Item 8.01. Other Events.

For information regarding the development by Southern Power and OUC of an IGCC project in Orlando, Florida at OUC’s Stanton Energy site and the evaluation of potential impacts of proposed federal and state legislation and regulation on the gasifier portion of the IGCC project, see MANAGEMENT’S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – “Construction Projects—Integrated Coal Gasification Combined Cycle (IGCC)” of Southern Power in Item 7 and Note 4 to the financial statements of Southern Power under “IGCC” in Item 8 of the Annual Report on Form 10-K for the fiscal year ended December 31, 2006 and MANAGEMENT’S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – “Integrated Gasification Combined Cycle (IGCC) Project” and – “Environmental Matters – Florida Greenhouse Gas Executive Orders” of Southern Power and Note (B) to the Condensed Financial Statements of Southern Power under “Integrated Gasification Combined Cycle (IGCC) Project” in the Quarterly Report on Form 10-Q for the quarter ended September 30, 2007.

On November 13, 2007, Southern Power and OUC mutually agreed to terminate construction of the gasifier portion of the IGCC project. Southern Power will continue construction of the gas-fired combined cycle generating facility at the Stanton Energy

site. Southern Power expects to record in the fourth quarter of 2007 an estimated impairment loss of approximately $50 million pre-tax ($30 million after tax), which includes future cash expenditures of approximately $30 million, related to cancellation of the gasifier portion of the IGCC project. Estimated contract cancellation costs and the allocation of those costs with third parties are subject to further refinement. The ultimate outcome of this matter cannot now be determined.

Cautionary Note Regarding Forward-Looking Statements:

Certain information contained in this release is forward-looking information based on current expectations and plans that involve risks and uncertainties. Forward-looking information includes, among other things, statements concerning cost estimates of termination of the gasifier portion of the IGCC project. Southern Power cautions that there are certain factors that can cause actual results to differ materially from the forward-looking information that has been provided. The reader is cautioned not to put undue reliance on this forward-looking information, which is not a guarantee of future performance and is subject to a number of uncertainties and other factors, many of which are outside the control of Southern Power; accordingly, there can be no assurance that such suggested results will be realized. In addition to the factors discussed in Southern Power’s Annual Report on Form 10-K for the year ended December 31, 2006, and subsequent securities filings, the ultimate determination and allocation of costs related to the project could cause results to differ materially from management expectations as suggested by such forward-looking information. Southern Power expressly disclaims any obligation to update any forward-looking information.
