Low-Voltage Grid-Scale BESS Implementation Process — From Consultation to Commissioning | REVIX JAPAN

Implementing a low-voltage grid-scale BESS typically takes 4 to 6 months, from the initial land information review through construction and grid interconnection to commissioning. REVIX JAPAN supports every step of the process, so even first-time applicants can proceed with confidence.

For First-Timers: Common Questions

Q. Can I apply without preparing anything in advance? A. Yes. Simply start with a free consultation at STEP 1 — REVIX JAPAN will guide you through all the necessary information and documentation. No preparation is required.

Q. Can I withdraw at any point? A. You may cancel without cost at any point before signing the contract (prior to STEP 4). Please feel free to consult us without any obligation.

Step-by-Step Details

STEP 1: Consultation & Land Information Review (Est. 1–2 weeks)

First, contact REVIX JAPAN via the web form or email. Please provide the location, area, current use, and preferred arrangement (land lease or equipment ownership) of the land, and our representative will conduct an initial review.

STEP 2: Preliminary Assessment & Revenue Projection (Est. 1–2 weeks)

Based on the land information provided, we research publicly available data (hazard maps, noise restriction zones, nearby grid infrastructure, etc.) to determine initial feasibility and provide a rough revenue projection (free of charge at this stage).

Key assessment items:

• Hazard risk (flooding, landslides)
• Proximity to connectable low-voltage distribution lines (6,600 V or below)
• Noise restriction zone status
• Agricultural land classification / zoning (whether farmland conversion is required)

STEP 3: Site Visit & Condition Negotiation (Est. 2–4 weeks)

A REVIX JAPAN representative visits the site to conduct a detailed assessment of the installation environment, surroundings, and utility pole locations. Based on the findings, we explain the proposed terms including land lease fees, contract duration, and scope of construction.

STEP 4: Contract Execution (Est. 1–2 weeks)

Upon agreement on terms, the contract is executed. Landowners will sign a land lease agreement; equipment owners will sign an equipment purchase agreement and construction contract.

We explain all contract terms clearly to ensure no questions remain. We may recommend consulting a legal professional for technically complex provisions.

STEP 5: Grid Interconnection Application (Est. 1–3 months)

We submit the grid interconnection application to the local transmission system operator (electric utility). The process from application to receipt of the interconnection approval typically takes 1 to 3 months (subject to the utility's processing schedule).

STEP 6: Engineering, Procurement & Construction (Est. 1–3 months)

Once grid interconnection approval is obtained, we proceed with engineering, procurement, and construction.

Standard scope of work:

• Foundation construction (concrete foundation)
• BESS, EMS, and transformer installation
• Electrical work (service entrance pole, wiring)
• Communication work (EMS connection)
• Fence installation (equipment protection)
• Grid work (utility-side work)

We provide advance notification to neighbors and take appropriate measures to address noise and vibration during construction.

STEP 7: Grid Interconnection & Inspection (Est. 1–2 weeks)

Following construction completion, the utility conducts inspections and confirms the connection, completing grid interconnection.

STEP 8: Market Participation & Commissioning

After grid interconnection, bidding and operations in the frequency regulation market begin. Under coordination with the aggregator, the EMS manages operations automatically. Regular status reports are provided after commissioning.

Important Notes

• Feasibility and revenue levels depend on the land's location, grid conditions, and market environment.
• The time from grid interconnection application to approval may be significantly delayed depending on the utility's processing schedule.
• Agricultural land may require a separate farmland conversion procedure, which can add additional time.
• Details regarding construction costs, lease fees, and revenue are discussed during individual consultations.
