US electric utility American Electric Power (AEP) is proceeding with its $2bn North Central wind power complex in Oklahoma despite a high-profile failure to win regulatory approval in Texas where a subsidiary planned to deliver 309MW of capacity to state customers.

The near-1.5GW North Central will comprise a trio of wind farms: the 999MW Traverse, the nation’s second largest single-site onshore project under construction, as well as 287MW Maverick and 199MW Sundance.
