The company did not say when the unit would return to service.
The 1,584-MW Welsh plant is located in Cason in Titus County about 130 miles (209 km) east of Dallas. The station has three 528-MW units, which entered service in 1977, 1980 and 1982.
One MW powers about 500 homes in Texas.
AEP's Southwest Electric Power Co subsidiary owns and operates the station.
