OG&E’s Commitment to Wind Energy (2007)
•
•
Make Oklahoma a national leader in renewable energy
Mission Accomplished!
•
•
•
•
Quadrupled OG&E’s wind power capacity by 2012
Increased transmission capacity to enable OG&E and others to deliver
wind-generated power from western Oklahoma to load centers
Provided OG&E communities and customers
choice of being up to 100% “green power”
users
Responsible development model: Executed
first two MOA’s with Wildlife Department
to offset wildlife habitat impacts.
