Does japan have energy storage subsidies

Does Japan have a battery subsidy program?

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.

Does Japan have a capex subsidy scheme for grid-scale battery developers?

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.

How much money does Japan spend on energy storage?

For the scheme ‘Support for the introduction of energy storage systems for home, commercial and industrial use’, the Japanese government has allocated around JPY9 billion (US$57.48 million) from the FY2023 supplementary budget.

How can Japan encourage investment in energy storage?

Japan’s development of revenue streams through its wholesale, capacity, and balancing markets, coupled with CAPEX subsidy schemes for grid-scale battery projects, provides a framework to encourage investment in energy storage.

How much does Tokyo's FY2024 subsidy cover?

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.

What are Japan's new battery energy storage regulations?

The government is also reforming its battery energy storage system (BESS) regulations, with batteries set to play an important role in maximizing renewable energy supply and avoiding grid constraints. We look at the changes being implemented and what they mean for renewable energy projects in Japan.
