NPPD Storm Restoration coordinates crews, transmission line repairs, and substation work across Nebraska after severe storms, securing 345-kV and 115-kV lines, clearing Highway 81 hazards, and restoring power in Sutton, York, Hallam, McCool, and Geneva.

 

Breaking Down the Details

NPPD Storm Restoration fixes 345-kV and 115-kV lines, restores substations, and crews restore power in Nebraska.

  • 345-kV line damage between Hallam and McCool substations
  • About 100 structures on 345-kV corridor reported damaged
  • 35 structures damaged on McCool to Geneva 115-kV line

 

Crews from Nebraska Public Power District are assessing damage to four transmission lines that occurred recently during a storm and tornado outbreak that hit south central Nebraska.

 

NPPD also had one community it serves at retail lose power as a result of the storm and several NPPD wholesale customers were also impacted. NPPD is assessing damage in Sutton at the request of the city, and have sent crews to assist in restoring power to the community.

Preliminary reports indicate damage to the grid affecting approximately 100 structures on a 345-kV transmission line between a substation near Hallam and the McCool substation. Crews also secured the 345-kV line which was on the ground across Highway 81 and will continue to remove downed lines that are along other county roads.

Three 115-kV lines and structures damaged included a line from McCool to Geneva where approximately 35 structures were damaged, one structure damaged from Sutton to the Hastings Energy Center, and three structures from Davey to Wahoo. Also affected by these various lines being out were substations operated by South Central, Perennial, Seward County, and Norris Public Power Districts.

Additional outages to two other NPPD retail communities were also reported. One occurred in York where lightning reportedly struck an arrestor and locked out a transformer, affecting 1574 customers for approximately 39 minutes. Repairs were completed the following morning.
