Downtown Calgary to remain without power until Thursday

Power should be restored by Thursday​ to thousands of downtown Calgary businesses and residents left in the dark on the weekend by an underground electrical fire.

Mayor NaheedNenshi and officials from the utility held a press conference from the Calgary Emergency Management Agency headquarters Monday morning to give an update on the power outage that hit about 2,100 businesses and 5,000 residents Sunday. 

Power should be restored to the entire impacted section of the downtown by midday Thursday, said an Enmax official.

Transportation downtown should be almost back to normal for the Tuesday morning rush hour, said Nenshi. There will be some lane reductions.

He said 361 people showed up at Mewata Armoury's emergency information centre on Sunday, and about 270 people were helped with overnight accommodation.

"We hope that we have made things just a little bit easier for the people who were affected by the power outage," he said.

The damage from an underground fire in downtown Calgary on Saturday night was extensive, "completely destroying" the electrical infrastructure involved, the utility company Enmax said.

The city has been issuing updates on the situation on its Twitter feed @cityofcalgary.
