OPPD Enters Partnership With Kiewit to Add Natural Gas Generation, Upgrade Turbines

The Omaha Public Power District has entered a partnership with Kiewit Corporation, an Omaha-based construction and engineering firm, to add new natural gas generation and upgrade two existing natural gas turbines. 

The agreement announced last Tuesday paves the way for three new natural gas units at OPPD’s Cass County Station and one additional unit at Turtle Creek Station in Sarpy County. Each unit can generate up to 225 megawatts (MW) of electricity and start up quickly to help respond to grid and load demand as needed. These projects were originally announced in February 2024.  

Kiewit’s power division will also help OPPD convert two natural gas units at Cass County Station to dual fuel generators, allowing them to run on either natural gas or fuel oil as a backup. Being able to use multiple fuels gives OPPD more flexibility with its operations. 

Combined, the new generation turbines at Turtle Creek and Cass County Stations will have the ability to generate around 900 MW once all work is complete.

Under the agreement with OPPD, Kiewit will design everything necessary to set up and operate the turbines efficiently, procure many of the materials for the project and handle construction work, which is expected to start in spring 2025 at Cass County Station and shortly thereafter at Turtle Creek Station.
