Delhi Electricity Tariff Structure & Billing Rules
Domestic electricity bills across the National Capital Territory (NCT) of Delhi are governed by tariff orders issued by the Delhi Electricity Regulatory Commission (DERC) and billed by individual distribution licensees: BSES Rajdhani Power Limited (BRPL), BSES Yamuna Power Limited (BYPL), Tata Power Delhi Distribution Limited (TPDDL), and NDMC.
1. Domestic Telescopic Energy Slabs
Domestic energy consumption is billed on a progressive telescopic scale. If your monthly consumption is 250 units, the first 200 units are billed at the base slab rate (₹3.00/unit), and only the remaining 50 units are charged at the next tier (₹4.50/unit):
| Consumption Slab (kWh / Units) | Energy Rate (₹/kWh) | Billing Calculation |
|---|---|---|
| 0 – 200 Units | ₹3.00 | Telescopic Base Tier |
| 201 – 400 Units | ₹4.50 | Telescopic Second Tier |
| 401 – 800 Units | ₹6.50 | Standard Rate |
| 801 – 1200 Units | ₹7.00 | Higher Consumption Tier |
| Above 1200 Units | ₹8.00 | Maximum Domestic Tier |

Frequently Asked Questions (FAQ)
1. What is the electricity bill for 200 units in Delhi?
For opted-in domestic consumers, monthly consumption up to 200 units results in a ₹0 bill under the 100% subsidy scheme. If not opted in, the gross payable amount (including fixed charges and taxes) is typically between ₹800 and ₹950 depending on sanctioned load.
2. What happens if consumption reaches 201 units?
Crossing 200 units moves the connection into the 201–400 bracket. The 100% full waiver is replaced by a 50% subsidy on energy charges (capped at ₹800), and the consumer pays the remaining energy balance plus fixed charges, surcharges, and taxes.
3. What happens if consumption exceeds 400 units?
If consumption reaches 401 units or higher, the entire subsidy is withdrawn. The consumer pays full energy charges across all slabs plus all statutory surcharges and taxes.
4. What does NDLT mean on an electricity bill?
NDLT stands for Non-Domestic Low Tension, which denotes commercial or office connections. NDLT connections are not eligible for domestic subsidies and are billed under higher commercial tariff schedules.
