Market Snapshot: The cost to install wind and solar power in Canada is projected to significantly fall over the long term

In 2017, capital costs for utility-scaleFootnote 1 wind and solar projects in Canada were C$1600/kW and C$1800/kW (in 2016 dollars), respectively. These are estimated from costs published in other studies and include costs related to materials, equipment, labor, and development costs. Individual projects could have higher or lower capital costs depending on location in the country or project size.

The National Energy Board released Canada's Energy Future 2018 (EF2018) report in October 2018, which projects Canada’s energy supply and demand out to 2040. New in EF2018 are projections of the capital costs of utility scale wind and solar projects. In EF2018’s Reference Case, wind’s capital cost declines to C$1200/kW by 2040, while solar declines to C$1100/kW. In EF2018’s Technology case, capital costs decline faster, with wind falling to C$1000/kW and solar falling to C$650/kW. Costs decline for several reasons, including improved manufacturing efficiency, economies of scale, and lower installation costs as industry learns from experience.Footnote 2 EF2018’s Technology Case simply assumes technology improves faster than the Reference Case, resulting in a larger decline by 2040.

Description: This chart shows the capital cost of utility scale wind and solar projects in Canada from 2017 to 2040 under both the Reference and Technology Cases. In 2017, the capital cost for a utility scale wind and solar project in Canada was C$1600/kW and C$1800/kW, respectively. In the Reference Case, the capital cost of wind and solar declines to C$1200/kW and C$1100/kW, respectively. In the Technology case, wind falls to C$1000/kW and solar falls to C$650/kW by 2040.

Once built, power plants have operating costs, which are the costs of running projects. Because solar and wind power have no fuel costs, their operating costs are very low. This means capital costs are, by far, the most expensive part of building and running solar and wind projects. As capital costs for wind and solar continue to fall, they become increasingly competitive with fossil fuels in generating power, and will likely become greater sources of power generation in the years ahead.
