Japanese green energy storage power supply call for consultation

What is Japan's energy storage policy?

As policy, technology, and decarbonization goals converge, Japan is positioning energy storage as a critical link between its climate targets and energy reliability. Japan’s energy storage policy is anchored by the Ministry of Economy, Trade and Industry (METI), which outlined its ambitions in the 6th Strategic Energy Plan, adopted in 2021.

Does Japan need battery energy storage?

A Growing Need for Energy Storage The increasing generation of renewables on the Japanese grid has led to various support policies and CAPEX subsidy schemes to support the deployment of grid-scale Battery Energy Storage (BESS).

What is Japan's Strategic Energy Plan?

The Government of Japan formulates the Strategic Energy Plan under the Basic Act on Energy Policy to show the basic directions for Japan’s energy policies. The Advisory Committee for Natural Resources and Energy started discussions on the Seventh Strategic Energy Plan in May 2024 and presented the draft version of the plan on December 17, 2024.

Does Japan's energy storage rollout face structural headwinds?

Despite strong policy signals, Japan’s energy storage rollout faces deep structural headwinds. The nation’s split-grid architecture—50 Hz in the east and 60 Hz in the west—limits electricity transfer and complicates nationwide deployment.

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.

Who is responsible for Japan's Energy Policy?

T he Ministry of Economy, Trade, and Industry (METI): primarily responsible for the evolution of Japan’s energy policy. The Agency for Natural Resources and Energy (ANRE): a department within METI that drafts energy policies. The Electricity and Gas Market Surveillance Commission (EGMSC) provides regulatory oversight.
