[quote:Anonymous Coward 24742414:MV8yMDA0OTMyXzMzNjg1ODk2X0E1RERGNTkw] Power Outage in USA on Monday, 01 October, 2012 at 04:29 (04:29 AM) UTC. Description Power has been restored to about 17,000 Xcel Energy customers who were affected Sunday evening by an outage in the Greeley area. Xcel Energy spokeswoman Michelle Aguayo said at least 16,900 customers in Greeley, Garden City, Evans, LaSalle and surrounding areas were affected. She said the outage originated at a Greeley substation at 6:18 p.m. The outage lasted a little more than two hours. As of Sunday night, Aguayo said crews were still trying to determine the cause of the outage, but it did not appear to be weather-related. Xcel Energy’s outage hotline was inundated with calls. Aguayo said the company encourages customers to call and leave messages. Paul Sadd, a mechanic at North Colorado Medical Center, said the hospital was running on emergency power during the outage. He said several people were stuck in elevators, but workers were able to get them out safely. Aguayo said Xcel works closely with large customers like hospitals and law enforcement agencies to ensure that they have back-up power resources. http://hisz.rsoe.hu/alertmap/site/?pageid=event_desc&edis_id=PW-20121001-36719-USA [/quote]
