News Releases : OPPD awards EPC contract for Power with Purpose project

Omaha Public Power District announced today that it’s made a key selection for its Power with Purpose (PwP) project. PwP will add 400 to 600 megawatts (MW) of utility-scale solar and 600 MW of natural gas to OPPD’s generation portfolio.

The utility awarded an engineer, procure, and construct (EPC) contract to Zachry Group The company will be responsible for the design and construction of both of OPPD’s new natural gas generation facilities -- Standing Bear Lake Station, a 150 MW facility in Douglas County, and Turtle Creek Station, a 450 MW facility in Sarpy County – as well as their associated substations. Both of these plants are peaking stations, which means they will only run as needed, per market conditions (estimated at less than 15% of the time).

The solar and gas generation capacity PwP will build supports reliability and resiliency of the system as our communities grow, while significantly positioning OPPD on a path to meet its net zero carbon goal in 2050.

Preliminary grading at both natural gas generation sites related to PwP has begun, and major construction is scheduled to start in the first quarter of 2022.

In July, OPPD announced two other contracts related to PwP. The utility selected Siemens Energy to provide two SGT6-5000F combustion turbines to power the 450 MW Turtle Creek Station, a simple-cycle turbine facility. This facility will be in commercial operation by late summer of 2023.

OPPD also selected nine Wärtsilä 18V50DF reciprocating internal combustion engines to power the 150 MW Standing Bear Lake Station. Standing Bear Lake Station will be in commercial operation by late spring of 2023.
