A total 1.67GW of projects won contracts, including 32 battery energy storage system (BESS) totalling 1.1GW and three pumped hydro energy storage (PHES) projects totalling 577MW.
Listed below are the five largest energy storage projects by capacity in Japan, according to GlobalData''s power database. GlobalData uses proprietary data and analytics to provide a complete picture of the global energy storage segment.

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).
By 2030, official estimates show variable renewable energy reaching 20% of Japan''''s power mix. Noting the demand case and ever-growing renewables curtailment numbers nationwide, more and more firms are tapping into Japan''''s battery storage opportunities.
In Japan, they kind of do—thanks to pumped storage power stations. These engineering marvels are critical for balancing the country''s energy grid, especially as it shifts toward renewable sources like solar and wind.
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.

As part of its efforts to achieve its goals of energy transition and liberalizing electricity market structures, Japan hopes to become one of the most promising grid-scale energy storage markets in the Asia-Pacific region.

With renewable energy accounting for 38% of the national grid (up from 22% in 2020), the island nation faces mounting pressure to stabilize its power supply. But how exactly does energy storage fit into this puzzle?...
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).
Global energy storage capacity was estimated to have reached 36,735MW by the end of 2022 and is forecasted to grow to 353,880MW by 2030. Japan had 1,671MW of capacity in 2022 and this is expected to rise to 10,074MW by 2030. Listed below are the five largest energy storage projects by capacity in Japan, according to GlobalData’s power database.
In the next few decades, Japan will mainly use solar energy Electricity from power generation facilities and wind power facilities. And it expects oil and LNG prices to fall as a result.
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.
In March 2023, Japan announced a power grid expansion master plan, which is expected to invest 6 trillion to 7 trillion yen (45 billion to 55 billion U.S. dollars) by 2050. In the next few decades, Japan will mainly use solar energy Electricity from power generation facilities and wind power facilities.
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.
