The wind farm would have used 800 GE wind turbines.

American Electric Power (AEP) is canceling its proposed $4.5 billion, 2,000 megawatt Wind Catcher project, citing the Public Utility Commission of Texas’ July 26 decision to deny approval of the project.

The project had been approved by the Arkansas Public Service Commission, Louisiana Public Service Commission, and Federal Energy Regulatory Commission. A decision was pending at the Oklahoma Corporation Commission.

The utility said that it needed "timely approvals" from a number of regulatory authorities in order to finish the project by the end of 2020 and take advantage of all available federal production tax credits.

Texas regulators unanimously decided that the project did not offer enough benefits for Texas ratepayers. Chicago-based Invenergy LLC was developing the project in Oklahoma.

In February, that state's attorney general and a state administrative law judge concluded that AEP failed to prove there was an economic need for the project and that it left customers facing too much risk.

The project scope as outlined in AEP's July 2017 proposal included a 350-mile-long extra-high-voltage power line to deliver the renewable energy to customers. AEP's utility subsidiaries Public Service Co. of Oklahoma and Southwestern Electric Power Co. would receive electric power from the wind farm.

SWEPCO was to own 70 percent of the project, including 1,400 MW of wind. PSO would own 30 percent, including 600 MW of wind.

Wind Catcher would have used 800 GE 2.5 MW turbines. GE would also use its Digital Wind Farm system, providing software to support wind operations, including asset performance management and operations optimization. All machine heads and hubs would have been made in the U.S., and additional components would have been sourced from Louisiana, Arkansas, Texas and Oklahoma.
