Delhi Electricity Bill Calculator

Yes, if your monthly consumption is 200 units or less, you get a 100% subsidy on energy charges, making your net energy bill zero.

For residential connections, the fixed capacity charge is based on your sanctioned load (in kW). It is calculated by multiplying your load by the DISCOM's monthly rate per kW (ranging from Rs. 20 to Rs. 145 depending on the state). It remains constant regardless of whether you consume any electricity.

A telescopic slab structure means your consumption is divided into blocks (e.g., 0–100 units, 101–200 units), with each block billed at a different per-unit tariff. Consuming even 1 unit above a slab threshold can push you into a higher rate band, causing your bill to increase.

Yes, state governments levy an electricity duty (tax) ranging from 5% to 16% on your total energy and fixed charges. Additionally, municipal taxes, green energy cesses, and variable surcharges like FPPCA are added to the final amount.

Fuel Power Purchase Cost Adjustment (FPPCA) is a variable surcharge representing fluctuations in fuel (coal/gas) prices and power purchase costs. It is updated quarterly or monthly by state regulators and typically ranges from 10 paise to 80 paise per unit.

Rooftop solar exports power back to the grid under net-metering. Your monthly units are offset by the solar export units. If your 3 kW solar system exports 300 units and you consume 300 units, your net consumption is 0 units, leaving you with only basic fixed charges.

Single phase supply is standard for loads up to 5 kW (small homes), while three phase supply is required for larger loads (above 5 kW) to balance heavy appliances like ACs and water pumps. Fixed capacity charges are significantly higher for three phase connections.
