The Crown corporation that generates most of the electricity in Newfoundland and Labrador says one of the four turbines at the Muskrat Falls hydroelectric dam will likely be taken apart and repaired because of vibrations first detected in 2021.
Jennifer Williams, CEO of Newfoundland and Labrador Hydro, said Wednesday the work needed on Unit 2 won’t affect the utility’s supply of electricity to customers inside or outside the province. As well, Williams said the material costs will be covered by insurance.
