Andritz to modernise second generating unit at the Jebba hydropower plant in Nigeria

Jebba hydroelectric power plant on the Niger River (Mainstream Energy Solutions Limited).

Andritz has received an order from Mainstream Energy Solutions Limited for the modernisation of another generating unit at the Jebba hydroelectric power plant on the Niger River. This contract follows an order received in January last year to modernise the first unit 2G6.

The Andritz scope of supply and services comprises the entire electro-mechanical and hydro-mechanical equipment for unit 2G5, including a 96.4MW turbine, a 103MVA generator and accessory equipment, as well as the intake gate.

Originally commissioned in 1985, the Jebba hydroelectric power plant is located in the North Central zone of Nigeria, about 100km downstream of the Kainji Hydroelectric Power plant. It is equipped with six 96.4MW turbines and has a total generating capacity of 578.4MW.

The objectives of the general rehabilitation programme are to extend the equipment service life for the next four decades, improve reliability, and ensure compliance of the frequency and voltage control with the national grid code. The new equipment will repower the plant, improve the energy production of Nigeria, and provide much-needed energy to the people of the country.

The commissioning of the second generating unit has been scheduled for beginning of 2024.
