Muskrat Falls’ power to Nova Scotia stopped indefinitely

Nova Scotia

Key takeaways: 

  • Software failure strikes problem-plague Labrador Island Link transmission system.
  • Labrador’s Muskrat Falls hydro dam has suffered numerous uncertainties and is billions over funding. 

Electricity supply to Nova Scotia stopped: 

Deliveries of Muskrat Falls hydroelectricity to Nova Scotia have ceased, and it is not clear when they will restart.

The latest software letdown in the Labrador Island Link transmission system results.

The 1,100-kilometre Labrador Island Link has electricity from the giant hydro dam in Labrador to Newfoundland. It links with Emera’s transmission system and is sent across the Cabot Strait into Nova Scotia through the Maritime Link.

But supplies of the so-called Nova Scotia Block stopped after a fire sensor strumbled one of the lines in February.

The software did not react correctly, and once again, supplier GE Canada is digging for the reason of a fault with the Labrador connection, which has suffered repeated setbacks.

Newfoundland Labrador Hydro told local regulators the link will “remain offline while these incidents are probed.”

A long record of issues

“It is affecting,” said consumer advocate Bill Mahody, representing Nova Scotia Power’s 400,000 residential clients in rate hearings.

“There’s a rather long history here of this portion of the project-inducing issues. But they’re the kinds of issues that Nova Scotia Power Maritime Link has represented to the [Nova Scotia Utility and Review Board] were on their way to being fixed.”

Ratepayers have been paying the Emera aid Nova Scotia Power Maritime Link for the Maritime Link since 2018 and just lately begun collecting total amounts of the Nova Scotia Block — supplying nearly 10 percent of the region’s electricity.

Full delivery came as the Nova Scotia Utility and Review Board considered Emera’s application to retrieve $1.7 billion from Nova Scotia Power clients over the following 35 years.
