A new substation and transmission lines have been approved for Edmonton, which will expand the growing city’s electricity system and capacity.
The multi-year project – at an approved cost of $398 million – is being described as one the largest power grid upgrades in Edmonton’s history, according to EPCOR.
Construction on a new high-capacity substation in northeast Edmonton – on empty land near Fort Road and Yellowhead Highway – is scheduled to begin this summer and end in 2029.
The project includes five kilometres of new underground high-voltage transmission lines and four km of 72-kV connection lines around the existing Namao Substation.
EPCOR says the existing transmission system in the city’s northeast is approaching its capacity limits.
“This project reinforces, modernizes and adds capacity to Edmonton’s electricity system to make it more resilient in the face of growing demand and hotter summer weather,” said Kirstine Hull, EPCOR’s executive vice-president of electricity services.
The cost of the project will be applied to monthly electricity bills, which are expected to increase by $0.25 at the project’s peak.
“Costs begin appearing as project components are completed and decline over the infrastructure’s estimated 40-year life,” EPCOR says.
The Alberta Utilities Commission (AUC) approved EPCOR’s City of Edmonton Transmission Reinforcement (CETR) project following an independent review.
