Quick Facts

  • BC Hydro has reported Thursday's storm was the most devastating windstorm in 20 years.
  • Staff believe the issue occurred when the generator failed or restarted and sent a bump of ‘bad power’ through the plant’s control system. This caused a control device to fail. Operators diagnosed the problem with the assistance of Nanaimo Forest Products and Associated Engineering staff, and were able to swap a spare device in its place.
  • At 4:00 a.m. on December 21, 2018, generators in the City of Nanaimo's water treatment plant suffered a breakdown. Plant operators were able to restore generator power however, a number of critical faults within the plant have been interrupting production.
