Project Finance Models Built for Debt Sizing, Investment Decisions and Lender Underwriting

Financely develops and reviews renewable energy project finance models for sponsors, developers, investors and asset owners preparing projects for debt financing, equity investment, refinancing or financial close.

Our work is built around the economics that determine whether a project can support institutional capital: generation, contracted and merchant revenue, operating costs, capex, taxes, debt service, reserves, DSCR, leverage, sensitivities and investor returns.

Why the Model Matters

A project finance model is the numerical credit case.

Renewable energy projects are financed from future project cash flows. The financial model therefore has to demonstrate how those cash flows behave before, during and after debt service.

A technically attractive project can still fail lender underwriting if the debt sizing is unsupported, operating assumptions are inconsistent, the revenue case is overstated or the model cannot explain what happens under downside scenarios.

The model should reconcile the project's commercial agreements with its financing structure. That includes the EPC contract, equipment cost, generation assumptions, PPA or offtake terms, merchant exposure, operating expenses, degradation, taxes, working capital, reserves and debt terms.

For projects being prepared for project finance debt and capital placement , the model becomes one of the core documents used to determine leverage, repayment capacity and lender appetite.

Debt Size the Facility Determine sustainable debt based on DSCR, tenor, interest, amortization and cash available for debt service.
Revenue Model the Operating Case Translate generation, pricing, contracted revenue and merchant exposure into project-level cash flow.
Risk Stress the Downside Measure the effect of lower generation, higher costs, delays, degradation, curtailment and financing changes.
Returns Calculate Equity Economics Measure project IRR, equity IRR, distributions, payback and residual value after financing.

Model Scope

What a renewable energy project finance model should contain.

Sources & Uses

EPC cost, development expenditure, financing costs, reserves, contingency, taxes, sponsor equity and debt funding.

Construction Period

Monthly or quarterly draw schedule, sponsor equity funding, debt drawdowns, interest during construction and commercial operation timing.

Generation

Installed capacity, production assumptions, degradation, availability, losses, curtailment and P50/P90 production cases where applicable.

Revenue

PPA revenue, capacity payments, merchant power prices, renewable-energy certificates, ancillary services and other contracted income.

Operating Costs

O&M, land lease, insurance, asset management, grid charges, maintenance, replacement capex and other recurring expenses.

Debt Schedule

Drawdowns, benchmark rate, margin, fees, grace period, repayment profile, debt sculpting, maturity and outstanding balance.

Debt Service

Interest, principal, DSCR, LLCR, PLCR and cash available for debt service.

Reserve Accounts

Debt service reserve account, major-maintenance reserve, working-capital reserve and other lender-required liquidity accounts.

Tax

Depreciation, taxable income, corporate tax, withholding assumptions and project-specific fiscal considerations where relevant.

Equity Returns

Equity contributions, distributions, cash yield, project IRR, equity IRR, MOIC and exit or residual-value assumptions.

Debt Sizing

The lender case begins with cash available for debt service.

Maximum debt is rarely determined by project cost alone. Project lenders size facilities by combining leverage limits with cash-flow coverage and downside constraints.

DSCR Period-by-period cash available for debt service relative to scheduled principal and interest.
LLCR Present value of cash available for debt service during the loan life relative to outstanding debt.
PLCR Present value of project cash flows over the economic project life relative to debt.
Leverage Debt relative to total project cost, sponsor equity and lender risk appetite.
Tenor Repayment period calibrated to contract term, asset life and refinancing risk.
Sculpting Principal repayments structured around projected project cash flow and target coverage ratios.
Sensitivity Analysis

A bankable model has to show what happens when the base case is wrong.

Renewable-energy underwriting is heavily dependent on assumptions that can change during development, construction and operation. Sensitivity analysis makes those risks visible before a lender's credit committee does.

Sensitivity Typical Stress Primary Impact
Generation P50, P75, P90 or project-specific downside production case. Revenue, DSCR, debt capacity and investor returns.
Construction Cost EPC or development capex above budget. Equity requirement, leverage and completion funding.
COD Delay Commercial operation occurs later than planned. IDC, liquidity, PPA timing and debt maturity.
Power Price Lower merchant price or reduced post-PPA price assumption. Cash flow, coverage and terminal value.
Operating Cost Higher O&M, insurance, land or grid costs. CFADS and debt-service headroom.
Interest Rate Higher benchmark rate or lender margin. Debt service and maximum sustainable leverage.
Degradation Production declines faster than assumed. Long-term revenue and refinancing capacity.
Curtailment Higher grid-related production losses. Generation, revenues and DSCR.
Model Review

Existing models can be audited, rebuilt or prepared for financing.

Not every engagement begins with a blank spreadsheet. Sponsors frequently already have an internal development model that was built to evaluate project economics rather than satisfy institutional lenders.

Financely can review the existing workbook, identify structural weaknesses, rebuild the financing modules and prepare a cleaner lender-facing version.

Audit

Formula and Logic Review

Review formulas, circularity, links, timing conventions, accounting logic and inconsistencies across the workbook.

Restructure

Improve Model Architecture

Separate assumptions, calculations, financial statements, debt schedules, sensitivities and outputs into a transparent model structure.

Debt

Add Lender Mechanics

Build drawdowns, IDC, interest, amortization, DSCR, reserve accounts and debt-sculpting mechanics.

Sensitivity

Build Downside Cases

Add generation, price, capex, delay, operating-cost, interest-rate and other project-specific sensitivities.

Deliverables

What the modeling engagement can produce.

01

Financing Preparation

The model can be built as part of a wider project finance process.

Financial modeling can be commissioned as a standalone engagement or used as part of a broader financing mandate.

Projects that have reached an appropriate stage can subsequently move into Financely's project finance facilitation process, where the model supports structuring, lender selection, underwriting and execution.

Solar developers can also review our commercial solar project finance capabilities for debt and capital requirements beyond the financial model.

Transactions requiring more than senior debt may also be evaluated through Financely's full capital stack placement capabilities.

FAQ

Renewable Energy Project Finance Modeling FAQ

What is a renewable energy project finance model?

It is an integrated financial model that converts technical, commercial and financing assumptions into projected project cash flow, debt-service capacity and investor returns.

Can you build a model from scratch?

Yes. The model can be developed from the project's available technical, commercial, cost and financing assumptions.

Can you review an existing model?

Yes. Existing sponsor or developer models can be reviewed for formula integrity, model architecture, debt mechanics, lender ratios, sensitivities and financing-readiness.

Can the model include debt sculpting?

Yes. Debt repayments can be sculpted around project cash flow and agreed target coverage ratios, subject to the proposed lender terms.

Can you model P50 and P90 production cases?

Yes, where appropriate technical production assumptions are available. Multiple production and revenue cases can be incorporated into the model.

Can battery storage be included?

Yes. Battery models can incorporate capex, charging and discharge, cycling, efficiency, degradation, augmentation, contracted revenue, merchant revenue and associated financing assumptions.

Can the model be used with lenders?

The model can be prepared for lender and investor review, but each financing institution may apply its own assumptions, model audit requirements and underwriting methodology.
