​March 2021 Update

One transformer replacement was completed in October 2020. The other transformer is scheduled to be replaced by the end of December 2021.

Project overview

Two of the transformers at the Strathcona Substation are nearing the end of useful life and requires replacement so we can continue to deliver reliable electricity to Edmontonians in this area.

If the project is approved, we'll:

  • Replace two transformers that are nearing the end of their useful lives with similar-capacity units
  • Remove 11 external voltage regulators from service, as their function is now included in the new transformers

​Transformer #2

  • April 2021: We'll begin replacing this transformer and expect that it will take about three months to complete
  • December 2021: Once the new transformer is in service, we'll remove 5 external voltage regulators from service. The entire project should be completed by the end of December 2021.

Please note: These timelines are estimates and may change based on weather, procurement of materials, and construction conditions.
