Japan’s Daiwa Takes 49% Stake in Enfinity Global Battery Storage Projects in US and Europe

Daiwa Energy & Infrastructure (DEI) has acquired a minority interest in two major battery energy storage system (BESS) projects developed by independent power producer Enfinity Global, according to a joint announcement made by both companies on June 4.

Under the agreement, DEI will take a 49% equity stake in a total of 380MW of battery storage assets. These include a 250MW/500MWh (2-hour duration) project located in ERCOT, Texas, and a 130MW/520MWh (4-hour duration) project in Veneto, northeastern Italy.

DEI, a subsidiary of Daiwa Securities—one of Japan’s largest investment banks—was established in 2018. The company has focused on direct investments in sectors such as battery storage, data centers, solar PV, wind, and other core infrastructure areas.

DEI made its initial foray into the Texas battery storage market in April 2024 through a co-development partnership with Stella Energy Solutions. That collaboration involved the Thomas Cameron BESS, a 200MW/480MWh project expected to provide energy and ancillary services in ERCOT beginning 2026.

Additionally, DEI recently partnered with Chinese battery manufacturer and storage system integrator Gotion High-Tech to pursue the deployment of 1GWh of BESS projects in Japan.

Founded in 2019, Enfinity Global manages a 35.5GW global portfolio of renewable energy and energy storage projects that are either operational, under construction, or in development. This includes 1.1GW of operating renewable capacity.

Enfinity has been active in markets such as Italy, Japan, and the United States, and gained further attention after acquiring two ERCOT BESS projects totaling 425MW/850MWh in January, bringing its U.S. battery storage pipeline to 6.6GW.

According to the companies, the Texas project in which DEI is investing is scheduled for commercial operation in Q4 2026, while the Italian project in Veneto is expected to go online in Q4 2027.
