What Are the Official State-Wise Electricity Tariff Rates & Slabs in India (2026)?

Official State Electricity Regulatory Commission (SERC) tariff schedules, domestic telescopic slabs, lifeline subsidies, and regulatory order references across Indian DISCOMs.

Under the Electricity Act 2003, retail electricity tariffs in India are regulated and determined annually or multi-year by State Electricity Regulatory Commissions (SERCs). Tariffs follow telescopic slab mechanisms designed to offer subsidized lifeline electricity to low-consumption households while charging higher rates for higher consumption slabs. Compare the verified 2026 domestic tariffs, effective dates, fixed charges per kW, and official regulatory orders across major state boards below.

Transparent Methodology

How Electricity Bills Are Calculated in India

Unlike fixed-rate utilities, Indian DISCOMs compute power charges based on multi-component regulated tariff orders.

⚡

How Electricity Bill is Calculated in India (Official Formula)

An Indian electricity bill is calculated as: Total Net Bill = (Units Consumed × Progressive Slab Rates) + Fixed Demand Charges + Electricity Duty/Tax (5%–16%) + FPPPA/Fuel Surcharge − Eligible Subsidies.

1. Energy Charges Units partitioned by telescopic slabs at escalating rates.
2. Fixed / Demand Charges Monthly connected capacity fee based on sanctioned load (per kW).
3. Taxes & Adjustments State government duty percentage plus quarterly fuel rate adjustment (FPPPA).
1

Telescopic Slabs

Units consumed are split across progressive slab tiers, rewarding lower consumption with subsidized baseline rates.

2

Fixed & Demand Charges

Mandatory monthly or bi-monthly connection fees assessed on sanctioned load (kW/kVA) regardless of usage.

3

Electricity Duty & Tax

Statutory state taxes (5% to 16%), regulatory surcharges, and local municipal power cess.

4

Government Subsidies

Free lifeline units (e.g. Tamil Nadu 200u free, Delhi subsidy, Punjab 300u) automatically credited before final net bill.

Help & Knowledge

Frequently Asked Questions

In India, your monthly electricity bill consists of five primary components: base energy charges calculated using state telescopic or flat consumption slabs, fixed or demand charges based on your sanctioned connected load (per kW), wheeling and transmission charges, state electricity duty and taxes (typically 5% to 16% depending on the state), and monthly fuel surcharge adjustments (FPPPA/FAC). Any eligible government lifeline subsidies (such as free unit quotas) are deducted from the gross amount to arrive at your net payable bill.
Under telescopic tariff slabs (used by states like Maharashtra, Tamil Nadu, and Karnataka), your consumption is divided into successive blocks (e.g., first 100 units at a lower rate, next 100 units at a higher rate). In non-telescopic slabs (used by Kerala for high consumption), crossing a consumption threshold recalculates all consumed units from unit 1 at the higher slab rate, causing a sharp bill increase.
Electricity distribution is regulated at the state level by State Electricity Regulatory Commissions (SERCs) rather than the central government. Power generation mix (thermal, hydro, solar), power purchase agreement costs, distribution infrastructure losses (AT&C losses), and state government subsidy schemes (like Gruha Jyothi in Karnataka, 300 free units in Punjab, or Delhi DERC subsidy) differ significantly by state and DISCOM.
Fixed or demand charges represent the recurring infrastructure cost of maintaining power grid availability to your property regardless of actual energy consumed. They are billed monthly or bi-monthly based on your sanctioned connected load in kilowatts (kW) or kilovolt-amperes (kVA). For example, a 2 kW domestic connection with a fixed charge of ₹50/kW incurs ₹100 per month in fixed charges even with zero units consumed.
The PM Surya Ghar scheme provides a central government capital subsidy of up to ₹78,000 for installing grid-tied residential rooftop solar systems (up to 3 kW). Generated solar energy is fed through a bi-directional net meter. On sunny months, your rooftop system can offset your entire daytime electricity consumption, effectively reducing your monthly power bill to only the minimum fixed demand charges.
To calculate units consumed for your billing period, take your current meter reading in kWh (kilowatt-hours) displayed on your digital or smart meter, and subtract the previous meter reading recorded on your last electricity bill. The difference equals your net units consumed (1 kWh = 1 unit of electricity). If your utility uses a Power Factor (PF) or Multiplier Factor (MF) for commercial connections, multiply the difference by the designated factor.
