The first order comprises a 9-cylinder Wärtsilä 34DF dual-fuel engine generator set and is an extension to the existing generating capacity provided by a similar Wärtsilä engine generator set that has been successfully operating since 2017. The second order comprises a 12-cylinder Wärtsilä 34DF engine generator set and is intended to replace an existing inefficient mono-fuel generating asset in the plant with efficient dual-fuel generating capacity as part of Flour Mills Nigeria’s captive power plant modernisation plans. The Wärtsilä engine generator sets will be delivered during 2021 and are expected to become fully operational in early 2022.
The multi-fuel capability of the Wärtsilä engines, which can switch seamlessly from natural gas to liquid fuel mode while running at full load, facilitates continuous supply of electricity to critical loads in the event of uncertainties in the quality and quantity of the gas supply. In addition to maximising the availability and reliability, this inherent capability provides a valuable hedge against fuel price increases, and lends itself to accommodating future fuel infrastructure developments.
“It is always gratifying to receive repeat orders from a customer, not only because it signifies their satisfaction with our solution, but also because it cements the relationship between our companies. Operational flexibility and efficiency, which are features of the Wärtsilä engines, are becoming key issues in energy production, and are especially relevant for production facilities with a critical need for a reliable electricity supply,” commented Marc Thiriet, Energy Business Director, Africa West, Wärtsilä.
The Nigerian government’s 30-30-30 vision document for the power sector aims to achieve a capacity of 30,000 megawatts of electricity by the year 2030, with at least 30 percent being supplied from renewable energy sources. The selection of fast-starting and stopping Wärtsilä engines means that should the customer have access to solar or wind power in the future, these engine generator sets can provide smart back-up generation to balance the fluctuating supply from the renewables.
Wärtsilä has a leading position in supplying flexible power generation to West Africa with 4792 MW of capacity installed, of which 667 MW in Nigeria. Wärtsilä has operated in the country since 2010 and has about 90 employees locally.
