Wärtsilä has secured a contract to provide flexible engine technology for an upcoming 217MW power plant in the US state of Nebraska.

The order was placed by Nebraska Public Power District (NPPD), a public corporation and political sub-division of the state.

The power plant, to be located near Hallam, will feature 12 Wärtsilä 50DF dual-fuel engines that primarily run on natural gas but can switch to diesel during natural gas supply interruptions such as extreme weather conditions.

Set for delivery in August 2027, the engines are a critical component of the plant, which is scheduled to begin commercial operations in 2028.

Wärtsilä's technology is designed to support the integration of renewable energy into the power system.

Wärtsilä Energy North America Engine Power Plants Energy Business director Jon Rodriguez said: “This project emphasises the importance of flexible engine power plant solutions in the energy system, providing reliable power supply and operations when needed.

“By meeting fuel resilient asset needs, and by enabling flexible generation, we are serving the local communities.”

Prior to this, the company secured a contract to supply engineering and equipment for a 217MW power plant in Liberty, Kentucky. Commissioned by the East Kentucky Power Cooperative, the facility will help bolster the grid's capacity to meet the increasing power requirement.

Last month, Wärtsilä was chosen to deliver a 204MW power plant solution for the Reko Diq copper-gold mining project in Pakistan. This plant, featuring 12 Wärtsilä 50 engines and auxiliaries, will ensure economical power supply for mining operations.
