What Manoa Energy does
Manoa Energy is a Tokyo-based developer and operator of utility-scale battery energy storage system (BESS) projects, founded in 2022 and operating as the Japan-based affiliate of infrastructure investor Brawn Capital. The company focuses on high-voltage grid-scale energy storage, with its flagship operational asset being the Helios 50MW project — a 50MW/104MWh BESS installation in Hokkaido, Japan, co-developed and co-operated with HD Renewable Energy Japan. The Helios project entered the Japan Electric Power Exchange (JEPX) market in December 2025 for day-ahead and intraday trading.
The company operates on a 100% merchant basis, without reliance on long-term offtake contracts, generating revenue from energy arbitrage on the JEPX wholesale market. First-year revenue from the Helios asset is forecast at approximately JP¥2 billion (US$12.8 million), with plans to add capacity market participation by 2028 as a second recurring revenue stream. Battery hardware is sourced through a strategic partnership with Chinese manufacturer Hithium, providing supply security for the company's expansion pipeline.
Manoa's go-to-market is enterprise field sales targeting infrastructure investors and energy market operators across the Asia-Pacific region. The company has set a strategic pipeline target of 3GWh of BESS deployments across Asia-Pacific by 2030, with 300MWh scheduled for delivery by 2027. This positions Manoa as a scaling Japan-anchored platform within Brawn Capital's broader energy infrastructure investment thesis, addressing grid stability, renewable integration, and energy price volatility in Asia-Pacific power markets.
