The largest flow battery system in the world, capable of storing and delivering grid-scale power instantaneously, has received permission to operate from the local utility and will begin full operation in the weeks ahead, announced Prudent Energy, the manufacturer of the VRB Energy Storage System. The project’s commissioning marks a significant point in the deployment of large-scale electricity storage systems and will be used to expand onsite power generation at an agricultural processing facility in California owned by Gills Onions, a leader in sustainability, innovation, and technology.
“This project unleashes the power of energy storage for industrial companies and the grid of the future. It proves that multi-megawatt-hour VRB systems can be delivered today. We expect dramatic benefits for a company like Gills Onions, to help them manage their operating costs,” says Prudent Energy Senior Vice President Jeff Pierson.
“Prudent Energy storage is clean, quiet and safe, making it an attractive, sustainable solution for onsite power generators like us. We are impressed with the innovative technology behind Prudent’s Vanadium flow battery, and are excited to be the first company in the United States to deploy a VRB system on this scale,” says Steve Gill, Owner/Partner of Gills’ Onions.
“Lower Utility Bills on a Sustainable Basis”
One of the VRB system’s obvious benefits is that it allows Gills Onions to reduce utility bills by storing electricity when rates are lowest and delivering that electricity during expensive peak rate periods. Electricity prices increase during high use periods, especially for six hours in the afternoon when the local utility, Southern California Edison, must call on peaking generators to meet demand. That additional cost of electricity production is passed to the customer via Time of Use (TOU) rates.
