Geothermal Energy
Financial Model

What are the primary revenue streams?

Your revenue is driven by five distinct streams, starting with electricity sales from 200,000 MWh at $75/MWh in 2026. This is supplemented by selling Renewable Energy Credits (RECs), capacity availability payments, carbon offsets, and, starting in year two, direct geothermal heat sales. This diversified approach provides multiple income sources, with total revenue projected to grow from around $25.8 million in 2026 to over $96.7 million by 2030 as capacity doubles.

Core Revenue Drivers

• Electricity Sales (MWh)
• Renewable Energy Credits (RECs)
• Capacity Availability Payments
• Carbon Offset Units

What is the project's profitability outlook?

The project is projected to be profitable from its first month of operation in January 2026. With strong initial revenue and managed costs, the model shows a first-year EBITDA of $20.45 million. Profitability scales significantly as operations expand, with EBITDA forecasted to reach $82.45 million by 2030. This strong trajectory is driven by high-margin electricity sales and the addition of complementary revenue streams over the five-year period.

Improving Profitability

• Secure long-term, fixed-price power purchase agreements
• Optimize wellfield maintenance to reduce operating costs
• Maximize REC and carbon offset sales in premium markets

How much initial capital is required?

You'll need approximately $32.55 million in initial capital to get this project off the ground. This covers all major upfront costs, from initial geological surveys and land acquisition to well drilling and power plant engineering. The largest single expense is the $15 million for initial well drilling and testing, which is critical for establishing the geothermal resource. This investment analysis of geothermal power generation is defintely a capital-intensive venture.

Major Capital Expenses

• Initial Well Drilling & Testing: $15,000,000
• Geological Survey & Exploration: $5,000,000
• Heavy Equipment Purchase: $4,000,000
• Power Plant Design & Engineering: $3,000,000

What are the project's cash flow dynamics?

Due to the heavy upfront capital investment, the project will experience a significant cash trough before revenues stabilize. The financial model shows your minimum cash balance hitting negative $18.95 million in September 2026. This highlights the importance of securing sufficient initial funding to cover the development phase. The model's detailed monthly cash flow statement allows you to anticipate this gap and ensure you have the necessary capital lined up to bridge it.

Avoiding Cash Flow Gaps

• Secure project financing before starting major construction
• Negotiate milestone-based payments with contractors
• Establish a contingency fund for unexpected delays or costs

What is the expected return on investment?

Investors can expect solid, long-term returns from this project. The model calculates an Internal Rate of Return (IRR), a key metric for energy project valuation, of 8% and a Return on Equity (ROE) of 241.73%. The initial investment is paid back within 21 months, which is quite rapid for an infrastructure project of this scale. These metrics demonstrate a financially viable project that generates significant value over its operational life.

Key Investor Metrics

• Internal Rate of Return (IRR): 8%
• Return on Equity (ROE): 241.73%
• Payback Period: 21 Months
• 5-Year EBITDA: $82.45 million

When does the project reach break-even?

The project is structured to hit its break-even point almost immediately, achieving it in January 2026, just one month after operations begin. This rapid path to break-even is possible because major revenues from electricity sales and capacity payments are assumed to start as soon as the plant is commissioned. The model's break-even analysis pinpoints this milestone, providing a clear target for the initial operational phase.

Accelerating Break-Even

• Pre-sell capacity through Power Purchase Agreements (PPAs)
• Secure upfront payments for RECs or carbon offsets
• Phase capital expenditures to align with revenue generation

How does the model handle stress testing?

This geothermal financial model excel template is designed for robust scenario planning. You can easily adjust key assumptions to see how changes impact your bottom line. For instance, a 10% drop in the electricity price to $67.50/MWh would reduce Year 1 revenue by $1.5 million. Similarly, a 20% overrun on drilling costs would increase your initial funding need by $3 million. This flexibility is essential for understanding risks and building a resilient financial plan.

Common Scenarios to Test

• Fluctuations in electricity and REC prices
• Delays in construction timelines and permit approvals
• Higher-than-expected operational and maintenance costs
• Changes in interest rates for project financing

This geothermal financial model excel template is 100% unlocked and customizable, so you can adapt it to your specific project's needs. We've built in the core assumptions, but you have full control to change revenue streams, cost structures, and financing to match your geothermal energy business plan financial section. This saves you hundreds of hours building from scratch.
