Rockville, MD commercial electricity rates
Who delivers electricity to Rockville businesses, how retail supplier choice works there, the Maryland 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.
Rockville commercial electricity at a glance
Rockville (Montgomery County) is delivered by Pepco, which stays the wires company whichever supplier a business picks. Rockville is delivered by Pepco along the I-270 corridor. The EIA publishes a statewide figure, not a city one: the average Maryland commercial account paid 16.84¢ per kWh all-in, supply and delivery together, versus 14.19¢ nationally (EIA, 06/2026), and used about 8,741 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.
