COLUMBUS, Ohio, Feb. 28, 2012 – AEP Ohio, a unit of American Electric Power (NYSE: AEP), filed today with the Public Utilities Commission of Ohio (PUCO) new proposed tariffs that continue the provisions, terms and conditions of the company’s previous Electric Security Plan (ESP) as ordered by the PUCO on Feb. 23.  The new tariffs reflect the full cost of fuel, carrying costs for environmental investments, the remaining cost of fuel charges deferred and capped in previous years, and the removal of riders previously approved under the stipulated agreement. The new rates, once approved by the PUCO, will have varying impacts for customers. Many customers will see slightly lower rates, while some customers, particularly industrial and manufacturing customers, will see increases.

          Today’s filing proposes rates and tariffs for two rate zones to reflect the pre-merger service territories of Ohio Power and Columbus Southern Power (CSP). As ordered, rates for all customer classes will return to rates charged as of December 2011. Due to the elimination of the stipulation agreement, rates charged to customers in the Ohio Power rate zone will include the portion of the actual cost of fuel used in previous years, but deferred for later cost recovery.

           For the average residential customer in the Ohio Power rate zone using 1,000 kilowatthours (kWh) per month, approval of the rates would result in a decrease in a customer’s total monthly bill of approximately $1.78 or 1.5 percent compared to bills charged in January and February of this year. For the average residential customer in the CSP rate zone using 1,000 kWh per month, approval of these rates would result in a decrease of approximately $5.37 or 4.3 percent from when compared to January and February 2012. These averages are based on customers who receive their generation, transmission and distribution service through AEP Ohio. Estimates cannot be given for any customer who has selected a competitive retail generation supplier. Actual percentage changes in bills will vary for individual customers depending on their energy usage.
