Entergy Mississippi

What Entergy Mississippi does

Entergy Mississippi is a regulated, vertically integrated electric utility headquartered in Jackson, Mississippi, founded in 1923 and operating as a wholly-owned subsidiary of Entergy Corporation (NYSE: ETR). It serves residential, commercial, and large industrial customers across the state under an exclusive service territory granted by the Mississippi Public Service Commission, generating revenue through administratively approved rates designed to recover operating costs and a regulated return on capital investment.

The company's core operations span electricity generation, transmission, and distribution, supported by a portfolio of customer-facing digital products including the myEntergy portal, mobile applications (iOS/Android), a real-time outage map, a Storm Center for severe-weather preparedness, and bill-management tooling. Generation and grid assets include legacy natural gas facilities (now being retired) and modern combined-cycle assets; a flagship 754-megawatt combined-cycle natural gas facility — the Vicksburg Advanced Power Station — is under construction at a cost of $1.2 billion as the cornerstone of the "Superpower Mississippi" capacity-expansion plan.

The business model is a regulated subscription: revenue is earned through cost-of-service ratemaking, with capital projects recovered through rate base growth. Customer segments are horizontally defined across residential, commercial/business, and large industrial accounts. The commercial and industrial pipeline has accelerated materially through a strategic partnership with Amazon, in which Amazon funds the energy infrastructure costs for hyperscale data center campuses in Mississippi (totaling $25 billion planned investment, including $11 billion in Madison County and $1 billion at the former Delphi site in Hinds County), enabling a $300 million grid modernization initiative that improves reliability for all ratepayers.

Regional players

• Alabama Power: Southern Company subsidiary and regulated electric utility serving Alabama, neighboring Mississippi. Comparable in generation portfolio, regulatory framework, and customer segments including large industrial users.
• Tennessee Valley Authority: Federal utility serving parts of northern Mississippi and surrounding states. Comparable in regulated electric generation, transmission, and economic development role, but operates under a different governance and geographic model.
• Georgia Power: Southern Company's largest operating company and a regulated electric utility in the Southeast. Similar in scale, regulated rate base growth, and reliance on industrial customers for load growth.

Direct peers

• Mississippi Power: Southern Company subsidiary operating as a regulated electric utility within Mississippi. Same regulatory jurisdiction (MPSC) and same end-customer base, making it the closest direct peer for retail and industrial load competition.
• Entergy Arkansas: Another Entergy Corporation operating company providing regulated electric service. Shares corporate parent, generation strategy, customer programs (myEntergy), and rate-regulated business model.
• Entergy Louisiana: Sister Entergy Corporation operating company that is itself a regulated electric utility in an adjacent Gulf state. Highly comparable in generation mix, regulatory structure, and reliance on large industrial customers.

Broad incumbents

• Duke Energy: Large US regulated electric utility holding company operating across the Carolinas, Florida, Midwest, and other regions. Comparable vertically integrated utility model, but operates at much larger scale and in different jurisdictions.
• NextEra Energy: Largest US electric utility by market cap with regulated FPL operations and a leading renewables platform. Comparable as a regulated electric utility benchmark, but with a fundamentally different generation mix and growth profile.
• Southern Company: Parent of Mississippi Power, Alabama Power, and Georgia Power. Operates the same regulated utility model across the Southeast and is a broad incumbent benchmark for regulated returns and capital deployment.
• Dominion Energy: Large regulated US electric utility with operations across Virginia, the Carolinas, and other states. Comparable regulated utility model and exposure to large-load customer growth, though in different geographies.
