The Viejas storage facility will get its electricity by integrating about 30,000 photovoltaic solar panels at parking garage carports and commercial areas around the resort. hours when California’s grid is under the most stress. Storage systems take solar power generated during the day and discharge the electricity later, especially during the 4-9 p.m. Energy storage - particularly from batteries - is seen as a key way to fill the gaps.

And when the wind doesn’t blow, production from wind farms peters out. Solar production may be abundant during the day but practically vanishes after sunset or when smoke and clouds obscure the skies. “What we’re doing with our long-duration storage program is really (seeking) eight-hour to 100-hour chemistries.”Įnergy storage has taken on a higher profile in recent years as more renewable sources of power have come onto the electric grid. “As we are increasing renewables on the grid, we need different forms of storage to provide different benefits,” said David Hochschild, California Energy Commission chair. That’s attractive to the energy commission since California expects that more than 48,000 megawatts of battery storage and 4,000 megawatts of long-duration storage will be needed by 2045 to meet the state’s clean-energy mandates. Zulch said the batteries are designed to run for 10 to 12 hours, which is much longer than many storage systems that discharge for about four hours. But they don’t catch fire and they don’t wear out.” You’re never going to see them in a car or a truck or a cellphone. “That’s why the California Energy Commission wants to support it. “The thing about vanadium flow batteries is that they’re designed specifically for stationary energy storage,” Zulch said. Once installed, Invinity CEO Larry Zulch said the vanadium redox flow battery system at Viejas is expected to be the largest of its kind in North America. The 60-megawatt-hour system will use zinc hybrid cathode batteries from Eos Energy Enterprises, a company based in New Jersey, and vanadium redox flow batteries supplied by Invinity Energy Systems, an international company with offices in North America. The battery storage system, which is expected to be completed by summer, will help keep outdoor lighting on and provide power to other areas around the site.
