The power solutions arm of Mitsubishi Heavy Industries will deploy three co-located battery storage projects for Origis Energy in the Southeast United States.

Florida-headquartered Origis has contracted Mitsubishi Power Americas to deliver three utility-scale battery energy storage system (BESS) projects totalling 150MW/600MWh. The projects will be co-located with solar facilities, will utilise the firm’s Emerald storage solution and will come online over the next two years.

A press release did not reveal which states the projects would be in. Of the 32 US projects listed on Origis’ site, 10 are in Florida, another 10 are evenly split between Georgia and Mississippi, with the remainder spread among the rest of the Southeast US (a region comprising around 14 states) and a few elsewhere in the country.

The project awards are nonetheless notable for being large-scale deployments outside of Texas and California, which continued to dominate the US’ BESS market of deployments in Q3. A broadening out of the market outside those two was highlighted by Mitsubishi Power Americas’ Senior VP Energy Storage Solutions Thomas Cornell in comments recently given to Energy-Storage.news.

“One of the biggest steps forward we have seen as an industry is the increased confidence and adoption in battery energy storage outside of the mature markets in the United States, including California and Texas. Mitsubishi Power is seeing this within our business with the projects awarded in the Southeast United States and Chile,” he said.

“As more battery energy storage assets are successfully commissioned and continue to meet customer expectations, it is resulting in more confidence and understanding of the many roles battery energy storage has in the energy landscape as a generation and transmission asset.”

Origis said the BESS units will enable it to add grid services to renewable energy generation. The company has 4GW of operational or contracted solar and storage in the US, and 2.3GWh of BESS contracted and 13.7GWh being developed.

Kenneth Kim, Vice President, Engineering & Strategy Planning, Origis Energy: “By adding the BESS solution to these facilities, we increase the value of the asset, adding enhanced grid solutions to clean, cost-effective solar power.”

Emerald is a lithium iron phosphate (LFP) based BESS product with up to six hours’ duration, although the three projects will be four-hour systems. They will also utilise Mitsubishi Power’s Emerald Integrated Plant Controller, its energy management system (EMS), and its Supervisory Control and Data Acquisition (SCADA) system which will instruct the BESS’ charging and discharging activities and monitor its health.

The firm has over 2.5GWh of utility-scale BESS projects at varying stages of development globally.
