Utility landscape

• Delmarva Power & Light Company (DPL) IOU

  Northern and central Delaware for electric; limited natural gas service in New Castle County

  Subsidiary of Exelon's Pepco Holdings; subject to ongoing infrastructure investment and cost-recovery proceedings before the PSC. Most recently filed for electric distribution rate adjustments tied to grid modernization capital expenditures.

• Chesapeake Utilities Corporation IOU

  Natural gas distribution across much of Delaware, including Kent and Sussex Counties

  Actively pursuing pipeline expansion and system reliability investments; has sought rate base increases to recover costs associated with main replacement programs and system extension to underserved areas.

• Delaware Electric Cooperative (DEC) coop

  Rural portions of Kent and Sussex Counties in southern Delaware

  As a member-owned cooperative, DEC is subject to PSC jurisdiction for certain matters; has been investing in grid hardening and distributed energy resources to serve its predominantly rural membership base.

• City of Dover Electric muni

  City of Dover and portions of surrounding Kent County

  Municipally owned utility operating under its own rate-setting authority; participates in PJM capacity markets and has been evaluating solar procurement options to meet sustainability goals without direct PSC rate oversight.

• Artesian Water Company IOU

  Water service across New Castle County and portions of Kent and Sussex Counties

  Subsidiary of Artesian Resources Corporation; has pursued multiple rate cases in recent years to recover infrastructure replacement costs and address PFAS remediation capital expenditures, drawing significant PSC scrutiny on return on equity levels.

Key issues

• Delmarva Power grid modernization cost recovery: PSC evaluating DPL's proposed distribution system modernization plan (DSMP) and associated deferred cost recovery mechanisms, with intervenors challenging the pace and prudency of smart meter and automation investments.
• PFAS remediation cost allocation for Artesian Water: Ongoing proceedings to determine the extent to which costs associated with PFAS/PFOA contamination response and treatment infrastructure may be passed through to ratepayers versus absorbed by shareholders.
• Renewable energy portfolio standard (RPS) compliance and offshore wind integration: Delaware's RPS requires increasing renewable procurement, and the PSC is actively engaged in proceedings related to interconnection costs and cost allocation for offshore wind projects in the PJM queue affecting Delmarva's distribution system.
• Low-income customer assistance program (LICAP) funding adequacy: PSC and stakeholders reviewing sufficiency of existing low-income energy assistance mechanisms administered through DPL and Chesapeake Utilities amid post-pandemic arrears and elevated energy burdens.
• Chesapeake Utilities natural gas system expansion prudency review: PSC scrutinizing whether proposed extensions into new service territories are consistent with Delaware's decarbonization policy trajectory, creating tension between utility growth plans and state climate commitments.
