Which utility serves Louisiana, and what does it charge?
The 8 largest utilities selling to Louisiana homes, by residential customers, with the price full-service customers paid and how many run net-metered solar.
| Utility | Type | Homes served | Price per kWh | Use per home, monthly | Net-metered systems |
|---|---|---|---|---|---|
| Entergy Louisiana LLC | Investor-owned | 957,522 (44.6%) | 11.05¢ | 1,224 kWh | 14,464 (1.5%) |
| Cleco Power LLC | Investor-owned | 251,927 (11.7%) | 12.33¢ | 1,217 kWh | 4,158 (1.7%) |

Each Louisiana price is residential revenue divided by sales for full-service customers (HyreSolar calculation); a wires company’s price is its default-service price.
What do the Louisiana utility figures mean for a solar quote?
EIA-861 lists 20 utilities serving homes in Louisiana in 2024, across 2,147,640 residential accounts. The three largest, Entergy Louisiana LLC, Cleco Power LLC and Southwestern Electric Power Company, served 66.0% of those homes. By ownership: investor-owned utilities 74.7%, electric cooperatives 18.5%, municipal utilities 5.0% and small utilities EIA counts as a group 1.7%.
All 2,147,640 Louisiana residential accounts bought energy from the utility that delivers it; EIA counted none on a competitive supplier. So a Louisiana utility’s own tariff sets both the price you avoid and the credit for what you export.
Entergy Louisiana LLC, the largest, served 957,522 Louisiana homes (44.6%). Its full-service residential customers paid 11.05¢ per kWh, below the Louisiana average of 11.73¢, and used 1,224 kWh a month on average. 14,464 of its customers ran net-metered rooftop solar, 1.5% of its homes against 1.60% statewide.
Among the 20 Louisiana utilities with at least 5,000 residential customers and a full-service price, the price ran from 5.66¢ at City of Ruston to 14.05¢ at Jefferson Davis Electric Co-op. At the Louisiana average of 14,422 kWh a year, that 8.39¢ gap is worth about $1,210 a year (our arithmetic), so the same system offsets more money in one territory than the other.
Price a quote on your own utility’s rate, not the 11.73¢ Louisiana average.
Rooftop solar is concentrated: Entergy Louisiana LLC alone accounts for 14,464 net-metered residential systems, about 42% of the 34,417 counted in Louisiana, and 19 Louisiana utilities reported any at all. The highest adoption among the larger utilities was at Entergy New Orleans, LLC, where 5.2% of homes had a system.
What does power cost in Louisiana, and why does it matter?
Residential electricity in Louisiana averaged 11.73¢ per kilowatt-hour in 2024, the 4th-lowest of 51 and below the national 16.48¢. That is one of the lowest residential prices in the country. Each avoided kilowatt-hour is worth little, which can stretch payback in Louisiana whatever the sunshine.
The average Louisiana household bill was $140.96 a month ($1,692 a year), the 22nd-highest of 51, against $142.26 nationally. That $1,692 is the ceiling on what solar could save a typical Louisiana home, before fixed monthly charges.
Only 9.8% of Louisiana homes were on a time-varying rate in 2024 (11.1% nationally), so a flat rate is the likely starting point. 89.0% of Louisiana residential meters were smart meters (83.8% nationally), and a time-varying rate needs one. How time-of-use changes solar.
How many Louisiana homes have solar?
Louisiana had 34,417 rooftop systems on net metering in 2024, across 2,147,745 residential accounts: 1.60% of homes, the 26th-highest of 51. Adoption in Louisiana sits in the middle of the 51: neither an early market nor a late one.
The Louisiana market counted 2,957 more systems in 2024 than in 2023 and has grown 5.1% a year over five years, the 3rd-lowest of 51. Where growth has turned nationally.
How has Louisiana solar changed since 2014?
Louisiana counted 15,571 net-metered rooftop systems in 2014 and 34,417 in 2024, 2.2 times as many. The share of homes with one moved from 0.77% to 1.60%. The biggest one-year addition came in 2015, with 4,655 more systems than the year before.
| Year | Rooftop systems | Share of homes | Average size | Residential price |
|---|---|---|---|---|
| 2014 | 15,571 | 0.77% | 5.5 kW | 9.57¢ |
| 2016 | 22,576 | 1.10% | 5.8 kW | 9.34¢ |
| 2018 | 25,449 | 1.22% | 5.0 kW | 9.59¢ |
| 2020 | 27,661 | 1.31% | 5.0 kW | 9.67¢ |
| 2022 | 28,690 | 1.35% | 5.2 kW | 12.93¢ |
| 2024 | 34,417 | 1.60% | 5.5 kW | 11.73¢ |

