Where Sunnova sits
It is a smaller system, serving 4,578 residential customers, which means its fixed costs are spread across a narrow base. At 18.67¢ per kilowatt-hour it is one of the cheaper places to buy electricity in Maryland, 14.2% under the statewide average of 21.77¢.
Consumption is close to the national norm at 806 kilowatt-hours a month against 871, so the rate translates fairly directly into the bill.
That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.
