Unknown fault causes brief Juneau-wide power outage

Power was restored within half an hour

An unknown fault in a transmission line caused a brief power outage across Juneau Sunday night.

“We don’t know the cause of the outage yet,” said Alaska Electric Light and Power vice president of consumer affairs Debbie Driscoll in a phone interview. “We had a fault on our transmission line one.”

The fault occurred at 10:56 p.m. Sunday evening. The last customer had power restored within half an hour, Driscoll said.

“The system worked as it is intended to,” Driscoll said.”The tripping open of the line is a protective mechanism.”

The company shed most of the load as they worked to bring a backup transmission line up, cutting power to most of Juneau, except for locations such as Bartlett Regional Hospital. AEL&P will now work to isolate the fault in the first line, Driscoll said, a process that could take some time.

In the past, reasons for an outage range from landslides to animals, Driscoll said.

“Some of that line is not visible from the road,” Driscoll said. “It requires the crew to go up and patrol the line.”

The redundancy is built in for just such an occasion, Driscoll said.

As power was restored, areas were brought up one by one through substations. Operations will continue as usual on the number two line while AEL&P personnel works to correct the issue, Driscoll said.

To capture the unexpected action- the unrepeatable moment- it should be instinctive.  In order to build the story you have to shoot the adjective.  In this photo the bald eagle had waited patiently for the right moment to pounce on an unsuspecting vole… the unexpected.  The best way to accomplish this is to master the art of the most difficult subject to photograph– birds in flight.  In order to do this you must learn your gear; it must become part of your muscle memory so you can concentrate on the story you are witnessing.
