Battery energy storage subsidy

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.

Why is Japan extending subsidies to stand-alone battery storage facilities?

In Japan, the extension of subsidies to stand-alone battery storage facilities affirms the Japanese government's commitment to transition to renewable energy. It is expected that the introduction of stand-alone battery facilities will ease grid related issues and mitigate connection related risks faced by renewable energy projects.

Are battery energy storage systems a viable option in Japan?

Interest in battery energy storage systems (BESS) has been growing globally and Japan is no exception. In Japan, stand-alone BESS businesses in which battery storages are installed independently to the electrical power grid have emerged, and the Japanese government has updated the legal system to facilitate the expansion of such stand alone BESS.

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.

Why are battery storage projects growing in Japan?

The ramp up of battery storage projects in Japan continues apace, aided by growing subsidy avenues and rising volumes on various electricity markets, from spot to balancing to capacity.
