PROJECT DESCRIPTION
The 700MW Zungeru Hydro-Electric Power Project is located on the Kaduna River in the State of Niger, approximately 150km at crow flight North West of Abuja, the Federal Capital of the Republic of Nigeria.
It is designed to generate 2,630 GWh energy at reservoir FSL 230 and flow rate of 880m3/sec, total installed capacity of 700MW with a plant factor of 0.33. The main features of the Project include, a composite dam with a roller compacted concrete dam (RCC), rock-fill dams, diversion work, spillway and plunge pool, power intake and penstocks, hydroelectric power plant, tail race channel, switchyards and 330/132KV transmission lines evacuating power to the existing grid connecting Jebba and Shiroro 330kV power plants and Tegina 132KV Substation respectively.
The main hydraulic structures (gated spillway, power intake and diversion galleries) are integrated into the RCC dam structure on the left bank. A temporary service bridge will be built downstream of the dam for construction purpose.
The hydroelectric power plant consists of four Francis turbine units operating at net nominal head of 92m, nominal flow of 220cu.m/sec and rated speed of 107.1rpm.
