HDJP acquires majority stake in 50MW/104MWh battery project in Hokkaido

It is expected be operational by end-2025.

HD Renewable Energy Japan (HDJP) has acquired a majority stake in the 50MW/104MWh Helios I battery energy storage system (BESS) project in Sapporo, Hokkaido, through a Tokumei Kumiai interest purchase agreement with Brawn Capital.

Developed by Manoa Energy and managed by Brawn Capital, Helios I is set for completion and operational launch by the end of 2025. Hokkaido Electric will oversee construction and site maintenance.

The project aligns with Japan’s goals of grid stability and decarbonization, particularly as the country faces increasing solar curtailment. BESS systems such as Helios I will store excess energy generated during high production periods and release it during peak demand, supporting the government's carbon neutrality target by 2050 and its aim for renewables to comprise at least 40% of the energy mix by 2040.

Brawn Capital has a track record in Japan’s energy transition and is currently developing over 1GW of BESS projects.

Financial advisory firm Finergreen acted as Brawn Capital’s exclusive sell-side advisor, providing support in structuring the transaction, managing due diligence, and coordinating negotiations.
