Nigeria: Finland-based Wärtsilä has extended its operation and maintenance agreement with Lafarge Africa by another five years. The agreement covers the 100MW Ewekoro power plant, which provides a dedicated supply of electricity to the company’s concrete and cement manufacturing processes. The extension of the deal was signed in July 2021 and it follows a previous 10-year agreement. The scope of the agreement includes the operating crew, performance guarantees, plant availability and spare parts.

The captive Ewekoro plant was supplied and commissioned by Wärtsilä in 2011. It consists of six Wärtsilä 50DF dual-fuel engines, operating primarily on gas, but with the flexibility to automatically switch to liquid fuel in case of a disruption to the gas supply. The engines are also designed to function efficiently with a low-pressure gas supply, a necessity given the region’s vulnerability to supply interruptions.

“We have benefited significantly from the efficient way by which Wärtsilä has operated and maintained this plant for the past 10 years, and we had no hesitation in extending the agreement for a further five years. An uninterrupted reliable supply of electricity is essential to our production, and having our own power plant, built, operated and maintained by Wärtsilä, gives us this assurance,” said Lanre Opakunle, Strategic Sourcing Director, Power & Gas, Middle East & Africa, Holcim.

Wärtsilä has also supplied Lafarge Africa with another 100MW power plant located in Mfamosing.
