Is your Mississippi Power commercial bill right?

Every large commercial account on Mississippi Power is due a $2,185 credit each month through December 2027, and every small commercial account $10. The Commission ordered it on June 18, 2026. Is it on your bill? Meanwhile the adjustment factors stack to about 5.6¢ on every small-business kWh, an ad valorem tax charge of almost a penny per kWh started in September, and the fuel factor resets again in February with $31 million of deferred costs waiting behind it. Nobody at Mississippi Power checks whether your bill reconstructs from the tariff. OptivAI does, every cycle, with a dedicated AI Energy Expert on your account, a rate-plan verdict each month and an Optimization Roadmap built from how your building actually runs. $99 per account per month. No equipment, no audit, nothing to install.

Tariff basis: Mississippi Power Company rate schedules effective June 18, 2026 (MPSC Schedules 3.1 to 5.2, 45 and 47) and adjustment factor bulletins in force for the November 2026 billing month. Last reviewed by OptivAI on November 11, 2026.

The two questions every Mississippi Power business owner eventually types

1. Is my Mississippi Power bill right?

A Mississippi Power commercial bill is a base schedule plus a stack of separately ordered factors, each on its own calendar. The Fuel Cost Recovery and Energy Cost Management factor resets every February (3.6423¢ per kWh for general service accounts since February 2026). The Environmental Compliance Overview factor resets in May (0.8837¢). The System Restoration Rider resets in July (0.0962¢). The Ad Valorem Tax Adjustment began in September at 0.9927¢ per kWh. The Regulatory Tax Recovery assessment resets in November as a flat monthly charge ($1.17 small commercial, $389.64 large). And from July 2026 through December 2027 a fixed excess deferred tax credit is supposed to appear every month: $10.00 on small commercial accounts, $2,185.00 on large ones. The schedule itself prices energy in hours-use blocks tied to your own demand, so the kWh price depends on the kW.

OptivAI rebuilds the bill from the filed schedule each cycle, applies each factor and credit in force for that billing month and your rate class, checks the billing requirement against the ratchet and the contract minimum, and compares the result with what was charged. Anything that does not reconstruct is flagged, in plain language, in your portal.

2. Am I on the right Mississippi Power rate plan?

Mississippi Power's schedules are split by voltage and by size, not by a single demand threshold. GS-LVS and GS-LVT serve single-phase and three-phase service under 600 volts; GS-HV serves anything above it. LGS-LV and LGS-HV are the large general service schedules, with a 500 kVA floor on the billing requirement and a five-year minimum term. LGS-TOU and LPO-TOU are time-of-use with on-peak and excess kVA charges and energy priced by hour. Because the energy blocks break at 200 and 400 hours-use of demand, a long-hours building on GS-LVT and a short-hours building on LGS-LV can both be on the wrong schedule for opposite reasons.

Every cycle OptivAI compares your actual usage against each schedule your account is eligible for and delivers a verdict: stay, or switch and why. Where a switch makes sense, you see the projected difference, labelled Projected until your own bill proves it. Mississippi Power makes the change; we make sure you know to ask for it.

The Mississippi Power rate schedules we read

These are the Mississippi commercial schedules in OptivAI's Mississippi Power tariff catalog, read from the rate schedules effective June 18, 2026 as filed with the Mississippi Public Service Commission. Electric heating (GSEH and LGS-EH), standby, lighting, pumping, church and school riders and special contracts are reviewed account by account.

Billing demand in kVA: why one afternoon in August is still on your bill next May

On LGS-LV and LGS-HV the billing requirement is the highest 15-minute kVA of the month, but it can never fall below three floors: 75 percent of the greatest kVA set during the preceding May through October, 75 percent of contracted kVA (85 percent of contracted kW), and 500 kVA. On LGS-TOU and LPO-TOU the on-peak kVA requirement carries a 75 percent ratchet to the preceding June through September. The bill shows one kVA figure and does not say which floor produced it.

kVAMississippi Power bills demand in kVA, not kW. A power factor of 0.85 adds about 18 percent to the billing requirement before any ratchet applies.
75%Of the greatest kVA set during the preceding May through October, for every month until the next summer resets it.
500 kVAThe floor on LGS-LV and LGS-HV, and 75 percent of contracted kVA if that is higher. On LPO-TOU the floor is 10,000 kVA.
200 / 400Hours-use breakpoints: energy is priced in blocks of 200 and 400 hours times the billing requirement, so a higher kVA also reprices every kWh.

The hours-use structure is what makes the ratchet expensive. On LGS-LV the first 200 hours of energy per kVA cost 3.088¢, the next 200 hours 2.687¢ and everything beyond 0.923¢; a ratcheted kVA pushes more of your kWh into the expensive blocks at the same time it raises the demand charge. On GS-LVT the effect is sharper still, 8.992¢ against 0.979¢. OptivAI tracks the billing requirement month by month, shows you which floor is setting it, and tells you when a single avoidable summer peak, a low power factor or an oversized contract kVA is the reason. That is where the Optimization Roadmap begins.

