Wind energy plays a crucial role in reaching global net-zero carbon emissions. So, countries worldwide are entering the technological and environmental race to achieve these goals.

Canada is one of the world leaders in producing and using renewable power due to its diversified geography with hydro, biomass, wind, and solar energy sources.

Wind Energy Industry in Canada

The regions in Canada spending the most on wind power projects over the next 10 years are Alberta, British Columbia, and Ontario.
The regions in Canada spending the most on wind power projects over the next 10 years are Alberta, British Columbia, and Ontario.

Although it is still early in the exploration of its vast wind energy resources, Canada has made rapid progress in this field and is now among the world's major producers. The area had about 14,304MW of installed wind energy capacity at the end of 2021.

In Canada, wind energy generates 3.5% of the nation's electricity, making it the second-most significant renewable energy source in the country.

Ontario, Quebec, and Alberta are the three provinces with the most wind power capacity.

To support clean energy, Canada is also making significant investments in new energy storage technologies. The cheapest and fastest-growing source of new electricity generation in Canada is wind energy. Over the past ten years, Canada has installed more wind energy capacity than any other country.

Market Overview

Due to the high-quality resources on its coasts and offshore, Canada has a lot of potential for offshore wind development, but none have been constructed to date.

7.7 percent of Canada's total electricity capacity is generated by onshore wind. Along with solar PV, wind energy is one of the renewable energy sources in Canada that is expanding the fastest. This is probably because wind energy is very scalable. With an installed capacity of 12,816 MW, Canada's onshore wind capacity increased from eight wind farms in 1998 to 299 in 2018. This is largely because Ontario, Alberta, and Quebec, the nation's top wind markets, have historically exhibited strong wind leadership.

Offshore wind policy is still being developed. The Canadian Energy Regulator Act (the Act), which took effect on August 28, 2019, now governs all aspects of the offshore wind industry in Canada. The implementation of this Act with regard to offshore renewable energy projects is supported by the Offshore Renewable Energy Regulations (ORER) initiative. A new mandate covering new energy developments, such as the regulation of offshore renewable energy, has been given to the National Energy Board, which is now also known as the Canada Energy Regulator.

The development of four offshore wind projects, one in each of the Atlantic provinces, has been announced by Atlantic Canada Offshore Developments (ACOD), despite the fact that no offshore wind farms have been constructed to date. Additionally, a 2020 press release from Northland Power Inc. confirmed the company's plans to acquire and develop an early-stage offshore wind project off the Pacific coast of Canada. The Atlantic, Pacific, and Gulf of Saint Lawrence coasts, as well as their surrounding areas, have a lot of potential for development.

Nova East Offshore Wind Farm

In Halifax, in April 2023, proponents unveiled the first proposed offshore wind farm for Nova Scotia.

By the end of the decade, Nova East Wind hopes to add 20 to 25 floating wind turbines to the province's Eastern Shore, 25 kilometers off Goldboro, and contribute up to 400 megawatts of electricity to the grid.

The project would account for about 20% of Nova Scotia Power's 2400 megawatts of current generating capacity.

The majority-owned SBM Offshore, an international provider of ocean energy services with headquarters in Amsterdam, and the Irish developer DP Energy formed the business together.

The project will cost between $1 billion and $1.5 billion, according to Ambroise Wattez, director of project development at SBM.

The electricity will replace energy currently produced by coal-fired plants owned by Nova Scotia Power, which must shut down by 2030, for domestic use. An underwater cable would carry the electricity along the ocean floor. The path follows a section of an abandoned offshore gas pipeline.

2. Blackspring Ridge Wind Project (Onshore)

Final Thouhts

In Canada, wind energy accounted for 5.97 percent of all electricity generated. Over the previous ten years, this number grew steadily.

The Canadian Renewable Energy Association reports that as of August 2022, 317 wind energy projects in Canada were generating power on a national scale. With 166 wind turbines, Black Spring Ridge in Vulcan County, Alberta, is the largest wind farm. For the next ten years, approximately 39 onshore and offshore wind power projects with a combined project value of USD 16 billion are planned.

The nation has been looking for chances and potential locations for new projects outside of its borders. The development of wind energy projects in Alberta is expected to attract about USD 8.3 billion in investment by 2030, making it an appealing market for investors in recent years. In addition to Alberta, huge investments are anticipated in Saskatchewan, where a 50% increase in renewable capacity is the province's goal for 2030.

The Lanfine Wind Project in Oyen's Special Area 3 in Alberta entered its final construction stage in October 2022 with the lifting and installation of the wind turbines in their final locations and the attachment of the blades to the rotors. In 2023, this new building is anticipated to be in use. The investment cost for the project is about USD 253.12 million.
