California Wastewater Plant Energy Offset By Onsite Solar

Wastewater, in general, is not something we want to think about. But the energy required to move sewage from where it’s produced to where it can be effectively treated requires a lot of energy–and what better candidate for such a dirty job than clean, green solar energy?

MP2 Capital, a developer, financier and operator of solar projects throughout North America, recently announced the completion of a 250 kilowatt solar photovoltaic (PV) array at the Wastewater Treatment Facility in Winters, California. The project will be managed under a power purchase agreement with the city of Winters for a period of 25 years, during which it will provide the facility with approximately 10,700,000 kWh’s of juice aimed at offsetting the wastewater treatment plant’s energy use. The solar array includes 1,092 PV panels supplied by Canadian Solar and is expected to offset 10% of the total energy used by the wastewater treatment facility every year.

“While treating wastewater may not be glamorous, it is among the city’s most crucial — and costly — services,” said Elliot Landes, Associate, City of Winters, in a statement. “Partnering with MP2 Capital to implement this solar power project and cut energy costs at our wastewater treatment facility underscores our commitment to adopting renewable energy sources while at the same time providing the best service to our citizens at a cost-effective rate.”

The solar electricity plant is run by a computer monitoring system that rotates the panels to capture the most sunlight during the day, as well as interactive component in the form of an observation station that allows staff to monitor the power output of the array.
