Update, 8:15 a.m.:
The Sand Lake substation was brought back online and power was restored after an outage of about an hour, Chugach Electric Association tweeted at about 7:50 a.m.
More than 6,000 Chugach Electric customers are without power fed by a substation at Sand Lake, the utility says.
“The high winds are likely to make this a busy day,” Chugach said in a Twitter post Tuesday morning.
