Company overview

MISSISSIPPI POWER CO

Mississippi Power Co. remains a regional electric utility primarily delivering generation, transmission and distribution services across southern Mississippi, serving residential neighborhoods, commercial hubs and industrial plants that depend on reliable, year-round energy as well as tailored demand-side management solutions. As a subsidiary of a larger holding company, its core operations—power plant dispatch, grid maintenance and customer energy efficiency programs—are shaped by the SIC-defined electric light and power industry, which demands careful balancing of capital investments in infrastructure with rate decisions overseen by state regulators. The company’s obligations to regional regulators and federal agencies introduce material risks related to environmental compliance, storm resilience, fuel supply volatility and the ability to justify major grid modernizations amid evolving customer expectations.
