SDG&E selects Mitsubishi energy storage system to boost flexibility
San Diego Gas & Electric (SDG&E) awarded Mitsubishi Power an order for a 10 MW / 60 MWh energy storage system for its Pala-Gomez Creek Energy Storage Project in Pala, California.
The battery energy storage system (BESS) is intended to add capacity to help meet high energy demand, support grid reliability and operational flexibility, better maximize the use of renewable energy and help prevent outages during peak demand.
The BESS project is Mitsubishi Power’s eighth in California, bringing total capacity to 280 MW / 1,140 MWh.
The contract includes full turnkey design, engineering, procurement and construction, as well as a 10-year long-term service agreement. It is scheduled to be online in early 2023.

The project will repower an existing energy storage site. Mitsubishi Power will supply its Emerald Integrated Plant Controller, which is an Energy Management System (EMS) and Supervisory Control and Data Acquisition (SCADA) system with real-time BESS operation and a monitoring/supervisory control platform.
The batteries are expected to use lithium iron phosphate (LFP) battery chemistry, which Mitsubishi said provides longer life and better thermal stability and chemical stability.
