(NYSE:TGN), a majority-owned subsidiary of CenterPoint Energy, Inc. (NYSE: CNP), voted to exercise its right of first refusal to purchase up to the entire 25.2 percent interest in the South Texas Project Electric Generating Station (STP) that is currently owned by American Electric Power (AEP). In addition to AEP, the 2,500 megawatt nuclear plant is owned by Texas Genco (30.8 percent), City Public Service of San Antonio (CPS) (28 percent) and Austin Energy (16 percent). AEP had previously announced that it had received an offer of $333 million, subject to certain adjustments, to purchase its 630 megawatt interest.

Austin Energy indicated that it will not exercise its right of first refusal, while CPS indicated that it intends to purchase at least 12 percent or 300 megawatts.
