Where is kainji dam in nigeria

The saddle dam protects the main dam during flooding. There are four spillways with hydraulic operated gates of Kainji Dam is The civil structure for the four turbines is in place. What is mind boggling is the turbine selection and use of a combination of different types of turbine design with varying output and efficiency. The Kaplan and propeller turbines are reaction turbines that need low hydraulic speed to operate, need more maintenance power and have relatively low efficiency.

The over forty years old plant has inadvertently outlived its usefulness. Due to the surge in population growth and the corresponding demand for power, the Kainji dam and the other hydroelectric dams urgently need to be rehabilitated and upgraded to improve their power generation capacity. Therefore, Kaiji hydroelectric power station may be better off by replacing the lower output Kaplan reciprocating turbines with a set of megawatts Francis turbines that would increase its power generation output from megawatts 2, megawatts.

This potential should be investigated further to see how the dam can be moved further in the area of optimal performance. Work is underway to rehabilitate the dam but then, such work should be looking into upgrading the turbines and balance of plant, BOP at the power station.

The additional output combined with a sound upstream water quota agreement together with a good reservoir management practices should guarantee an uninterrupted supply of base load into the national grid. Lighting up Nigeria. Kainji Hydro Power Plant History. All rights reserved. Some power is sold to the neighbouring country of Niger. Preparation work for the scheme saw engineers strengthen bridges and roads along routes totalling 1,km so that heavy machinery and other equipment could be moved to the construction site.

Kainji is a gravity dam. A gravity dam primarily uses the weight of the dam alone to hold back the water pushing against the structure. It was mainly constructed from concrete. Engineers used over , tons of cement and more than 25, tons of steel to build the structure. The cement came from Nigerian companies and from Norway — shipped in specially designed bulk carrier vessels.

Around 50, people were displaced by the scheme. Resettlement work saw villages and 2 new townships built, as well as perimeter roads around the reservoir. The successful completion of this project on schedule… is symbolic of a breakthrough in our consciousness of what can be done for the development of our country.

Nigerian head of state, speaking at the opening of the Kainji dam, At 50 years old, Kainji is the oldest functioning power plant in Nigeria. Kainji is one of 3 major dams in Niger state. The others are the Jebba dam and the Shiroro dam A fourth dam is currently under construction at Zungeru. The park is home to a wide range of wildlife including baboons, duikers a type of antelope , hippopotami, hyenas and warthogs.
