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
