All Customers Back in Service; Outage Caused by Major Failure on Xcel System

This message was updated at 9:50 p.m.

United Power was affected by a major outage on Xcel Energy's system. They lost a substation that subsequently caused United Power's system to protect itself by interrupting power to the affected substation. Information about the problems that Xcel experienced can be found here. The United Power substation that was affected, Silver Saddle, is located just south and east of Henderson. There were also a few isolated transformers that were damaged by the power surge that started Xcel Energy's problems this evening.

We initially had to inspect the substation to assure that there was no damage, and then began the process of repowering the system. The outage began at approximately 6:30 pm and all customers were back on by 9:07 p.m. While outages are inconvenient, the electrical system contains a number of elements that help to protect the infrastructure of our electric grid. The equipment that tripped off did so to protect the system – including the homes and businesses we serve.

Thanks for everyone's patience, and thanks to those of you that took the time to report your outage via our automated system.
