How to Calculate Your Delhi Electricity Bill
Understanding how your Delhi bijli bill is calculated helps you catch overcharges and make the most of the government subsidy. Here's the exact BRPL/BYPL/TPDDL method under DERC.
Read Your Meter
Note down the current meter reading. Subtract the previous month's reading to find units consumed. Your electricity bill also shows this directly as "Units Consumed" in kWh.
Apply Slab Rates (Telescopic)
Delhi uses telescopic billing. Energy = ₹3.00 × units in 0–200 + ₹4.50 × units in 201–400 + ₹6.50 × units in 401–800 + ₹8.00 × units above 800. Example: 500 units = (200×₹3)+(200×₹4.5)+(100×₹6.5) = ₹600+₹900+₹650 = ₹2,150.
Deduct the Delhi Govt Subsidy
If opted in and total consumption ≤200: full energy charge is waived. If 201–400: 200 units free + 50% off the 201–400 portion (max ₹800). If >400: no subsidy on any unit — the entire bill reverts to full tariff.
Add Electricity Duty & PPAC
Electricity Duty = 5% × gross energy charges (before subsidy). PPAC (Power Purchase Adjustment Cost) is a monthly-revised surcharge on energy charges, typically 7–18% depending on your DISCOM — check your latest bill for the exact current rate.
Add Fixed Charge & Meter Rent
Add the Fixed/Demand Charge (based on your sanctioned load, typically ₹20–₹250/month) and Meter Rent (₹15–₹40/month). These apply regardless of the subsidy, since the subsidy only offsets energy charges.
Sum Up the Total
Total Bill = Energy Charges − Subsidy + Electricity Duty + PPAC + Fixed Charge + Meter Rent. Verify against your official BSES or Tata Power-DDL bill — use our calculator above for an instant, editable estimate.
Delhi Electricity Bill Examples for Common Usage Levels
See exactly how much you'd pay at different consumption levels — with and without the Delhi Govt subsidy — based on DERC's 2026 tariff order.
| Units/Month | Gross Energy Charge | Delhi Govt Subsidy | Duty + PPAC + Fixed/Meter* | Estimated Total (subsidised) |
|---|---|---|---|---|
| 100 units | ₹300 | −₹300 (100%) | ≈₹65 | ≈ ₹65 |
| 200 units | ₹600 | −₹600 (100%) | ≈₹95 | ≈ ₹95 |
| 300 units | ₹1,050 | −₹825 (50% on 201–400) | ≈₹150 | ≈ ₹375 |
| 400 units | ₹1,500 | −₹1,000 (capped ~₹800+free slab) | ≈₹200 | ≈ ₹700 |
| 500 units | ₹2,150 | None (over 400) | ≈₹390 | ≈ ₹2,540 |
| 800 units | ₹4,100 | None (over 400) | ≈₹720 | ≈ ₹4,820 |
*Duty (5%), PPAC (≈8% average across DISCOMs) and Fixed/Meter charges combined; figures are illustrative estimates — use the calculator above with your exact DISCOM for a precise figure.
Advantages & Disadvantages of Delhi's Subsidised Slab System
Delhi's electricity pricing is among the most consumer-friendly in India for low-to-moderate users, but the subsidy cliff and rising PPAC create real trade-offs worth understanding.
✅ Advantages
- Free power for consumption up to 200 units/month — near-zero bills for small households
- 50% subsidy on 201–400 units, capped at ₹800, softens mid-range bills
- Base tariff hasn't been revised since 2014, giving long-term predictability on slab rates
- Three competing DISCOMs plus strong DERC oversight has driven reliability and AT&C loss improvements since privatisation
- Widespread smart meter rollout makes usage tracking and staying within the free slab easier
⚠️ Disadvantages
- Crossing 400 units removes the ENTIRE subsidy, not just the excess — a steep "cliff" effect
- PPAC now moves monthly (since June 2026) and has climbed 16–18% for some DISCOMs, hitting high-consumption and commercial users hardest
- Subsidy requires an active opt-in — consumers who never opted in pay full tariff even under 200 units
- Summer AC-heavy households routinely exceed 400 units, losing the subsidy exactly when bills are highest
- Commercial and industrial consumers get no subsidy cushion at all, facing the full brunt of tariff and PPAC increases
20 Proven Ways to Reduce Your Electricity Bill in Delhi
Practical, Delhi-specific tips to stay within the free/subsidised slabs and cut your BRPL, BYPL or TPDDL bill.
