1. WIND PLANT SITING ISSUES Sam Enfield Atlantic Renewable Energy Corporation Wind Powering America 2 nd Mid-Atlantic Regional Workshop February 26, 2003 Philadelphia, Pennsylvania

2. ATLANTIC RENEWABLE Atlantic Renewable Developer of wind projects in the Eastern United States: 2000: 11.5 MW Madison (NY) PG&E Generating 2001: 15.0 MW Mill Run (PA) 9.0 MW Somerset (PA) 30.0 MW Fenner (NY) CHI Energy 2002: 66 MW Mountaineer (WV) FPL Energy 2003 & Beyond: >350 MW of projects under development in NY, PA and WV

3. The Mill Run Wind Power Project Ten 1.5 MW GE turbines Operational October 2001 ATLANTIC RENEWABLE

4. The Somerset Wind Power Project Six 1.5 MW GE turbines Operational October 2001

5. Distinct Ridgelines Forest Cover Population Density Previously Mined Wind Plant Site Characteristics in the Mid-Atlantic Region (Allegeheny Plateau) ATLANTIC RENEWABLE

6. Aesthetics Sound & Flicker Wildlife Impacts Avian Impacts Radio/TV Interference Sedimentation Wind Plant Siting Issues ATLANTIC RENEWABLE

7. Subjective – Most Do Not Find Them Objectionable, Some Do Use of Prominent Ridgelines Increases Visibility Visual Impact of Tree Clearing Aviation Warning Lights Haze – Visibility 1/3 to 1/4 of Historical – Sulfates the Major Factor Aesthetics ATLANTIC RENEWABLE

10. Sound & Flicker Typically an Issue Only for Receptors (Homes) Within 1500 Feet of Turbines Background Sound Levels Typically Low in Rural Areas Topography Can Shelter Receptors from Wind, Increasing Relative Contribution by Turbines ATLANTIC RENEWABLE

11. Wildlife Impacts Several Species of Possible Concern Indiana Bat Northern Flying Squirrel Others ATLANTIC RENEWABLE

12. Avian Impacts Little Experience with Wind/Avian Issue in Region Concern that Appalachian Ridges Constitute Major Migration Pathways, thus Pose Risk to Migrating Raptors and Songbirds Studies Do Not Indicate Major Migration Use Migration Not Correlated with Risk ATLANTIC RENEWABLE

13. Radio/TV Interference Licensed Transmission Pathways Legally Protected Greater Population Density (than West) Increases Likelihood of Interference Competition for Elevated Sites ATLANTIC RENEWABLE

14. Sedimentation “Most serious form of water pollution in mountainous West Virginia” Greater rainfall (than West) generates more runoff, but also supports more vegetation ATLANTIC RENEWABLE
