Our history
It all started with sawdust
It all started with a handshake, some sawdust … and a vision. Over a century ago, Harvey Couch had the idea to bring safe, affordable, reliable power to the Middle South — power that would open the door to the modern world for the people and communities we serve. In 1923, he chartered The Mississippi Power & Light Company, which later became Entergy Mississippi. His vision lives on today: Entergy Mississippi delivers electricity to more than 460,000 utility customers across the state.
