GIS data – project infrastructure for download

This zip file contains spatial files in ESRI Shapefile format of the project infrastructure. They are viewable using geographic information system software. We recommend extracting the files to your computer, rather than opening them online. The .kml file will allow you to view the route(s) with software such as Google Earth®.

Do not download these files if they are beyond your computer’s or internet connection’s ability as they can cause your computer to temporarily stop working (require a restart).

Round 2

Round 1

Environmental assessment

We have completed an environmental assessment for the St. Vital Transmission Complex and have submitted the report to Manitoba Sustainable Development. 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 Sustainable Development.

Route selection

To assist us in determining a preferred route, we used a process based on EPRI-GTC Overhead Electric Transmission Line Siting Methodology.

This process:

  • Incorporates feedback on routing criteria from internal and external parties from engineering, natural, and socio-economic perspectives.
  • Considers these perspectives and narrows a corridor for routing a transmission line.
    • Develops alternative routes within this corridor that are presented for feedback through our public and Indigenous engagement processes. Input received through public and Indigenous engagement helps assist in determining a preferred route that minimizes impact on people and the environment.
