State Intelligence

Updated Jun 1, 2026

Utility Landscape

Duke Energy Carolinas

IOU

Upstate South Carolina, including Greenville, Spartanburg, and surrounding counties

Filed a general rate case in 2024 seeking significant base rate increases tied to capital investments in grid hardening and generation transition; the SC PSC approved a partial settlement with adjustments to requested ROE and capital structure in late 2024.

Duke Energy Progress

IOU

Portions of the Pee Dee region and northeastern South Carolina

Subject to coordinated multi-state oversight with North Carolina regulators; ongoing scrutiny of coal ash remediation cost recovery and IRP compliance under state renewable portfolio directives.

Dominion Energy South Carolina

IOU

Central and coastal South Carolina, including Columbia, Charleston, and the Midlands

Completed a major rate case in 2023 and is pursuing advanced metering infrastructure deployment approval; faces continuing legislative and commission pressure to accelerate solar integration and reduce reliance on natural gas peakers.

Central Electric Power Cooperative

coop

Statewide wholesale power supplier to 20 member distribution cooperatives across South Carolina

Serves as the generation and transmission cooperative for the SC electric cooperative network; managing long-term power supply diversification away from Santee Cooper contracts and evaluating utility-scale solar and storage procurement.

Santee Cooper (South Carolina Public Service Authority)

muni

Berkeley, Georgetown, Horry counties directly; wholesale supplier to Central Electric cooperatives statewide

State-owned utility subject to legislative oversight rather than PSC rate jurisdiction; continuing to navigate post-V.C. Summer financial recovery and a legislative reform framework adopted in 2020 that imposed governance and operational mandates.

City of Newberry Electric Utility

muni

City of Newberry and immediate surrounding service area in Newberry County

Small municipal utility with PSC-exempt rate-setting; monitors Dominion Energy's transmission access terms closely given interconnection dependencies for wholesale power procurement.

Key Issues

  • Dominion Energy South Carolina's AMI deployment docket: The PSC is evaluating a full smart meter rollout proposal with contested cost-benefit analysis; intervenors including SCEUC and ORS are challenging the utility's demand response assumptions and cybersecurity cost allocations.

  • Integrated Resource Planning compliance for Duke Energy Carolinas and Dominion: Both IOUs filed updated IRPs in 2025 reflecting accelerated coal retirements under state and federal pressure; PSC review is ongoing regarding the adequacy of replacement capacity commitments and renewable procurement timelines.

  • Santee Cooper legislative reform and potential divestiture: The SC General Assembly continues to debate Santee Cooper's long-term structure following the failed V.C. Summer nuclear project; a 2025 legislative study committee is examining partial privatization and whether PSC rate jurisdiction should be extended to the authority.

  • Distributed solar and net metering reform: The PSC is revisiting net energy metering successor tariff structures for Dominion and Duke territories following the expiration of the initial RSFI program caps; avoided cost methodology and export compensation rates are actively disputed by solar industry and utility intervenors.

  • Grid resilience and storm hardening cost recovery: Post-hurricane season assessments have prompted Duke Energy Carolinas and Dominion to file for enhanced storm hardening riders; the PSC is scrutinizing whether proposed tracker mechanisms appropriately balance ratepayer protection with utility investment incentives.

Upcoming

Estimated deadline for intervenor testimony in Dominion Energy South Carolina's AMI deployment docket; PSC procedural schedule anticipated to set evidentiary hearing for Q3 2026.

Estimated PSC evidentiary hearing on Duke Energy Carolinas storm hardening rider application; ORS and industrial customer intervenors expected to contest tracker structure and cost cap adequacy.

2026-09-30

Estimated SC PSC order deadline on net metering successor tariff proceeding affecting Dominion and Duke territories; decision will establish export compensation methodology and transition timeline for existing NEM customers.

2026-11-01

Estimated SC General Assembly study committee report due on Santee Cooper governance and PSC jurisdictional expansion options; findings expected to shape 2027 legislative session filings on utility restructuring.
