Utility Landscape

Entergy Mississippi

IOU

Central and northern Mississippi, including Jackson metro area and Delta region

Entergy Mississippi filed a general rate case in 2023 and has been active in pursuing formula rate plan (FRP) adjustments before the MPSC. The company faces ongoing scrutiny over storm cost recovery and infrastructure investment levels.

Mississippi Power Company (Southern Company subsidiary)

IOU

Southern 23 counties of Mississippi, including Gulf Coast and Hattiesburg area

Mississippi Power continues recovery efforts and rate adjustments following the costly Kemper IGCC project debacle, with ongoing depreciation and rate base normalization proceedings. The company has shifted focus toward natural gas and limited solar investment.

Cooperative Energy (formerly Mississippi Valley Gas / SMEPA successor entity)

coop

Wholesale power supply to 11 member distribution cooperatives across Mississippi

Cooperative Energy is navigating generation portfolio transition decisions, including evaluating retirement timelines for legacy coal assets and procurement of replacement capacity amid regional capacity tightness in MISO South.

Four County Electric Power Association

coop

Northeast Mississippi counties including Pontotoc, Union, Lee, and Prentiss

One of the larger G&T cooperatives in the state; pursuing rural broadband deployment through fiber infrastructure investment leveraging USDA ReConnect and ARPA funding streams.

City of Tupelo Electric Department

muni

City of Tupelo and immediate surrounding area in Lee County

Tupelo operates as a TVA-served municipal utility and is largely insulated from MPSC jurisdiction on retail rates; active in smart grid and AMI deployment funded through municipal bonds.

Jackson Utility Division (JXN Water and Sewer, Electric remnant)

muni

City of Jackson and portions of Hinds County

Jackson's municipal utility operations remain under elevated regulatory and federal court oversight following the prolonged water infrastructure crisis; state receivership and federal monitors continue to shape infrastructure investment priorities.

Key Issues

  • Entergy Mississippi formula rate plan (FRP) Rider proceedings: MPSC reviewing annual FRP adjustment filings that include capital additions for grid hardening and distribution automation, with intervenors challenging the pace and prudency of storm-related capital expenditures.

  • Mississippi Power post-Kemper rate normalization and depreciation schedule: Ongoing MPSC proceedings to finalize the amortization of Kemper-related regulatory assets and establish sustainable base rates, with consumer advocates pushing for accelerated ratepayer relief.

  • MISO South capacity adequacy and resource planning: Both Entergy Mississippi and Cooperative Energy face pressure from MPSC staff to demonstrate adequate capacity procurement as MISO tightens reserve margin requirements amid retirement of legacy thermal units.

  • Rural electric cooperative broadband deployment oversight: MPSC and state legislature are monitoring co-op fiber broadband buildouts funded by federal programs, raising questions about cross-subsidization between electric and broadband operations and appropriate regulatory boundaries.

  • Jackson municipal water infrastructure federal receivership and cost allocation: Federal court-appointed receiver managing Jackson's water system is triggering complex questions about ratepayer cost recovery, state funding obligations, and long-term utility governance structure.
