Q & A’s

Why is the Hoskins-Neligh transmission line needed?

The Hoskins-Neligh transmission line will help improve electric reliability in north central Nebraska. The hot, dry summer of 2012 led to much higher than anticipated electrical loads for NPPD, particularly irrigation load. Between June 27 and August 14, 2012, NPPD surpassed its previous record energy loads 30 times. NPPD and other area electric utilities asked customers to reduce their energy usage to avoid outages. The Hoskins-Neligh line is one of several ways NPPD is addressing the energy demands in this area. NPPD is also enhancing its existing system and those improvements will be complete by the summer of 2013.

Who determined the Hoskins-Neligh line was needed?  

NPPD is a member of the Southwest Power Pool (SPP), a regional transmission organization. The SPP conducted a three-year study, also known as the Integrated Transmission Plan, to assess the needs of the entire transmission network within the SPP region over the next 10 years. The study identified the need for two, 345-kilovolt transmission lines in Nebraska, with one segment to run from NPPD’s Hoskins substation located southwest of Hoskins to a new substation in the Neligh area. The location for the Neligh substation has not been determined. The other line segment will run from NPPD’s Gerald Gentleman Station near Sutherland to a new substation to be sited adjacent to NPPD’s existing substation east of Thedford. The new line will then proceed east and connect to a second substation to be sited in the Holt/Antelope/Wheeler County area.

What are the benefits of this transmission line?

The Hoskins-Neligh 345-kilovolt transmission line will enhance reliability of the transmission system, provide a high capacity line to north central Nebraska, reduce existing system congestion to allow for better utilization of NPPD’s diverse generating resources, and provide for further wind-powered generation projects in the state.

Is the line route known?

The line route for the Hoskins-Neligh transmission line was finalized and announced on October 2, 2013. 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 in terms of land use, public comment, environmental constraints, constructability, cost and electric system performance.

What is the cost of these lines?

The current cost estimate is approximately $77.7 million.

When will line construction occur?

Transmission line construction for the Hoskins-Neligh line is expected to begin in the spring of 2015 with an in-service date of mid-2016.
