TransAlta Responding to Incident at its Cascade Hydro Power Facility in Banff Corridor

CALGARY, ALBERTA--(Marketwired - June 23, 2013) - Crews from TransAlta are working with teams from AltaLink and Fortis Alberta following an incident at TransAlta's Cascade hydro power facility in Banff National Park.

As a result of the incident, power has been cut to Banff and Lake Louise. An estimate of when power will be restored is not yet available, but repairs are expected to take a number of hours.

Hugo Shaw, Executive Vice-president of Operations at TransAlta says initial indications are that water that needed to be released from the Cascade facility backed up along the Trans-Canada highway adjacent to the facility and flowed over the highway, closing the highway between Banff and Canmore.

This water came into contact with a transformer at the facility, which failed. This is the source of the loud noise commented on by some observers. No injuries have been reported.

Shaw says the first step in the response is to get the water levels down in order to allow repair crews safe access the facility and restore power to the facility.

"We know that this incident is creating additional challenges during a very difficult time in the region, and we are doing everything we can to support the restoration of power to those affected, and to help get the highway re-opened."

Additional updates will be made available on TransAlta's website at and via the company's Twitter account ( and Facebook page (
