History
Originally known as Mayflower, the community was renamed Oklaunion around 1888 by Joseph S. "Buckskin" Works.[2] The reason behind the name change was an attempt to attract the Frisco line to the community so that it would connect with the Fort Worth and Denver City Railway. Nearby Vernon was chosen as the site for the linkage, however, but Oklaunion prospered as a stop on the Fort Worth and Denver City line.[3] A post office was established in 1889 and a school opened during the mid-1890s.
The community voted to incorporate on June 6, 1928.[2] In 1930, the town had a population of 254. That figure fell to 223 in 1940 and 129 by 1950. Sometime after, the town dissolved its incorporation. The population had fallen to fewer than 140 in 1990 and remained at that level by 2000.
Although Oklaunion is unincorporated, it has a post office with the zip code of 76373.[5]

Since 1984 there has been a back-to-back HVDC station at Oklaunion which was built by General Electric. It works with a voltage of 345 kV and has a transfer rate of 220 megawatts.
The plant was scheduled to be shut down in September 2020. The reason was high cost to keep the emissions at levels acceptable. The plant was bid on and won by Frontier Energy. They will convert the plant to natural gas, a cleaner burning fossil fuel.
