Infrastructure and Energy Transactions
Executive Summary
Key Takeaways
- ✓ A secondary-market acquisition of an operating infrastructure, renewable, or PPP asset is a transaction model built on top of an already-operating asset, distinct from the construction-stage financing model used to originally fund the asset's development.
- ✓ Valuation and debt sizing should be based on the asset's remaining concession, PPA, or contract life, not a full-life projection, since a secondary buyer is acquiring only the years of cash flow remaining under the existing arrangement.
- ✓ The asset's actual operating track record — historical availability, actual versus projected output, realized maintenance costs — should directly inform the acquisition model's forward assumptions, rather than defaulting back to the original construction-stage projections.
- ✓ Existing project lender consent is frequently a condition of a secondary-market transaction, since many project finance facilities restrict a change in sponsor ownership without lender approval, and this consent process should be tracked as an explicit closing condition, not assumed to be a formality.
- ✓ A transaction may be structured as an acquisition of the asset alongside its existing debt, an acquisition with full refinancing, or a hybrid, and this decision has direct modelling consequences for the debt sizing, covenant, and pricing mechanics the acquisition model must represent.
Objective¶
This guide covers the transaction-specific mechanics of a secondary-market acquisition of an operating infrastructure, renewable energy, or PPP asset, within M&A and Transaction Due Diligence. It builds on, rather than repeats, the construction-stage modelling discipline already covered on Financial Model Audit for Project Finance and the existing Concession Model and PPP Model glossary pages.
What Is Distinct About a Secondary-Market Transaction¶
| Dimension | Construction-Stage Financing Model | Secondary-Market Acquisition Model |
|---|---|---|
| Cash flow basis | Full projected asset life from financial close | Remaining concession, PPA, or contract life only |
| Track record available | None — entirely projection-based | Actual historical operating performance |
| Debt sizing basis | Projected construction and operating cash flow | Demonstrated operating cash flow, remaining contract term |
| Existing lender involvement | The original financing lender | Existing lender consent frequently required for ownership change |
Valuing Remaining Contract Life¶
A secondary buyer acquires only the cash flows remaining under the asset's existing concession, power purchase agreement, or contract term — not a fresh, full-life asset. Valuation and any new or refinanced debt sizing should be explicitly based on this remaining term, since using the original full asset life would overstate what the buyer is actually entitled to receive under the existing arrangement. See Demand Risk Model for the underlying revenue risk profile this remaining-term valuation depends on, where the asset carries demand risk rather than a fixed availability or capacity payment.
Using Actual Operating Track Record¶
An operating asset's actual historical performance — availability, actual versus originally projected output, realized maintenance costs — should directly inform the acquisition model's forward assumptions, rather than defaulting back to the original construction-stage projections. A demonstrated track record is a materially stronger evidentiary basis than a pre-construction forecast, and an acquisition model that ignores it in favor of stale original projections forgoes the single most valuable piece of information a secondary buyer actually has access to.
Existing Lender Consent¶
Many project finance facilities include change-of-control provisions restricting a shift in sponsor ownership without lender approval, making existing lender consent a frequent, sometimes binding, condition to closing a secondary-market transaction. This consent process should be tracked explicitly as a closing condition — similar to the treatment described in Buy-Side Due Diligence — rather than assumed to be a formality, since a delayed or denied consent can materially affect transaction timing or structure.
Existing Debt: Assume, Refinance, or Hybrid¶
A secondary transaction can be structured to assume the asset's existing debt facility (subject to lender consent), fully refinance into a new facility, or combine both approaches. Each option carries direct modelling consequences — assumed debt retains its existing covenant package and pricing, while refinanced debt is sized and priced fresh against the asset's now-demonstrated track record — and the acquisition model should represent the actual chosen structure explicitly rather than a generic assumption. See the existing Refinancing Model and Refinancing Gain Sharing glossary pages for the underlying refinancing mechanics this decision draws on.
Structural Checks Specific to Infrastructure and Energy Transactions¶
| Check | What It Catches |
|---|---|
| Valuation and debt sizing are based on remaining, not full original, concession/PPA/contract life | An overstated valuation or oversized debt facility relative to actual remaining entitlement |
| Forward operating assumptions are informed by actual historical track record, not stale original projections | An acquisition model ignoring the asset's own demonstrated performance in favor of outdated forecasts |
| Existing lender consent status is explicitly tracked as a closing condition | A transaction structure invalidated or delayed by an unanticipated consent requirement |
| The existing-debt treatment (assumed, refinanced, or hybrid) is explicitly and consistently reflected throughout the model | A debt sizing or covenant calculation inconsistent with the actual chosen transaction structure |

Frequently Asked Questions
How does a secondary-market infrastructure acquisition model differ from a construction-stage project finance model?
It is built on top of an already-operating asset with an established track record, rather than a pre-construction projection — valuation and debt sizing are based on the asset's remaining concession, PPA, or contract life, and forward assumptions should be informed by actual historical operating performance rather than the original construction-stage forecast.
