ForeFront Power is celebrating the completion of a 5-megawatt solar project at the Eastern Wastewater Treatment Plant (EWWTP) in Vacaville, California. There is also an energy storage system on site, but the specific details of the system scale have not been announced yet.

The EWWTP system will generate nearly 8.1 million kWh of renewable energy electricity annually. The system aims to offset the annual electricity demand of EWWTP facilities and is expected to save the city over $25 million in electricity bills.

Vacaville's sustainable development goals are about bringing better outcomes to people - healthier air, smarter resource utilization, and reliable public services, "said Vacaville Mayor John Carli. By combining solar energy with intelligent battery storage in an industrial facility that processes 7.5 million gallons of wastewater per day, this project will help power operations that are critical to minimizing public health risks and our environmental impact.

EWWTP's solar and energy storage systems were developed through a 20-year PPA (Power Purchase Agreement) signed between the city and ForeFront Power. According to the terms of the PPA, ForeFront Power owns and maintains the system, while the city purchases electricity at a fixed low price lower than the utility company, ensuring long-term budget predictability and avoiding the impact of rate increases. ForeFront Power will continue to operate and maintain the system free of charge to the city during the PPA period.
