State Electricity Tariff Slab Comparison Calculator 2026

Electricity tariffs across India vary more than almost any other utility service. Under the Indian Constitution, electricity falls on the Concurrent List, granting each state autonomous regulatory authority through its State Electricity Regulatory Commission (SERC). For an identical monthly consumption of 250 units on a standard 2 kW connected load, a household in Punjab or Delhi pays ₹0 to ₹720 due to aggressive state power subsidies, whereas a family in Uttar Pradesh pays around ₹1,716, and an apartment in Mumbai or Pune under MSEDCL pays nearly ₹2,950. These stark variations stem from local power purchase contracts, transmission wheeling charges, coal transportation distances, and state-specific electricity duty rates ranging from 5% to 16%. This comparison engine standardizes monthly, bi-monthly, and quarterly billing cycles to display true like-for-like costs across all major Indian states.

Step-by-Step Guide

How to Use the Electricity Tariff Comparison Calculator

Input Normalized Monthly Consumption (Units)

Enter your monthly electricity usage in kilowatt-hours (kWh). Use quick presets like 150, 250, or 400 units to compare typical household consumption profiles.

Specify Sanctioned Connected Load (kW)

Select your sanctioned load (1 kW, 2 kW, 3 kW, or 5 kW). Fixed demand charges scale directly with sanctioned capacity across states like Karnataka, Maharashtra, and Uttar Pradesh.

Choose Subsidy Inclusion Mode

Toggle between active government welfare subsidies (such as Punjab 300-unit exemption, Delhi partial subsidies, and Tamil Nadu 100 free units) and pure base commercial tariffs.

Examine Normalized State Rankings and Slab Surcharges

Review the comparative breakdown from lowest to highest total bill, identifying which states levy heavy additional wheeling fees, fuel adjustment charges (FPPPA/FCA), or municipal duties.

Multi-Cycle Normalization Architecture

Electricity distribution companies across India operate on differing meter-reading cycles. Directly comparing a 60-day bi-monthly bill from Tamil Nadu or Kerala against a 30-day monthly bill from Delhi or Maharashtra leads to mathematical errors. We normalize consumption and slab boundaries to a standardized 30-day period:

Monthly DISCOMs (30 Days)

Delhi, Maharashtra, UP, Karnataka, Telangana, Assam

Normalized Bill = Direct 30-day calculation

Bi-Monthly DISCOMs (60 Days)

Tamil Nadu (TNEB), Kerala (KSEB), Punjab (PSPCL)

Normalized Bill = 60-day Bill (2x Units) ÷ 2

Quarterly DISCOMs (90 Days)

West Bengal (WBSEDCL)

Normalized Bill = 90-day Bill (3x Units) ÷ 3

Frequently Asked Questions

Under Entry 38 of the Concurrent List in the Seventh Schedule of the Indian Constitution, electricity is regulated jointly by central and state governments. Each state has an autonomous State Electricity Regulatory Commission (SERC) that sets retail tariffs. Landlocked states far from coal mines incur high freight costs, while states with abundant hydro or local pithead thermal plants enjoy lower generation costs. In addition, state governments choose different levels of budgetary subsidies to absorb power costs for low-income and agricultural consumers.

MSEDCL bills three distinct components that compound total costs: an escalating base energy slab rate reaching up to ₹12.50 per unit, a separate wheeling charge of ₹1.60 per unit added to every kilowatt-hour consumed, and a 16% state electricity duty, which is the highest domestic duty rate in India. In addition, high cross-subsidies for agricultural pumping place a heavy financial recovery burden on residential and commercial consumers.

Tamil Nadu (TNEB), Kerala (KSEB), and Punjab (PSPCL) bill residential consumers on a 60-day bi-monthly schedule, while West Bengal (WBSEDCL) reads meters quarterly (90 days). Comparing raw bills would distort true monthly costs. To normalize, our engine multiplies a 30-day monthly input by 2 for bi-monthly states (or by 3 for quarterly states), evaluates the bill across the official multi-month telescopic slab structure, and divides the final amount by 2 (or 3) to yield an exact, mathematically consistent 30-day cost.

The Gruha Jyothi scheme in Karnataka is a hard cliff subsidy capped at 200 units. If your monthly usage remains under your calculated 12-month average entitlement limit (up to a hard ceiling of 200 units), your net bill is zero. If you cross 200 units by even a single kilowatt-hour (e.g. 201 units), the subsidy is 100% revoked. You must pay the full unsubsidized bill for all 201 units at ₹5.80 per unit, along with fixed demand charges of ₹150 per kW and 9% state electricity duty.

FPPPA (Fuel and Power Purchase Price Adjustment), also known as FAC or FPPCA, is a variable surcharge that utilities adjust quarterly or monthly to pass through fluctuations in imported coal, railway freight, and spot power purchase market rates. Even if base SERC slab rates remain unchanged, a rising FPPPA rate of 35 paise to ₹1.10 per unit can increase your final bill by 5% to 15% without prior legislative announcement.

Yes. Fixed demand charges (measured in ₹ per kW per month) are billed regardless of whether you consume any electricity. In Uttar Pradesh, 2 kW domestic load incurs ₹220 per month in fixed demand fees alone. In Maharashtra, fixed charges reach ₹135 to ₹185 per connection, and Karnataka charges ₹150 per kW. If your sanctioned load is 5 kW but your peak concurrent usage never exceeds 2 kW, you are paying hundreds of rupees every month for idle contracted capacity.