What does the Louisiana trend mean for a savings estimate?
Over the same years the Louisiana residential price went from 9.57¢ to 11.73¢ per kWh, up 23%, and the average system from 5.5 kW to 5.5 kW. With Louisiana prices up 23% across ten years, a savings estimate that assumes steep yearly rate rises is assuming more than this record shows.
How big is a typical Louisiana system?
The average Louisiana system was 5.46 kW in 2024, the 5th-lowest of 51, against 6.74 kW nationally. Louisiana homes used 14,422 kilowatt-hours a year each, the highest of 51.
A Louisiana home using 14,422 kWh is an average, not a design input: size from your own twelve months of bills and usable roof with cost by system size and the system size calculator.
Who owns the systems in Louisiana?
In Louisiana, 0.3% of systems were third-party owned in 2024: leased, or on a power purchase agreement (PPA), rather than owned by the household. That is the 10th-lowest of 38, against 29.1% nationally.
Nearly every Louisiana system is owned by the household. A lease or power purchase agreement would be unusual here, which is a reason to read one closely. Whoever owns a Louisiana system claims any tax credit on it: Section 48E explained.
Do Louisiana homes add batteries?
In Louisiana, 0.01% of solar systems were paired with a battery in 2024 (2 systems), the 3rd-lowest of 47. Louisiana’s share is well under half the national 5.86%.
On reliability, the average Louisiana customer went 631 minutes without power in 2024 counting major storms, and 216 minutes without them. The median state saw 297. Outages in every state.
Whether a battery pays in Louisiana turns on your utility’s export credit and your own outage history: what a home battery does.
How do you check a solar company’s license in Louisiana?
We checked 48 Louisiana solar companies from June to August 2026 against the state license register. None of those showed an expired or revoked license when checked.
The license classes we found on Louisiana solar work are S.12 Solar Energy Equipment. Ask which one a company holds, then confirm the number with the issuing authority yourself.
These counts describe the companies we checked on those dates, not every company in Louisiana, and a license current then may have lapsed since. How to verify a solar license.

Where do the Louisiana numbers come from?
The Louisiana figures are HyreSolar calculations from the Form EIA-861 annual files: 34,417 net-metered residential systems counted against 2,147,745 residential accounts, sizes as means, and 20 utility-level rows for the utility table, matched to net-metering records by EIA utility number.
The method and limits cover all 51; the Louisiana row is in the data as a CSV.
No Louisiana figure here is an estimate for one home: your roof, usage, utility tariff and tax position decide that.

Primary-source research, data analysis and fact checking
We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is why the rest can be checked.

How this desk works
- Primary sources only. Statutes from the legislature’s own publishing system, federal data from the agency that collects it, code text from the adopted edition, manufacturer claims from the data sheet. We do not cite an article that cites a source; we go and read the source.
- Every figure carries its provenance. A named document and the date we retrieved it, so you can check it and so you know how old it is. Retrieval dates are not decoration: an EIA rate from May is a different fact from an EIA rate from August.
- We publish what we could not verify. Every research page carries a section naming the things we tried to establish and could not, and why. A paywalled standard, a state website that refused the request, a manufacturer that publishes no figure at all.
- We separate measurement from modeling from our own reasoning, and label which is which on the page. A laboratory measurement, an assumption inside a modeling tool and our own inference are three different kinds of claim and they are never presented as one.
- We do not sell solar, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Data as of EIA-861 2024 final release. Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
