Western Alberta Transmission Line (WATL)

The Demand

In the last 20 years, Alberta has welcomed more than one million new residents and our demand for electricity has doubled, yet the backbone of the transmission system remains largely the same.

Challenges

To have electricity throughout the province at a flick of a switch, an efficient and reliable transmission grid is needed.

The Solution

The transmission system between Edmonton and Calgary is being reinforced to avoid reliability issues for consumers in southern and central Alberta, to improve the efficiency of the transmission system and to avoid system congestion to allow the competitive power generation market to work.

The Western Alberta Transmission Line project

  • is a 500 kV (500,000 volts) line.
  • will be built between the Genesee and Langdon areas.
  • will include a converter station at each end of the line that changes electricity from DC to Alternating Current (AC), so the DC line can connect with the rest of the province's AC system.

Construction Details

Depending on where you are in relation to the project, you may see or hear:

  • noise and construction crews
  • tree and vegetation clearing
  • transmission structure construction
  • wire stringing on the transmission structures
  • work at an existing substation
  • construction of a new substation

We expect construction will take about two years and the line will be in service in the spring of 2015. We will continue to communicate with landowners during the construction phase to provide the most up-to-date information.

Detailed Project Schedule