What rides on top of the rate

The base schedule is only part of the price. These are the adjustment factors and credits in force for the November 2026 billing month, read from Mississippi Power's adjustment factor bulletins. For a general service account the per-kWh factors total 5.6149¢; large general service and LPO-TOU accounts carry slightly lower per-kWh factors and much larger fixed monthly items.

Fuel Cost Recovery and Energy Cost Management (FCR-2, ECM-2A)

3.6423¢ per kWh for general service, 3.5580¢ for LGS, LGS-EH, LGS-TOU and T-LP, 3.4805¢ for LPO-TOU, from the February 2026 billing month (MPSC order of January 13, 2026, Docket 2025-UN-114). The largest adder and the one that resets each February.

Environmental Compliance Overview (ECO-3)

0.8837¢ per kWh for general service, 0.8676¢ for LGS classes, 0.8465¢ for LPO-TOU, from the May 2026 billing month (order of April 14, 2026). Resets annually in May.

Ad Valorem Tax Adjustment (ATA-2)

0.9927¢ per kWh on all retail classes from the September 2026 billing month (order of August 4, 2026, Docket 2025-UN-062). Nearly a cent per kWh that was not on last year's bills in this form.

System Restoration Rider (SRR-2)

0.0962¢ per kWh for general service, 0.0940¢ for LGS classes, 0.0923¢ for LPO-TOU, from the July 2026 billing month (order of June 18, 2026). Funds the storm restoration reserve.

Regulatory Tax Recovery (RTR-2)

A flat monthly assessment, not a per-kWh factor: $1.17 per month for small commercial and industrial accounts and $389.64 per month for large commercial and industrial accounts, from the November 2026 billing month (order of October 6, 2026, Docket 2026-UN-61).

Excess deferred income tax credit

A credit, not a charge: ($10.00) per month for GS, GS-EH, GP and T accounts and ($2,185.00) per month for LGS, LGS-EH, LGS-TOU, LPO-TOU and T-LP accounts, every billing month from July 2026 through December 2027 (order of June 18, 2026, Docket 2025-UA-104). If it is missing, the bill is wrong by that much.

The Mississippi Power landscape, as of this review

Securing your future means watching what the regulator and the utility are doing before it reaches your bill. This is what we are watching for Mississippi Power accounts right now.

  • The Mississippi Public Service Commission approved Mississippi Power's annual fuel filing (Docket 2025-UN-114): retail fuel revenues up about $40 million a year from the February 2026 billing month, with roughly $31 million of costs under-recovered as of October 2025 deferred into the next fuel filing rather than collected now. That deferred balance is still owed and comes back in the February 2027 reset. (UtilityRateWatch, Mississippi Power rate book)
  • The Commission approved the 2026 Performance Evaluation Plan report (Docket 2019-UN-219), making permanent the 1.8 percent, about $20 million, base-rate increase that had been in effect subject to refund since January; new versions of every commercial schedule took effect the same day. In the same meeting it ordered about $21 million of excess deferred income taxes returned as fixed monthly credits from July 2026 through December 2027, and approved the 2026 System Restoration Rider factors. (MPSC June 18, 2026 agenda, UtilityRateWatch)
  • The Commission approved the Ad Valorem Tax Adjustment Clause factor (Docket 2025-UN-062): 0.9927¢ per kWh on retail bills from the September 2026 billing month. (Mississippi Power rate book)
  • The Commission approved the Regulatory Tax Recovery Clause assessments for the year beginning with the November 2026 billing month (Docket 2026-UN-61): $1.17 per month for small commercial and industrial accounts, $389.64 per month for large. (MPSC October 6, 2026 agenda)
  • On or about this date each year, under the Performance Evaluation Plan, Mississippi Power files its preliminary report saying whether a base-rate adjustment is needed for the coming year; any interim change starts with the first January billing cycle, subject to refund, with the full evaluation report due by March 15 and a final order expected in the second quarter. We will read the filing the day it posts. (Mississippi Power PEP-7 schedule)
  • The annual Fuel Cost Recovery and Energy Cost Management factors reset with the February billing month, carrying the deferred under-recovery from the 2026 filing. The Commission's November 2026 Power Grid Summit heard warnings that data-center load could push Mississippi rates higher; the Compass Datacenters special contract approved in February 2025 is the first large one in this territory. We track both as pending until they reach a filed factor. (Tallahatchie News, American Public Power Association)

Your Mississippi Power Energy Fingerprint

No two buildings bill alike, and an industry average is not your building. Over twelve cycles OptivAI builds your account's Energy Fingerprint from your Mississippi Power data and the facility profile you give us at onboarding: operating hours, major equipment, load drivers and goals. On Mississippi Power that means learning the kVA, not kW, that set your billing requirement, how much of it is power factor, where your hours-use lands against the 200 and 400 hour blocks, and whether the monthly tax credit is on your bill.

