Non-hydro renewable sources currently contribute 5. Wind has become the predominant non-hydro renewable source surpassing biomass e. An emerging source, solar provides a still small but rapidly increasing amount of electricity.
Larger image. The bar chart displays electricity generation in Canada from to , in terawatt hours TWh. The bars of different heights indicate that generation was TWh in and increased to TWh in , and then increased again to TWh in Historically, provincial governments tended to ensure that enough electricity generation capacity was developed within their boundaries to meet provincial needs.
As a result, a limited amount of electricity is traded between neighbouring provinces and with the United States. Still, a certain amount of trading takes place as it provides opportunities for sellers to increase revenues by selling electricity that might otherwise go to waste and opportunities for buyers to ensure adequate supplies in periods of high demand or during outages at generating plants.
Some trading reflects seasonal circumstances in that electricity demand peaks during the winter in Canada and peaks during the summer in the United States. As well, hydroelectric utilities with water reservoirs may boost production during daily peak demand periods in order to export electricity at advantageous prices, and then reduce production while refilling the reservoirs during off-peak periods while importing electricity at lower prices.

In recent years, Canada has been a net exporter of electricity to the United States. In , export sales to the United States amounted to The bar chart displays exports and imports of electricity in Canada from to , in tetrawatt hours GWh. The blue bars of different heights indicate that exports were about Another set of red bars that represents electricity imports indicates an overall decreasing trend from Electricity prices differ across Canada due to a number of factors; the most significant of them are the market structure and the type of available generation.
Alberta has a deregulated electricity market where prices are market-based. Ontario has partially restructured its electricity market.
In other provinces and territories, electricity prices are set by electricity regulators. The type of available generation is reflected in the cost of generating electricity, which is the important element of electricity pricing. It varies by province or territory depending on the sources used to produce electricity. Hydroelectric stations currently provide some of the lowest-cost electricity in Canada. However, as the most economical projects were developed first, new hydroelectric projects may have higher production costs.
Hydroelectric and nuclear power plants are fairly capital intensive, which means that a major portion of the generation costs pertains to the cost of building the production infrastructure. Operating and fuel costs are relatively low compared to other electricity sources. In the case of natural gas and petroleum-based generation, the cost of fuel accounts for a large portion of total generation costs.
Because of this, the cost of generating electricity from these fuels fluctuates with changes in the prices of these fuels. Coal-fired power plants fit in the middle of this spectrum, with mid-range capital costs and mid-range fuel and operating costs. Other important elements of the pricing of electricity, in addition to the market structure and the cost of generation, are the costs of its transmission and local distribution.
These costs vary across Canada, depending on factors such as geography and population density.

Canadian consumers benefit from some of the lowest electricity prices in North America. In , average prices for residential customers, in cents per kilowatt-hour, were 8. Because of the technical limitations on storing electricity, electric utilities and governments work to ensure that enough electricity is available to meet demand at any given time and to avoid power outages. Several actions are also taken to ensure the reliability of the electricity grid.
Having a generating capacity in excess of the expected peak demand is one way to ensure reliability.
This allows electric utilities to still meet demand when some generation capacity may be offline because of routine maintenance or unexpected shutdowns. Utilities may also secure access to additional supplies by trading electricity with neighbouring utilities, including those in the United States. Adequate transmission is also vital to ensure reliability. Transmission allows for moving electricity from areas with excess electricity to areas where electricity is needed. Electricity can be transmitted both within the area of distribution of a given utility and between utilities.
Several other actions are taken to ensure reliability, including the careful management of the electricity grid in real time and the adoption of standards and operation procedures. Electricity demand in Canada is expected to grow at an annual rate of 1 per cent between and Most of the growth in energy demand would come from the industrial sector, where overall energy demand is expected to grow at a rate of 0.
In order to meet increasing demand, Canadian producers will increase their generation capacity.

The sources of future supply increments will depend on the policy and business decisions made by provincial governments and power producers, respectively. Hydroelectricity generation is expected to continue to dominate the electricity supply mix but its share will decrease from 55 to 51 per cent in In total generation, the share of wind power is projected to increase from over 7 per cent of total electricity generation in to close to 11 per cent by , while the share of biomass, solar and geothermal will account for about 5 per cent by , so that over the forecast period, the share of renewable sources in total generation is expected to be about 67 per cent.
Natural gas-based generation is set to increase with its share in total generation increasing from 15 to 22 per cent over the period, while generation from both oil-fired and coal-fired plants is expected to decrease. Nuclear generation is expected to decrease from 10 per cent to 6 per cent in This document is based on information available in the fall of
