TULSA, Okla. — A $4.5 billion wind farm and transmission line project is awaiting approval from Oklahoma regulators to fully qualify for federal tax credits for renewable energy.

The Oklahoman reports that the Wind Catcher project was announced by Public Service Co. of Oklahoma and a sister utility last week.

The Tulsa-based electric utility company is seeking pre-approval to recover its share of the costs from the project in the Oklahoma Panhandle, expected to go in service by 2020.

Nick Akins is the chairman and CEO of American Electric Power Co. Inc., PSO’s parent company. He says federal production tax credits are a key part of the project’s financing.

PSO hopes for a decision from the Oklahoma Corporation Commission by March 2018.
