The 983-kilowatt SunPower solar power system at Galt’s municipal wastewater treatment plant has been completed. The high-efficiency system is expected to generate the equivalent of approximately 90 percent of the wastewater treatment plant's electrical energy needs.
"We're very excited to be hosting a solar (energy) system at our wastewater treatment plant that will produce reliable, emission-free solar power," Mayor Barbara Payne said in a press release.
"SunPower is very experienced in working with wastewater treatment plants, and assisted us with securing the power purchase agreement that made the project affordable. The system will generate the equivalent of most of the electricity required at the facility, resulting in savings we can pass on to our rate payers."
Under the terms of the solar power purchase agreement, PNC Energy Capital, LLC, a member of the PNC Financial Services Group, Inc., owns the system that SunPower designed, built, operates and maintains.
Galt buys the electricity at prices below retail rates, providing a long-term hedge against rising power prices with no initial capital investment.
The system includes a ground-mounted system that rotates the solar panels to follow the sun during the day, increasing energy capture by up to 25 percent over conventional fixed-tilt systems, while reducing land use requirements, according to the city.
