Mid-Carolina Electric Coop Inc electricity rates

It serves 56,463 residential customers in South Carolina. Its 14.88¢ per kilowatt-hour sits 8% below the South Carolina average of 16.18¢.

Its customers use more electricity than the national norm, 1,146 kilowatt-hours a month against 871, which amplifies whatever 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.

In 2024 the average Mid-Carolina Electric Coop Inc customer went 3,915 minutes without electricity across 3.22 interruptions. The median across the 941 utilities that report this is 185 minutes.

That is far worse than typical, and figures at this level almost always reflect a major storm season rather than everyday performance. A single hurricane or ice storm can dominate the annual number.

186 residential customers had net-metered solar in 2024, totalling 1.27 megawatts. That works out to 3.3 installations per thousand customers, against a median of 8 across the utilities reporting it.

Adoption is below the national median. A low retail rate reduces what solar displaces, and export compensation set at avoided cost rather than the retail rate reduces it further. What exports are actually worth.
