WE has connected its first utility-scale battery energy storage system (BESS) to a California independent system operator. The project, Fifth Standard, is scheduled for completion in August 2023 and also includes a 150 MWac solar PV facility,. The BESS facility, at 137 MWac, 548 MWh, is located in Fresno County California. The company's largest to date, the site has the capacity to provide 137 MW to the grid over a four-hour period.
Mark Noyes, CEO of RWE Clean Energy, comments: "Projects like Fifth Standard, with its co-located battery storage system, will become increasingly important to help ensure that as renewables form a bigger part of the energy mix, the electricity produced can be used when it is needed most. In our case, future growth is backed by project development pipeline comprising more than 24 GW in onshore wind, solar and battery storage, one of the largest in the USA."
Located 45 miles SW of Fresno, Fifth Standard includes 369 334 PV panels and covers 1,600 acres. The project supports California's clean energy goals as the state works toward its net zero goal of 2045. The solar panels onsite will include a racking system with solar trackers, and excess energy not sent to the grid will be stored in the on-site BESS.
Fifth Standard is expected to generate up to US$10 million in revenue to local taxing jurisdictions during its lifetime.
