Where Navajo Tribal Utility Authority sits
It is a smaller system, serving 27,014 residential customers, which means its fixed costs are spread across a narrow base. Its 16.63¢ per kilowatt-hour runs 9.2% above the Arizona average of 15.23¢.
Its customers use very little electricity by national standards, 490 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.
Operated by the state itself, with rates set through a public body rather than a commission proceeding. 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.
