Wind Turbines and Neighbours

  1. 1. Wind Turbine Impacts on NeighboursCommunity Information Meeting April 3, 2013
  2. 2. Wind Turbine Impacts on Neighbours• Topics – Shadow Flicker – Ice Throw – Fire/High Angle RescueApril 3, 2013 Elma-Mornington Concerned Citizens
  3. 3. Shadow Flicker• Intermittent shadows cast by a moving object Daily Impact  20 – 30 minutes depending on distance  Sunrise or sunset depending on location• Extremely annoying  Interrupts sleep or evenings outdoors  Difficult to block as caused by a very tall object  Autistic children are extremely sensitiveApril 3, 2013 Elma-Mornington Concerned Citizens
  4. 4. European RegulationGermany 30 hours/year or 8hours/year with cloud coverEngland 30 hours/yearN. Ireland 30 hours/yearBelgium 30 hours/yearIreland 30 hours/year + 30 minutes/day or 10 blade diameter setbackScotland 10 blade diameter setbackSpain Regulation not necessaryThe Netherlands 5 hours 40 minutes/yearDenmark 10 hours/year with appropriate cloud coverCanada/USA No regulation • Simpler definition recommended most of these definitions need detailed assessments to determine compliance Note: 30 Hours per Year = 60 to 90 days per yearApril 3, 2013 Elma-Mornington Concerned Citizens
  5. 5. Area Affected by Shadow Flicker Turbine . 8 Blade Diameters 135° West 135° EastApril 3, 2013 Elma-Mornington Concerned Citizens
  6. 6. Amherst Island Wind Project Noise and Potential Shadow Flicker Blue arcs show a radius of 8 blade diameters (0.9 km) and extend 125 degrees east and west of north.April 3, 2013 Elma-Mornington Concerned Citizens
  7. 7. Municipal By-law Proposed• North Perth developing a by-law to regulate shadow flicker  Prohibit all moving shadows beyond the property owned by originating landowner  No allowances for any shadow flicker  Using ongoing municipality’s power to regulate ‘public nuisances’  Enforcement triggered by complaint Draft coming to Council on April 8April 3, 2013 Elma-Mornington Concerned Citizens
  8. 8. Fire Safety • Fire do happen in wind turbines • Project located in a high density rural area and insufficient separation presents risk to: – Homes – Farm buildings/equipment – Crops/forests • Invenergy has provided no detailed emergency plans. Call 911 service or James Murphy in Toronto • North Perth requested a realistic plan to address fires in turbinesApril 3, 2013 Elma-Mornington Concerned Citizens
  9. 9. Burnt Turbine North Of GoderichApril 3, 2013 Elma-Mornington Concerned Citizens
  10. 10. Invenergy California Ridge TurbineApril 3, 2013 Elma-Mornington Concerned Citizens
  11. 11. High Angle Rescue• Turbines are work places where accidents and health incidents will occur and ‘High angle rescue’ services are needed to extract people from these locations• Not available in North Perth or Perth East; and delivery from urban centres will not meet required response times• Not realistic to upgrade local emergency services to deliver services.• North Perth requested a realistic plan to address high angle rescue plan for the turbinesApril 3, 2013 Elma-Mornington Concerned Citizens
  12. 12. Ice Throw From Turbine Blades• Dr. John Harrison, Queens University – “Consultant models make no sense” • Ice does not come away in cube shapes • The drag force does not act on the front face • The amount of ice is under-estimated• Modeled Realistic Conditions – Ice in thin sheets – Sheet aligns with speed relative to the air – Drag force acts over the plane surfaces – Drag force opposes the relative motion – There is a wind-speed gradientApril 3, 2013 Elma-Mornington Concerned Citizens
  13. 13. Projected Maximum Ice Throw Results Parallel Safety Zones Recommended by Equipment ManufacturersApril 3, 2013 Elma-Mornington Concerned Citizens
  14. 14. Ice Throw Concerns• Ice throw will happen and will affect snowmobilers and hunters using properties around turbines• Automated shutdown triggered after ice thrown from one blade• Provincial standard insufficient – 10 metres plus blade length = 60 meters from property lines• Equipment manufacturer specify safety zones of about 450 metres – extend beyond leased property• Safety plan requested to address issue throw• Issue can be raised by neighbouring property ownersApril 3, 2013 Elma-Mornington Concerned Citizens
