Delaware commercial electricity rates
The average all-in rate and monthly usage for the average Delaware commercial account, how retail supplier choice works there, who delivers the power and who regulates it. Market context with its source and date, never a quote.
EIA averages, data through 06/2026. All-in means supply and delivery together; supplier contract quotes cover the supply portion only, so the two are not directly comparable.
Delaware commercial electricity at a glance
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. Among the 14 states with retail electricity choice, Delaware has the 4th lowest all-in commercial average. The regulator is the Delaware Public Service Commission. Voltcheckr LLC is registered as an electricity broker in Texas (PUCT Broker Registration BR260102) and is not currently registered in Delaware.
How retail electricity choice works in Delaware
Delaware's retail electric choice covers Delmarva Power's service territory, which includes Wilmington and most of New Castle County. Delmarva keeps delivering and billing, and a business can buy its supply from a competitive supplier certified by the Delaware PSC or stay on Delmarva's standard offer service. Members of Delaware Electric Cooperative and customers of municipal utilities such as Dover, Newark and Milford do not have supplier choice.
