Geothermal Gold: Unearthing the Valuation of sustainable ventures

A geothermal power plant is a facility that generates electricity using the Earth’s natural heat. It harnesses the thermal energy stored beneath the Earth’s surface to produce electricity in a sustainable and renewable manner. Geothermal power plants utilize various technologies to extract heat from underground reservoirs of hot water or steam and convert it into electrical energy. Here’s an explanation of the key components and processes involved in a typical geothermal power plant:

1. Geothermal Reservoir: The geothermal reservoir is a subsurface layer of rock containing hot water or steam. It is the primary source of thermal energy for the power plant. Geothermal reservoirs are typically located in regions with volcanic activity, tectonic plate boundaries, or other geological features that allow heat from the Earth’s mantle to rise to the surface.
2. Production Wells: Production wells are drilled into the geothermal reservoir to extract hot water or steam. These wells penetrate deep into the Earth’s crust to reach the reservoir and allow the geothermal fluid to flow to the surface. The number and placement of production wells depend on the size and characteristics of the reservoir.
3. Fluid Collection System: Once extracted from the reservoir, the geothermal fluid is transported to the surface through a fluid collection system. This system may include pipelines, pumps, and other equipment to convey the fluid from the production wells to the surface facilities.
4. Surface Processing Facilities: At the surface, the geothermal fluid undergoes various processing steps to separate the steam from the water and remove any impurities. Depending on the type of geothermal resource (steam or hot water), different processing techniques such as separation, flashing, and scrubbing are employed to prepare the fluid for power generation.
5. Power Generation System: The processed geothermal fluid is used to drive turbines connected to electrical generators, converting the thermal energy into mechanical energy and then into electricity. There are several types of geothermal power generation systems, including dry steam, flash steam, and binary cycle plants, each of which utilizes different technologies to generate electricity from geothermal energy.
6. Transmission and Distribution: The electricity generated by the geothermal power plant is transmitted through power lines to homes, businesses, and other consumers via the electrical grid. It may undergo voltage transformation and other distribution processes to match the requirements of different end-users.
7. Injection Wells (Optional): In some cases, after the thermal energy has been extracted from the geothermal fluid, it may be reinjected back into the reservoir through injection wells. This helps to replenish the reservoir and maintain its pressure, ensuring sustainable long-term operation of the geothermal power plant.

Overall, geothermal power plants provide a reliable and environmentally friendly source of electricity by tapping into the Earth’s natural heat. They play an essential role in diversifying energy sources, reducing greenhouse gas emissions, and promoting energy independence.

Types of Geothermal Plant

There are several types of geothermal power plants, each utilizing different technologies to harness the Earth’s heat for electricity generation. Some common types include:

1. Dry Steam Power Plants: These plants use high-pressure steam from underground reservoirs to drive turbines and generate electricity.
2. Flash Steam Power Plants: Flash steam plants take hot water from underground reservoirs and allow it to “flash” into steam as it rises to the surface. The steam is then used to drive turbines and produce electricity.
3. Binary Cycle Power Plants: In binary cycle plants, hot water or steam from underground reservoirs is passed through a heat exchanger, heating a separate fluid with a lower boiling point (usually an organic compound). This secondary fluid vaporizes and drives turbines to generate electricity.
4. Enhanced Geothermal Systems (EGS): EGS plants utilize technology to create or enhance underground reservoirs by injecting water into hot rocks, stimulating the natural heat exchange process. This method expands the potential locations for geothermal power generation beyond traditional hot spots.

Each type of geothermal power plant has its own advantages, limitations, and suitability depending on the geological characteristics of the site.

Valuation Example:

First of All the production rate of the geothermal plant is estimated. The production rate of a geothermal plant is closely related to several fluid flow properties, including permeability, porosity, and temperature, within the geothermal reservoir. Here’s how each of these factors influences production rate:

1. Permeability: Permeability refers to the ability of a rock formation to transmit fluids through its pore spaces. In geothermal reservoirs, high permeability allows for easier fluid flow and extraction of heat from the reservoir to the production wells. Rocks with higher permeability can sustain higher production rates as they offer less resistance to fluid flow. Conversely, low permeability can restrict fluid movement and reduce production rates.
2. Porosity: Porosity refers to the volume percentage of pore spaces within a rock formation. Higher porosity indicates more space available for fluid storage and movement. Rocks with higher porosity can hold larger volumes of geothermal fluid, which can contribute to higher production rates by providing greater access to heat-bearing fluids. However, porosity alone may not be sufficient if permeability is low, as it affects the ability of fluids to flow through the rock.
3. Temperature: Temperature is a critical factor in geothermal energy production, as it directly influences the amount of heat available for extraction from the reservoir. Higher reservoir temperatures result in higher enthalpy (heat content) of the geothermal fluid, which translates to higher energy production rates. Therefore, geothermal reservoirs with higher temperatures typically have greater potential for higher production rates. However, temperature alone does not guarantee high production rates; permeability and porosity also play crucial roles in fluid flow and heat transfer.
4. Reservoir Depth and Thickness: The depth and thickness of the geothermal reservoir also influence production rates. Deeper reservoirs often have higher temperatures, which can increase the enthalpy of the geothermal fluid and enhance production rates. Thicker reservoirs may contain more geothermal fluid and provide larger contact areas for heat exchange, contributing to higher production rates.
5. Fluid Composition: The chemical composition of the geothermal fluid can impact production rates by affecting fluid properties such as viscosity, density, and corrosiveness. Fluids with high mineral content or dissolved gases may require additional treatment or mitigation measures to prevent scaling, corrosion, or other issues that could affect production rates.

