Canada sets first offshore wind areas towards massive goals

Nova Scotia is looking for 40GW off its windswept coastlines as US New England states sniff around for power

The Canadian province of Nova Scotia together with the federal government have set the nation’s first offshore wind areas towards a proposed 40GW sector goal.

The four areas selected are slated to be auctioned off in Canada’s first offshore wind leasing round for 5GW, potentially this year.

“With some of the top wind speeds in the world, Nova Scotia has the potential to become a clean energy superpower,” said provincial premier Tim Houston.

“With the right infrastructure, we’ll have the opportunity to send our wind west to power other parts of Canada. By becoming an energy exporter, we can secure long-term prosperity for Nova Scotians.”

Earlier this year Houston broached a dramatic, eightfold increase of its offshore wind goals to 40GW in response to Prime Minister Mark Carney’s aim to transform Canada into an “energy superpower”.
Sector development in Nova Scotia is particularly promising due to strong winds averaging 10-12 metres per second and mostly shallow seabed that allows for fixed bottom development well out of eyeshot, eliminating viewshed concerns.

While Canada’s Atlantic wind resources are unquestioned, development faces significant hurdles, most glaringly lack of route-to-market.

“The key trouble is figuring out a way to convert these electrons into something we can sell,” said Dawn MacDonald, global offshore wind market sector leader for Texas-based infrastructure consultancy Aecom.

The two Atlantic provinces spotlighted for offshore development – Nova Scotia and Newfoundland & Labrador – have only around 1.5 million residents combined and low power demand. Nova Scotia's 40GW target would generate nearly 30% of Canada's entire power demand.

Selling this electricity to the power-hungry US Northeast states via a massive subsea cable has also been advanced by the New England-Maritimes Offshore Energy Corridor (NEMOEC) coalition that includes Canadian offshore wind developer Northland, along with Hexicon and TotalEnergies.

New England states and New York had planned on offshore wind to drive their clean energy and climate ambitions, but development has flagged under President Donald Trump’s efforts to derail the sector along with stubbornly high costs.

Canadian deepwater harbours are already serving the US sector, with the ports of Halifax and Argentia marshalling massive components made in Europe for Orsted's New England arrays and Copenhagen Infrastructure Partners-Avangrid's Vineyard Wind.

Massachusetts has already been spotlighted as a potential market for Canadian offshore wind power.

As reported by Canada’s National Observer, Maria Hardiman, spokesperson for the Massachusetts Executive Office of Energy and Environmental Affairs, said her department is now in “regular communication” around developing “new energy sources,” that could include Canadian offshore wind.

Northeast states, including the New England region and New York, are actively broadening transmission ties with their northern neighbour to access its vast hydropower sector.

New England states and Canada’s eastern Maritime provinces have also entered into anagreement to bolster each other’s industries.

“Building on our efforts to connect our regions through transmission, there are significant opportunities to construct new onshore and offshore wind projects across Canada and the [North American] northeast,” Hardiman said.

After the first tender is concluded, four other areas identified in the January 2025 regional assessment of offshore wind development will be revisited, the government added.
