Where Southwestern Electric Power Co sits

It serves 207,011 residential customers in Louisiana. Its 13.46¢ per kilowatt-hour sits 4.9% below the Louisiana average of 14.15¢.

Its customers use more electricity than the national norm, 1,079 kilowatt-hours a month against 871, which amplifies whatever the rate does.

A shareholder-owned company whose rates are set by the state regulator, including an approved return on the capital it has invested. 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.

How often the power goes out

In 2024 the average Southwestern Electric Power Co customer went 984 minutes without electricity across 2.79 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.

Average outage length 353 minutes per interruption

Optional rate plans

Southwestern Electric Power Co offers time-of-use pricing to residential customers. 206,897 households were enrolled, about 99.9% of its residential base.

These plans are opt-in almost everywhere. They reward households that can move laundry, dishwashing, water heating or electric vehicle charging out of the late-afternoon peak, and they cost more than the standard rate for households that cannot. How to tell which group you are in.

Rooftop solar on this system

1,378 residential customers had net-metered solar in 2024, totalling 7.83 megawatts. That works out to 6.7 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.
