​In May 2022 EPCOR began equipment replacement work in the Petrolia Substation, the work within the substation will be ongoing through 2022 and 2023.​​

Project overview

​EPCOR currently has two electricity projects within our Petrolia substation: 

  • ​Disconnect Switch Replacement

  • Breaker Replacement

Disconnect Switch Replacement

Fifteen disconnect switches in the Petrolia substation have reached their end of life and need to be replaced. Disconnect switches are an important safety feature in a substation and are used to de-energize equipment in order to perform maintenance. This work began in May 2022 and is expected to be completed in March 2023.

Breaker Replacement

In Summer of 2023, EPCOR will be replacing six breakers within Petrolia substation. This work will take approximately six months to complete. Please see the project page on epcor.com/consultation for project updates.​
