Item 8.01. Other Events.

See MANAGEMENT’S DISCUSSION AND ANALYSIS — FINANCIAL CONDITION AND LIQUIDITY — “Capital Requirements and Contractual Obligations” of Mississippi Power Company (the “Company”) in Item 7 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2007 (the “Form 10-K”) for a description of the Company’s capital requirements for its construction program. In October 2008, the Company’s Board of Directors approved a new capital budget for 2009 and 2010. The Company’s current estimate of construction costs for 2009 is approximately $280,000,000 and for 2010 is approximately $447,000,000.  The current estimates of construction costs for 2009 and 2010 are specifically subject to the Company filing a request for a certificate of public convenience and necessity with the Mississippi Public Service Commission (the “Mississippi PSC”) for authority to construct, own, and operate the integrated coal gasification combined cycle project in Kemper County, Mississippi (the “Project”), and the subsequent approval of that request by the Mississippi PSC. See MANAGEMENT’S DISCUSSION AND ANALYSIS — FUTURE EARNINGS POTENTIAL — “Construction Projects” in Item 7 of the Form 10-K and MANAGEMENT’S DISCUSSION AND ANALYSIS — FUTURE EARNINGS POTENTIAL — “Integrated Coal Gasification Combined Cycle” in the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2008 (the “Form 10-Q”) for additional information regarding the Project. The Company’s estimated construction costs are forward-looking statements and actual construction costs may vary materially from these estimates because of changes in such factors as: business conditions; environmental statutes and regulations; Federal Energy Regulatory Commission rules and regulations; load projections; storm impacts; the cost

and efficiency of construction labor, equipment, and materials; the cost and availability of capital; and other risk factors described in the Form 10-K and the Form 10-Q. In addition, there can be no assurance that costs related to capital expenditures will be fully recovered.  The Southern Company system financial plan, including its capital budget, is expected to be reviewed by The Southern Company’s Board of Directors in early 2009.
