Mainstream Energy names ANDRITZ to modernize unit at 578.4-MW Jebba hydro plant

ANDRITZ reports it has received an order from Mainstream Energy Solutions Limited to modernize one generation unit at the 578.4-MW Jebba hydro plant on the Niger River in Nigeria.

Mainstream Energy Solutions Limited is a privately owned power generating company incorporated in 2011 and licensed to operate the 750-MW Kainji and Jebba hydroelectric power plants through a concession agreement with the Federal Government of Nigeria. The contract has a value of more than €30 million (US$36.4 million), and commissioning is planned for end of 2023 and beginning of 2024.

The Jebba Hydroelectric Power Plant is located in Niger State and was commissioned in 1985. It is 100 km downstream of the Kainji plant and equipped with six 96.4-MW fixed-blade propeller-type turbines, resulting in a total installed capacity of 578.4 MW. Five of the units are available for generation, while the sixth is out of operation due to a major fire incident in April 2009. The new equipment will repower the plant and boost the energy production of Nigeria.

The ANDRITZ scope of supply and services comprises the entire electromechanical and hydromechanical equipment for unit 2G6, including a turbine, a 103-MVA generator, transformer, outdoor switchyard and accessory equipment, and the intake gate.

The objectives of the general rehabilitation program are to extend 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.

ANDRITZ offers a broad portfolio of plants, equipment, systems and services for the pulp and paper industry, the hydropower sector, the metals processing and forming industry, pumps, solid/liquid separation in the municipal and industrial sectors, as well as animal feed and biomass pelleting. ANDRITZ Hydro supplies electromechanical equipment and services for hydropower plants, with an installed fleet of more than 430 GW.
