Tehachapi Energy Storage Project
A modern-day energy storage pioneer in utility-scale energy storage
Battery-based Grid Energy Storage System
Tehachapi Energy Storage Project (TSP) is a lithium-ion battery-based grid energy storage system at the Monolith Substation of Southern California Edison (SCE) in Tehachapi, California. Located in a valley 100 miles northeast of Los Angeles within the Tehachapi Wind Resource Area, the project could supply 32 megawatt-hours of electrical energy and 8 megawatts of power for 4 continuous hours that could power between 1,600 and 2,400 homes.
Demonstrate the performance of lithium-ion batteries used to store power from hundreds of wind turbines under real-world conditions.
System models, RTDs and simulations. PowerStore Battery (8MW / 32MWh), eMesh Control System
Battery energy storage system for wind and solar energy sources which can later be dispatched onto the grid when customers need and use it most.
Transforming the Battery Storage Industry
The Tehachapi project transformed the lithium-ion battery storage industry by propelling the development of commercial products, and contributed to the integration of renewable and storage-based resources on California's grid. The project assessed the capability and effectiveness of storage to support 13 operational applications.
- Establish smart grid program.
- Assess the capability and effectiveness of storage to support 13 operational applications
- Sufficient to power between 1,600 and 2,400 homes for four hours.
- In 2020, SCE reported that TSP operated in the wholesale energy market with revenue exceeding operating and maintenance costs.
