4 FAQs about Tokyo distributed energy storage requirements

Does Tokyo Gas have a battery energy storage system?

Tokyo Gas is also participating in the Japanese utility-scale battery energy storage system (BESS) market, signing a 20-year tolling offtake deal with Australian developer Eku Energy for a forthcoming 30MW/120MWh project.

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.

Is there a legal framework for energy storage?

No clear legal framework applies to energy storage. However, recently, based on a request from general transmission and distribution utilities, and in order to facilitate grid connections, some utility-scale renewable power projects have introduced behind-the-meter storage facilities.

Why is Tokyo launching a virtual power plant?

The push is reinforced by Tokyo’s 2025 regulation requiring solar panels on new homes, and the launch of virtual power plant (VPP) programs—slated to begin in fiscal 2026—that will let households sell surplus energy to the grid.
