Project finance documentation forms the contractual backbone of every infrastructure deal. Whether you’re structuring a power plant, toll road, or infrastructure PPP, understanding how contracts allocate risks, define responsibilities, and protect lender interests is essential. This guide covers everything you need to know — from Project Agreements to loan documentation.

Before diving into contracts, it helps to understand the fundamentals of project finance and how deals are structured across different sectors.

Project Agreement Structure

The Project Agreement is the cornerstone contract that defines the revenue stream for the entire transaction. It establishes what the project will deliver, how it will be paid, and what happens when things go wrong. Three main models dominate project finance:

Offtake Contract (Power Purchase Agreement)

In process-plant projects like power stations, the Offtake Contract — commonly called a Power Purchase Agreement (PPA) — defines the sale of the project’s output to a creditworthy buyer. The classic structure involves:

• Capacity Charge — Covers fixed costs, debt service, and equity return. Paid whenever the plant is available, whether or not it is dispatched. The Offtaker carries dispatch risk.
• Energy Charge — Covers variable costs, primarily fuel. Passed through based on actual output.

Offtake variants include Take-or-Pay (buyer must pay even if it doesn’t take delivery), Take-and-Pay (pay only for what is taken — weaker protection), Tolling (buyer supplies the input, pays a processing fee), and Contract for Differences (merchant sales with price guarantees).

Concession Agreement

In Concessions, the Project Company provides a public service and collects user charges directly — think toll roads, airports, or ports. The Contracting Authority grants the right to build and operate, but revenue depends on usage rather than a guaranteed payment stream. This introduces demand risk that must be carefully analyzed and mitigated.

Availability-Based Contract (PFI Model)

In availability-based contracts, common in social infrastructure like hospitals and schools, the Contracting Authority pays for the asset being made available to the required standard. Payment is tied to availability and performance metrics, not usage. This model transfers construction and maintenance risk while keeping demand risk with the public sector.

Construction and Operating Contracts

Lenders require “one-stop” responsibility for construction: a single contractor who takes full accountability for delivering the project on time, on budget, and to specification. This is achieved through the EPC Contract.

EPC Contract Structure

The Engineering, Procurement, and Construction (EPC) contract — also called a turnkey contract — wraps all construction risk into a single fixed-price, date-certain agreement. The EPC contractor “wraps” its subcontractors and takes responsibility for their performance. This adds roughly a 20% price premium over cost-plus arrangements, but provides the certainty lenders require.

Completion occurs in stages:

1. Mechanical Completion — All equipment installed and ready for testing
2. Substantial Completion — Project meets performance guarantees; handover to Project Company
3. Final Completion — Punch list items resolved; defects liability period begins

Liquidated Damages

The EPC contract includes Liquidated Damages (LDs) — pre-agreed compensation for delays or underperformance:

O&M Contract

The Operations and Maintenance (O&M) contract governs operation of the completed project. Fee structures typically follow one of two models:

• Fixed + Indexed — Common for maintenance; transfers lifecycle cost risk away from the Project Company
• Cost-Plus — Common for process-plant operations; Project Company retains cost risk but gains flexibility

O&M contractors face performance incentives and penalties, but LD caps are typically limited to 1-2 years of fees — far less than EPC exposure.

Direct Agreements and Step-In Rights

In non-recourse project finance, lenders cannot pursue sponsor assets if the project fails. Their protection comes from Direct Agreements — tripartite contracts between the lenders, the Project Company, and each key counterparty.

Key Protections

Direct Agreements typically provide:

• Acknowledgment of security — Counterparty confirms the lenders’ security interests
• Notice of default — Lenders receive notification if the Project Company breaches the underlying contract
• Cure periods — Time for lenders to remedy defaults before the counterparty can terminate
• Step-in rights — Lenders can appoint a nominee to operate the project in place of the Project Company
• Substitution rights — Lenders can replace the Project Company entirely with a new entity
• No amendment without consent — Material changes to underlying contracts require lender approval

Cure Period Structure

Security Package

The security package gives lenders control over the project’s assets, contracts, and cash flows. But unlike traditional corporate lending, foreclosure on physical assets is rarely a realistic remedy in project finance — the value lies in the contracts and the cash flows they generate, not the steel and concrete.

Security typically operates across four layers, working together with the SPV structure:

Layer 1: Cash Flow Control

Project Accounts under lender control ensure revenues flow through a predetermined “waterfall” — operating costs first, then debt service, then reserves, then distributions to equity. Dual-signature requirements prevent unauthorized withdrawals.

