Where Black River Electric Coop, Inc sits

It is a smaller system, serving 30,610 residential customers, which means its fixed costs are spread across a narrow base. At 13.47¢ per kilowatt-hour it is one of the cheaper places to buy electricity in South Carolina, 16.7% under the statewide average of 16.18¢.

Consumption here is high, 1,258 kilowatt-hours a month against a national average of 871. Long cooling seasons, large detached homes and electric resistance heating are the usual causes, and together they matter more to the bill than the rate does.

Owned by the customers it serves, with directors elected by members. Co-ops are frequently outside state rate regulation. 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.
