Company selected by SDG&E for its 'Emerald' power solution
Big names are getting into the energy storage game. The latest to do so is San Diego's main utility provider, who recently enlisted the services of Mitsubishi Power.
"San Diego Gas & Electric Company (SDG&E), a regulated investor-owned utility providing energy service to 3.7 million people, ordered Mitsubishi Power’s Emerald storage solutions for four utility-scale battery energy storage system (BESS) projects totaling 39 megawatts (MW) / 180 megawatt hours (MWh)," according to a joint press release August 11. "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 resiliency amid high energy demands on hot summer days and peak evening hours."
The Emerald storage solutions include the 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. These control features will help ensure that critical public service facilities including fire, medical, emergency management, and police are powered during peak demand and unexpected outages.
“We live in a time when growing threats from climate change and extreme heat waves can increasingly impact grid reliability,” said SDG&E Director of Advanced Clean Technology Fernando Valero. “By expanding our energy storage portfolio, we are helping our region and critical community facilities become more resilient."
The microgrid BESS projects, approved by the California Public Utilities Commission on June 23, are slated to be 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 it continues to be a leader in deploying energy storage to serve its customers. We’re 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.”
In May 2022, Mitsubishi Power was awarded cybersecurity certification IEC 62443 ML2 for the Security Development Lifecycle Process (SDL), which validates that all products developed for its Emerald storage solutions, including hardware control technology, follow rigorous policy and processes aligned to industry best practices.
Mitsubishi Power will support its Emerald storage solutions for SDG&E with a 10-year Long-Term Service Agreement.