Layer 2: Step-In Rights

As discussed above, Direct Agreements provide the mechanism for lenders to take operational control before problems become terminal.

Layer 3: Asset and Contract Security

Traditional charges and assignments over:

• Site, buildings, and equipment (mortgages)
• Project Contracts and their receivables (assignments)
• Insurance policies and proceeds
• Permits and licenses (where assignable)
• Hedging contracts (swap receivables)

Layer 4: Share Security

Security over the Project Company’s shares allows lenders to sell the entire SPV to a new buyer — often the cleanest exit in a workout scenario.

Loan Documentation

The loan documentation governs the relationship between the Project Company and its lenders. Project finance loan agreements are far more extensive than standard corporate facilities because lenders have no recourse beyond the project itself.

Conditions Precedent

Conditions Precedent (CPs) are the checklist that must be satisfied before Financial Close — often running to hundreds of documents:

• Corporate: Board resolutions, legal opinions, constitutional documents
• Project: Signed Project Contracts, Notice to Proceed, all permits in place
• Financing: Loan agreements executed, security perfected, accounts opened
• Due diligence: Technical advisor reports, Model Auditor sign-off, legal opinions

Covenants

Loan covenants in project finance are far more extensive than in corporate lending:

Events of Default

Events of Default (EODs) trigger lender remedies — but they are triggers, not automatic terminations. Lenders can waive defaults, impose conditions, or ultimately accelerate the debt and enforce security.

Common EODs include:

• Payment default (typically 2-3 business day grace period)
• Breach of financial covenants (e.g., DSCR falling below minimums)
• Project Contract default or termination
• Abandonment or total loss
• Material Adverse Change (MAC)
• Insolvency or cross-default

Intercreditor Agreement

When multiple lender groups participate (senior debt, mezzanine, export credit agencies), the Intercreditor Agreement governs their relationship — voting rights, waterfall priorities, enforcement rights, and standstill periods. Majority voting thresholds (typically 66.7-75%) prevent a single lender from blocking necessary waivers or workouts.

EPC vs EPCM Contracts

While EPC is the standard for project finance, EPCM (Engineering, Procurement, and Construction Management) is sometimes used where turnkey contracting is impractical — notably in mining, oil and gas, and projects with owner-furnished equipment.

EPCM is harder to finance because lenders cannot point to a single creditworthy party responsible for completion. Sponsors using EPCM typically provide completion guarantees or accept higher equity requirements.

Common Mistakes

Project finance documentation is complex, and several common errors can undermine deal viability:

1. Misaligned Contract Terms — The Project Agreement, EPC contract, and O&M contract must be “back-to-back” — risks passed down from the revenue contract must flow through to the construction and operating contracts. Misalignment creates gaps where the Project Company bears risks it cannot pass on.

2. Insufficient LD Caps — Delay LDs must cover debt service during the delay period (typically 6+ months). If LD caps are exhausted before the project is complete, lenders have no contractual protection — only the sponsor’s goodwill.

3. Missing Direct Agreements — Every material counterparty needs a Direct Agreement. A missing tripartite with the O&M operator or fuel supplier can leave lenders unable to step in when they need to most.

4. Confusing Commercial and Financial Close — Sponsors sometimes believe the deal is “done” at Commercial Close. But Financial Close — when CPs are satisfied and funds can flow — is what matters. Delays between the two can strand projects.

Limitations of Project Finance Documentation

While comprehensive documentation provides substantial protection, it cannot eliminate all risks:

1. Enforcement Uncertainty — Local law governs enforcement of security, and some jurisdictions have slow or unpredictable court systems. Offshore structures help but don’t eliminate local-law risks.

2. Political and Regulatory Risk — Contracts with government entities are subject to sovereign immunity, regulatory changes, and political interference that documentation alone cannot prevent. These commercial and political risks require separate mitigation strategies beyond contract drafting.

3. Relationship vs. Documentation — In distressed situations, outcomes often depend more on stakeholder relationships and workout negotiations than on strict contractual rights. A well-drafted contract is necessary but not sufficient.

4. Complexity Costs — Extensive documentation adds transaction costs, extends timelines, and creates operational burden. The cost-benefit varies by deal size — what makes sense for a $500 million project may be overkill for $50 million.

5. Changed Circumstances — Long-term contracts cannot anticipate every scenario. Material Adverse Change clauses and renegotiation mechanisms are imperfect tools for handling genuinely unforeseen developments.
