Pursuant to Rule 457(o) under the Securities Act of 1933, as amended (the "Securities Act"), which permits the registration fee to be calculated on the basis of the maximum offering price of all the securities listed, this Calculation of Filing Fee Table does not specify by each class information as to the amount to be registered, proposed maximum offering price per unit or proposed maximum aggregate offering price. Mississippi Power Company previously filed a Registration Statement on Form S-3 (File No. 333-273697) (the "Prior Registration Statement"), which registered an unallocated aggregate offering price of $1,000,000,000 of Securities, $925,170,000 of which remain unsold (the "Unsold Securities"). Pursuant to Rule 415(a)(6) under the Securities Act, this Registration Statement includes the Unsold Securities. Of the Unsold Securities, (i) $121,535,000 were originally registered on the Prior Registration Statement, with an associated filing fee of $13,393.21, and (ii) $803,634,500 were initially registered on the Registration Statement on Form S-3 (File No. 333-219651) with an associated filing fee of $93,141.24. Mississippi Power Company is continuing to apply the aggregate filing fee of $106,534.45 previously paid in connection with the Unsold Securities to the Unsold Securities. The net filing fee due of $10,334.02 relates to the $74,830,000 aggregate offering price of newly-registered Securities. Pursuant to Rule 415(a)(6), the offering of securities under the Prior Registration Statement will be deemed terminated as of the date of effectiveness of the Registration Statement.
