Jun 27, 2025 · UK BESS investor Gore Street Capital has acquired its first asset in Japan through what it claims is the country''s first dedicated energy storage fund. The acquisition was made
Jul 1, 2022 · Currently, Photovoltaic (PV) generation systems and battery energy storage systems (BESS) encourage interest globally due to the shortage of fossil fuels and environmental
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.
These are the Ministry of Economy, Trade, and Industry (METI) and the Tokyo prefectural subsidies. There are a series of requirements to be eligible: projects must have a minimum capacity of 1 MW, the battery must be able to participate in various markets, and the battery must be directly connected to the grid. The Market for Energy Storage
In the earlier round held in 2024, it won contracts for four BESS projects totaling 131 MW. Combined with the current round, the company now holds a portfolio of nine BESS projects in Japan with a total capacity of 479 MW. The awarded BESS projects are now in late-stage planning.
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.
Stonepeak and CHC’s energy storage platform will develop five new battery storage projects in Japan. These projects have a combined capacity of 348 megawatts (MW). The deals were finalized under Japan’s Long-term Decarbonization Auction. These projects were selected as part of Japan’s latest long-term auction focused on low-carbon energy.
Sun Village said then that it was targeting the deployment of 250 BESS projects across Japan, each 2MW/8MWh and totalling 500MW/2,000MWh. By 2026, the Asia-Pacific region is forecast to contribute 68% of the projected $10.84 billion market.
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.
