|         Coal and Lignite: AEP’s public utility subsidiaries procure coal and lignite under a combination of purchasing arrangements including long-term contracts, affiliate operations and spot agreements with various producers and coal trading firms.  Electric demand experienced a slight increase in 2010 which resulted in a slight increase in coal and lignite tons consumed.  In response to continued lower consumption rates at certain locations during 2010, AEP continued to work with coal suppliers to better match deliveries with consumption and minimize the impact on fuel inventory costs, carrying costs and cash.  System wide, inventory levels were reduced by 11 days in 2010. |

|     The coal supplies at AEP System plants vary from time to time depending on various factors, including, but not limited to, demand for electric power, unit outages, transportation infrastructure limitations, space limitations, plant coal consumption rates, availability of acceptable coals, labor issues and weather conditions which may interrupt production or deliveries. At December 31, 2010, the System’s coal inventory was approximately 50 days of full load burn. |

|   | (2) AEP deducts equity compensation granted in stock units that are paid in cash, rather than AEP common shares, such as AEP's performance units and deferred stock units, from the number of shares available for future grants under the Amended and Restated American Electric Power System Long-Term Incentive Plan.  The number of shares available under this plan would be 1,185,633 higher if equity compensation that is paid in cash were not deducted from this column. |
