Utility landscape

• Louisville Gas and Electric Company (LG&E) IOU

  Louisville metro area and surrounding counties in north-central Kentucky

  LG&E, a PPL subsidiary, filed a combined rate case with KU in 2023 seeking significant base rate increases tied to grid modernization and generation transition costs. The KPSC approved a settlement in 2024 with revenue increases below the requested amounts, subject to ongoing compliance filings.

• Kentucky Utilities Company (KU) IOU

  Central and eastern Kentucky, serving approximately 550,000 customers across 77 counties

  As a co-filer with LG&E in recent rate proceedings, KU faces regulatory scrutiny over its coal-to-gas transition strategy and integrated resource plan compliance. The KPSC has required enhanced reporting on coal plant retirement timelines and replacement capacity procurement.

• Duke Energy Kentucky IOU

  Northern Kentucky counties bordering the Cincinnati metro area

  Duke Energy Kentucky filed a base rate case in 2024 seeking recovery of investments in grid hardening and natural gas infrastructure upgrades. The commission has focused on cost allocation between Kentucky and Ohio jurisdictions given Duke's multi-state integrated system.

• Big Sandy Rural Electric Cooperative Corporation coop

  Eastern Kentucky coalfield counties including Lawrence, Johnson, Martin, and Pike counties

  Big Sandy REC operates in economically distressed eastern Kentucky and has pursued federal broadband funding under USDA ReConnect to bundle electric and broadband service. Rate stability and reliability investment in aging rural infrastructure remain primary concerns before the KPSC.

• Jackson Purchase Energy Corporation coop

  Eight westernmost counties of Kentucky including McCracken, Calloway, and Marshall counties

  Jackson Purchase Energy has engaged with the KPSC on demand-side management program approvals and solar integration tariffs as member interest in distributed generation grows. The cooperative's power supply relationship with TVA shapes its resource planning flexibility.

• Paducah Power System muni

  City of Paducah and portions of McCracken County in western Kentucky

  Paducah Power System, as a TVA distributor, has limited direct KPSC rate jurisdiction but engages with state regulators on service territory boundary and interconnection matters. Municipally owned infrastructure aging and capital funding strategies are ongoing governance concerns.

Key issues

• LG&E and KU integrated resource plan (IRP) compliance and coal plant retirement sequencing: The KPSC is actively monitoring both utilities' plans to retire aging coal generation while ensuring resource adequacy, with scrutiny on the pace of replacement capacity procurement amid MISO capacity market tightness.
• Grid modernization cost recovery and advanced metering infrastructure (AMI) deployment: LG&E and KU are seeking tracker mechanisms to recover AMI and distribution automation investments outside of traditional rate cases, raising commission debate over rate design and customer rate impact timing.
• Duke Energy Kentucky's multi-jurisdictional cost allocation: The KPSC is engaged in proceedings examining how Duke allocates shared transmission and generation costs between its Kentucky and Ohio service territories, with intervenors challenging methodologies that may disadvantage Kentucky ratepayers.
• Rural broadband buildout over electric utility infrastructure: Multiple Kentucky electric cooperatives are pursuing pole attachment agreements, rights-of-way, and KPSC coordination related to federal BEAD and USDA broadband funding programs, requiring commission guidance on utility involvement in broadband service provision.
• Renewable energy tariff and distributed generation net metering reform: The KPSC is considering updates to net metering rules and large commercial renewable tariff structures for LG&E and KU customers following legislative direction in recent Kentucky General Assembly sessions, with stakeholder proceedings ongoing.
