A major test of the troubled transmission line from Labrador to the Avalon Peninsula scheduled for Thursday knocked out power to thousands of customers shortly after 10 a.m.
Efforts to commission the high-voltage power line from Muskrat Falls to Newfoundland's Avalon Peninsula have again run into problems, but this time the bug-prone computer software does not appear to be the primary reason.
Long delays in perfecting a computer software needed to safely transmit Muskrat Falls electricity to Newfoundland are largely responsible for a $256-million increase in project costs, N.L. Hydro officials said Friday.
An independent assessment of the power generating station at Holyrood reveals that the aging oil-fired plant can operate until at least 2030 as a backup to Muskrat Falls, but it won't be cheap.
