One of the six-generation units at Jebba hydroelectric power plant which is located on the Niger River in Kwara State, Nigeria, is set to be rehabilitated by ANDRITZ Hydro, one of the globally leading suppliers of electromechanical equipment and services for hydropower plants, and a division of Andritz AG, which is an Austrian engineering group that provides a comprehensive product portfolio for special industries all over the world.
The Austrian company was selected by Mainstream Energy Solutions Limited, a privately-owned power generating company in the West African country incorporated in 2011 and licensed to operate the Kainji and Jebba Hydroelectric Power Plants through a concession agreement with the Federal Government of Nigeria.
The ANDRITZ scope of supply and services
The Austrian group will supply and install all the electromechanical and hydro-mechanical equipment for unit 2G6, one of the six fixed-blade propeller-type turbines of the Jebba hydroelectric power plant that has been out of order since 2009 following a fire.
The equipment includes a 96.4 MW turbine, a 103 MVA generator, a transformer, an external switchyard, and ancillary equipment, as well as an intake grid.
According to Mainstream Energy Solutions Limited, Andritz is expected to deliver the new unit between late 2023 and early 2024.
The objective of the exercise
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.
The renovated power station will support the electrification process in the country where barely 56.5% of more than 196 million inhabitants have access to electricity according to a 2018 report.
The federal government aims to reach an installed capacity of 30,000 MW by 2030, at least 30% of which will be produced from renewable sources.
