OG&Es Commitment to Wind Energy (2007) Make Oklahoma a
national leader in renewable energy Mission Accomplished!
Quadrupled OG&Es 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 MOAs
with Wildlife Department to offset wildlife habitat impacts.

Next Gen Technology - Crossroads Siemens SWT 3.0 101 Rated 3.0
MW Same specs as the 2.3-101, but with 50% fewer moving parts. No
gearbox, uses a direct drive system. OG&E first to install this
model in the U.S.
