Evansville, Ind. -- Vectren Corporation (NYSE: VVC) today announced that on March 9, 2011, its subsidiary, Vectren Utility Holdings, Inc., ("VUHI") priced $150 million of its senior unsecured notes to be issued in three tranches of 10, 15 and 30 years.  The notes were sold to various institutional investors through the private placement market.

Subject to the satisfaction of customary closing conditions, the notes will be issued on or about Nov. 30, 2011.
