Where Sunnova sits
It is a smaller system, serving 16,865 residential customers, which means its fixed costs are spread across a narrow base. At 23.80¢ per kilowatt-hour it is one of the cheaper places to buy electricity in Massachusetts, 17.4% under the statewide average of 28.82¢.
Consumption here is below the national norm at 640 kilowatt-hours a month against 871, which softens the effect of the rate on the final 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.
