About Energy storage battery subsidies
There are several subsidy programs available for Battery Energy Storage Systems (BESS):In Poland, there are new subsidy schemes under legislative review with budgets of PLN 4 billion and €200 million to support businesses investing in lithium-ion technology and grid infrastructure1.In Japan, the government has introduced subsidies for battery storage equipment purchases and project construction costs, with a total of JPY 9 billion allocated for these initiatives2.Additionally, Japan's government is promoting stationary battery storage and power grid expansion to support renewable energy capacity, which is also linked to subsidy programs3.The Sustainable Open Innovation Initiative in Japan has awarded 34.6 billion yen in subsidies for projects that expand renewable energy through energy storage4.These programs are part of broader efforts to enhance energy systems and support the transition to renewable energy sources.

6 FAQs about [Energy storage battery subsidies]
How has government subsidy impacted battery storage?
The government’s subsidy push has so far prompted an increasing number of private companies to invest in battery storage projects, including large-scale plants. With countries around the world pushing to accelerate their renewable deployments, it is more important than ever to maximize solar electricity generation.
Can battery aggregators promote energy storage systems in Japan?
The Japanese government has published list of battery aggregators that successfully applied to a scheme to promote energy storage systems.
Will battery storage reduce the cost of a power grid upgrade?
OCCTO estimates that the annual cost of integrating more renewable generation into the power grid could reach ¥353 billion in 2050 and the rate of curtailment could reach 52% if the transmission network is not upgraded. Installing battery storage would reduce the cost of upgrading the grid and avoid wasting clean generation.
How subsidized energy storage system works?
The subsidized ESS must charge and discharge on demand and are not allowed to charge during peak hours or discharge during valley hours. Besides policies tailored-made for each applications, supportive policies and the ToD tariff boost the development of energy storage industry.
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.
How important is battery energy storage in Japan?
Battery energy storage systems (" BESS ") are playing an increasingly important role in the transition towards net zero. However, the regulations for BESS in Japan were generally perceived as requiring further clarification and development to promote this industry.
