The BESS will more than double Japan’s utility-scale lithium-ion battery capacity, and increase national energy storage capacity in megawatt hours by 220%. To be developed at a cost of 91 billion yen (USD 600 million) over a six-year period, construction on the BESS is expected to begin in 2026.
Once live the BESS will be capable of storing enough electricity to power approximately 63,000 households for four hours 1. Project financing has been arranged by MUFG Bank representing the first battery storage project they have arranged finance for in Japan.
To be developed at a cost of 91 billion yen (USD 600 million) over a six-year period, construction on the BESS is expected to begin in 2026. The planned project does not require any specific financial commitment from Gurīn Energy investor Infratil Ltd.
Project financing has been arranged by MUFG Bank representing the first battery storage project they have arranged finance for in Japan. Under the offtake agreement, Eku Energy will own the BESS while Tokyo Gas will own 100% of its operating rights for 20 years, with Eku Energy responsible for the ongoing maintenance of the facility.
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).
The country aims to achieve 36-38% renewable energy in its energy mix by 2030, supported by 10GW of energy storage by 2030. Gurīn Energy is considering a number of locations and conducting an assessment to finalise a site for BESS development in either Fukushima or Tochigi prefecture.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
