The City of Trenton was without power for nearly an hour Thursday night. City Administrator Ron Urton says the power went out about 11:50 pm. City utility crews responded to the electric plant substation to get a large bird out of the NW Electric transformer. The bird had gotten into the system and caused a breaker to trip and knock out the power. Crew members checked for damage and reset the breaker. The city was without power for about 50 minutes.
