Current Rate Schedules
Entergy Louisiana C&I rates are set by LPSC-approved tariff schedules under its Formula Rate Plan. Bills combine a customer charge, energy (kWh) charges, demand (kW) charges for larger schedules, and pass-through fuel and rider components. Exact cents-per-kWh and per-kW figures vary by schedule, season, and the annually updated FRP rider, so they are described structurally here; consult the official LPSC tariff book and the C&I tariff pages for current values. The figures below are structural; verified dollar magnitudes appear in Historical Rates (FRP changes).

Rate Recommendations by Use Case
Mid-size commercial facility (office, retail, light industrial)
Get on the right schedule and control demand charges.
LGS introduces meaningful demand (kW) charges; right-sizing the schedule and shaving peaks materially affects the bill, while SGS suits smaller loads with little demand.
- Pull 15-minute data from myAdvisor or DataLink to find peaks
- Confirm SGS vs LGS classification matches your demand
- Shift flexible loads off coincident peak periods
Large industrial plant
Minimize demand-driven cost and consider voltage-level service.
For large loads, demand and contract-demand charges dominate; taking service at primary/transmission voltage and improving load factor reduce unit cost.
- Request DataLink for detailed 15-minute interval analysis
- Evaluate higher-voltage service for available discounts
- Manage contract demand to actual need
C&I customer automating data and AP
Stand up automated billing and interval data feeds.
Entergy supports EDI 810 invoicing and Green Button Connect (ESPI/OAuth), so C&I customers and their vendors can automate both billing and 15-minute interval data.
- Enroll in EDI 810 via the Entergy Business Center
- Use Green Button Connect or Nectar (docs.nectarclimate.com) for programmatic usage data
- Map invoice segments into your AP/energy system
Sustainability-focused C&I buyer
Add renewable supply without leaving the regulated utility.
Louisiana has no retail choice, but the Geaux Green C&I subscription lets businesses procure renewable energy through Entergy while staying on their tariffed schedule.
- Review Geaux Green C&I plans and pricing
- Pair with interval data to document load and green coverage
- Track FRP-driven base-rate changes annually
Historical Rate Trends
Entergy Louisiana base rates adjust primarily through its LPSC-approved Formula Rate Plan (FRP), which the Commission extended for three additional years in August 2024. Annual FRP filings adjust rates within a bandwidth around a target return on equity (10.0% in the current plan), on top of fuel and rider changes.
August 14, 2024
The LPSC approved a three-year extension of Entergy Louisiana's Formula Rate Plan. The filing sought roughly a $173 million electric revenue-requirement increase phased over the plan term; the average residential customer (1,000 kWh) was projected to see about a 5.6% / $6.75 monthly increase if fully implemented as proposed, with a 10.0% target ROE.
~+5.6% (residential, phased)January 1, 2025
Phased FRP rate adjustment under the extended plan: a roughly $0.57 monthly residential increase in 2025, with annual step-ups continuing (about $2.64 in 2026), reflecting the agreed phase-in schedule.
~+1.8% annual (phased)Overall trend: Steadily rising under the FRP as Entergy recovers capital investment (grid resilience, generation) within an LPSC-approved annual adjustment framework, plus volatile fuel pass-throughs.
Next expected change: Next annual FRP rate adjustment expected in 2026 under the extended three-year plan; phased residential step-ups continue through ~2029.
Cost Optimization Strategies
For C&I customers on Entergy Louisiana, the biggest levers are managing demand (kW), confirming the lowest-cost applicable schedule and voltage level, and using 15-minute interval data to flag and shave peaks.
Manage peak demand
For: LGS and large industrial
On LGS and large industrial schedules, demand (kW) charges are a major cost. Staggering equipment, shifting loads off coincident peaks, and adding storage can cut the billed demand.
Verify schedule and voltage level
For: All C&I
Confirm the account is on the optimal schedule (SGS vs LGS vs large industrial) and, for large loads, take service at higher voltage where discounts apply.
Use DataLink 15-minute interval data
For: Commercial & Industrial
Pull interval data from DataLink (or Green Button) to identify peak intervals, off-hours waste, and load factor opportunities, then target demand reduction.
Automate billing via EDI 810
For: Commercial & Industrial
Adopt EDI 810 invoicing to reduce processing cost, avoid late fees from mail delays, and feed accurate cost data into energy-management systems.
