AEP Expects First-Quarter GAAP and Ongoing EPS of Approximately $0.68

COLUMBUS, Ohio, April 19 /PRNewswire-FirstCall/ -- American Electric Power today said that it expects first-quarter 2007 earnings, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and first- quarter 2007 ongoing earnings (earnings excluding special items) of approximately $0.68 per share. First-quarter 2006 GAAP earnings were $0.97 per share and first-quarter 2006 ongoing earnings were $0.96 per share.

AEP anticipated the decline in ongoing earnings for the quarter, when compared to the prior period, because of the expected earnings impact of the scheduled completion of environmental retrofit projects at two large coal- fired plants and the reduction in earnings contribution from three items that contributed to earnings in 2006.

"All in all, we believe that 2007 is off to a solid start, and we are quite encouraged by the success of the retrofit projects," said Michael G. Morris, AEP's chairman, president and chief executive officer. "After the retrofits, plant performance from both a production and an environmental perspective has been excellent."

Environmental retrofits at the plants were completed in the quarter as scheduled. The retrofit projects, which installed additional emissions reductions systems, improve AEP's fuel procurement flexibility by decreasing the company's need for higher-cost low-sulfur coal. The projects, which increased operating and maintenance expenses when compared to the prior period, temporarily reduced the amount of generating capacity available in the first quarter. This reduction in available capacity, combined with the growth in utility sales to meet native load demand, brought an expected decrease in off-system sales opportunities in the quarter. The decline in off-system sales was partially offset by the increased utility sales and expanded utility gross margin, a result of rate relief achieved in a number of jurisdictions during the second half of 2006.

AEP has now completed environmental retrofits on approximately 90 percent of the 3,340 megawatts of generating capacity scheduled to receive selective catalytic reduction systems to reduce emissions of nitrogen oxides and more than 40 percent of the 6,740 megawatts of generating capacity scheduled to receive flue gas desulfurization systems to reduce emissions of sulfur dioxide.

AEP planned for an approximately $0.20 per share decline in first-quarter 2007 ongoing earnings from items that contributed to the 2006 results but would be reduced or absent in 2007. The items were:

* Elimination of the Seams Elimination Charge Adjustment, or SECA rates, that contributed to transmission gross margin in 2006 but ended on April 1, 2006, in various AEP jurisdictions in the East; the rates were put into place in December 2004 by the Federal Energy Regulatory Commission to offset the loss of through-and-out rates brought by a change in the commission's authorized tariffs. * A reduction in the earnings-sharing payment from Centrica, the final payment from AEP's participation in a multi-year earnings-sharing mechanism established in 2002 when AEP sold its Texas retail electricity providers to Centrica. * The reduction in gross margin from a sale of emissions credits that contributed to first-quarter 2006 earnings. "With emissions credits, we're opportunists and not regular market participants," Morris said. "We sold credits last year when we saw an opportunity to take advantage of incredibly high prices in the marketplace. We did not expect that opportunity to be repeated this year."

AEP, which will release first-quarter earnings details on Thursday, April 26, reaffirmed its ongoing guidance range for 2007 of between $2.85 and $3.05 per share. In providing ongoing earnings guidance, there could be differences between ongoing earnings and GAAP earnings for matters such as, but not limited to, divestitures or changes in accounting principles. AEP management is not able to estimate the impact, if any, on GAAP earnings of these items. Therefore, AEP is not able to provide a corresponding GAAP equivalent for earnings guidance.
