Canada is home to some of the largest hydro power facilities in the world: the 5429MW Churchill Falls underground power plant in Labrador, the 5328MW Robert-Bourassa Complex near James Bay, Québec and the 214m-high Daniel-Johnson arch-and-buttress dam on the Manicouagan river in Québec, to name just a few.
There are 475 hydro power plants in Canada, of which 233 have a generating capacity of more than 10MW and represent 99% of total hydropower capacity.
Canada generates about 353TWh/year of hydro power, which is close to 60% of its total electricity production. [With an installed capacity of 69,205MW (2002), Canada is the world’s biggest producer of hydro power. Leading the US, Brazil, China and Russia, Canada’s output is nearly 13% of the global output].
In addition to existing facilities, Canada has many opportunities for new hydro project development. Approximately 118,000MW of hydro power, twice the amount that is currently in operation, could technically be developed. The three territories and all the provinces, except Prince Edward Island, hold some remaining potential. The provinces of Québec, Manitoba, British Columbia, and Newfoundland and Labrador in particular hold significant potential for development.
Several recent agreements signed with aboriginal communities will increase cooperation and partnership for the development of new hydro projects. In the Province of Québec, an agreement was signed in 2004 between the Cree Nation and Hydro-Québec, whereby the utility agreed to facilitate the participation of the James Bay Crees in hydroelectric development through partnership, employment and contracts. In Manitoba, the Nisichawayasihk Cree Nation will be an equity partner with Manitoba Hydro in the development and operation of the planned Wuskwatim generating station on the Burntwood river. The low head design of Wuskwatim will produce 200MW, while flooding only 0.5km of land. The planned project start date is January 2005.
Across Canada, several other new projects are being planned, such as the Waneta hydroelectric expansion project (435MW) in British Columbia; the Eastmain 1A (5.6TWh), La Romaine (1500MW), Chute-Allard and Rapides-des-Coeurs (138MW) in Quebec, and Gull Island in Labrador.
Under construction in Québec are the Eastmain (480MW), Péribonka (385MW), Toulnustouc (526MW), Grand-Mère (220MW), and Mercier (50.5MW) projects.
Moreover, Québec has four refurbishment projects in the works: Outardes-4 (56MW), Outardes-3 (254MW), La Tuque (51MW) and Bersimis-1. In British Columbia, the Brilliant Expansion project, scheduled for completion in 2006, will generate up to 120MW.
The Niagara tunnel is an important refurbishment project underway in Ontario. It will add a third water intake tunnel to supply existing generating stations, which will produce an additional 1.6TWh per year when the project is completed in 2009. In Manitoba, the Kelsey project consists of refurbishing all seven units with a projected increase of 11MW per unit, representing an overall 30% increase in output. The work should be completed by 2015.
Typically, large projects can take between 8-12 years to complete, including regulatory review, consultations, planning, construction and commissioning. The lengthy regulatory process that hydro power projects must undergo includes comprehensive environmental assessment and public consultations; this process significantly slows down the development of new hydro projects. Notwithstanding these delays, the development of new hydro power capacity has become a matter of urgency. Over the next two decades, the demand for electricity will increase on average by 1.3% per year; the question is how to meet Canada’s electricity needs without compromising the environment. Growing concerns about greenhouse gas emissions, together with increasing recognition of hydro power as a clean and low-emitting source of electricity, put further hydro development in a good light.
Age structure in the industry
Total labor force of Canada was 17.37 million (2004), which is distributed within these major occupations: agriculture 3%, manufacturing 15%, construction 5%, services 74%, other 3% (2000) (CIA Facts). Due to lack of information regarding the age structure of people working in hydropower industry, a more broad perceptive has been used for research. It uses the term put forward by International Labour Organization (ILO) commonly know as economically active population i.e. The economically active population comprises all persons of either sex who furnish the supply of labour for the production of economic goods and services as defined by the United Nations systems of national accounts and balances during a specified time-reference period (ILO).
• The University of British Columbia’s civil engineering department has a hydrotechnical engineering programme, which is targeted towards students who want to specialise in subjects such as hydrology, hydraulics, environmental fluid mechanics, or coastal engineering. Alternatively, students may choose a broad programme such as water resources management, which would include elements of hydrology, hydraulics, systems engineering and pollution control engineering.
