Wind Speeds
“Class 3” Turbines
• Taller towers (80-100m) • Longer blades (~50m) • Advanced design/
materials
GE 100-1.6 MW 7.5 m/s wind = 53% CF

WIND AND WATER POWER PROGRAM
Wind PPA Prices Generally Have Been Falling Since 2009 and Now Rival Previous Lows Set a Decade Ago (this despite the trend to lower-quality wind resource sites)
