Land Area Estimate

To estimate the land area required for the proposed Cedar Flats Wind Project, a 220 MW industrial wind farm in South-West Oxford and Malahide, Ontario, we can rely on established research and industry standards for wind farm land use.
Land Area Estimate
According to a 2009 National Renewable Energy Laboratory (NREL) report, a modern wind farm in the United States requires approximately 34.5 hectares (ha) per megawatt (MW) of nameplate capacity, with a standard deviation of ±22.4 ha. To account for potential complexities in siting, a conservative estimate uses the mean plus one standard deviation, or 57 ha/MW. This figure includes both the direct footprint (turbines, roads, substations) and the surrounding lease or project area needed for spacing and environmental considerations.
 
For a 220 MW wind farm:
  • Calculation: 220 MW × 57 ha/MW = 12,540 hectares (approximately 30,987 acres).
  • Range based on standard deviation:
    • Lower bound: 220 MW × 12.1 ha/MW (34.5 – 22.4) = 2,662 ha (~6,578 acres).
    • Upper bound: 220 MW × 56.9 ha/MW (34.5 + 22.4) = 12,518 ha (~30,933 acres).
Another source suggests wind farms typically require 2 to 40 acres per MW, depending on terrain and turbine spacing, with open, flat terrain needing more land. For 220 MW, this translates to 440 to 8,800 acres (178 to 3,561 ha). However, only a small fraction of this land is directly used for infrastructure, with the rest often remaining available for agriculture.
 
Given the flat, agricultural landscape of South-West Oxford and Malahide, the higher end of these estimates is more likely due to the need for greater turbine spacing in open terrain. Thus, a reasonable estimate for the Cedar Flats Wind Project is around 12,000–13,000 hectares (29,652–32,123 acres) for the total project area, with only a small percentage (typically 1–5%) permanently occupied by turbines and infrastructure.
Contextual Considerations
  • Agricultural Impact: South-West Oxford and Malahide are prime agricultural regions in Ontario, known for crops like corn, soybeans, and wheat. A wind farm of this scale could disrupt thousands of acres of farmland, even if much of the leased land remains farmable. Construction activities, such as building access roads and turbine foundations, may compact soil, reducing crop yields.
     
  • Regulatory Requirements: In Ontario, wind farms must comply with the Ontario Building Code and municipal bylaws, including setback requirements (e.g., 550 meters from noise receptors like homes). These regulations may increase the total land area needed to meet spacing and zoning standards.
     
     
  • Comparison to Similar Projects: The Cedar Point Wind Farm in Colorado, a 252.3 MW facility, occupies about 20,000 acres (8,094 ha) of leased land, suggesting the Cedar Flats estimate is within a plausible range for a slightly smaller project.
     
Conclusion
The Cedar Flats Wind Project, with a capacity of 220 MW, is likely to require approximately 12,000–13,000 hectares (29,652–32,123 acres) of total project area in South-West Oxford and Malahide, based on conservative industry estimates. While only a small portion of this land will be permanently occupied by infrastructure, the project’s scale could significantly impact local agriculture and land use, given the region’s prime farmland. For precise figures, a detailed environmental assessment or project plan from wpd Canada would be needed, but such specifics are not publicly available as of April 24, 2025.
