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).
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 , remains one of the fastest-expanding segments.
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 .
Is Japan a good market for grid-scale storage?
With strong ambitions towards the energy transition and a liberalised power market structure, Japan is one of the most promising markets for grid-scale storage in Asia Pacific. The country’s electricity consumption per capita is twice the Asia Pacific average, and there is a race to keep up.
How big is Japan's battery storage market?
In the commercial space, Japan’s battery storage market was valued at USD 593.2 million in and is projected to reach USD 4.15 billion by . While commercial installations currently dominate revenues, industrial adoption is expected to scale faster. Utility-scale storage is also gaining ground.
Who manages the electricity market in Japan?
These are: The Japan Electric Power Exchange (JEPX): manages the wholesale market. The Organisation for Cross-regional Coordination of Transmission Operators (OCCTO): coordinates electricity supply and demand plans, manages interconnectors, and runs the capacity market.
