About 12,000 Homer Electric Association customers between Sterling and Homer experienced a power outage Friday, with some residents going without power for nearly 45 minutes.
The outage was due to a problem at the Bradley Hydroelectric Plant, a plant near Homer owned by the state of Alaska and operated by HEA.
“One of the units at the hydroelectric plant tripped off line and as a result of that, because it’s a large power supplier, there was a large voltage drop in the system,” said Joe Gallagher, HEA’s spokesperson.
The plant tripped offline, he said, because a large tree near Indian fell on the main transmission line between Anchorage and the Kenai Peninsula. The impact jolted the system all the way to the plant.
“When that happens, we have what’s called load shed, an automatic shutdown of a number of circuits in order to deal with the loss of the voltage,” he said. “It did what it was supposed to do.”
The load shed occurred at 11:39 a.m.. HEA workers had power restored at 12:22 p.m.
