Increased generation of renewables requires various forms of energy storage to manage the issues associated with intermittency. Japan has, therefore, introduced two CAPEX subsidy schemes for grid-scale battery developers, excluding co-located projects.
The subsidy covers up to 2 billion yen per project. A total of 12 projects totaling 180MW/595.3MWh was awarded 13 billion yen through Tokyo's FY2024 subsidy for promoting grid-scale battery storage, the metropolitan government's document released in February 2025 shows.
Kentaro Ono says that Hirohara BESS' tolling deal and the Eshi project's LTDA contract are two of three commercialisation pathways Eku Energy sees potential for in Japan. The third is a full merchant model. Ono says the developer wants to hold a diversified portfolio representing different risk and reward appetites for investment.
Sho's colleague, Eku Energy Japan managing director Kentaro Ono, explains that the METI subsidy covers up to 30% of the Capex cost for large-scale BESS. The Tokyo Metropolitan Government scheme, meanwhile, is for projects both in and outside the Tokyo area and covers up to 50% of the Capex.
