SDG&E Selects Mitsubishi Power's Emerald Storage Solution for New Storage System

LCG, March 18, 2022--San Diego Gas & Electric Company (SDG&E) has awarded Mitsubishi Power an order for a 10 MW / 60 MWh battery energy storage system (BESS) for its Pala-Gomez Creek Energy Storage Project in Pala, California. The project will add capacity to help meet high energy demands, support grid reliability and operational flexibility, maximize use of renewable energy, and help prevent outages during peak demand.

SDG&E’s Director of Advanced Clean Technology stated, “SDG&E is committed to achieving net-zero greenhouse gas emissions by 2045. We are increasing our portfolio of energy storage assets to reach this goal. These assets enhance grid reliability and operational flexibility while maximizing our use of abundant renewable energy sources in California.”

Mitsubishi Power’s Emerald storage solution for SDG&E includes full turnkey design, engineering, procurement, and construction, plus a 10-year, long-term service agreement. The project is scheduled to be online in early 2023.

The BESS solution will repower an existing energy storage site. The design includes lithium iron phosphate (LFP) battery chemistry for added physical safety. The storage solution will include Mitsubishi Power’s 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.

Mitsubishi Power Americas’ Senior Vice President, Energy Storage Solutions, stated, “As more and more renewables come online during the energy transition, BESS solutions are essential to support a reliable and stable grid. We look forward to providing SDG&E with our BESS solution to add capacity, energy, and ancillary services to California’s grid. Mitsubishi Power’s Emerald storage solutions are enabling a smarter and more resilient energy future for our customers in California and around the globe.”

The BESS project is Mitsubishi Power’s eighth in California and will increase the total capacity to 280 MW / 1,140 MWh of storage to help meet California’s clean energy goals.
