On February 14, 2025, Mississippi Power submitted its annual ECO Plan filing to the Mississippi PSC, which requested a $6 million annual increase in revenues.

On May 28, 2024, the FERC issued an order accepting Mississippi Power's request for an $8 million increase in annual wholesale base revenues under the MRA tariff, effective May 29, 2024, subject to refund. On December 23, 2024, Mississippi Power and Cooperative Energy filed a settlement agreement with the FERC. The settlement agreement provides for (i) a $1 million increase in annual wholesale base revenues and a refund to customers of approximately $4 million, (ii) a rate escalation of 2.5% on an annual basis in periods subsequent to December 31, 2024 and continuing through the end of the Shared Services Agreement (SSA) on December 31, 2035, and (iii) a waiver of rights by Mississippi Power and Cooperative Energy to file for any changes in non-fuel rates through the end of the term of the SSA. The settlement agreement is subject to approval by the FERC.

The ultimate outcome of these matters cannot be determined at this time. See Note 2 to the financial statements under "Mississippi Power" for additional information.

Southern Power

During 2024, Southern Power completed construction of and placed in service the 150-MW South Cheyenne solar facility. In addition, Southern Power continued construction of the 200-MW first phase and began construction of the 180-MW second phase and the 132-MW third phase of the Millers Branch solar facility with commercial operation projected to occur in the fourth quarter 2025, the second quarter 2026, and the fourth quarter 2026, respectively. Upon completion, the Millers Branch solar project will have a total generating capacity of 512 MWs, substantially all of which is contracted under multiple PPAs ranging from 15 years to 20 years.

In November 2024, Southern Power committed to a development project to repower 200 MWs of the 299-MW Kay Wind facility. The output of the project is contracted under an amended 20-year PPA with commercial operation projected to occur in the third quarter 2026.
