The Oklahoma Corporation Commission voted 3-0 to approve Crossroads, a Dewey County wind project being developed by investor-owned utility Oklahoma Gas & Electric (OG&E).
Crossroads will be at least 197.8MW, but could be up to 227MW, depending on the results of a transmission study by regional transmission organisation the Southwest Power Pool.
The wind farm will connect to OG&E’s Windspeed transmission line to Oklahoma City, which came online this year.
Crossroads will use Siemens 2.3MW turbines and will be constructed by RES Americas.
OG&E said the turbines will start coming online in the second half of 2011, and the wind farm will reach full production in 2012.
The project will raise OG&E’s wind capacity to at least 750MW, about 10% of its total capacity.
The company has said it will not add any fossil fuel generation onto its system until 2020.
OG&E serves about 779,000 customers in Oklahoma and western Arkansas.
