  1. OPEN HOUSE Public Information Centre #2 February 27 & 28, 2013

  2. Overview • Invenergy Canada • Renewable Energy Approval(REA) process • Project details • Construction process • REA summary • Next steps

  3. Invenergy Profile • North America’s largest independent wind developer • 8,000+ landowners • Developed and placed into service 33 wind farms across the United States, Canada and Europe, totalling over 3,000 megawatts • Developer and operator of Raleigh Wind Energy Centre, a 78 megawatt project in Chatham-Kent, ON • Canadian offices in Toronto and Montreal, head office in Chicago, regional offices throughout the USA and in Europe

  4. REA Process 2nd Public Information Centre (PIC) Address Stakeholder Concerns Finalize REA Reports REA Submission to MOE MOE Posting & Decision Period Final Public Review REA Decision

  5. Conestogo Wind Energy Centre Project details • 69 megawatt project • 26 maximum turbines located in North Perth and Perth East • Substation located in the Township of Wellesley (Steed and Evans) • 20 year power purchase contract with the Ontario Power Authority

  6. How a wind farm works Rotating generator converts kinetic energy of the wind into electrical energy Transformer increases voltage for transmission to substation Substation increases voltage for transmission over long distances Transmission to grid 2 3 Source: The Canadian Wind Energy Association

  7. Construction Process • Survey and consult • Clear and grade • Install road • Dig foundation • Place rebar and anchor bolts • Pour foundation • Backfill foundation • Dig trench for collection line • Lay collection line • Repair drain tile • Delivery of turbine components • Prepare for turbine assembly • Erect tower, hub and rotor blades • Field reclamation • Decompaction of affected soil • Commission turbine Reclaimed laneway

  8. Foundation Construction Excavation and Seal Slab

  9. Foundation Construction Rebar and Concrete Base Pour

  10. Foundation Construction Base and Pedestal

  11. Foundation Construction Backfilling

  12. Collector Line Construction Installation overview

  13. Underground Collection System Cable supply moves in front of installation crew

  14. Underground Collection System Steps 1 & 2 – trenching machine excavates trench and places cables in trench

  15. Underground Collection System Option – Horizontal Directional Drilling is used for public roads and/or water crossings, or significant natural features

  16. Underground Collection System Step 3 – small dozer follows behind trencher to backfill trench using compacted native fill

  17. Underground Collection System Finished trench view

  18. Repair Tile

  19. Deliver Tower Section & Blade

  20. Erect Tower, Hub and Rotor Blades

  21. Commission Turbine

  22. REA Summary - Mitigation measures in place for construction impacts Spills • A spills response plan has been developed to contain and clean-up all spills without unnecessary delays and to notify the appropriate authorities, including the MOE and local municipalities. Erosion/Stormwater runoff • Erosion and sediment control measures will be used to prevent sedimentation loading of local surface water bodies. Land compensation • Landowners will be compensated for temporary loss of land used for harvesting of agricultural crops. Particulate matter • Dust control methods will be used to suppress particulate matter. Noise and safety from heavy equipment • Work with all community members including Mennonite representatives regarding notification and procedures for construction activities .

  23. REA Summary - Mitigation measures in place for operational impacts Emergency Response • An emergency response and communication plan (ERCP) will be in place during operation. Increased Light • All turbines will be equipped with Transport Canada and NAV CANADA Safety lighting. Lighting will be synchronized to flash simultaneously on all turbines. Waste • Generated solid waste and hazardous waste (e.g. oils, lubricants, paints) will be collected and disposed of at licensed off-site waste management facilities. Public Safety • Turbines will be monitored 24/7 to determine if ice build-up is occurring on the turbine. Turbines would be shut down in the event of excessive ice build-up. Foundations and turbines will be built to withstand a category 2 tornado. • Discuss with snowmobile club on notification and mitigation measures Road Traffic • Heavy equipment may be required infrequently to maintain the turbines and would follow designated transportation routes to access the turbine sites.

  24. REA Summary - Noise Study • The noise assessment was completed in accordance with the Ontario Ministry of the Environment (MOE) “Noise Guideline for Wind Farms” (Oct. 2008). • Results of the noise study indicate that the wind turbines will produce sound levels at receptor locations that are no greater than 40 dBA. • The project substation will meet the 40 dBA noise limit.

  25. REA Summary - Natural Heritage The results of the Natural Heritage Studies found that: • Seven significant Amphibian Breeding Habitat was identified within 120 meters of the project location; • 33 woodlands within 120 meters of project components have been identified as significant; • 11 wetlands within 120 meters of project components have been identified as provincially significant; and, • No Areas of Natural or Scientific Interest (ANSI), Provincial Parks or Conservation Reserves are within the study area.

  26. Electromagnetic Fields (EMF) • Every time someone uses electricity they encounter EMF at extremely low frequencies. Health Canada (2010) stated that: “On a daily basis, most Canadians are exposed to EMF generated by household wiring, fluorescent lighting and any electrical appliance that plugs into the wall, including hair dryers, vacuum cleaners and toasters”. • For some Canadians this also includes exposure to EMF from high voltage power lines and transformer boxes. Health Canada (2010) has also stated: “When you are indoors at home, the magnetic fields from high voltage power lines and transformer boxes are weaker than those from household electrical appliances”. • Invenergy will construct the project collector system to meet Provincial Electrical standards. The collector lines will be buried which reduces EMF levels.

  27. Stray Voltage • Recognize concern and sensitivity in the community. • The Conestogo Wind Project will be constructed to all applicable codes and standards. • Perth County has recommended that Invenergy works with Hydro One to determine how additional load requirements related to this project have any impact on stray voltage • Hydro One and the Ontario Energy Board protocols in place to address existing stray voltage concerns.

  28. Next Steps February 2013 • Public Information Centre #2 (60 days after release of draft REA documents) Spring 2013 • Submit REA application to the Ministry of the Environment Late 2013/Early 2014 • Construction start Project Updates • Please contact Mr. Richard Deacon (519) 365-4180

  29. For more information • Further comments on the REA reports can be submitted to: Dillon Consulting Ministry of Environment conestogo@dillon.caREFO@ontario.ca • Keep informed of project updates and provide input on project decisions – join the project working group. Interested community members are encouraged to contact conestogo@dillon.ca.
