Newfoundland and Labrador Hydro's largest hydroelectric generating station on the Island Interconnected system is located at Bay d'Espoir. The Bay d'Espoir Hydroelectric Generating Station consists of seven generating units producing a total capacity of 604 MW which is approximately 39 percent of the Island Interconnected System's installed capacity. Units 1 through 4 went online between 1967 and 1968, with each unit having a rated capacity of 75 MW.
During the summer of 2010, generating unit 2 underwent a major refurbishment, including a stator rewind, rotor pole re-insulation and protection upgrade. This project was the first stator rewind on a unit of this size in Newfoundland and Labrador Hydro's history, and marks the beginning of the replacement of many of Hydro's major assets that were put in place during the late 1960s.
