Rolling blackouts and power outages throughout Canada's Newfoundland and Labrador province in January have prompted the Board of Commissioners of Public Utilities (PUB) to launch a probe into Nalcor Energy and its management of power generation and transmission infrastructure.

PUB's announcement of the investigation comes after a number of public complaints claimed that utility corporations Nalcor and Newfoundland and Labrador Hydro had focused all their development efforts on the approximately $7.8-billion Muskrat Falls hydropower project, now under construction, while neglecting crucial, existing infrastructure.
