Overview

In the rapidly expanding energy storage market, shovel-ready battery projects are prime assets. A recent acquisition by a Melbourne-based developer highlights the value of strategically located, grid-connected storage—in this case, on a state border. This tutorial walks you through the process of evaluating and acquiring such a project, using due diligence, financial modeling, and permitting checks. You'll learn how to spot opportunities, assess readiness, and execute a successful acquisition.

Prerequisites

Knowledge & Resources

• Basic understanding of utility-scale battery energy storage systems (BESS)
• Familiarity with electricity markets and grid interconnection (e.g., NEM in Australia)
• Access to GIS mapping tools or site selection software
• Spreadsheet for financial modeling (NPV, IRR)
• Legal and regulatory checklists for project acquisition

Step-by-Step Instructions

1. Scouting Strategic Locations

The target project sits on a state border, offering arbitrage between two regulatory regimes and access to multiple transmission corridors. To replicate this:

1. Identify regions with high renewable penetration and transmission congestion.
2. Use GIS to overlay existing substations, land zonings, and population centers.
3. Prioritize sites near interconnectors or border zones (like the Victoria-NSW border in Australia).
4. Engage with local network service providers for constraint data.

2. Assessing Shovel-Readiness

A "shovel-ready" project has completed most pre-construction steps. Check for:

• Approved environmental impact assessment
• Signed land lease or option agreement
• Grid connection offer (e.g., connection application accepted or conditional approval)
• Preliminary engineering and design (single-line diagrams, site layout)
• Equipment reservations or supply agreements (transformers, batteries)

Example due diligence checklist (excerpt):

Checklist Item               Status
EIA submitted               ✔
Grid connection AIP          ✔
Land lease 20-year term     ✔
Battery supply MOU          Pending

3. Project Valuation and Financing

Use discounted cash flow (DCF) to estimate value. Assumptions:

• Capacity: 100 MW / 200 MWh (2-hour)
• Revenue: 70% from FCAS, 30% from energy arbitrage
• Construction cost: $350/kWh, financed 70%/30% debt/equity
• WACC: 8%, useful life 20 years

Sample DCF table:

Year  Net CF ($m)   PV Factor   PV ($m)
1     -35.0         0.9259      -32.41
2     5.2           0.8573       4.46
...    ...          ...          ...
20     5.2           0.2145       1.12
NPV = $12.3m, IRR = 11.5%

4. Acquisition Due Diligence

Verify the seller's claims. Key areas:

• Technical: Confirm grid capacity, site geotech, noise constraints.
• Legal: Check title, encumbrances, termination clauses in leases.
• Regulatory: Ensure all state and local permits transferable.
• Commercial: Audit any existing PPA or off-take agreements.

5. Permitting and Timeline Management

Even shovel-ready projects need final permits. Common steps:

1. Submit building permit applications as soon as possible.
2. Schedule for local council compliance (e.g., noise, traffic).
3. Initiate grid connection testing and commissioning plan.
4. Set milestone dates for financial close, notice to proceed, and COD.

Common Mistakes

• Overlooking network constraints: A strategic location can be worthless if the local substation is weak. Always get a system impact study.
• Ignoring community opposition: Even with permits, neighbor complaints can delay construction. Budget for engagement.
• Underestimating construction costs: Shovel-ready does not mean cheap. Secure fixed-price EPC contracts early.
• Missing curtailment risks: Batteries on borders may face overlapping congestion. Model five-year historical curtailment data.

Summary

Acquiring a shovel-ready battery project—like the one on the state border—requires strategic site selection, rigorous due diligence, and careful financial modeling. By following these steps, you can replicate the success of Melbourne-based developers and build a valuable energy storage portfolio. Start with location, verify readiness, then close the deal.
