An underground cable that affected the electrical distribution system is what caused Thursday’s power outage in Lyon County that affected 2,475 Dayton area customers, a NV Energy spokeswoman said.

“It was a bad underground cable which is what made it difficult to get to unlike an outage from a power line where it can be reached easily,” said Faye Andersen, spokeswoman for NV Energy.

Dayton area residents lost power at 5:37 p.m. with NV Energy able to make adjustments, by 7:30 p.m. reducing the number to 1,948 customers and by 9:30 p.m. 1,183 customers. By 10:30 p.m. 983 customers were without power and by 10:52 p.m. all power was restored, said Andersen.
