EPCOR plans to complete four projects within the Petrolia Substation throughout 2023 and 2024:
Disconnect Switch Replacement
Transformer Replacement
Current Transformer Replacement
Privacy Fence Replacement
Breaker Replacement
The February 2023 project notice update can be found here.
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 at the end of March 2023.
Transformer Replacement
EPCOR will be replacing a transformer within the Petrolia Substation that is nearing its end of life. This CVT transformer reduces high voltage so it can be used for metering electricity or operating protective measures within the substation. This replacement work will start in mid-March and take approximately two weeks to complete.
Current Transformer Replacement
EPCOR will be replacing a current transformer within the Petrolia Substation to increase the facility rating. Current transformers are used for metering electricity or operating protection measures within the substation. This replacement work will begin mid-June and is expected to complete early July 2023.
Privacy Fence Upgrade
EPCOR will be replacing the wooden privacy slats in the chain link fence around the substation. They will be replaced with plastic slats to ensure longevity. This work will start in early summer and is expected to take three weeks.
Breaker Replacement
The Breaker Replacement project has been delayed until Spring 2024. Additional information will be provided closer to the project start time.
