The story of Entergy Mississippi is the story of modern Mississippi — the people, places and events that sparked a new era of growth and progress for the Magnolia State.
Starting in 1923 with a handful of municipal electric systems, Entergy Mississippi now powers life for more than 461,000 residential, commercial, and industrial customers in 45 counties throughout western Mississippi. Every step of the way, our employees focused on providing safe, reliable, affordable electricity to help our customers thrive and our communities prosper.
Since the earliest days, we have strived to be more than an electricity provider. From our environmental and economic development leadership to our education and poverty-relief programs to our volunteerism and advocacy, we are invested in our communities and are committed to building a better future for all Mississippians.
That was our promise in 1923 as The Mississippi Power and Light Company, and that’s our promise today as Entergy Mississippi. We invite you to explore highlights from our first 100 years through a centennial timeline, stories, photos, videos, and more.
