Document Description
The Twin Cities Solar and Battery Energy Storage System Project includes the construction and operation of a PV solar power and battery storage facility and interconnection facilities, including a generation substation and interconnection tie-lines that would interconnect into the Rancho Seco Switchyard via a new 230 kV interconnection line. The project would provide new power production capacity of up to 275 MW and allow storage of 275 MW at the BESS facility, which would be delivered at the point of interconnection with the electrical grid managed by SMUD. The solar panels and associated infrastructure would be located on approximately 1,328 acres of land within the 1,697-acre project site. The Rancho Seco Switchyard would be modified to accept the new interconnection.
