Alstom Hydro China (AHC) was awarded a contract worth about US$78 million by China National Electric Engineering Co., Ltd. to provide electro-mechanical equipment and technical services for the US$1.3 billion 700-MW Zungeru hydroelectric project on the middle and upper reaches of the Kaduna River near Zungeru, Niger, Nigeria.
According to the contract, AHC will provide four 175 MW Francis turbine-generator sets and related equipment for this project. AHC is responsible for the equipment design, manufacture, installation supervision, commission, tests and additional site services.
Zungeru hydropower project is Nigeria’s largest hydropower plant under construction.
The project will provide power generation, flood protection and water for irrigation. It includes a roller-concrete compacted dam (90 meters in height and 1,090 meters in length), an intake tower and diversion tunnel, underground powerhouse, power transmission lines and access roads.
Officials hope the Zungeru plant will help alleviate the country’s massive energy deficit, where blackouts are a near daily occurrence and much of the population relies on diesel generators.
Zungeru is one of several hydro projects that are part of Nigeria’s Renewable Energy Master Plan (REMP) proposed in 2006. REMP seeks to increase the supply of renewable electricity – including wind, solar, biomass and small hydro – from 13% of total electricity generation in 2015 to 23% in 2025 and 36% by 2030, according to the Nigerian government.
According to Alstom, AHC is Alstom’s largest hydropower industrial site worldwide and during the past 20 years it has accumulated a 20% market share of the total Chinese installed capacity of large hydro equipment.
