State Electricity Boards Tariff Rates, Slabs & Order Dates (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 determined by State Electricity Regulatory Commissions (SERCs). Most utilities apply telescopic slab pricing, where consumed units are split across successive price tiers to subsidize low-consumption families while penalizing excessive load. Below is the verified directory of domestic tariff orders, effective dates, slab rates, and government lifeline schemes across major Indian electricity boards.

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.

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

Our platform uses the exact official tariff orders published by each State Electricity Regulatory Commission (SERC). When you enter your consumed units and select your electricity provider, the engine breaks down the units across regulated telescopic slabs, calculates fixed kW demand charges, applies state taxes and fuel surcharges, and subtracts any eligible government subsidies to provide a detailed estimate.
In a telescopic system, your electricity consumption is divided across lower-priced and higher-priced slabs progressively. For example, if you consume 150 units in a state with slabs 0-100 @ ₹3 and 101-200 @ ₹5, your first 100 units are billed at ₹3, and only the remaining 50 units are charged at ₹5. This rewards lower power consumption.
Physical utility bills often incorporate monthly fuel adjustment surcharges (FPPPA / FAC) that fluctuate each quarter, municipal taxes, electronic payment rebates, meter testing fees, or previous arrears. Our calculator reflects the published base tariff order and standard state duties.
