Canadian energy company AltaGas Ltd has signed a deal to bring 20MWs of lithium-ion battery power to southern California, US.
The firm, through its wholly owned subsidiary AltaGas Pomona Energy Storage, has signed a 10 year Energy Storage Resource Adequacy Purchase Agreement with Southern California Edison (SCE).
The cells will be made by Samsung, with Greensmith Energy Management Systems supplying the battery systems, and will also integrate its software control platform and power conversion technology.
AltaGas will build, own and operate the AltaGas Pomona Energy Storage Project, which is expected to cost between $40-$45 million.
The system at AltGas’ Pomona Facility in the east Los Angeles Basin will be among the largest battery storage projects in North America when it comes on line by the end of this year.
Under the terms of the agreement AltaGas will provide SCE with 20 MW of resource adequacy capacity for a continuous four-hour period, the equivalent of 80 MWh of energy discharging capacity.
The deal will see AltaGas receive a fixed monthly resource adequacy payments and retain the rights to earn additional revenue from excess energy from the battery system.
AltaGas will retain overall project management, execution and operations of the Project.
