Côte St-Catherine

Business Segment:
Hydroelectric

Location:
At the Côte Ste-Catherine lock of the Lachine section of the St. Lawrence Seaway, Québec

Installed Capacity:
11,120 kilowatts

The Côte Ste-Catherine Facility is located at the Côte Ste-Catherine lock of the Lachine section of the St. Lawrence Seaway. The bypass canal upon which the facility is located was constructed as part of the St. Lawrence Seaway in 1958. The facility has a total installed capacity of 11,120 kilowatts and was constructed in three separate phases, each phase having a total installed capacity of 2,120 kilowatts, 4,500 kilowatts and 4,500 kilowatts, respectively, and each phase was commissioned in 1989, 1993 and 1996, respectively. Due to the year round, high volume water flows of the St. Lawrence River, the Manager expects there to be sufficient water to operate the Côte Ste-Catherine Facility at full capacity throughout the year. The Côte Ste-Catherine Facility uses approximately 2% of the river flow at any given time.

The term of the power purchase agreements for each of the Côte Ste-Catherine — Phase I facility is 20 years from the commercial start-up date and 25 years for Phase II & Phase III facility. The power purchase agreements expire in 2009, 2018 and 2021, respectively. The agreements may be renewed at the option of the producer for a period not exceeding the original term upon terms imposed by Hydro-Québec
