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.

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 14 states in the central United States. SPP is a group of 84 members in Arkansas, Iowa, Kansas, Louisiana, Minnesota, Missouri, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas and Wyoming that serve more than 15 million customers. The SPP studies the needs of the entire transmission network within the SPP region. The SPP determined that the Stegall to Scottsbluff line was needed to help ensure reliable electric service for the Nebraska Panhandle region.

Is the line route known?

Yes, the final route was determined after a thorough siting study and a comprehensive public involvement process, including open houses, public hearings, newsletters and more. NPPD’s goal was 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 project began September 2016 and was completed by June 2017.
