The power plant is set to feature 12 Wärtsilä 50DF dual-fuel engines that primarily run on natural gas.
The power plant will be equipped with 12 Wärtsilä 50DF dual-fuel engines, primarily powered by natural gas but capable of switching to diesel during disruptions, such as extreme weather events. This flexibility ensures a stable energy supply under varying conditions. The engines are scheduled for delivery in August 2027, with the plant set to commence commercial operations in 2028.
The technology provided by Wärtsilä is designed to facilitate the integration of renewable energy sources into the regional power grid, supporting a more sustainable energy mix. Jon Rodriguez, director of Wärtsilä Energy North America’s Engine Power Plants Energy Business, stated: “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.”
This contract follows Wärtsilä’s recent projects to strengthen energy systems worldwide. In Liberty, Kentucky, the company secured a deal to supply engineering and equipment for a 217MW power plant commissioned by the East Kentucky Power Cooperative. That facility aims to enhance grid capacity to meet growing energy demands in the region.
Additionally, in July 2025, Wärtsilä was selected to deliver a 204MW power plant solution for the Reko Diq copper-gold mining project in Pakistan. That plant, equipped with 12 Wärtsilä 50 engines and supporting systems, is designed to provide a cost-effective and reliable power supply for mining operations.
The Nebraska project underscores Wärtsilä’s expertise in delivering adaptable and efficient energy solutions. By incorporating dual-fuel technology, the Hallam power plant will contribute to a reliable and resilient energy network, supporting both local communities and the broader adoption of renewable energy sources.
