Does Louisiana charge a demand charge on EV charging?

All three covered rows do, at moderate weights: about $9.43 per kilowatt-month in Baton Rouge, $6.73 in the Jefferson Parish suburbs, and $14.54 in New Orleans, each after the rider stacks fold. New Orleans files an EV-specific demand-relief rider as a capped five-year pilot, which the model discloses but does not assume.

Why do the modeled rates look so different from Entergy's filed base rates?

Because Louisiana's formula rate plans recover most of the revenue requirement through percentage riders on top of base rates — the stacks multiply base revenue by roughly 2.24 to 2.26 on the Entergy Louisiana books and add about 30% in New Orleans. The modeled figures fold every rider at its currently-effective value, verified against the utilities' own bill-calculation examples.

Is there a per-kWh charging tax in Louisiana?

No — none is in force and none was found pending. Louisiana's EV road-funding instrument is a vehicle-side annual fee paid by the driver at registration, which does not touch site economics.

Tesla Supercharger ROI in Louisiana

Louisiana prices electricity in two layers: filed base rates among the cheapest in the covered set, and formula-rate-plan rider stacks that more than double them. The model folds the full multiplier from Entergy's own bill-calculation examples — times 2.24 on the Baton Rouge book, times 2.26 on the Jefferson Parish book — plus trailing-twelve-month fuel factors. New Orleans is its own regulatory island: the City Council regulates Entergy New Orleans, whose storm-reserve rider alone added a quarter to base revenue in January 2026. No charging tax exists, and the vehicle-side road fee belongs to drivers, not sites.

What makes Louisiana economics distinct

The rider stack is the rate

Entergy Louisiana's GS-G book bills base energy near 2.3 cents — and a formula-rate-plan stack that multiplies base revenue by about 2.24 before the fuel factor lands on top. The modeled figures fold every component at its currently-effective value, penny-checked against the utility's own bill examples. The whole multiplier resets at the first September billing cycle, and a redetermination filed May 2026 is in review — the wave's standing re-derive watch.

New Orleans' storm-reserve rider finally published — and moved the row

The bundle-stage research flagged Entergy New Orleans' storm-reserve rider as unpublished; its January 2026 attachment has since posted at +24.6% of base revenue for the large-electric class. Folding it moved the modeled energy rate up 17% and the demand figure up 24% versus the research snapshot — the digit-check catching an understatement before it seeded.

An EV demand-relief rider the model deliberately excludes

Entergy New Orleans files an EV charging demand-adjustment rider that caps billing demand for qualifying stations — but it is a five-year term with a 15-megawatt program cap, first-come. The model excludes it: a capped pilot is not a durable rate, and taking it could only lower the modeled bill.

No charging tax, moderate property tax, repealed franchise tax

Louisiana levies no per-kWh charging tax — the road-funding instrument is a vehicle-side registration fee. Business personal property runs about 1.6% of depreciated cost per year in Baton Rouge and 2% in New Orleans at the 15% assessment ratio, and the state franchise tax is repealed from 2026.

Louisiana tax profile

Sales tax on hardware: 10.5%
Business personal property tax: 1.6% of equipment value (example rate)
Clean-fuels credit: no program
Per-kWh charging excise: none

Louisiana tax defaults applied: no clean-fuels credit program exists in Louisiana (the LCFS revenue line is $0), and LLC costs use the $30 annual report plus an occupational-license estimate — the franchise tax is repealed from 2026 and a pass-through LLC owes no state corporate income tax. Sales tax defaults to Baton Rouge's 10.5% combined rate (New Orleans runs 10%) with no cap, and separately stated installation labor stays outside the base. Business personal property assesses at 15% of value against local millage — about 1.6% of depreciated cost per year in Baton Rouge and 2% in New Orleans. No per-kWh charging tax exists in Louisiana; the road-funding instrument is the vehicle-side registration fee.

Louisiana programs and incentives

Entergy New Orleans — EV Charging Demand Adjustment (Rider EVCDA)

Caps billing demand at kWh÷109.5 for qualifying public charging stations — a five-year term, 15 MW program cap, up to 1,500 kW per account. Excluded from the model as a capped pilot; enrollment could only lower a qualifying site's bill.

NEVI (federal, Louisiana DOTD-administered)

Federal corridor DC fast-charging funding along I-10, I-12, I-20, and I-49, administered in award rounds.

Louisiana charging market

Louisiana carries roughly 21 Supercharger stations along I-10, I-12, and I-20. Entergy Louisiana serves Baton Rouge and Lake Charles on one legacy rate book and the Jefferson Parish suburbs and Hammond on another; Entergy New Orleans serves Orleans Parish under City Council regulation. Shreveport is SWEPCO territory, Lafayette runs its own municipal utility, and Slidell is Cleco — addresses there see a named-utility notice rather than a wrong auto-selection.
