Delaware Rate Case Update
On June 26, 2026 the Delaware Division of the Public Advocate (DPA) filed comments to address developments from the June 24, 2026 rate hearing.
The Delaware PSC meeting regarding On Delmarva’s application for interim rates in the electric base rates case.
DPA urged the DEPSC to deny Delmarva’s proposed interim electric rate increase, arguing that the increase would further strain customers already facing high energy bills. DPA contends that if enacted, SB 326 would immediately limit interim rates to 50% of the proposed increase after seven months and 75% after 12 months.
DPA also argues that, regardless of SB 326’s applicability, Delaware law grants the DEPSC broad authority to modify utility rates when they are unjust.
Finally, according to the DPA, Delmarva’s interim rate request is particularly inappropriate because it is based on a proposed 10.5% return on equity, above the 9.6% authorized in the utility’s last rate case and follows more than a 30% increase in Delmarva’s rate base since 2022.
