Prudent Energy is the recipient of a grant from the California Public Utilities Commission (CPUC), which will go towards the construction and operation of a Vanadium Redox Battery Energy Storage System (VRB-ESS) with SunPower’s PV systems. The grant and construction of the system will be completed in cooperation with SunPower, Pacific Gas and Electric (PG&E), KEMA and Sandia National Laboratories of the U.S Department of Energy (DOE).
“We are very excited to join SunPower, the CPUC, DOE, PG&E, and our other partners in this project,” said Jeff Pierson, Prudent Energy's senior vice president. “Prudent's Vanadium Redox Battery is an excellent fit in the distributed solar market. We expect to give California ratepayers what they want most – major savings on their electric utility bills.”
Prudent’s VRB-ESS energy storage system works similarly to a rechargeable fuel cell, where chemical energy is converted into electrical energy in a quick manner. The partnership between Prudent’s VRB-ESS and SunPower’s PV systems is expected to allow SunPower customers to lower their energy costs by using power stored through Prudent’s energy storage system.
