From the ground up; Nova Scotia Power successfully builds new transmission towers and powerlines across Strait of Canso

AULDS COVE, NS – Tom Flewwelling gazes skyward at one of six new transmission towers situated across the Strait of Canso gracefully draped with high voltage powerlines, with a contented smile on his face.

“It’s a bit surreal to see every component of this project now in place and working as it should – it’s been on my mind every day for the past eighteen months, so I’m really happy that we’re up and running,” said Flewwelling, Senior Project Engineer with Nova Scotia Power.

The company built six new transmission towers and installed six high voltage powerlines alongside an existing transmission corridor to enable clean hydroelectricity from Newfoundland and Labrador via the Maritime Link to reach customers across the province, and provide an important backup connection between the Mainland and Cape Breton in the event of an outage.

As Flewwelling can attest, constructing some of Canada’s tallest transmission towers is no small feat, particularly when the towers and lines are being installed over active road and waterways.

“The tower construction was likely the most impressive sight from a bystander point of view – they are the tallest towers in Atlantic Canada and it took a careful combination of personnel, cranes and helicopters to get the job done,” he said. “Installing the powerlines was an entirely different piece of work that required a series of scheduled road and marine interruptions, and coordination by team members separated by various distances to successfully mount and secure these heavy wires. Every aspect of the plan was scrutinized from a safety standpoint and repeatedly tested before execution - I’m very proud of the team for safely completing this challenging work.”

In total, the project represents a $20 million investment in service reliability for the Strait Area and a commitment to cleaner electricity in Nova Scotia for years to come. In 2017, 29 per cent of electricity came from renewable energy sources, and the company is on track to achieve 40 per cent in 2020.
