COLUMBUS, Ohio, April 29, 2010 – American Electric Power (NYSE: AEP) today reported 2010 first-quarter earnings, prepared in accordance with Generally Accepted Accounting Principles (GAAP), of $344 million or $0.72 per share, compared with $360 million or $0.89 per share in first-quarter 2009. Ongoing earnings (earnings excluding special items) for the quarter were $365 million or $0.76 per share, compared with $360 million or $0.89 per share in first-quarter 2009.

The per-share results for first-quarter 2010 reflect the dilutive effect of additional shares outstanding issued during 2009, which reduced ongoing earnings by $0.13 per share compared with first-quarter 2009.

For the quarter, GAAP earnings were $21 million lower than ongoing earnings because the enactment of the federal Patient Protection and Affordable Care Act brought an unfavorable change to the tax treatment of post-employment health care costs associated with the future reimbursement of Medicare Part D retiree prescription drug benefits.

A full reconciliation of GAAP earnings with ongoing earnings for the quarter is included in tables at the end of this news release.

“We had strong results for the first quarter because of successful rate proceedings, increased off-system sales and favorable weather,” said Michael G. Morris, AEP chairman, president and chief executive officer. “For several quarters we’ve been seeing some signs of economic improvement in the states that we serve, but the signs have yet to be followed by a broad increase in electricity demand that typically accompanies economic improvement. Residential electricity sales have improved year on year. Industrial sales are down slightly from first quarter last year, but we are no longer seeing the steep declines experienced throughout 2009. Commercial sales continue to struggle.

“In light of the slow recovery of electricity demand and depressed wholesale prices, we are taking further meaningful steps to reduce our costs,” Morris said. “These steps include non-labor and labor reductions such as an offer of a voluntary severance package.

“As always, our top priorities are maintaining reliable service for our customers, a safe work environment for our employees and our commitments to our shareholders.”

EARNINGS GUIDANCE

AEP reaffirmed its ongoing guidance range for 2010 of between $2.80 and $3.20 per share. “The additional cost-reduction measures have allowed us to keep our 2010 earnings guidance unchanged,” Morris said.

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.

Ongoing earnings from Utility Operations increased by $19 million during first-quarter 2010 compared with the same period in 2009. The improvement was driven by higher retail margins because of successful rate proceedings, the effects of favorable weather and higher margins for both off-system sales and transmission revenues. These increases were somewhat offset by lower sales to AEP’s commercial and industrial customers, higher operating expenses and the 2009 receipt of the Donald C. Cook Nuclear Plant accidental outage insurance.

Results for AEP’s River Operations were lower in first-quarter 2010 compared with the same period in 2009 primarily because of reduced grain loadings, higher fuel and other operating expenses and the gain on sale of two towboats in 2009.

Generation and Marketing, which includes AEP’s non-regulated generating, marketing and risk management activities in the Electric Reliability Council of Texas (ERCOT) market area, decreased $14 million in first-quarter 2010 compared with the same period in 2009 because of lower gross margins from marketing activities.

All Other, which includes the Parent Company and other investments, was favorable by $7 million in first-quarter 2010 compared with the same period in 2009 primarily because of lower expenses.

Retail Sales – The improvement in retail gross margins reflects the favorable results from regulatory proceedings in multiple jurisdictions and increased residential usage driven by favorable weather in the quarter. These increases were somewhat offset by lower sales to commercial and industrial customers than in the same period last year. First-quarter heating degree days were 9 percent above normal and 4 percent higher than in the same period last year in AEP’s eastern service territory. In AEP’s western service area, heating degree days were 32 percent higher than normal and 48 percent higher than in the same period last year. The favorable weather increased margins in the quarter by $37 million.

Off-System Sales – Gross margins from Off-System Sales increased $12 million for first-quarter 2010 primarily because of higher physical sales volumes in our eastern territory, which reflects favorable generation availability.

Transmission Revenues – Transmission revenues were higher than in the same period last year primarily because of increases in the Southwest Power Pool, ERCOT and PJM Interconnection regions.

Other Operating Revenue – The decrease in Other Operating Revenue during first-quarter 2010 from the prior year is primarily because of the receipt of the Cook Nuclear Plant accidental outage insurance proceeds in 2009 and lower gains on the sale of allowances.

Operations & Maintenance Expense – O&M expenses in first-quarter 2010 were $32 million higher than in the prior year, but expenses net of revenue offsets were $14 million higher than in the prior period.

Depreciation & Amortization – The increase in Depreciation & Amortization in first-quarter 2010, compared with the prior period, primarily is attributed to an increase in plant balances.

Interest Expense & Preferred Dividends – The increase in Interest Expense during first-quarter 2010 compared with the same period in 2009 is primarily because of an increase in long-term debt and a decrease in the debt component of Allowance for Equity Funds Used During Construction (AFUDC) due to lower Construction Work in Progress balances at Appalachian Power Company and the Ohio Companies.

Other Income & Deductions – The increase over the same period in 2009 is primarily because of an increase in AFUDC for the J. Lamar Stall and John W. Turk plants under construction at Southwestern Electric Power Company.

American Electric Power is one of the largest electric utilities in the United States, delivering electricity to more than 5 million customers in 11 states. AEP ranks among the nation’s largest generators of electricity, owning nearly 38,000 megawatts of generating capacity in the U.S. AEP also owns the nation’s largest electricity transmission system, a nearly 39,000-mile network that includes more 765-kilovolt extra-high voltage transmission lines than all other U.S. transmission systems combined. AEP’s transmission system directly or indirectly serves about 10 percent of the electricity demand in the Eastern Interconnection, the interconnected transmission system that covers 38 eastern and central U.S. states and eastern Canada, and approximately 11 percent of the electricity demand in ERCOT, the transmission system that covers much of Texas. AEP’s utility units operate as AEP Ohio, AEP Texas, Appalachian Power (in Virginia and West Virginia), AEP Appalachian Power (in Tennessee), Indiana Michigan Power, Kentucky Power, Public Service Company of Oklahoma, and Southwestern Electric Power Company (in Arkansas, Louisiana and east Texas). AEP’s headquarters are in Columbus, Ohio.

AEP’s earnings are prepared in accordance with accounting principles generally accepted in the United States and represent the company’s earnings as reported to the Securities and Exchange Commission. AEP’s management believes that the company’s ongoing earnings, or GAAP earnings adjusted for certain items as described in the news release and charts, provide a more meaningful representation of the company’s performance. AEP uses ongoing earnings as the primary performance measurement when communicating with analysts and investors regarding its earnings outlook and results. The company also uses ongoing earnings data internally to measure performance against budget and to report to AEP’s board of directors.
