The St. Vital Transmission Complex includes construction of 3 230-kV transmission lines:

  • The transmission line (V78G) starts at St. Vital Station and runs south to De Salaberry East Station.
  • The line from De Salaberry East Station (G79L) will continue south to Letellier Station.
  • These 2 lines are required in south-central Manitoba to address load growth and voltage concerns.
  • Another line (Y36V) will start at St. Vital Station and run to La Verendrye Station. This new line will be located on a right-of-way known as the Southern Loop. The new line will:
    • enable the Winnipeg network to withstand various severe outages;
    • improve performance during normal operation;
    • promote reliability of the power system in southern Manitoba.

The St. Vital Transmission Complex received a Class 2 development Licence under The Environment Act (Manitoba) on January 30, 2017.

De Salaberry East Station to Letellier Station (G79L)

We started construction of the De Salaberry East Station to Letellier Station transmission line in September 2021. The transmission line starts at the De Salaberry East Station and runs south to the Letellier Station. Implosion sleeves will be used along the right-of-way and continuing sporadically until construction is complete. Implosion sleeves which make loud noises and flashes like a firework. Learn more about why we use implosion sleeves.

The construction progress map shows the transmission line, tower locations, and the status of construction by tower.

St. Vital Station to La Verendrye Station (Y36V)

We started construction of a new 230-kV transmission line south of Winnipeg in September 2022. The line starts at St. Vital Station (east of Winnipeg), runs along the Southern Loop right-of-way and ends at La Verendrye Station (southwest of Winnipeg).The section of the line from St. Vital Station to the floodway south of Sage Creek is already complete.

Areas in the Sage Creek tall grass prairie that were disturbed by construction were seeded in 2021. Rehabilitation in Sage Creek was completed in summer 2022.
