​March 2021 update

The transformer replacement was completed in October 2020. In spring 2021, a transformer oil containment enclosure will be installed, in which this project will be completed.

Project overview

One of the transformers at our Namao Substation is nearing the end of its useful life and requires replacement so we can continue to deliver reliable electricity to Edmontonians in this area.

The project will entail:

  • Replacing one transformer that is nearing the end of its useful life with a similar-capacity unit
  • Removing two external voltage regulators; one that is currently in-service and one that was previously decommissioned. The function of the in-service regulator will be included in the new transformer.
  • Installing a transformer oil containment enclosure

The Namao Substation is located at 97 Street and 127 Avenue in the Lauderdale neighbourhood.
