The lights are big and bright deep in the heart of the Lone Star State, thanks to AEP Texas Central (TCC). The utility, formerly named Central Power and Light, provides regulated electric utility services to 766.000 customers in its 100,000 sq. ml. service territory in south and west Texas. TCC operates more than 29,600 miles of transmission and distribution lines in Texas; its transmission assets are managed by ERCOT. In addition to distributing power, AEP Texas also reads electric meters. maintains and repairs power lines, and takes care of connections and disconnections.
TCC's service territory includes the southern portion of Texas from just south of San Antonio to the Mexican border and from Bay City west to Eagle Pass. Major cities served include Corpus Christi, McAllen, Harlingen, Laredo, and Victoria.
At one time, more than half of its revenues came from wholesale power transactions, but parent American Electric Power has divested the unit's generation assets to make it a pure transmission and distribution company. TCC has sold its stake in STP Nuclear (STP) to STP, NRG Texas, and the city of San Antonio.
