ENTERGY MISSISSIPPI, LLC Business Summary

Entergy Mississippi, LLC (EMP) operates as a regulated electric utility, generating revenue primarily through the production, transmission, and retail distribution of electricity to approximately 459,000 customers across 45 counties in western and central Mississippi. The company’s revenue model is centered on rate-regulated electricity sales categorized into residential, commercial, industrial, and governmental segments, supplemented by wholesale sales for resale. As a subsidiary of Entergy Corporation, EMP is currently executing its "Superpower Mississippi" initiative, a multi-billion-dollar grid modernization and generation expansion strategy—including the 754-megawatt Vicksburg Advanced Power Station—to support massive industrial loads from partners like Amazon Web Services. EMP’s primary regional competitors include Southern Company (Mississippi Power), the Tennessee Valley Authority (TVA), and Cooperative Energy; within this landscape, EMP maintains a dominant market position as the state’s largest investor-owned utility, distinguished by its extensive nuclear-integrated generation portfolio and aggressive economic development integration. Leadership is spearheaded by President and CEO Haley Fisackerly, a veteran executive who has led the utility since 2008 and previously held senior roles in regulatory affairs and customer operations following his tenure in the U.S. Senate. The executive team was recently bolstered in 2025 with the appointments of Lee Alexander as Vice President of Power Plant Operations, an operations expert with over 25 years at Entergy, and Kamisha Quates as Vice President of Reliability, who oversees grid engineering and emergency restoration. Jeremy Vanderloo, a U.S. Naval Academy graduate and former U.S. Marine Corps major, serves as Vice President of Business Operations and Strategy, directing the company’s long-term regulatory and growth initiatives. While EMP is a wholly-owned subsidiary of the New York Stock Exchange-listed Entergy Corporation (ETR), its strategic direction is governed by a localized leadership team with deep pedigrees in utility management, public policy, and large-scale infrastructure deployment.
