How Indian Electricity Tariffs Work
Indian electricity bills use slab-based tariffs that vary by state. Most states use ascending slabs: 0-100 units at low rate, 101-200 at higher, 201-300 higher still, 301-500 highest, 500+ peak rate. For example, Tamil Nadu (TANGEDCO): 0-100 free, 101-200 ₹2.25/unit, 201-500 ₹4.50, 500+ ₹6.30/unit. Maharashtra (MSEDCL) similar structure with different boundaries.
Beyond energy charges, monthly bills include: fixed charges (₹50-200/month based on connection size), fuel adjustment cost (varies quarterly), electricity duty (5-15% of energy charge in most states), GST 18% on entire bill in some states. So a household at ₹2,000 of energy charges typically pays ₹2,400-2,600 final bill.
Calculating Bill from Meter Reading
Bill = (units consumed × applicable slab rate) + fixed charge + fuel adjustment + duties + GST. A household using 350 units in Tamil Nadu: first 100 free, next 100 at ₹2.25 = ₹225, next 150 at ₹4.50 = ₹675. Energy charge ₹900 + fixed ₹100 + duty ₹90 + GST = ₹1,200-1,300 monthly bill.
Most state utilities (TANGEDCO, MSEDCL, BSES, Adani Electricity, etc.) bill bi-monthly (every 2 months) so the per-bill amounts double. Many homes use 300-600 units monthly in summer with AC; 100-200 units in winter. Annual electricity costs for a 3-BHK family in metro cities typically run ₹15,000-40,000.
Reducing Your Bill
5-star rated appliances use 30-50% less electricity than 1-star equivalents. AC at 24-26°C saves 20-30% vs 18-20°C. Geyser timer (1-2 hours daily instead of always on) saves significantly. LED lights use 80% less than incandescent, 50% less than CFL. Inverter ACs save 30-40% over regular ACs in cooling mode.
Solar rooftop systems are increasingly affordable. 3 kW residential rooftop installation: ₹1.5-2.5 lakh after government subsidy (Rooftop Solar Programme provides 40% subsidy on first 3 kW). Generates roughly 12-15 units/day, often offsetting most household consumption. Payback period 4-7 years; warranty 25 years.
Subsidies and Free Units
Many states offer free or subsidised units for low-consumption households. Tamil Nadu: first 100 units free for all (above), bigger free quota (200 units) for low-income households. Delhi: 200 units free monthly to most households. Punjab: free to farmers (heavily subsidised). Andhra Pradesh, Telangana have similar programmes.
These subsidies are politically sensitive and change with state government policy. Always check your latest bill and the utility's website for current schemes. Income-based subsidies typically require Aadhaar linking and annual income proof. Use the [India Income Tax Calculator](/india-income-tax-calculator) for tax-related queries.
Frequently Asked Questions
How is one 'unit' measured?
One unit = 1 kilowatt-hour (kWh) = 1,000 watts of power consumed for 1 hour. A 100W light bulb running for 10 hours = 1 unit. A 1.5 ton AC running for 1 hour ≈ 1.5 units. Track high-power appliances to estimate consumption.
Why does my bill vary so much month to month?
AC and water heater are the biggest variables. Summer AC use can quadruple electricity consumption vs winter. Holiday months with people home more also increase usage. Bi-monthly billing creates apparent volatility - same monthly average looks more dramatic when bunched.
What's the load demand?
Maximum power your connection can deliver simultaneously, in kVA. Standard residential: 3-5 kVA. Larger homes with multiple ACs: 8-15 kVA. Commercial: higher. Higher load = higher fixed charges. Right-size your connection to your actual peak demand.
Should I install a smart meter?
Many states are rolling out smart meters that show real-time consumption. They can help identify high-usage periods and appliances. Some states charge a small fee; others install free as part of grid modernisation. Smart meter data via apps helps optimise consumption.
