Where Sunnova sits
It serves 51,597 residential customers in California. At 27.55¢ per kilowatt-hour it is one of the cheaper places to buy electricity in California, 17.1% under the statewide average of 33.25¢.
Its customers use very little electricity by national standards, 497 kilowatt-hours a month against 871 nationally. Dense housing, a mild climate or heating that runs on gas rather than electricity all push consumption down, and any of them can leave a household with a modest bill despite a high rate.
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.
