
“The West County Wastewater District is a great example of a public entity acting as an environmental steward in its daily operations. Their strong environmental record is now enhanced by their use of clean renewable power to power the plant,” said Alex von Welczeck, president and CEO of Solar Power Partners. “This project is also a perfect example of where a municipal entity can join hands with the private sector to deploy solar at no cost to the ratepayers. WCWD is making dual-purpose use out of its land, helping solve global warming and building budgeting stability for its ratepayers. We are proud to count WCWD as our customer.”
