CleanCapital, a leading independent power producer focused on distributed renewable energy, today announced that it has acquired a majority interest in a 7.7 MW / 30.8 MWh portfolio through a joint venture with Osaka Gas USA. CleanCapital will be the managing member and maintain the joint venture relationship with Osaka Gas USA.

The acquired portfolio consists of a pair of operating standalone battery energy storage systems (BESS) located on Staten Island in New York City. The two projects—Arlington and Littlefield—achieved commercial operation in July and August 2023, respectively, and participate in New York’s Value of Distributed Energy Resources (VDER) program. Under the program, NYU Langone Hospitals serves as the sole net‑crediting offtaker for both facilities.

The projects benefit from CleanCapital’s deep expertise and a network of experienced vendors and to provide battery and technical operations and maintenance services, including Energy Safety Response Group (ESRG), which manages BESS fire protection, emergency response, and Fire Department training.

“This investment reflects CleanCapital’s continued commitment to scaling reliable, resilient clean energy infrastructure in the markets where it is most urgently needed,” said Julia Bell, Chief Investment Officer at CleanCapital. “We are excited to work with Osaka Gas USA and to continue to grow our asset ownership and management with energy storage systems like these, which are essential to modernizing New York City’s grid and enabling affordable energy in high‑demand regions.”

“We are pleased to partner with CleanCapital on this acquisition as we continue to expand our presence in the U.S. power market,” said Shingo Morii, Senior Vice President at Osaka Gas USA. “Projects like these play an important role in strengthening grid reliability and resilience in New York City, while supporting the integration of clean energy and meeting growing demand. We look forward to working with CleanCapital and the project stakeholders to deliver long-term value through safe and reliable operations.”

As communities and businesses across the U.S. face increasing energy costs and tightening supply, energy storage has become a critical tool in ensuring grid reliability and stability. Energy storage assets like these help reduce strain during periods of peak demand, stabilize energy costs, and provide instantaneous support to the grid. At a time when energy demand is high and supply remains limited; strategic investments in storage are essential to building a more resilient, dependable energy future.