A detailed exploration work is done as explained above and reservoir characteristics are determined. A Computer simulation and scenario analysis is conducted to accurately predict the production rate.

Let us make some assumptions for the valuation of the plant:

Assumptions:

1. Geothermal Resource: The hypothetical geothermal resource has a temperature of 200°C and is located at a depth of 2,000 meters.
2. Power Plant Capacity: We’ll consider a medium-sized binary cycle geothermal power plant with a capacity of 20 megawatts (MW).
3. Cost Estimation: We’ll estimate the CAPEX for plant development, assuming average costs based on industry data.
4. Revenue Projection: We’ll project revenue from electricity sales based on average market prices for renewable energy.
5. Operating Costs: We’ll estimate annual operating costs based on industry benchmarks.
6. Discount Rate: We’ll use a discount rate of 8% to discount future cash flows back to present value.

Revenue Projection:

• To calculate the revenue generated by the power plant, we need to estimate the total amount of electricity sold and the price at which it is sold. Let’s assume that the electricity is sold at an average price of $100 per megawatt-hour (MWh), which is a common rate for electricity in many markets. (A more accurate price assumption can be made through forecasting by taking historical price assumptions)
• Given that the total electricity generated annually is 157,680 MWh, we can calculate the revenue as follows:
• Revenue=Total Electricity Generated (MWh/year)×Price per MWh Revenue=157,680 MWh/year×$100/MWh
• Revenue=$15,768,000 per year
• So, the estimated annual revenue generated by the power plant is $15,768,000.

Fixed Direct Costs:

• Depreciation of Production Equipment: $800,000/year
• Property Taxes on Production Facilities: $250,000/year
• Insurance Premiums for Production Assets: $200,000/year

Variable Costs:

• Fuel Costs: $1,500,000/year
• Labor Costs: $1,000,000/year
• Maintenance and Repair Costs: $400,000/year
• Utilities Costs: $200,000/year
• Chemicals and Consumables: $100,000/year
• Environmental Compliance Costs: $150,000/year
• Operating Supplies: $100,000/year

Fixed Indirect Costs:

• Administrative Salaries and Wages: $500,000/year
• Office Rent and Utilities: $200,000/year
• Professional Services: $150,000/year
• Regulatory Compliance: $100,000/year
• Depreciation of Non-Production Assets: $300,000/year
• Interest Expenses: $400,000/year
• Taxes (Other Than Property Taxes): $200,000/year
• Contingency and Reserves: $300,000/year

Variable Indirect Costs:

• Communication Expenses: $100,000/year
• Training and Development: $100,000/year
• Marketing and Advertising: $200,000/year
• Travel and Entertainment: $100,000/year
• Safety and Security: $200,000/year
• Equipment Maintenance and Repair: $400,000/year

With these revised estimates, the total annual operating costs (OPEX) would be:

Total OPEX=$4,700,000+$3,050,000+$2,200,000+$2,600,000Total OPEX=$4,700,000+$3,050,000+$2,200,000+$2,600,000 Total OPEX=$12,550,000

Total cost per year =$12,550,000

To calculate the profit and free cash flow, we’ll first deduct the total operating expenses (OPEX) from the revenue to find the operating profit. Then, we’ll adjust for taxes, depreciation, and any other relevant expenses to calculate the free cash flow. Let’s proceed with the calculations:

1. Profit before tax:

Profit before tax =Revenue−Total OPEX

=$15,768,000−$12,550,000

=$3,218,000

To calculate the free cash flow (FCF) with annual capital expenditures (CAPEX) included, we need to deduct the CAPEX from the operating profit after taxes and depreciation. Let’s assume an annual CAPEX of $500,000 for this calculation:

1. Profit after Taxes and Depreciation:

Profit after Taxes

=Profit×(1−Tax Rate) = $3,218,000×(1−0.30) =$3,218,000×0.70

Profit after Taxes=$2,252,600

2. Free Cash Flow (FCF):

FCF= Profit after Taxes + Depreciation−CAPEX

FCF=$2,252,600+$800,000−$500,000 = $ 2,552,600

So, with an annual assumption of CAPEX of $500,000, the estimated free cash flow for the power plant is approximately $2,552,600.

To calculate the Discounted Cash Flow (DCF), we need to discount the projected future cash flows (in this case, the free cash flow) to their present value using an appropriate discount rate. The formula for DCF is:

Let us assume:

• Initial investment: $20,000,000
• Discount rate: 10%
• Projection period: 20 years
• Free Cash Flow (FCF) per year: $2,552,600

The Discounted cashflow can be calculated by the following formula:

NPV of the project can be calculated by:

For our case:

• FCFt​ is the cash flow in period t,
• C0​ is the initial investment or cash outflow at time t=0,
• r is the discount rate, and
• n is the number of periods.

For our case:

The Discounted cashflow is: $2,50,61,803.07

NPV of the project is: $50,61,803.07

Conclusion:

In conclusion, the valuation of a geothermal plant involves a comprehensive analysis of various factors, including resource assessments, project feasibility, operating costs, revenue streams, and financial metrics such as Net Present Value (NPV) and Discounted Cash Flow (DCF).
