SWEPCO electric rates and bills in Louisiana

Three prices for one utility

SWEPCO (Southwestern Electric Power Company) is owned by American Electric Power (AEP) and serves 206,984 Louisiana homes, 9.8%¹ of the state's residential customers. EIA publishes three average prices for them, each covering a different period:

All three are average revenue per kWh: what residential customers were billed in total, divided by the kWh they used. The fixed customer charge, the energy charge, the fuel adjustment and riders are inside that number, most taxes are not, and a small user pays more per kWh than a large one. It is the figure to compare across utilities and years, not a substitute for the rate schedule on file with the Louisiana Public Service Commission, which regulates electric public utilities in the state.

Recent months above the 2025 average

The monthly survey points upward. The 12-month average for September 2025 to August 2026, 14.53¢ per kWh, is above the 2025 average of 13.85¢ per kWh¹, and the August 2026 reading of 14.60¢ per kWh was +8.1%² on August 2025. Across all Louisiana providers, the same month's average rose 2.5%, to 12.87¢ per kWh³. Monthly figures for 2026 are preliminary; EIA's next release, with September 2026 data, is due November 24, 2026.

EIA reports what customers paid, not why it changed. Base-rate cases, fuel adjustment filings and rider updates for SWEPCO's Louisiana customers are all decided at the commission, and the guide to electric rate increases explains how such decisions turn into a monthly bill.

A bill that grew faster than the price

Between 2024 and 2025, SWEPCO's average residential price rose 2.9%, from 13.46¢ per kWh to 13.85¢ per kWh. The average monthly bill changed by +12.1%, from $145.20 to $162.77. The difference is use: the average home went from 1,079 kWh⁴ to 1,175 kWh¹ a month. Statewide, use per home moved much less, from 1,202 kWh⁵ to 1,225 kWh, and the average Louisiana bill rose 8.8%⁶.

The year is lopsided. Over the last 12 months, SWEPCO homes used the least in November 2025, 764 kWh for an average bill of $104.41, and the most in August 2026, 1,830 kWh for $267.15. The highest monthly averages at Cleco ($269.16, August 2026) and Entergy Louisiana ($209.18, August 2026²) were lower.

Households that cannot keep up with a summer bill can apply for the federal Low Income Home Energy Assistance Program, which the Louisiana Housing Corporation runs statewide. Louisiana's LIHEAP allocation for fiscal 2026 was $57.0 million⁷.

The same company costs more in Louisiana

SWEPCO reports to EIA separately for each of its 3 states, and the Louisiana customers paid the most per kWh in 2025: 13.85¢ per kWh, against 12.60¢ per kWh in Texas and 12.14¢ per kWh in Arkansas. Their average bill, $162.77, was also the highest; Texas homes used about as much (1,159 kWh) and paid $146.09, while Arkansas homes used 890 kWh and paid $108.10¹.

The monthly survey shows Arkansas catching up. For the last 12 months (September 2025 to August 2026), SWEPCO's average was 14.53¢ per kWh in Louisiana, 14.51¢ per kWh in Arkansas and 13.43¢ per kWh in Texas; the Arkansas figure for August 2026³ alone was 15.75¢ per kWh, +24.6%² on a year earlier. Across all 12 AEP operating utilities with pages here, SWEPCO's Arkansas business had the lowest 2025 average (12.14¢ per kWh) and AEP Ohio the highest (18.97¢ per kWh¹); the AEP page lists them all, and the Arkansas and Texas SWEPCO pages cover those customers.

Second-highest in Louisiana, below most of the country

Inside Louisiana, SWEPCO's 2025 average was 10.6% above the Louisiana average and the 2nd highest of the 16 utilities with 10,000 or more residential customers; only Cleco Power was higher, at 14.26¢ per kWh. Entergy Louisiana averaged 11.90¢ per kWh and the state's cooperatives together 12.43¢ per kWh¹.

Louisiana's statewide residential average was the 4th lowest⁸ among the states in 2025, so even the top of the state's list sits below the middle of a national one. Among the 177 US utilities with 100,000 or more residential customers, SWEPCO's Louisiana business ranked 59th lowest of 177, below the group's median of 15.07¢ per kWh, and it was 22.1% below the national average for investor-owned utilities¹.

Northwest Louisiana parishes and their other utilities

EIA's 2025 territory records place SWEPCO in 11 parishes: Bienville Parish, Bossier Parish, Caddo Parish, De Soto Parish, Grant Parish, Natchitoches Parish, Red River Parish, Sabine Parish, Vernon Parish, Webster Parish and Winn Parish⁹. In every one of them at least one other utility also reports customers. Entergy Louisiana does in all of them except Caddo and De Soto; Cleco Power in De Soto, Grant, Natchitoches, Red River, Sabine and Vernon; Panola-Harrison Electric Cooperative in Caddo and De Soto; Claiborne Electric Cooperative in Bienville and Webster; and the city systems of Minden, Natchitoches and Winnfield in their own parishes. A parish name is therefore not enough to know who serves a home: SWEPCO's service map decides by address.

All Louisiana homes reported on time-of-use

SWEPCO told EIA that all of its Louisiana residential customers, 206,984 homes or 100.0%, were enrolled in time-of-use pricing in 2025. It reported the same share in Arkansas (100.0%) and Texas (100.0%); at Cleco the share was 1.5%. Advanced meters covered 99.9%¹¹ of SWEPCO's Louisiana residential accounts. EIA's form records enrollment only, so the hours and price differences belong to the rate schedules at the commission, and the time-of-use guide shows how peak hours affect a bill. One consequence for this page: every SWEPCO average above is an average of homes counted as time-of-use customers.

Rooftop solar is less common than in SWEPCO's Arkansas territory: 1,375 net-metered residential installations totalling 7.8 megawatts, or 6.6 per 1,000 customers, against 14.2¹¹ in Arkansas.

Longer outages than the state average

SWEPCO's Louisiana customers averaged 451 minutes without power in 2025 including major events, more than the Louisiana average of 267 minutes, and 332 minutes excluding them, against 216 minutes statewide. They had 3.02 interruptions on average, against 2.20 for Louisiana. Entergy Louisiana, which also reports under IEEE 1366, averaged 253 minutes with major events. SWEPCO's Texas customers had a similar year (467 minutes); its Arkansas customers 428 minutes¹².

Homes buy the largest share

Residential customers bought more of SWEPCO's Louisiana electricity in 2025 than either its commercial or its industrial customers, according to EIA-861. Its 25,866 commercial accounts paid an average of 11.82¢ per kWh, about $871.24 a month, and its 1,915 industrial accounts 9.24¢ per kWh. The average across all 234,765 accounts, 12.25¢ per kWh¹, mixes those classes and says little about a household bill. For every Louisiana utility side by side, see electricity in Louisiana.
