Red Deer Area Transmission Development

Project overview

Red Deer and the surrounding areas have grown significantly in recent years and the demand for electricity has increased. Transmission system reinforcements are required to make sure homes, farms and businesses continue to have a reliable supply of electricity for years to come.

Stage 1 of the development was completed in late 2013. On July 29, 2014, AltaLink received approval from the Alberta Utilities Commission (AUC) to construct componants that fall under stages 2 and 3 of the development.

Currently we are preparing for construction activities in the Ponoka, Didsbury, Sylvan Lake and Red Deer areas. Construction in the Innisfail area is scheduled to begin in the summer or fall of 2015. Construction on all project components is expected to be complete by the summer or fall of 2016.

Project updates

Read AltaLink's letter to the editor of the Red Deer Advocate - printed on Friday, October 10, 2014

There has been some misinformation in the public recently about AltaLink's Red Deer Area Transmission Development. On October 7, 2014 AltaLink submitted a letter to the editor in order to clarify details about the project and AltaLink's processes, especially with respect to the portion of the project that goes through the Pines neighbourhood in the City of Red Deer.

New transmission line east of Lacombe (423L) 
As part of Stage 3 of the development, AltaLink is also proposing to build a new transmission line, called 423L, east of Lacombe. AltaLink included this component in the original application that was filed with the AUC but we are continuing to look at our options for the proposed new transmission line. As a result, the AUC has postponed its consideration of the 423L component. AltaLink is continuing to communicate with stakeholders near the proposed 423L transmission line as the project progresses and we submitted a revised application to the AUC for the 423L project on October 6, 2014.

Project details

The proposed Red Deer Area Transmission Development is divided into five stages.

  • Stage 1substation upgrades: upgrading six substations
  • Stage 2transmission line rebuilds: rebuilding nearly 75 kilometres of existing transmission lines in the Red Deer and Sylvan Lake areas
  • Stage 3new substations and transmission lines: building new substations near Ponoka, Innisfail and Didsbury and building approximately 50 kilometres of new transmission lines near the substations and east of Lacombe
  • Stage 4removing existing transmission lines: removing approximately 75 kilometres of transmission line from Wetaskiwin to Lacombe and approximately 25 kilometres of transmission line from Red Deer to Innisfail
  • Stage 5 - 166L transmission line rebuild: rebuilding approximately 15 kilometres of existing transmission line and upgrading an existing substation near Didsbury
