Building a 450 MW hydropower plant is a monumental undertaking that requires massive capital and a solid long-term economic case. The Mamfe Hydropower Project has been structured as a Build-Operate-Transfer (BOT) concession, a public-private partnership model that leverages international expertise and private finance while guaranteeing national ownership after a fixed period.

Project Cost and Financing Structure
The total cost of a major infrastructure project of this scale includes construction, the power transmission line, and all associated social and environmental mitigation programs.
1. Total Estimated Cost
Based on comparable projects in the region, such as the 420 MW Nachtigal Hydropower Plant in Cameroon (costing approximately €1.2 billion or CFA 786 billion), the estimated capital expenditure for the 450 MW Mamfe project is projected to be in the range of €1.1 billion to €1.3 billion (approximately CFA 720 billion to CFA 850 billion).
2. Funding Sources: The BOT Model
The BOT model is designed to minimize the upfront fiscal burden on the Government of Cameroon (GoC) by attracting a consortium of private investors and international financiers.
Funding Component Typical Structure Key Actors/Examples
Equity Investment (25-30%) Capital provided by the private project consortium (the developer). Joule Africa, EDF (Electricité de France), African Infrastructure Funds, and the Government of Cameroon (holding a significant minority stake).
Debt Financing (70-75%) Long-term loans mobilized from international and local sources. Multilateral Development Banks (World Bank/IFC, African Development Bank), Bilateral Agencies (EIB, AFD), and Commercial Banks.
Risk Mitigation Guarantees to make the project “bankable” for commercial lenders. World Bank Partial Risk Guarantee (PRG) to cover risks like payment default by the national utility (the off-taker).
The Economic Case and Financial Returns
The project’s financial viability is secured by a long-term Power Purchase Agreement (PPA), typically lasting 20 to 35 years, between the project company and the national utility.(the off-taker).
1. Return on Investment (ROI)
The Private Investor View: Private investors and lenders in BOT projects expect a competitive internal rate of return (IRR) to compensate for the political and commercial risks inherent in developing countries. The reliable, long-term revenue stream from the PPA guarantees the repayment of debt and a return on the equity investment over the concession period.
The Government View (BOT Transfer): After the concession period, the ownership of the fully operational and debt-free power plant will be transferred to the Government of Cameroon. This ensures a valuable, long-term national asset that will generate electricity at a significantly lower operating cost for decades to come.
2. Macroeconomic Benefits for Cameroon
The Mamfe Project’s primary justification is its transformative impact on the national economy, aligning with Cameroon’s Vision 2035 goal of becoming an emerging economy.
Economic Benefit Description Impact
Increased Generation Capacity The 450 MW will boost Cameroon’s current installed capacity by an estimated 30-35%. Reduces load shedding and ensures a reliable power supply for households and industry.
Lower Cost of Electricity Hydropower provides the least-cost source of base-load power compared to thermal/diesel plants. Saves millions of dollars annually on fuel imports and lowers the overall cost of electricity, making it more affordable for consumers and businesses.
Industrial Stimulation Reliable, affordable electricity is a precondition for industrial growth. Attracts new foreign direct investment and allows existing local industries (like aluminum and manufacturing) to operate at full capacity.
Job Creation The project will create thousands of jobs during the 5-7 year construction phase and provide stable, skilled jobs for the 35-year operational phase. Stimulates local economies and builds national technical capacity.
In conclusion, the Mamfe Hydropower Project is a strategically sound investment. It is financially robust, attracting necessary private capital, and economically vital, securing Cameroon’s energy future with affordable, clean power to drive industrialization and poverty reduction.
