Which utility serves Mississippi, and what does it charge?
The 8 largest utilities selling to Mississippi 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 Mississippi LLC | Investor-owned | 384,611 (28.7%) | 13.21¢ | 1,188 kWh | 625 (0.16%) |
| Mississippi Power Company | Investor-owned | 157,437 (11.8%) | 14.47¢ | 1,110 kWh | 496 (0.32%) |

Each Mississippi 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 Mississippi utility figures mean for a solar quote?
EIA-861 lists 40 utilities serving homes in Mississippi in 2024, across 1,340,459 residential accounts. The three largest, Entergy Mississippi LLC, Mississippi Power Company and Coast Electric Power Association, served 46.6% of those homes. By ownership: electric cooperatives 50.5%, investor-owned utilities 40.4%, municipal utilities 6.4% and small utilities EIA counts as a group 2.7%.
All 1,340,459 Mississippi residential accounts bought energy from the utility that delivers it; EIA counted none on a competitive supplier. So a Mississippi utility’s own tariff sets both the price you avoid and the credit for what you export.
Entergy Mississippi LLC, the largest, served 384,611 Mississippi homes (28.7%). Its full-service residential customers paid 13.21¢ per kWh, below the Mississippi average of 13.39¢, and used 1,188 kWh a month on average. 625 of its customers ran net-metered rooftop solar, 0.16% of its homes against 0.13% statewide.
Among the 32 Mississippi utilities with at least 5,000 residential customers and a full-service price, the price ran from 10.86¢ at Prentiss County Electric Power Association to 16.33¢ at Yazoo Valley Electric Power Association.
At the Mississippi average of 13,871 kWh a year, that 5.47¢ gap is worth about $759 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 13.39¢ Mississippi average.
Rooftop solar is concentrated: Entergy Mississippi LLC alone accounts for 625 net-metered residential systems, about 35% of the 1,789 counted in Mississippi, and 8 Mississippi utilities reported any at all. The highest adoption among the larger utilities was at Coast Electric Power Association, where 0.47% of homes had a system.
What does power cost in Mississippi, and why does it matter?
Residential electricity in Mississippi averaged 13.39¢ per kilowatt-hour in 2024, the 15th-lowest of 51 and below the national 16.48¢. Retail power in Mississippi is cheaper than in 36 of the other 50 jurisdictions. Each kilowatt-hour a system avoids is worth less, which lengthens payback.
The average Mississippi household bill was $154.83 a month ($1,858 a year), the 11th-highest of 51, against $142.26 nationally. That $1,858 is the ceiling on what solar could save a typical Mississippi home, before fixed monthly charges.
Only 2.1% of Mississippi homes were on a time-varying rate in 2024 (11.1% nationally), so a flat rate is the likely starting point. 79.9% of Mississippi residential meters were smart meters (83.8% nationally), and a time-varying rate needs one. How time-of-use changes solar.
How many Mississippi homes have solar?
Mississippi had 1,789 rooftop systems on net metering in 2024, across 1,340,459 residential accounts: 0.13% of homes, the 5th-lowest of 51. Mississippi is one of the least developed rooftop markets in the country. Expect few local installers and a permit office with little solar experience, and allow time for both.
The Mississippi market counted 608 more systems in 2024 than in 2023 and has grown 28.3% a year over five years, the 20th-highest of 51. Where growth has turned nationally.
How has Mississippi solar changed since 2014?
Mississippi counted 21 net-metered rooftop systems in 2014 and 1,789 in 2024, 85.2 times as many. The share of homes with one moved from under 0.01% to 0.13%. The biggest one-year addition came in 2024, with 608 more systems than the year before.
| Year | Rooftop systems | Share of homes | Average size | Residential price |
|---|---|---|---|---|
| 2014 | 21 | under 0.01% | 26.3 kW | 11.32¢ |
| 2016 | 154 | 0.01% | 5.4 kW | 10.47¢ |
| 2018 | 389 | 0.03% | 6.4 kW | 11.12¢ |
| 2020 | 594 | 0.05% | 4.9 kW | 11.17¢ |
| 2022 | 946 | 0.07% | 5.6 kW | 12.41¢ |
| 2024 | 1,789 | 0.13% | 5.5 kW | 13.39¢ |

What does the Mississippi trend mean for a savings estimate?
Over the same years the Mississippi residential price went from 11.32¢ to 13.39¢ per kWh, up 18%, and the average system from 26.3 kW to 5.5 kW. With Mississippi prices up 18% across ten years, a savings estimate that assumes steep yearly rate rises is assuming more than this record shows.
How big is a typical Mississippi system?
The average Mississippi system was 5.5 kW in 2024, the 6th-lowest of 51, against 6.74 kW nationally. Mississippi homes used 13,871 kilowatt-hours a year each, the 2nd-highest of 51.
A Mississippi home using 13,871 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 Mississippi?
Form EIA-861 reports no third-party-ownership split for the 1,789 systems counted in Mississippi in 2024, so we publish none rather than infer one.
Ask any Mississippi company in writing whether it is selling you the system or a lease or power purchase agreement; the owner of a Mississippi system is the one who claims any tax credit.
Do Mississippi homes add batteries?
In Mississippi, 0.61% of solar systems were paired with a battery in 2024 (11 systems), the 15th-lowest of 47. Mississippi’s share is well under half the national 5.86%.
On reliability, the average Mississippi customer went 607 minutes without power in 2024 counting major storms, and 279 minutes without them. The median state saw 297. Outages in every state.
Whether a battery pays in Mississippi 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 Mississippi?
We found no dedicated state register for solar work in Mississippi, so we publish no company counts. That is not evidence of light regulation: electrical work can be licensed at state or local level even where solar is never named.
With 1,789 systems in Mississippi, the company quoting you may be based out of state. Ask which license it holds, in which state, and confirm it with that authority. What to do when the search comes back empty.

Where do the Mississippi numbers come from?
The Mississippi figures are HyreSolar calculations from the Form EIA-861 annual files: 1,789 net-metered residential systems counted against 1,340,459 residential accounts, sizes as means, and 40 utility-level rows for the utility table, matched to net-metering records by EIA utility number.
The method and limits cover all 51; the Mississippi row is in the data as a CSV.
No Mississippi 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.
