Approximately 4,500 Homer Electric Association customers were without power for about 45 minutes, beginning at 8:05 a.m. Tuesday.
According to HEA spokesperson Joe Gallagher, the power failure was caused by a transmission problem at another utility within the power grid that services Southcentral Alaska.
"The reason was we had a transmission problem with Chugach Electric," Gallagher said. "The problem was with their line, but anyone on the grid is affected by it."
Gallagher said that as a result of the transmission loss, HEA automatically went into a load shed condition, causing power to be shut off to customers in much of North Kenai, Kenai and parts of Homer.
"It automatically required some reconfiguration of the grid," he said.
Gallagher noted the problem was quickly resolved, and the utility began restoring power to some homes within 20 minutes. By 8:45 a.m., HEA had restored power to all its customers, he said.
