Wind Turbines in Ontario, Canada

As of **2023–2024**, Ontario has approximately **2,300–2,400 utility-scale wind turbines** with **~5,900–6,000 MW** installed capacity.

Details

• Exact count: **2,297 turbines** (per IESO / CanWEA 2023 data).
• Capacity: **5,900+ MW** (nameplate).
• Generation: ~14–15 TWh/yr (~8–9% of Ontario demand).
• Rank: **#1 in Canada** (by capacity & generation). Quebec #2 (~4,000 MW).

Geography

• Southwest (Bruce, Huron, Lambton, Chatham-Kent, Essex): ~60% of capacity — best wind resource, transmission.
• Eastern (Prince Edward, Lennox & Addington, Frontenac): ~20%.
• Northern (Algoma, Manitoulin, Nipissing): ~15%.
• Offshore: **None** (Great Lakes moratorium since 2011).

Policy Context

• Green Energy Act (2009) drove boom (FIT program).
• Repeal (2019) + moratorium on new procurement.
• Recent: LT1 RFP (2023) — 2,000 MW new wind/solar/storage contracted. Growth resuming.

Ontario = Canada's wind leader, but expansion paused 2019–2023. Now restarting.
