Muskrat Falls hydroelectricity flowing into Nova Scotia again

Deliveries of Muskrat Falls hydroelectricity to Nova Scotia areback on,ending a nearly month-long stoppage caused by a software problem in the transmission system in Newfoundland and Labrador.

The Labrador Island Link (LIL)went back into service on March 24 and electricity flow resumed that day.

"The full Nova Scotia Block of clean energy has been flowing and we have been receiving additional energy above what we're contracted to receive," saidNova Scotia Powerspokesperson Jacqueline Foster.

The 1,100-kilometre transmission system carries electricity from the big hydro dam in Labrador into Newfoundland. There it connects with Emera's transmission system and is sent across the Cabot Strait into Nova Scotia over the Maritime Link.

Late last month a fire sensor tripped on the Labrador Island Link.

The software did not respond correctly and the link was shut down while supplier GE Canada figured out what went wrong.

It was the latest in a series of software failures for LIL.

Muskrat Falls is supposed to supply about 10 per cent of Nova Scotia's electricity. Emera has contracted for 35 years of electricity from Muskrat Falls. It is an important part of meeting a provincial government commitment to have 80 per cent of electricity from renewable sources by the end of the decade.

Deliveries of the Nova Scotia Block only started to ramp up to full flows in recent months almost four years behind schedule.

Any shortfalls from this interruption will be made up later.
