Q & A’s

Why is the Stegall to Scottsbluff 115,000 volt transmission line needed?

The Stegall to Scottsbluff transmission line project is being built to enhance transmission system reliability in the Nebraska Panhandle region and to meet the North American Electric Reliability Corporation’s Reliability Standards for the western Nebraska area. The project consists of building approximately 23 miles of new 115,000 volt transmission line from the existing Scottsbluff Substation to a new substation to be built approximately five miles south of Stegall near the existing Stegall Substation owned by Basin Electric Power Cooperative. The exact location of the new substation is yet to be determined.

Who determined the Stegall to Scottsbluff line was needed?  

NPPD is a member of the Southwest Power Pool (SPP), a regional transmission organization with members in nine states—Arkansas, Kansas, Louisiana, Mississippi, Missouri, Nebraska, New Mexico, Oklahoma and Texas. The SPP studies the needs of the entire transmission network within the SPP region. The SPP determined that the Stegall to Scottsbluff transmission line was needed to help ensure reliable electric service for the Nebraska Panhandle region.

Is the line route known?

The line route for the Stegall to Scottsbluff transmission line is not known at this time. The final route will be determined after a thorough siting study and a comprehensive public involvement process, including open houses, a public hearing, newsletters and more. NPPD’s goal is to minimize impact and find the most suitable route regarding items such as land use, public comment, environmental constraints, constructability, cost and electric system performance.

What is the cost of the project?

The total project cost estimate is $39 million. Of that amount, approximately $23 million is for transmission line work and the remaining money is budgeted for substation expenses.

When will line construction occur?

Transmission line construction for the Stegall to Scottsbluff line is expected to begin in 2016 and be completed by mid-2017.
