Mitsubishi Power to supply Emerald BESS to SDG&E storage system projects

San Diego Gas & Electric Company (SDG&E) has announced that it has ordered Mitsubishi Power's Emerald storage solutions for four storage system projects. utility-scale battery energy storage system (BESS) totaling 39 megawatts (MW)/180-megawatt hours (MWh).

The Elliot, Clairemont, Paradise, and Boulevard microgrid BESS projects will connect to existing infrastructure in the San Diego region to provide reliable capacity and strengthen grid resilience amid high power demands in hot weather. summer days and peak hours of the night.

Emerald's storage solutions include the Emerald Integrated Plant Controller, which is an Energy Management System (EMS) and Supervisory Control and Data Acquisition (SCADA) system with a real-time BESS operation and monitoring/supervision control platform. These control features will help ensure that critical utility facilities, including fire, medical, emergency management, and law enforcement facilities, are powered during peak demand and unexpected outages.

"We live in a time in which the growing threats of climate change and extreme heat waves can increasingly affect the reliability of the network", said the director of Advanced Clean Technology of SDG&E, Fernando Valero. 

"By expanding our energy storage portfolio, we are helping our region and critical community facilities become more resilient."

The BESS microgrid projects, approved by the California Public Utilities Commission on June 23, are scheduled to come online in mid-2023.

Tom Cornell, Senior Vice President, Energy Storage Solutions, Mitsubishi Power Americas, said, "SDG&E was an early adopter of battery energy storage in the western United States and continues to be a leader in battery storage implementation. energy to serve its customers. We are excited to make an impact with SDG&E on these four microgrid projects, in addition to the Pala-Gomez Creek energy storage project announced earlier this year."
