Delhi Electricity Bill Calculator 2026
To calculate your Delhi electricity bill across BSES Rajdhani (BRPL), BSES Yamuna (BYPL), or Tata Power-DDL (TPDDL): under DERC tariff regulations and Delhi Government subsidy schemes, residential consumers using ≤200 units pay ₹0 (100% full waiver). Consumption between 201 and 400 units receives a 50% energy subsidy (up to ₹800/month). For usage above 400 units, progressive DERC slabs apply (₹6.50 to ₹8.00/unit) along with sanctioned load fixed charges (₹20 to ₹250/kW), 8% Regulatory Surcharge, 7% Pension Surcharge, 5% Electricity Duty, and DISCOM-specific PPAC fuel adjustments (revised monthly by DERC; confirm rate on your bill).
Distributor Notice: Delhi has three electricity distributors (BRPL, BYPL, TPDDL) with different operational territories and monthly fluctuating PPAC surcharges. This calculator serves as a unified Delhi Hub: it uses DERC's uniform domestic base slabs (₹3.00–₹8.00/unit) and 200 free units subsidy, and allows you to view published division coverage and bill guidelines for each distributor.
⚠️ Regulatory Transparency & Verification Note: DERC has not issued a new comprehensive tariff order for FY 2026-27; base slabs remain extended under DERC Business Plan Regulations. PPAC surcharges are revised monthly by DERC (reported ranges have spanned 15%–31% across billing cycles). Because monthly PPAC fluctuates, this calculator computes confirmed base DERC rates and government subsidies, displaying PPAC as a separate variable item. Confirm your exact DISCOM and current month's PPAC on your electricity bill.
Delhi BSES / Tata Power Power Bill Calculator
Multi-Utility Structure: All three Delhi DISCOMs operate under the same DERC base domestic tariff slabs (₹3.00–₹8.00/unit) and the Delhi Government 200 free units subsidy.
⚠️ PPAC NOTICE (CONFIRM WITH BILL): Power Purchase Adjustment Cost (PPAC) is revised monthly by DERC (reported ranges have spanned 15%–31% across billing cycles). Because PPAC changes on every monthly invoice, this tool calculates confirmed base DERC slab rates and subsidies, displaying PPAC as a variable monthly line item.
Final bill is rounded to the nearest rupee for display. Line items may not sum exactly due to rounding.

How is Electricity Bill Calculated in Delhi?
In Delhi across BSES Rajdhani (BRPL), BSES Yamuna (BYPL), and Tata Power DDL (TPDDL), electricity bills are calculated monthly under DERC regulations with Delhi Government power subsidies. Domestic households consuming up to 200 units per month receive a 100% subsidy, resulting in a ₹0 net electricity bill. For consumption between 201 and 400 units, the Delhi Government provides a 50% energy subsidy (up to a maximum of ₹800). For monthly usage above 400 units, full DERC progressive rates apply: ₹6.50 for 401–800 units, ₹7.00 for 801–1200 units, and ₹8.00/unit for consumption above 1,200 units, alongside low fixed load charges of ₹20/kW/month, PPAC fuel surcharge, and 5% electricity tax.

Delhi Electricity Distributors (DISCOMs) & Neighborhood Directory
CONFIRM WITH YOUR BILLDelhi electricity distribution is divided geographically across three primary distribution licensees under DERC oversight.
1. Division Boundaries: Neighborhood mappings are drawn from operational division lists published on bsesdelhi.com (BRPL 23 divisions, BYPL 14 divisions) and tatapower-ddl.com (TPDDL 12 divisions). Boundary fringes may overlap. Always verify your distributor directly from your electricity bill's Consumer Account (CA) number.
2. PPAC Surcharge Fluctuation: DERC transitioned in 2026 to a monthly review and revision process for the Fuel and Power Purchase Adjustment Surcharge (FPPAS/PPAC). The percentages below (e.g. ~17.4%–18.5% in recent monthly orders) are illustrative recent proxies, not fixed annual rates. Check the exact PPAC line item on your monthly bill.

Understanding Your Delhi Electricity Bill: Surcharges & PPAC Explained
Delhi electricity bills are unique because while base energy rates and fixed charges are 100% uniform across all three DISCOMs, your bill includes statutory surcharges and variable fuel adjustments approved by the Delhi Electricity Regulatory Commission (DERC).
1. Power Purchase Adjustment Cost (PPAC)
PPAC is a variable monthly/quarterly surcharge approved by DERC to compensate DISCOMs for fluctuations in coal, gas, and power purchase market costs. It is calculated as a direct percentage on (Energy Charges + Fixed Charges). Because each DISCOM has a different generation contract mix, their PPAC rates differ:
- BRPL (South & West Delhi): Revised monthly by DERC based on bilateral power procurement.
- BYPL (East & Central Delhi): Revised monthly by DERC based on bilateral power procurement.
- TPDDL (North & North-West Delhi): Revised monthly by DERC based on long-term PPA costs.
- Note: Recent PPAC surcharges have ranged 15%–31% across billing cycles. Check line item "PPAC" on your latest bill for your active rate.
2. Statutory DERC Surcharges & Taxes
Mandatory government levies added to residential bills across all Delhi distribution companies:
- 8% DERC Regulatory Surcharge: Dedicated to liquidating past accumulated regulatory assets.
- 7% Pension Trust Surcharge: Funding the statutory pension obligations of erstwhile Delhi Vidyut Board (DVB) retirees.
- 5% Delhi Electricity Duty: Statutory tax levied by the Municipal Corporation of Delhi (MCD).

Common queries answered regarding Delhi electricity tariffs, slabs, and billing rules.
Is electricity really free in Delhi up to 200 units? ▼
Yes, under the Delhi Government subsidy scheme, domestic consumers who opt-in for power subsidy pay ₹0 if their consumption is 200 units or less.
How much is 300 units electricity bill in Delhi? ▼
For 300 units in Delhi, the gross energy charge is ₹1,050. With the 50% subsidy (₹525 rebate) plus fixed charge and taxes, your net payable bill is approximately ₹650 to ₹785 depending on your DISCOM's PPAC surcharge.
What is PPAC in Delhi electricity bill? ▼
PPAC stands for Power Purchase Adjustment Cost. It is approved quarterly by DERC to compensate DISCOMs for fluctuating coal, gas, and power procurement prices.
Why do electricity bills differ between BSES Rajdhani, BSES Yamuna, and Tata Power-DDL? ▼
While DERC mandates the exact same base domestic energy slabs (₹3.00 to ₹8.00/unit) and 200 free units subsidy across all Delhi DISCOMs, each utility has different power procurement contracts. DERC approves different Power Purchase Adjustment Cost (PPAC) surcharges for each distributor, revised on a monthly basis (recent cycles have spanned 15%–31%). Always check the PPAC line item on your latest bill for the active rate.
