Pillar Mountain Wind Project
Pillar Mountain and Terror Lake Hydroelectric Facility
• Terror Lake Works like a battery• Lowers fuel costs• Stabilizes power costs• Lowers Emissions
Load Variability
•Approximately 98% availability
•28,472,822 kWh generated since July 2009
•2,005,128 gallons of diesel saved
•22,559 tons of CO2 saved
Net Savings to CommunityAt $3.30 per gallon for diesel,
approximately $4.5 million net savings.
