Andritz to modernise unit at Jebba plant, Nigeria

21 January 2021

Andritz has been contracted to modernise one generation unit at the 578.4MW Jebba hydroelectric power plant on the Niger River.

The Jebba plant is located in Niger State, in the north-central part of Nigeria and was commissioned in 1985. It is situated 100km downstream of the Kainji hydroelectric plant and is equipped with six fixed blade propeller type turbines with a generating capacity of 96.4MW each. 

Five of the units at the plant are available for generation while the sixth is out of operation as a result of a major fire which occurred in April 2009. The new equipment will repower the plant, boost the energy production of Nigeria and provide much needed energy to the people of the country.

Andritz’s scope of supply and services comprises the entire electro-mechanical and hydro-mechanical equipment for unit 2G6 including a 96.4MW turbine, a 103 MVA generator, transformer, outdoor switchyard and accessory equipment, as well as the intake gate.

The objectives of the general rehabilitation program are an extension of equipment service life for the next 40 years, improving the reliability, and ensuring compliance of the frequency and voltage regulation with the national grid code.

Valued at more than €30 million, the contract has been awarded by Mainstream Energy Solutions Limited – a privately owned power generating company in Nigeria incorporated in 2011 and licensed to operate the Kainji and Jebba Hydroelectric Power Plants through a concession agreement with the Federal Government of Nigeria. Commissioning is planned for end of 2023/ beginning of 2024.
