Mambilla is a proposed 3,050 MW hydropower complex on the Donga River in Taraba State, Nigeria. The scheme comprises multiple dams, underground powerhouses and twelve generating units and is intended to become a major source of renewable baseload electricity for Nigeria and neighbouring markets.
Federal Government records describe Mambilla as a long-standing strategic power project and historically reported agreement of an EPC contract and Chinese financing support. Those announcements provide official historical context but do not, by themselves, establish current contractor mobilisation or physical construction.
The project will develop a 3.05 GW hydroelectric complex near Kakara Village on the Mambilla Plateau in Taraba State. The approved PAP II concept includes four dams on the Donga River, water-conveyance tunnels and canals, two underground powerhouses and twelve turbine-generator units. The plant is designed to produce approximately 5.46 billion kWh of electricity each year. The high natural head and river flows of the Mambilla Plateau will be used to provide large-scale renewable generation for the Nigerian grid and potential regional exports.
Verified implementation and technical context: The scheme is one of Nigeria's largest proposed infrastructure investments and would require construction of multiple dams and reservoirs, underground waterways and powerhouses, high-head generating equipment, access infrastructure, transmission evacuation and major environmental and social management measures on the Mambilla Plateau. Federal budget and presidential records have repeatedly identified the project as a national priority and allocated funds for counterpart requirements, consultancy and implementation preparation. Because the official announcements are historical and the project has experienced a prolonged development period, the database description should distinguish the approved technical scope from any claim that the full EPC works are presently mobilised.
1. Increase Nigeria's electricity generation capacity by 3,050 MW to improve national grid stability and access, representing approximately a 30% increase in current generation capacity. 2. Generate approximately 5.457 billion kWh of renewable electricity annually to meet growing domestic demand. 3. Stimulate economic growth and industrial development in Taraba State, the broader region, and nationally. 4. Create up to 50,000 temporary and permanent local jobs during the construction phase. 5. Increase power supply for potential export to neighboring countries including Niger, Togo, Benin, and Chad via the West African Power Pool. 6. Contribute to Nigeria's energy transition goals and Vision 30:30:30 (30 GW capacity, 30% renewables by 2030) by providing a major source of clean, baseload hydroelectric power. 7. Help Nigeria achieve a 90% electricity access rate by 2030. 8. Support flood control, irrigation for food security, and tourism development in Taraba and Benue states.
