Key Issues
- —
Delmarva Power grid modernization cost recovery: DPL's pending electric distribution rate case before the PSC involves disputed recovery of Advanced Metering Infrastructure (AMI) deployment and automated switching equipment costs, with intervenors challenging the pace and prudency of capital expenditures exceeding $300 million.
- —
Offshore wind interconnection and transmission cost allocation: Delaware's commitments under its Renewable Portfolio Standard and offshore wind procurement mandates are creating PSC proceedings around how transmission upgrade costs associated with projects in federal waters are allocated to Delaware ratepayers versus the broader PJM footprint.
- —
PFAS contamination cost recovery for Artesian Water: The PSC is evaluating Artesian Water's request to recover costs of PFAS treatment infrastructure through a surcharge mechanism, raising novel questions about liability allocation, insurance offsets, and the appropriate regulatory treatment of environmental remediation as rate base.
- —
Electric vehicle infrastructure and managed charging: The PSC is considering a rulemaking on DPL's proposed EV charging infrastructure program, including make-ready investments, demand charge structures for public charging stations, and time-of-use rate design to manage load impacts on the distribution system.
- —
Low-income energy assistance and weatherization program funding: Heightened legislative and advocacy pressure following federal LIHEAP funding uncertainty has prompted a PSC inquiry into whether utility-administered low-income weatherization and arrearage management programs should be expanded and funded through a dedicated ratepayer surcharge.
Upcoming
Estimated deadline for PSC initial decision or hearing officer report in Artesian Water Company rate case (Docket No. 21-0XXX); parties anticipate recommended decision on PFAS cost recovery surcharge mechanism and authorized return on equity following evidentiary hearings held in early 2026.
Estimated PSC technical conference on Delmarva Power's AMI deployment prudency review; PSC staff and Office of the Public Advocate expected to present findings on whether DPL's AMI vendor selection and rollout timeline meet cost-effectiveness standards under Delaware's grid modernization framework.
Estimated deadline for Delaware PSC to issue a ruling on the proposed EV managed charging and make-ready infrastructure rulemaking docket, following a public comment period that closed in spring 2026; outcome will set rate design precedent for DPL EV programs through at least 2028.
Estimated compliance filing deadline for Delmarva Power under PSC order related to offshore wind transmission cost allocation proceeding; DPL required to submit updated load flow studies and proposed tariff revisions reflecting PJM cost allocation methodology approved in prior order.
