1. Executive Summary

Geodyn Solutions proposes the development of a 300 MW advanced hydroelectric power plant in the Dominican Republic to deliver clean, reliable energy at a rate of 17 cents per kWh, leveraging the country’s significant hydroelectric potential, estimated at 623 MW of installed capacity as of 2020 (Global Energy Monitor). This project aligns with the Dominican Republic’s goal of achieving 25% renewable energy by 2025, reducing reliance on imported fossil fuels, which account for over 80% of electricity generation (Energy Profile). The estimated project cost, including a 20% contingency fee to account for risks such as geological challenges, is $1.65 billion to $2.5 billion. The project is expected to yield a return on investment (ROI) of approximately 178% over 30 years, with the initial investment recovered in about 11 years. The plant is anticipated to create 1,500–3,000 temporary jobs during construction and 50–100 permanent jobs during operation, stimulating local economies in regions like the Yaque del Norte River basin. Environmentally, the plant could offset 1 million metric tons of CO2 annually, supporting the country’s commitment to reduce greenhouse gas emissions by 27% by 2030, though careful mitigation of ecological impacts is essential.

2. Project Background

The Dominican Republic, located on the island of Hispaniola, has significant hydroelectric potential due to its mountainous terrain and river systems, such as the Yaque del Norte and Yuna rivers. As of 2020, hydroelectric power accounted for approximately 12.66% of the country’s total installed electrical capacity of 4,921 MW, equating to about 623 MW (Global Energy Monitor). The country’s electricity sector is dominated by fossil fuels (75.39% in 2020), with renewables, including hydroelectric, wind, solar, and biofuels, contributing 24.61% (Global Energy Monitor). The government aims to increase renewable energy to 25% by 2025, supported by the Renewable Energy Incentives Law (57-07), which offers tariff exemptions on imported equipment (Renewable Energy Incentives). This 300 MW hydroelectric power plant will significantly boost the country’s renewable energy capacity, providing reliable baseload power to the national grid and supporting regions with high hydroelectric potential.

3. Project Description

The 300 MW hydroelectric power plant will utilize state-of-the-art technology, including high-efficiency Kaplan or Francis turbines and advanced control systems, to maximize energy output and minimize environmental impact. The plant will generate electricity by harnessing water flow through a dam or run-of-river system, depending on the selected site. Key features include:

• Capacity: 300 MW, sufficient to power approximately 200,000 households.
• Technology: High-efficiency turbines optimized for variable flow conditions.
• Infrastructure: Dam or diversion structure, powerhouse, transmission lines, and access roads.
• Location: To be determined, with potential sites in the Yaque del Norte or Yuna River basins, pending feasibility studies.

4. Cost Estimate

The estimated cost to construct a 300 MW hydroelectric power plant in 2024 ranges from $1.65 billion to $2.5 billion, including a 20% contingency fee. This estimate is based on industry data from sources such as the National Renewable Energy Laboratory (NREL) and Statista, which report costs per kilowatt ranging from $5,500 to $8,611 (NREL Hydropower 2024, Statista 2022).

Cost Breakdown

Cost Factors

• Site Conditions: Costs increase for remote locations or sites with low water head, requiring extensive civil works.
• Inflation: Costs may rise from 2022 estimates due to inflation, with 2024 projections factoring in a 5–10% increase.
• Regulatory Requirements: Permitting and environmental compliance can add 5–10% to costs, particularly in the Dominican Republic, where environmental regulations are stringent.

5. Return on Investment (ROI)

With an electricity rate of 17 cents per kWh, the annual revenue is projected to be approximately $223.38 million, based on an annual energy production of 1.314 billion kWh (300 MW × 8,760 hours × 0.5 capacity factor). Operational costs are estimated at $31.13 million per year (1.5% of the $2.075 billion CAPEX midpoint), resulting in an annual net cash flow of $192.25 million. The payback period is approximately 11 years, and over a 30-year lifespan, the project is expected to generate a total net profit of $3.69 billion, yielding an ROI of approximately 178% on the initial investment.

ROI Calculation

• Annual Revenue: $223.38 million (1.314 billion kWh × $0.17/kWh)
• Annual OPEX: $31.13 million (1.5% of $2.075 billion CAPEX midpoint)
• Annual Net Cash Flow: $223.38 million – $31.13 million = $192.25 million
• Payback Period: $2.075 billion / $192.25 million ≈ 10.8 years (rounded to 11 years)
• Total Revenue (30 years): $223.38 million × 30 = $6.7 billion
• Total OPEX (30 years): $31.13 million × 30 = $933.9 million
• Total Costs: $2.075 billion (CAPEX) + $933.9 million (OPEX) = $3.009 billion
• Net Profit: $6.7 billion – $3.009 billion = $3.691 billion
• ROI: ($3.691 billion / $2.075 billion) × 100% ≈ 178%

ROI Sensitivity Analysis

Financial Considerations

• Revenue Stability: Hydropower’s baseload capability ensures consistent revenue, unlike intermittent renewables like solar or wind (Geothermal Advantages).
• Incentives: The Renewable Energy Incentives Law (57-07) offers a 100% tariff exemption on imported equipment, reducing CAPEX. Tax exemptions on profits may still apply, enhancing profitability (Renewable Energy Incentives).
• Risks: Market volatility, regulatory changes, or operational risks like droughts could impact ROI. Mitigation includes securing long-term power purchase agreements (PPAs) and leveraging funding from institutions like the Inter-American Development Bank (IDB Funding).

6. Job Creation

The project is expected to create significant employment opportunities:

• Construction Phase (3–5 years): 1,500–3,000 temporary jobs, including:
  • Civil engineers and construction workers for dam and infrastructure development.
  • Electrical engineers for turbine and grid integration.
  • Support staff for logistics, safety, and administration.
• Operational Phase: 50–100 permanent jobs, including:
  • Plant operators and maintenance technicians.
  • Environmental monitoring specialists.
  • Administrative and management personnel.

These estimates are based on industry norms for hydropower projects of similar scale. Local hiring will be prioritized, with training programs to enhance workforce skills, particularly in regions like the Yaque del Norte River basin.
