TOKYO -- Japan will require power utilities to open up their grids to energy storage systems operated by other companies, aiming to promote a technology that will be key to broader adoption of renewable energy.
The government will also subsidize up to half the cost of battery storage systems, drawing from a 13 billion yen ($114 million) pot of funding in the fiscal 2021 supplementary budget, to make them competitive with other types of energy storage. It plans to solicit applications this fiscal year.
