TULSA, Okla., May 29, 2008 – Public Service Company of Oklahoma (PSO), a subsidiary of American Electric Power (NYSE: AEP) has named Gary Knight vice president for Generating Assets.  The promotion came as AEP named seven leaders to new power generation posts. 

The formation of these new positions results from a six-month study and reflects the utility company’s efforts to better align power generation with operating companies’ budgetary and regulatory systems.

"This structure takes us closer to the operating company model where we move more operations closer to the customer and to the regulator. This step will increase collaboration and shared accountability between various operations within each state regulatory jurisdiction," explained Mike Morris, chairman, president and chief executive officer.
Knight has spent the majority of his career in power generation at PSO, first joining the payroll in 1981.  He served most recently as director of generation.

Knight earned his bachelors degree in mechanical engineering at the University of Tulsa.  He is a registered professional engineer in Oklahoma, a member of the American Society of Mechanical Engineers and a commissioned inspector of the National Board of Boiler & Pressure Vessel Inspectors.  He and his wife Lisa have been married for 26 years and have two children.
