Wärtsilä has supplied a 125 MW/250 MWh battery energy storage system to a REV Renewables project in California.
The LeConte battery storage facility, located in Calexico, is situated at a major junction point for energy producers in the California Independent System Operator and San Diego Gas & Electric territories that are importing and exporting energy between the U.S. and Mexico.
The facility will be used to follow the automatic generation control signal to maintain system frequency and perform peak day operations to relieve congestion on transmission lines from the abundance of solar PV resources in the area.
LeConte marked Wärtsilä’s second-largest Engineering, Procurement, and Construction project to date.
The LeConte system was approved by the California Public Utilities Commission in early 2022 as part of a plan to build 15,000 MW of new energy storage and demand response resources by 2032 to ensure long-term reliability and meet the state’s Renewables Portfolio Standard.
Wärtsilä completed construction just in time to provide grid stability during California’s record-setting September 2022 heat wave.
REV Renewables owns the largest deregulated portfolio of energy storage assets in the U.S.
