Jebba Hydroelectric Plant Station

The Jebba Hydroelectric Plant Station is located jebba town Kwara state. However, some schools of thought say it is between Niger and Kwara State in jebba dam across the Niger River in Nigeria. The closest city, Mokwa, is about 40 kilometres southwest of the Jebba Power Station, which is situated around 100 kilometres downstream of the Kainji Dam. This is roughly 256 km southwest of Minna, the Niger State capital, via road. Situated on the banks of the Niger River, marking the boundary between Niger and Kwara states, the power station is roughly 91.5 kilometres away by road northeast of Kwara state’s capital, Ilorin. It has a power generating capacity of 578.4 megawatts. The plant started commercial energy production in 1983 but was commissioned in 1983.

Overview of Jebba Hydroelectric Plant Station

The Federal Government of Nigeria owns the Jebba hydroelectric plant station, which has six generation turbines with a combined rated capacity of 96.4 megawatts, for a total installed output of 578.4 megawatts. As of January 2021, five of the generating units are in service. Due to damage caused by a fire in April 2009, the sixth generation unit is not now operational. The Shiroro Gorge dam on the Kaduna River, west of Bida in Niger state, started operating in 1990. The dam and hydroelectric power plant at Jebba, which is located 64 miles (103 km) from the Kainji Dam, were finished in 1984. Jebba is one of Nigeria’s three largest dams, situated in the state of Niger. The other two are Shiroro Dam, constructed in 1990, and Kainji Dam, constructed in 1968. At Zungeru, in Niger State, a fourth dam is being constructed. These are all hydroelectric dams with a 1,900 megawatt maximum combined power output. Mainstream Energy chose the Austrian technical company Andritz AG in January 2021 to fix the malfunctioning turbine and bring the power plant back up to par. The electrical-mechanical tasks comprise the following: (a) swapping out the 96.4 megawatt turbine; and (b) setting up a brand-new 103MVA generator. (c) setting up a new transformer; (d) setting up a new outdoor switchyard; and (e) changing out the intake gate and other auxiliary equipment. Mainstream Energy Solutions Limited, an independent power business, holds the concession agreement for operations and maintenance at this power plant. Additionally, the 760 megawatt Kainji Hydroelectric Power Station, which is situated roughly 100 km upstream of Jebba Power Station, is concessioned to Mainstream Energy.

Capacity of Jebba Hydroelectric Plant Station

It has six turbines and six turbine-alternator groups, each with a producing capacity of 96.4 MW for a net head and 102 MW at maximum output, for a total installed capacity of 578.4 MW. It is located 100 km downstream of the Kainji Hydroelectric Power Plant. While the sixth unit is not in service as a result of a significant fire that happened in April 2009, the other five units are ready for generation. The project is going strong right now. It has undergone several stages of development. After construction was finished, the project was put into service in 1983.

Jebba Dam

The Jebba Dam is situated between Kwara State and Niger. It is located 236 feet (71.917 metres) above mean sea level. The dam is made of rockfill and soil, and it is connected to other infrastructure and auxiliary dams. An upstream blanket ensures the imperviousness of the main dam, which is situated to the south. A lock and roughly three auxiliary concrete dams come next. There is a spillway and the powerhouse with water inflow located in between these auxiliary dams. The auxiliary dam 1 and emergency reinforced spillway are made of the same kind of dike as the main dam. A secondary valley is sealed off by a saddle dam of the same design as the main dam. The operational level is typically 103.0 metres. A run-of-river project is Jebba. 3,900 million cubic metres is the capacity of the hydro reservoir. The project has a net head of 27.6 metres. There are six penstocks, or lengthy pipes or channels that transport water from the hydroelectric reservoir to the power station’s turbines. Ten metres is the penstock diameter. The Dam is made up of the civil dam structures, the hydroelectric powerhouse with generators and turbines, a navigation lock, and associated M&E and monitoring systems. Together, they form a continuous structure with a crest length of almost 2,000 metres.
