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).

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).

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.
