Key Issues
- —
Delmarva Power grid modernization and Advanced Metering Infrastructure (AMI) deployment: PSC staff and consumer advocates are scrutinizing the cost-benefit methodology and data privacy protections associated with DPL's proposed AMI rollout, with disputes over rate design and opt-out provisions remaining unresolved as of mid-2025.
- —
PFAS contamination cost recovery in water utility rate cases: Artesian Water's pending rate case has elevated the broader question of how Delaware ratepayers should bear costs of per- and polyfluoroalkyl substance treatment upgrades mandated by EPA's April 2024 PFAS National Primary Drinking Water Rule, with the PSC considering guidelines applicable across all regulated water utilities.
- —
Renewable Portfolio Standard compliance and offshore wind procurement: Following the cancellation of several Atlantic offshore wind contracts nationally, Delaware's RPS compliance trajectory and Delmarva Power's renewable procurement obligations under the Delaware Energy Act are under active legislative and commission scrutiny heading into 2026 compliance reporting cycles.
- —
Electric vehicle infrastructure and utility role: The PSC is considering a docket examining the appropriate role of regulated utilities in deploying EV charging infrastructure, including whether DPL and DEC should be permitted to invest ratepayer capital in charging assets and under what conditions, amid tension between utility proposals and competitive market advocates.
- —
Natural gas expansion versus decarbonization policy tension: Chesapeake Utilities' pipeline expansion requests in Sussex County face growing opposition from environmental intervenors citing Delaware's climate commitments under the Governor's Executive Order 6, creating a contested policy record before the PSC on whether new gas infrastructure investments should receive traditional ratemaking treatment.
