Unalaska's power is back on after two island-wide outages in the last two days.
The city's Department of Public Utilities has rerouted electricity around a damaged control switch at the powerhouse. That switch spurred the first, unscheduled outage Tuesday around 7 p.m.
"Everything tripped offline, meaning the generators and all the field breakers in the powerhouse opened up," said Utilities Director Dan Winters. "We found out one of our viper control switches was bad, and it blew a potential transformer."
