Sunday night's storms will be costly for the Nebraska Public Power District. The state's largest utility reports damage to four major transmission lines. About 100 poles were damaged on a large 345 kilovolt line running from Hallam to McCool Junction. At one point in the storm, that line fell to the ground across U-S Highway 81. Another 100 kilovolt line, from McCool Junction to Geneva suffered damage to 35 poles. One NPPD Line was damaged near Sutton, and another from Davey to Wahoo will need repairs also. Numerous outages were reported from lightning strikes at sub-stations. One of the biggest left about 1,000 customers in the dark in Milford last night.
