We are building 3 230-kV transmission lines that will run between the new St. Vital, De Salaberry, Letellier, and La Verendrye stations. These lines will address growing electrical needs in south-central Manitoba, enable the Winnipeg network to withstand various severe outages, and promote reliability of our power system.

  • The first portion of transmission line runs from St. Vital Station south to De Salaberry East Station (V78G). Construction started in January 2020, was completed in December 2020 and is now in service.
  • The G79L transmission line continues south from De Salaberry East Station to Letellier Station. Construction started in September 2021, was completed in November 2022 and is now in service.
  • The Y36V transmission line starts at the St. Vital Station and runs to La Verendrye Station. Construction started in September 2022 and will be located on the Southern Loop.
    • The Sage Creek transmission corridor, part of the Y36V transmission line, was started in June 2020 and completed in October 2020. Areas disturbed by construction in the Sage Creek tall grass prairie were seeded in 2021 and rehabilitation was completed in summer 2022.
    • Tower construction and the stringing of lines from the St. Vital Station to La Verendrye Station transmission line started in October 2022. Implosion sleeves will be used along the right-of-way starting in June 2023 and continuing sporadically until construction is complete. Learn more about why we use implosion sleeves.

Public engagement

Feedback received through the public engagement processes helped inform route selection and environmental assessment. It was integral to ensure that we minimize effects on people and the environment.

Engagement goals for the St. Vital Transmission Complex were to:

  • share information as it became available;
  • obtain feedback for use in the assessment process;
  • gather and understand local interests;
  • integrate interests and concerns into the assessment process;
  • discuss potential mitigation measures.

Through a 2-round approach, we presented the project to local municipalities, First Nations, the Manitoba Metis Federation, parties, and local community members throughout 2013.

Round 2: preferred route (completed)

During the second round of engagement, we:

  • presented the preferred route and findings from Round 1;
  • discussed potential route adjustments;
  • discussed potential mitigation measures.

We undertook 4 open houses, an information session, various meetings and answered calls and emails. We thank all who participated and took the time to share their concerns and feedback with the project team.

Round 2 feedback helped us better understand the potential effects of the project and develop mitigation for concerns regarding the preferred route. The information gathered assisted in the finalization of the transmission line placement.

Round 1: alternative routes (completed)

During the first round of engagement:

  • introduced the project to the public and Indigenous communities;
  • produced feedback on alternative routes from the public and Indigenous communities;
  • identified interests, opportunities, and constraints;
  • gathered feedback that will feed into the environmental assessment.

During Round 1, we held 4 open houses, 3 stakeholder workshops, and answered calls and emails.

Environmental assessment

Environmental assessment

We have completed an environmental assessment for the St. Vital Transmission Complex and have submitted the report to Manitoba Environment, Climate and Parks (formerly Manitoba Conservation and Climate). This project is classified Class 2 development under The Environment Act (Manitoba).

The environmental assessment for the project included:

  • characterization of the environment;
  • identification of potential effects on people and the environment;
  • determination of mechanisms to avoid or reduce potential adverse effects while enhancing beneficial effects.

An Environment Act Licence was issued on January 30, 2017, by Manitoba Environment, Climate and Parks (formerly Manitoba Conservation and Climate).
