These are the Ministry of Economy, Trade, and Industry (METI) and the Tokyo prefectural subsidies. There are a series of requirements to be eligible: projects must have a minimum capacity of 1 MW, the battery must be able to participate in various markets, and the battery must be directly connected to the grid. The Market for Energy Storage
A Growing Need for Energy Storage The increasing generation of renewables on the Japanese grid has led to various support policies and CAPEX subsidy schemes to support the deployment of grid-scale Battery Energy Storage (BESS).
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.
As Japan works to expand battery storage amid growing solar and wind capacity, METI also runs a similar subsidy scheme at the national level. In FY2024, it awarded 34.6 billion yen to 27 projects. Both programs are expected to continue in FY2025.
