Japan s shared energy storage policy interpretation meeting

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'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.

What is Japan's 6th Strategic Energy Plan?

According to Japan’s 6th Strategic Energy Plan, battery storage will be increased as a distributed source of electricity closer to end users and within microgrids. This new policy calls for an increase in installed solar capacity from 79 gigawatts (GW) in 2022 to 108 GW by 2030.

How is Japan's energy storage landscape changing?

Japan’s energy storage landscape is shifting, pushed by household demand, corporate ESG mandates, and domestic battery manufacturing. The residential lithium-ion market, projected to grow at a CAGR of 33.9% through 2030, remains one of the fastest-expanding segments.

Is Japan's Energy Policy ambitious?

Japan’s government called the package of energy policies and their targets “ ambitious.” Energy security considerations may affect the progress and pace of decarbonization in the electric power sector.

What are Japan's Energy plans?

Japan’s 6th Strategic Energy Plan (released in 2021) and the GX (Green Transformation) Decarbonization Power Supply Bill (released in 2023) target increasing the share of non-fossil fuel generation sources to 59% of the generation mix by 2030 compared with 31% in 2022.