An audit looks once. A Fingerprint learns. It is proprietary to your account, it lives in your portal, and it is the reason your Optimization Roadmap is specific to how your building runs instead of a list of generic tips.

Cycle 1Your first bill rebuilt and verified, your rate-plan verdict, and a Starting Roadmap. The Fingerprint begins.

Mississippi Power questions we are asked

How do I know if my Mississippi Power commercial bill is correct?

OptivAI rebuilds each Mississippi Power bill from the filed rate schedule for your account (GS-LVS, GS-LVT, GS-HV, LGS-LV, LGS-HV, LGS-TOU or LPO-TOU), applies the hours-use blocks to your own kW or kVA billing requirement, adds the Fuel Cost Recovery and Energy Cost Management factor, the ECO-3, SRR-2 and ATA-2 per-kWh factors, the RTR-2 monthly assessment and the excess deferred tax credit in force for that billing month, checks the billing requirement against the summer ratchet and the contract minimum, and compares the result line by line with what you were charged. Anything that does not reconstruct is flagged in plain language every cycle.

Is the $2,185 monthly tax credit on my Mississippi Power bill?

It should be. Under the Mississippi Public Service Commission's June 18, 2026 order in Docket 2025-UA-104, Mississippi Power is returning excess accumulated deferred income taxes as a fixed monthly credit from the July 2026 billing month through December 2027: $10.00 per month for small commercial and industrial accounts (GS, GS-EH, GP, T) and $2,185.00 per month for large commercial and industrial accounts (LGS, LGS-EH, LGS-TOU, LPO-TOU, T-LP). OptivAI checks for it on every bill in the window and tells you if it is missing or the wrong size.

Am I on the right Mississippi Power rate plan for my business?

Every cycle OptivAI compares your actual usage and demand against the Mississippi Power schedules your account is eligible for and delivers a verdict: stay, or switch and why. Common questions are whether a GS-LVT account that runs long hours would do better on LGS-LV, whether an account carrying a 500 kVA floor on LGS is paying for capacity it no longer uses, whether a building with evening and weekend load fits LGS-TOU, and whether a five-year LGS term is worth signing. Projected differences are labelled Projected until your own bill proves them.

What is the Mississippi Power demand ratchet?

On LGS-LV and LGS-HV the monthly kVA billing requirement is the highest 15-minute kVA of the month, but never less than 75 percent of the greatest kVA set during the preceding May through October, nor less than 75 percent of contracted kVA, nor less than 500 kVA. On LGS-TOU and LPO-TOU the on-peak kVA billing requirement is never less than 75 percent of the highest on-peak kVA from the preceding June through September. Because Mississippi Power bills in kVA rather than kW, a poor power factor raises the billing requirement directly. One summer afternoon can set a floor under your demand charges until the following summer.

What changes on Mississippi Power bills in early 2027?

Two things on a schedule. Around November 15 each year Mississippi Power files its Performance Evaluation Plan preliminary report, and any interim base-rate change begins with the first January billing cycle, subject to refund, with the Commission's final decision in the second quarter; the 2026 round was a 1.8 percent, $20 million increase. And the annual Fuel Cost Recovery and Energy Cost Management factors reset with the February billing month; about $31 million of fuel costs under-recovered as of October 2025 was deferred into this next filing. OptivAI applies the new factors the month they take effect and shows you the before-and-after on your account.

What is a Mississippi Power Energy Fingerprint?

Your Energy Fingerprint is OptivAI's 12-month model of how your Mississippi Power account uses and is billed for electricity, built month by month from your utility data and the facility profile you give us at onboarding. On Mississippi Power that means learning the kVA, not kW, that set your billing requirement, how much of it is power factor, where your hours-use lands against the 200 and 400 hour blocks, and whether the monthly tax credit is on your bill. Your Starting Roadmap arrives in your first cycle and sharpens every month; at month 12 the Fingerprint becomes your full Optimization Roadmap, specific to your account and labelled Projected until your bill proves it.

How much does OptivAI cost for a Mississippi Power account?

$99 per utility account per month for one to five accounts, $89 per account at six or more, on a 12-month term billed monthly. No equipment, no installation, no shared-savings split. A Starting Roadmap in your first cycle and the full Optimization Roadmap at month 12.

Do you need my Mississippi Power login?

No. You connect your account through a read-only utility connection or upload your bills. OptivAI never sees or stores a utility login.

Is it worth $99 to make sure your company's energy future is secure?