Why does remaining contract life matter more than total asset life in this context?
Because a secondary buyer is acquiring only the cash flows remaining under the existing concession, power purchase agreement, or contract term, not a fresh full-life asset — valuing or sizing debt against a full original asset life would overstate what the buyer is actually entitled to receive.
How should the asset's operating track record inform the acquisition model?
Directly — historical availability, actual versus originally projected output, and realized maintenance costs should inform the forward assumptions used in the acquisition model, rather than defaulting back to the original construction-stage projections, which may no longer reflect the asset's actual demonstrated performance.
Why is existing lender consent a common transaction condition?
Because many project finance facilities include change-of-control provisions restricting a shift in sponsor ownership without lender approval, making existing lender consent a frequent, and sometimes binding, condition to closing a secondary-market transaction — this should be tracked explicitly, not assumed to be a mere formality.
What are the main options for handling existing debt in a secondary transaction?
Acquiring the asset alongside its existing debt facility (subject to lender consent), acquiring the asset with full refinancing into a new facility, or a hybrid combining partial assumption and partial refinancing — each has direct modelling consequences for debt sizing, covenant structure, and pricing that the acquisition model must represent explicitly.

M&A and Transaction Due Diligence
Transaction due diligence is the structured process by which a party to a proposed transaction — most often a buyer, but also a seller preparing for sale or a lender financing the deal — investigates a target business before committing capital. It is organized into distinct workstreams (financial, commercial, operational, technical, legal, tax, ESG), run from one of three process postures (buy-side, sell-side, or vendor), and its findings feed directly into the financial model used to price the transaction and support the investment decision. This page is the hub for the Knowledge Centre's transaction due diligence content: what due diligence is, how each workstream and process posture differs, and how model risk specifically enters a transaction — the angle this platform is built to address in depth.
What Is a Project Finance Model Audit?
A project finance model audit is a financial model audit applied to the specific class of model used to finance infrastructure, energy, and long dated capital projects: debt sculpted, multi decade, cash flow driven structures with mechanics that do not appear in a typical corporate model. It is frequently a formal condition of financial close, not an optional check, and lender requirements for it exist almost entirely inside non public bank credit policy rather than any single consolidated public source. This page defines what makes project finance models structurally distinct, why lenders require independent verification of them specifically, and what the audit process looks like in this context.
Refinancing Model
A refinancing model is a financial model built to analyse the economics of replacing existing debt with new debt under revised terms. In a project finance or infrastructure context, a refinancing replaces the original construction-phase or early-operational-phase debt with new debt that reflects the reduced risk profile of an operating asset — typically at a lower margin, a longer tenor, or a higher principal amount, or some combination of these. A refinancing model runs the project's financial projections under the proposed new debt terms, calculates the revised DSCR, LLCR, and equity returns, and compares these against the original financing to quantify the benefit of the refinancing.
Refinancing Gain Sharing
Refinancing gain sharing is a contractual mechanism, specified in some project finance financing documents, that splits the incremental value released by a refinancing, typically additional debt proceeds beyond the amount required to repay the original facility, or the value of a reduced financing cost, between the project sponsors and, in some structures, the original lenders. It reflects the fact that a project's reduced risk profile at refinancing, and therefore its increased refinancing capacity, is attributable at least partly to the original lenders' financing of the higher-risk construction and early operating phases.
Concession Model
A concession model is a financial model built for a public-private partnership in which a private concessionaire receives the contractual right to develop, operate, and earn revenues from a public infrastructure asset for a defined concession period, in exchange for meeting specified performance and availability standards. The financial model projects the concessionaire's revenues (from either availability payments, user charges, or a combination), operating and maintenance costs, capital expenditure, financing costs, and returns to equity investors over the concession period.
PPP Model
A PPP model (Public-Private Partnership model) is a financial model purpose-built to analyse the economics of a project structured as a public-private partnership. A PPP is a long-term contractual arrangement between a government authority and a private entity in which the private party designs, builds, finances, and/or operates a public asset or service in exchange for a defined payment stream over a concession period. The PPP model reflects the specific structural features that distinguish PPP transactions from standard commercial financing: - A defined concession period (typically 20 to 35 years or more) - A payment mechanism that is availability-based, demand-based, or a combination - Performance deduction regimes that reduce payment when the facility fails to meet defined standards - Lifecycle obligations requiring the private party to maintain the asset to a defined condition throughout the concession - Termination provisions specifying the compensation payable on early contract termination - A handback obligation returning the asset to the government at concession end
Demand Risk Model
A demand risk model is a financial model for a project finance concession in which the concessionaire's revenue is derived from user charges (tolls, fares, or fees) paid by users of the asset. The concessionaire's revenue therefore depends directly on actual demand for the asset's services, rather than on contractual availability payments from the public authority. Demand risk models are used for toll roads, airports, ports, urban transit systems, and other infrastructure assets where users pay directly for the service. The key risk in a demand risk model is that actual usage may be materially lower than projected, reducing revenue below debt service requirements.
