Mississippi Power Co. filed a shelf registration statement for the potential sale of up to $2 billion worth of securities.

The Aug. 3 filing covers the sale of an unspecified amount of the Southern Co. subsidiary's preferred stock, depositary preferred shares, senior notes and junior subordinated notes. Each depositary preferred share represents one-fourth of a share of preferred stock.

The company plans to use proceeds from any sale of the securities to fund its ongoing construction program, to pay scheduled maturities and/or refundings of its securities, to repay outstanding short-term debt and for other general corporate purposes.
