Used for geothermal project feasibility, cash-flow forecasting, and investment analysis; sold as a digital download on Flevy.

Use this model when a developer, sponsor, lender, or investor must assess feasibility, financing, and operational economics for a geothermal power project from exploration through commercial operations.
  Project finance analysts building detailed month-by-month and quarterly cash-flow forecasts and computing LCOE for investment decisions.
  Renewable energy developers compiling development budgets including land, hard/soft costs, and drilling schedules.
  Infrastructure investors modeling LP/GP return splits and promote structures during fundraising.
  Commercial lenders stress-testing DSCR and loan amortization with IO or moratorium periods.
The template’s modular development-to-operations cash-flow roll-up and formal debt scheduling follow standard financial-modeling best-practices for project finance.

A geothermal energy plant generates electricity by harnessing heat from beneath the Earth's surface. It extracts steam or hot water from underground reservoirs to drive turbines connected to generators. The process produces reliable, low-emission power and operates continuously, unlike solar or wind. Geothermal plants are typically located in geologically active areas and offer a sustainable, long-term energy solution with minimal environmental impact.

This Financial model presents a development and operations scenario of a Geothermal Energy Plant covering exploration and drilling costs, plant construction, operating expenses, energy output, and revenue projections. The model supports project feasibility, cash flow forecasting, and investment analysis, with dynamic inputs for resource capacity, tariff structures, and financing options. It provides a robust framework to assess long-term viability and support sustainable energy development.

The structure of the template follows Financial Modeling Best Practices principles and is fully customizable.

Model Structure

•  General Setup & Acquisition Inputs
Production and Operations-related inputs, including Project Timing, Production Assumptions (Generator Capacity, Net Capacity Factor, Capacity to Thermal Potential Ratio, Thermal Resource Degradation), Revenue (PPA Terms and Tarriffs), Operating Expenses, Capital Expenditures, Financing through Equity, Debt, and Government Grants, and Tax Benefits (ITC or Tax Free period)

•  Development Budget
Plant Development Assumptions including Land costs, Hard costs, Soft costs, Development Timing, and Development Cash Flow distribution (Straight-line, S-Curve).

•  Debt Schedule
Loan amortization Schedule of project's debt including an optional moratorium and interest-only (IO) period.

•  Monthly & Quarterly Cash Flows
These 2 reports present all the operating cash flows of the project over monthly and quarterly periods. It allows users to control the timing and how the cash flows over that time.

•  Annual Cash Flow
A roll-up of the monthly cash flows into annual periods from Plant Development to Net Cash Flow after taxes. It includes also calculation of Levelized Cost of Energy (LCOE), and Debt Service Reserves.

•  Performance Reports
The model includes KPIs and Perfomance dashboard reports assisting users to monitor project's operations and profitability.

•  Project Returns
Report presenting project unlevered and levered returns (Pre-Tax & After-Tax IRR, MOIC, Cash Outflows, Inflows and Profits)

•  Investors' Returns Waterfall
A 3-tier IRR hurdle waterfall model to distribute proceeds between investors. The report provides inputs for up to 4 different LPs with different equity contribution percentages and up to 4 different GPs with different equity contributions and equity share percentages. The first tier distributes cash flow to the partners until the LPs has achieved some defined preferred return and received a full return of capital. Assuming the preferred return hurdle is hit in tier one, cash flow is distributed in tiers two and three based on a defined promote structure and hurdle rates as outlined by the user.

•  Project Executive Summary:

A high-level summary of the project's key data, including:
– Key Project Metrics (Project Timing, Production Metrics, Payback Period, LCOE, Free & Clear Return Ratio, Cash-on-Cash Ratio, DSCR)
– Uses & Sources of Cash
– Operations Summary (Revenue, Net Operating Income, Net Cash Flow)
– Project Level Return Metrics (Unlevered & Levered)
– Partnership (LP's & GP's) Level Returns Summary (IRR, MOIC, Cash Outflows, Cash Inflows, Profit)
– Business Performance Dashboard

Detailed instructions for the use of the model are included in the Excel file.

TOPIC FAQ

What key components should a geothermal project finance model include?

A complete geothermal project model should include general setup and acquisition inputs, production and operations assumptions (generator capacity, net capacity factor, thermal degradation), a development budget (land, hard/soft costs), a debt schedule with optional IO/moratorium, monthly/quarterly cash flows, annual cash-flow roll-up, LCOE, and an investors’ returns waterfall such as a 3-tier IRR hurdle waterfall.

How is levelized cost of energy (LCOE) used in geothermal financial models?

LCOE is produced in the annual cash-flow roll-up to compare lifetime project costs versus energy output and revenue. It helps assess long-term viability alongside KPIs and debt-service metrics; Flevy’s Geothermal Energy - Project Finance Model explicitly calculates LCOE in its Annual Cash Flow report.

What is an investors’ returns waterfall and how is it modeled for projects?

An investors’ returns waterfall allocates project proceeds across defined tiers based on IRR hurdles and promote structures. The model supports preferred returns, return of capital, and tiered promotes across multiple partners, and in this template a 3-tier IRR hurdle waterfall with inputs for up to 4 LPs and 4 GPs is provided.

What features should I prioritize when buying a geothermal project finance template?

Prioritize dynamic inputs for resource capacity and tariffs, a development budget module (land, hard/soft costs), detailed Debt Schedule with moratorium/interest-only options, monthly/quarterly cash flows, LCOE and KPI reporting, and investor returns waterfall capability; Flevy’s Geothermal Energy - Project Finance Model includes these core features like Debt Schedule and Monthly & Quarterly Cash Flows.

How much Excel or finance experience is needed to use a geothermal project model?

Models vary,, but this template includes detailed instructions and support aimed at users with differing experience levels; basic Excel competence helps for inputting production, tariff, and financing assumptions, while advanced scenario work benefits from financial-modeling knowledge and the provided instruction set in the Excel file.

Which modeling steps are important when assessing feasibility after exploration confirms a resource?

Key steps are to input production assumptions (capacity, net capacity factor, thermal degradation), build the development budget (capex timing, land, soft costs), set PPA/tariff and revenue assumptions, run monthly/quarterly cash flows to produce annual results, and evaluate LCOE, DSCR, and project returns in the Project Returns report.

How should grants, tax incentives, and financing structure be represented in a project model?

Represent financing through dedicated inputs for equity, debt, and government grants and include tax-benefit assumptions (ITC or tax-free periods) that affect taxable income and cash flow timing. The model adjusts cash flows via the Debt Schedule and dedicated tax-benefit inputs such as ITC or tax-free period entries.

Can project models capture long-term production decline or thermal degradation effects?

Yes, a geothermal model should allow for degradation and capacity factors to reflect evolving output. This template includes production-related inputs like Thermal Resource Degradation, Net Capacity Factor, and Capacity-to-Thermal-Potential ratio to model long-term output changes.
