Burned insulators on a transformer at the Hays power plant led to a significant, but short-lived, outage late Saturday night in the Hays area.

Midwest Energy spokesman Mike Morley said the outage cut power to about 4,000 customers from approximately 11:10 p.m. Saturday to 12:20 a.m. Sunday as crews worked to back feed power from another source.

Midwest’s outage viewer showed power restored to all customers Sunday morning.
