Wilmington, DE commercial electricity rates
Who delivers electricity to Wilmington businesses, how retail supplier choice works there, the Delaware commercial average with its EIA data month, and who regulates it. Market context with its source and date, never a quote.
EIA averages, data through 06/2026, published per state. All-in means supply and delivery together; supplier contract quotes cover the supply portion only, so the two are not directly comparable.
Wilmington commercial electricity at a glance
Wilmington (New Castle County) is delivered by Delmarva Power, which stays the wires company whichever supplier a business picks. Wilmington is delivered by Delmarva Power, the state's only investor-owned utility, and standard offer service is what a business pays if it never picks a supplier. The EIA publishes a statewide figure, not a city one: the average Delaware commercial account paid 14.40¢ per kWh all-in, supply and delivery together, versus 14.19¢ nationally (EIA, 06/2026), and used about 5,796 kWh a month (EIA, through 2026). That average mixes corner stores with hospitals, so it is market context rather than a quote for any one business, and supplier contract quotes cover the supply portion only, so the two figures are not directly comparable. Voltcheckr LLC is registered as an electricity broker in Texas (PUCT Broker Registration BR260102) and is not currently registered in Delaware.
