PowerX, Inc. signed an MOU on May 7 with Electric Power Company (EPCG), Montenegro’s state-owned power utility, to partner on Battery Energy Storage Systems (BESS).
PowerX is headquartered in Tamano City, Okayama Prefecture, and led by President and CEO Masahiro Ito. The company trades under Securities Code: 485A.
The MOU sets an indicative target of approximately 500 MWh of BESS capacity over an initial three-year period to support the large-scale integration of renewable energy and strengthen grid stability in Montenegro.
Montenegro adopted its National Energy and Climate Plan in December 2025, setting 2030 targets that include a minimum 50% share of renewable energy in gross final energy consumption. EPCG, the country’s largest electricity producer, has identified BESS as a key component of its grid modernization and renewable energy integration efforts.
Under the MOU, the parties will collaborate together to identify optimal BESS deployment plans to support grid reliability, peak shaving, and frequency regulation, with comprehensive after-sales support. PowerX will also explore the potential establishment of local BESS assembly capabilities in Montenegro.
Montenegro’s EU candidate status, coupled with its power interconnection with Italy, makes the country a strategically important market for clean energy infrastructure in Europe. PowerX aims to leverage this cooperation as a foundation for expanding its BESS business into the European market.
“Battery energy storage systems are becoming a core part of modern energy infrastructure, enabling greater integration of renewable energy while supporting grid stability, flexibility, and resilience,” said Masahiro Ito, CEO of PowerX. “As Japan’s leading BESS provider, PowerX is pleased to partner with EPCG to support Montenegro’s energy transition and the modernization of its power system. Through this strategic cooperation, we aim not only to deploy advanced battery storage solutions, but also to build a long-term foundation for PowerX’s activities in Montenegro and the wider region, including the development of local battery system assembly capabilities.”
EPCG CEO Zdravko Dragaš said the partnership is a key step in modernizing Montenegro’s power grid. He added that it shows EPCG’s focus on clean energy and innovation.
Working with PowerX will give them access to advanced battery storage tech. Dragaš said this tech is critical for adding more renewable energy to the grid and keeping Montenegro’s power supply secure in the long run.
