Mississippi Power

Profile narrative

Alabama Power and Mississippi Power are investor‑owned electric utilities that generate, transmit, and distribute electricity to residential, commercial, and industrial customers across their respective states. Alabama Power serves the majority of Alabama, while Mississippi Power covers a significant portion of southeast Mississippi, together forming a critical part of the region’s energy infrastructure. Both companies operate as regulated monopolies under the oversight of their state public service commissions, which approve rates and long‑term resource plans. Their generation portfolios include natural gas, coal, nuclear, hydroelectric, and a growing share of solar and battery storage resources. They maintain extensive transmission and distribution networks designed to meet peak demand and ensure reliability across diverse geographic conditions. The utilities also provide energy efficiency programs and support economic development initiatives within their service territories. As regulated entities, their financial performance is tied to approved returns on equity and capital investment recovery mechanisms.

Both companies are wholly owned subsidiaries of Southern Company, one of the largest energy holding companies in the United States, and they operate within Southern Company’s regulated utility segment. Alabama Power, founded in 1906, and Mississippi Power, founded in 1925, have decades of operational history and employ large workforces to manage generation plants, grid assets, and customer services. They are subject to distinct regulatory frameworks: the Alabama Public Service Commission governs Alabama Power, while the Mississippi Public Service Commission oversees Mississippi Power. Notable assets include Alabama Power’s Plant Farley nuclear facility and Mississippi Power’s involvement in advanced generation technologies. In recent years, both utilities have accelerated investments in grid modernization, storm hardening, and renewable integration to meet evolving reliability and environmental expectations. Their combined footprint positions them as essential providers of power for residential life, industrial activity, and critical infrastructure across the Gulf South.
