History of Mississippi Power

Founded: 1910
Founders: Mississippi Power Company
Acquired by Southern Company: 1945

Mississippi Power Company was founded in 1910 and grew to become a major electric utility serving the Mississippi Gulf Coast region. The company provided electricity to residential, commercial, and industrial customers in southern Mississippi.

Mississippi Power became part of Southern Company in 1945 when Southern Company was formed as a holding company for utility operations in the Southeast. Under Southern Company's ownership, Mississippi Power expanded its operations, investing in generation capacity and distribution infrastructure.

In the 2010s, Mississippi Power was involved in the Kemper County integrated coal gasification combined cycle (IGCC) project, a controversial clean coal plant that faced significant cost overruns and technical challenges. The project was abandoned in 2017, and the gasifier-related assets were slated for dismantlement. Dismantlement of the abandoned gasifier-related assets was completed at the end of 2025, and site restoration activities are substantially complete. Any additional costs are expected to be immaterial.

In recent years, Mississippi Power has invested in modernizing its generation portfolio and distribution infrastructure. The company has focused on grid modernization, smart grid technology, renewable energy integration, and improving service reliability. Mississippi Power supports distributed generation systems through renewable energy programs that allow customers to generate their own electricity and export excess power back to the grid.
