The EWWTP system will generate nearly 8.1 million kWh of renewable electricity annually. Designed to offset the annual electricity demand at the EWWTP facility, the solar and storage system is projected to save the city more than $25 million in electricity costs.

“Vacaville’s sustainability goals are about better outcomes for people — healthier air, smarter use of resources, and reliable public services,” said Vacaville Mayor John Carli. “By pairing solar with smart battery storage at an industrial facility that treats an average of 7.5 million gallons of wastewater daily, this project will help power operations essential to minimizing public health risks and our environmental impact.”

The EWWTP solar and storage system was developed through a 20-year PPA between the city and ForeFront Power. Under the terms of the PPA, ForeFront Power owns and maintains the system, while the city purchases the electricity at a fixed, lower rate than the utility, ensuring long-term budget predictability and protection from rate increases. ForeFront Power will continue to operate and maintain the system for the duration of the PPA at no cost to the city.
