Since hydroelectricity is produced using natural water pressure, it is a clean, renewable energy source that might play a significant role in Nigeria’s overall energy production. As of now, Nigeria has 2,378 MW worth of hydroelectric capacity, which accounts for about 5% of the country’s total capacity.
A recent article in Daily Trust said that three sizable hydroelectric dams can be found in the state of Niger in Nigeria. In 1968, the Kainji Dam was built, then in 1985 the Jebba Dam, and finally in 1990 the Shiroro Dam. Another dam in Niger State is being built at Zungeru. All told, these hydroelectric dams have the potential to generate 1,900 megawatts of electricity.
The Kainji Dam in Niger State is the country’s first and oldest hydroelectric project. It began operations in 1968 and has a total capacity of 760 MW. The dam, located on the Niger River, contains both the Kainji Hydroelectric Power Plant and the Jebba Hydroelectric Power Station.
According to power.gov.ng, the Shiroro Dam in Niger State was officially opened in 1990. The dam on the Kaduna River may generate up to 600 megawatts of power. The Shiroro Hydroelectric Power Station is operated at the dam site by the Niger Delta Power Holding Company.
The Jebba Dam is located between the states of Kwara and Niger. The Jebba dam is built with earth and rockfill and is linked to a network of auxiliary dams and support facilities.
The power plant consists of six turbines and six groups of turbine-alternators. The maximum output for each of the propeller turbines is 102 MW, while their net head ratings are both 96.4 MW. The total nominal installed capacity is 578 MW.
The Niger State is home to the Zungeru Dam construction site. The dam, with an installed capacity of 700 MW, will be located on the Niger River. The Niger Delta Power Holding Corporation plans to operate the Zungeru Hydroelectric Power Station at the project site.
