Technology group Wärtsilä has signed a five-year long-term Operation & Maintenance (O&M) agreement with Lafarge Africa Plc, one of Nigeria’s leading building material producers. The agreement covers the 100 MW Lafarge Ewekoro power plant, which provides a dedicated supply of electricity to the company’s concrete and cement manufacturing processes. Signing of the O&M agreement took place in July 2021, and is an extension of a previous 10-year agreement.
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. Similarly, should the quality of the gas supply be disrupted, the Wärtsilä engines will continue to operate efficiently, delivering an assured and reliable power supply to the facility. Unlike gas turbine plants, the engines will also function efficiently with a low-pressure gas supply, thus providing a huge advantage given the region’s vulnerability to such interruptions.
The captive power plant provides the cement production facilities steady supply of electricity and an efficient use of available natural gas as primary fuel. By having Wärtsilä operate and maintain the power plant, the customer can focus on its core business to deliver construction materials to Nigeria.
“We have benefited significantly from the efficient way by which Wärtsilä has operated and maintained this plant for the past ten 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, Lafarge – a member of Holcim Group.
“Lafarge has been a customer with whom we have built a strong relationship over a number of years. Their readiness to renew this O&M agreement is a clear indication of satisfaction with our performance, and of how it supports the achievement of their business goals,” commented Marc Thiriet, Energy Business Director, Africa West, Wärtsilä Energy.
The scope of the agreement includes the operating crew, performance guarantees, plant availability, and spare parts. Wärtsilä has also supplied Lafarge with another 100 MW power plant located in Mfamosing, Nigeria. With a total of 200 MW of generating capacity to the same customer, Wärtsilä has established a high level of trust that validates the efficiency of the company’s flexible and reliable technology.
Since 2010, Wärtsilä has had a strong presence in Nigeria with a total installed capacity of 667 MW. The company locally employs approximately 90 people. In Africa, Wärtsilä has an installed footprint of more than 7000 MW.
