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

Calgary, Alberta (June 22, 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.”

EX-99.2

Power Restored to Banff and Lake Louise Following Completion of Repair Work at TransAlta’s Cascade Hydro Power Facility in Banff Corridor

Calgary, Alberta (June 23, 2013) – Following overnight repairs to a damaged transformer at TransAlta’s Cascade hydro power facility in Banff National Park, power to the towns of Banff and Lake Louise was restored at 2:45 a.m. this morning.

On June 22, 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 also came into contact with a transformer at the facility, which failed, creating a loud noise heard by some in the area. The transformer failure cut power from the facility to Banff and Lake Louise. At no time was the integrity of the Cascade facility affected.

Initial response efforts focused on reducing the levels of the backed up water around the transformer, in order to allow safe access for workers to begin repairs.

Hugo Shaw, Executive Vice-president of Operations at TransAlta says “we were able to complete the repairs safely due to the hard work and diligence of the TransAlta operating team, CP Rail, Fortis and Altalink.”
