The challenge
As Nebraska’s energy mix evolves—with electricity generation historically reliant on coal and supported by a strong and growing wind portfolio—Lincoln Energy System (LES) required a solution that could respond quickly to fluctuations in demand, complement intermittent renewable generation, maintain high reliability and operational efficiency, and support long-term planning for a resilient grid. With increasing demand and a diversifying generation portfolio, fast-start, high-cycling capability became essential to help stabilize the grid and reduce the risk of supply shortages.
The solution
The LM6000VELOX aeroderivative gas turbine provides full power in under 10 minutes, delivering the operational flexibility required to respond to peak demand and changing grid conditions. Its high cyclic life enables frequent starts and stops without compromising performance—an important feature when integrating renewable energy sources.
With more than 40 million operating hours and over 1,300 units shipped worldwide, LM6000 gas turbines have accumulated more operating experience than any other aeroderivative turbine greater than 40 MW. The platform offers greater than 99% start and operational reliability and over 98% availability.
By deploying two LM6000VELOX units, LES is not only expanding plant capacity but also strengthening grid reliability and supporting its long-term generation strategy—ensuring the additional 100 MW of flexible capacity aligns with the region’s growing residential and commercial development needs.
