REVIX JAPAN is a company that drives every phase of grid-scale BESS deployment — from low-voltage and high-voltage battery systems to land assessment and sales support, agency program management, and beyond — all under one roof. We deliver proven execution capability to those who want to turn shifts in the power market into real revenue.
Why Grid-Scale BESS Now? The Revenue Opportunity Inside the Power Market
Japan's power grid is at a turning point. The rapid spread of renewable energy — led by solar — combined with an explosive surge in data center demand has created a structural imbalance: power surpluses during the day and shortages in the evening now occur within the same 24-hour period. In the TEPCO service area alone, new data center applications are said to total approximately 7 million kW — the equivalent of six to seven nuclear reactors.
The key to resolving this supply-demand imbalance is grid-scale BESS. By storing electricity and releasing it when needed, batteries help stabilize the grid while generating revenue through participation in three power markets: the frequency regulation market, the capacity market, and the wholesale electricity market (subject to market conditions). REVIX JAPAN advances this socially vital battery business together with landowners, investors, and business partners.
REVIX JAPAN's Three Business Domains
Low-Voltage Grid-Scale BESS (49.9 kW)
A compact grid-scale BESS that can get started with as little as approximately 6 tsubo (about 20 m²) of land. Landowners can expect rental income of around ¥40,000 per month simply by leasing their land (estimated figure; actual amounts vary by conditions), while investors and business partners can deploy it as a power-market revenue business by securing a site. The system comes with a 15-year manufacturer warranty for long-term, stable operation support (warranty terms subject to product specifications).
Best suited for:
- Landowners looking to make use of unused land (6 tsubo or more)
- Investors seeking the next revenue asset after solar
- Those who want to work as an agent or intermediary for low-voltage BESS

High-Voltage Grid-Scale BESS (MW-Class)
A containerized battery system offered by TDS (Tokyo Electric Power Services Co., Ltd.), a TEPCO Group company, and NEXTES Co., Ltd. It features three key differentiators: a KHK-certified fire-resistant enclosure, NEXTES's patented active balancing technology, and JC-STAR ★1 compliant security across all major components. Backed by a 20-year capacity guarantee (70%; per product specifications) and 24/7 remote monitoring, the system supports stable long-term operation. A revenue model combining three markets — the frequency regulation market, the capacity market, and the wholesale electricity market — aims to maximize returns over the long term (subject to market conditions).
Best suited for:
- Corporations and investors considering MW-class grid-scale BESS investment
- Operators who want to shift FIT solar to FIP and boost revenue with co-located battery storage
- EPC and O&M providers looking to take part in high-quality battery projects

Grid Interconnection Site Assessment and Sales Support
For those who hold a grid interconnection connection application reply (接続申込回答書) — or connection study response at the pre-application stage — or grid interconnection rights, we provide a one-stop service covering everything from buy-side assessment to sale support. A free preliminary diagnostic — covering hazard maps, noise regulations, and buried cultural assets based on publicly available information — along with a written assessment report ensures attentive support from the very first step of your sales exploration.
Seeking Agency and Partnership Partners
REVIX JAPAN actively promotes collaboration with sales agents for low-voltage and high-voltage grid-scale BESS, EPC and O&M partners, and aggregators. Through the "REVIX Agency Program (Ribikuro Certification)" we provide a structured education system including product briefings and a weekly schedule of training.

Common Questions & Concerns
-
How much does it cost to get started?
Costs vary by project scale — low-voltage (49.9 kW) vs. MW-class have very different footprints. Landowners can typically participate at no upfront cost via a land-lease model. For investors and operators, we prepare customized project estimates. Please reach out for a no-obligation consultation.
-
Will I need to manage operations myself after installation?
High-voltage systems are supported by 24/7 remote monitoring by REVIX JAPAN. Low-voltage systems also come with regular inspection and operations management packages, keeping the workload on the owner side minimal.
-
How stable is the revenue from the power markets?
Revenue is diversified across the frequency regulation market, capacity market, and wholesale market. Because market prices fluctuate, we cannot guarantee specific earnings. REVIX JAPAN provides individual revenue simulations based on current market conditions so you can clearly understand the risk-return profile before committing.
-
What if my situation changes — can I exit or adjust?
Options depend on your contract and business structure. We explain exit strategies and risk scenarios thoroughly at the consultation stage. Start with a free materials request or consultation.
