Wärtsilä has been awarded a ten-year operations and maintenance (O&M) contract from Lafarge Cement WAPCO to operate the 100MW cement plant power station in Nigeria.

Under the contract, Wärtsilä will operate and maintain all parts of the on-site power station, covering scheduled and unscheduled maintenance, spare parts, labour, technical support, administration, human resource services and training, logistics management and security.

The plant, located near the city of Ewekoro, will provide electricity to a new cement works under construction.

Six Wärtsilä 18V50DF engines that can run on light fuel oil, heavy fuel oil or gas will be used to power the turnkey project, the company said.

The Ewekoro power plant along with other plants delivered by Wärtsilä will bring the overall generating capacity provided by the company to Nigeria to 400Mwe.

The power plant is expected to be in full commercial operation in January 2011.

The expansion project will enable Lafarge to satisfy local cement demand in Nigeria, as the company increases capacity from two million tonnes to more than four million tonnes of cement generated by 2011.
