the Upper Midwest to consumers in the East. In 2017, Invenergy and GE announced plans for the $4.5 billion, 2,000 MW Wind Catcher (a/k/a Windcatcher) project on a 300,000-acre site in Cimarron and Texas counties in the Oklahoma Panhandle, which would have been among the world's largest wind farms when completed in 2020. AEP utility subsidiaries PSO and SWEPCO asked utility regulators in Louisiana, Arkansas, Texas and Oklahoma to approve plans to purchase the wind farm from Invenergy upon completion of construction. However, the project ran into opposition and was finally cancelled in July 2018. PSO was approved in early 2020 by regulators in Oklahoma to own a 45.5% share (675 MW) of a massive 1,485 megawatt wind project known as the North Central Energy Facilities ("NCEF"), with SWEPCO owning the remaining 810 MW. The project includes three wind farms covering areas in Alfalfa, Blaine, Custer, Kingfisher, Garfield, Major and Woods counties of Oklahoma. Approval followed in Arkansas and Louisiana in May; however, the Texas Public Utility Commission denied the plan for the 309 megawatts intended for that state. Nevertheless, PSO and SWEPCO decided to go forward with the project, with Oklahoma to receive 675 megawatts, Louisiana 464 megawatts, and Arkansas 268 megawatts. The projects were to be completed in the 2020-2021 timeframe. The NCEF project differed from the abandoned Wind Catcher plan in that Wind Catcher envisioned a new 765-kilovolt transmission line which would have run hundreds of miles in Oklahoma, while the NCEF facilities are near an existing PSO/SWEPCO transmission system. Also, NCEF was scalable, so that the states which approved the project could increase the number of megawatts allocated to them if/when another state rejected the proposal. The 199 MW Sundance project, located northwest of Aline in Woods County, was completed in April of 2021. The 287 MW Maverick and the 999 MW Traverse projects are scheduled to be in service later in 2021 and in early 2022, respectively. PATH Proposal In 2007, AEP teamed with Allegheny Energy to propose the US$1.8 billion (changed to US$2.1 billion in 2011) Potomac-Appalachian Transmission Highline (PATH), a , 765 kilovolt transmission line that would run through West Virginia, Virginia, and Maryland. According to Joe Denault, a volunteer spokesperson for the proposal, the PATH proposal would incorporate new technology to reduce carbon dioxide emissions by a year; allow for the transmission of renewable energy sources, such as wind, solar, and hydroelectric;
