By securing a site and installing and operating a low-voltage grid-scale BESS (49.9 kW), you can generate business revenue centered on standby compensation from the frequency regulation market (e.g., estimated annual revenue of approximately ¥480,000; actual amounts vary by conditions). Whether you see it as the next revenue asset after solar, or an entirely new investment destination, join REVIX JAPAN in building a power-market-participating BESS business.
Participation Models for Investors and Business Partners
Model 1: Secure a Site and Build from the Ground Up
You independently acquire land eligible for a grid interconnection feasibility study response or connection application reply and install low-voltage grid-scale BESS on it. REVIX JAPAN supports the entire process — from site sourcing through grid interconnection application, equipment installation, and market entry.
Model 2: Replace or Co-Locate with an FIT Solar Plant
Add battery storage to — or replace — a solar power plant whose FIT period has ended or is about to end. Because you can leverage existing power connection rights, the grid interconnection process may proceed more smoothly in some cases.
Model 3: Develop Projects as an Agent or Intermediary
You can also participate as a partner who introduces or brokers landowners and site information to us. For details on the REVIX Agency Program (Ribikuro Certification), please see the Agency Program page.
Revenue Model Overview
Revenue from low-voltage grid-scale BESS comes primarily from participation in the frequency regulation market.
Primary Revenue Source: Frequency Regulation Market
The frequency regulation market is a market through which the TSO procures the "balancing services" needed to maintain supply-demand balance on the power grid. Simply by keeping the battery "on standby and ready to charge or discharge at any time," ΔkW (standby compensation) accrues.
Key Features of Standby Compensation (ΔkW Value)
- Compensation is generated even if charge/discharge is never actually dispatched
- Bids are submitted the day before; operation runs in 30-minute blocks
- Primary frequency response (offline) allows participation without a dedicated communication line
Reference Estimates
| Item | Reference Estimate |
|---|---|
| Estimated Annual Revenue | ~¥480,000/year (conditions apply) |
| Equipment Cost (Reference) | ~¥22 million (including installation; varies by conditions) |
| Warranty Period | 15 years |
The figures above are reference estimates only. Actual results vary significantly depending on market prices, bid award status, utilization rate, and contract conditions. These figures do not guarantee any specific level of revenue.
[Reference] Simple Payback Period Estimate (varies significantly by conditions) | Item | Reference Figure | |---|---| | Equipment Cost (Reference) | ~¥22 million | | Annual Revenue (Reference) | ~¥480,000 | | Simple Payback Period (Reference) | ~46 years (*) |
The simple payback period is a rough estimate of "equipment cost ÷ annual revenue" and does not include O&M costs, tax treatment, or financing conditions. Revenue from the frequency regulation market fluctuates significantly depending on market unit prices and bid award rates. Please base any actual investment decision on a detailed revenue simulation.

Support We Provide to Investors and Business Partners
1. Site Development & Grid Interconnection Support
We support everything from identifying candidate sites likely to receive a grid interconnection feasibility study response to filing the interconnection application with the utility.
2. System Design & Installation
We handle design, procurement, and construction of the 49.9 kW / 100 kWh system on a one-stop basis, including fencing, foundation, electrical, and communications work.
3. Market Entry & Aggregator Coordination
Bidding and operation in the frequency regulation market are carried out in coordination with an aggregator. EMS-based automated control minimizes the day-to-day operational burden.
4. 15-Year Long-Term Maintenance
Maintenance support including periodic inspections and fault response under the 15-year warranty (details subject to contract terms).
Scaling Up with Multiple Units
After confirming revenue performance with a single unit, you can build a portfolio-style BESS business by expanding to multiple sites. REVIX JAPAN supports the parallel management of multiple projects and tailors its support structure to your business scale.
We can also propose a roadmap toward high-voltage grid-scale BESS (MW-class) deployment.