Stay At or Below 400 Units — Delhi's Most Important Tip
Because losing the subsidy above 400 units removes it entirely (not just on the excess), tracking your meter in the last week of the billing cycle and trimming usage to stay at or under 400 units can save well over ₹1,500 in a heavy month.
Opt In to the Subsidy If You Haven't
The Delhi Govt subsidy isn't automatic — you must opt in via WhatsApp, missed call, your bill's QR code, or your DISCOM's office/app. It's a one-time registration that covers all future bills until you opt out.
Switch to 5-Star Appliances
A 5-star AC uses up to 25–30% less electricity than a 2-star equivalent. BEE star ratings ensure you know the real consumption. When replacing old appliances, always check the energy label.
Replace All Bulbs with LED
LEDs use just 8–10 watts versus 40–60 watts for incandescent bulbs. Replacing 10 bulbs in your home with LEDs can save roughly 300–400 units annually — often the difference between staying in the free slab or not.
Go Solar — Delhi's Growing Rooftop Opportunity
Under the Delhi Solar Policy and PM Surya Ghar Yojana, rooftop solar with net metering can offset a large share of your summer consumption. With PPAC now rising monthly, a well-sized system pays back faster than ever. Subsidy up to ₹78,000 for a 3kW system is available.
Install Roof Insulation
Delhi's flat concrete rooftops absorb intense heat in summer. Adding a false ceiling with rock wool or foam insulation can reduce indoor temperatures by 3–5°C, cutting AC or cooler usage significantly.
Shift Heavy Appliances to Night
Run washing machines, geysers, and dishwashers in the evening or night (after 10 pm). It reduces simultaneous load in your home and helps flatten your consumption curve.
Stop Phantom Load (Standby Power)
TVs, set-top boxes, chargers, and microwaves left plugged in keep drawing power even when idle. In a typical Delhi home, standby power wastes 50–100 units per year. Use switchable power strips.
Set AC at 24°C, Not 18°C
Every 1°C increase in AC temperature setting saves roughly 6% electricity. Setting your AC at 24°C instead of 18°C can save 30–40% on cooling costs — BEE recommends 24°C as the national standard.
Use Reflective Window Film
Delhi's west-facing windows bring in intense heat during summer afternoons. Metallic reflective films cut solar heat gain by 70–80%, keeping rooms cooler and reducing cooler or AC load.
Use Solar Water Heaters
Electric geysers are among the biggest electricity guzzlers in Delhi winters. A 100-litre solar water heater costs ₹15,000–₹25,000 but saves 200–400 units annually, paying for itself in 3–4 years.
Optimise Cooler Usage
Keep your air cooler's pads moist and clean — dirty pads reduce cooling by 30%. Use coolers instead of ACs on drier days (typical of Delhi's pre-monsoon months) for a fraction of the power draw.
Track Usage on the BSES / TPDDL App
Delhi's smart-meter rollout means most BRPL, BYPL and TPDDL consumers can see near real-time consumption on the DISCOM's app. Check weekly, not just when the bill arrives — a spike often means a faulty appliance or a geyser left on.
Service Your AC Every Summer
A dirty AC filter or low refrigerant can increase power draw by 20–30% for the same cooling. Get your AC serviced before peak summer to keep it running at rated efficiency.
Use Curtains & Cross-Ventilation
Thick curtains on sun-facing windows and cross-ventilation at night (once temperatures drop) reduce the hours your AC or cooler needs to run each day.
Fix Voltage Fluctuations
A stabiliser protects appliances from Delhi's occasional voltage swings, extends compressor life on ACs and refrigerators by 3–5 years, and avoids the hidden energy waste of a struggling motor.
Run a Family Savings Challenge
Make staying under 200 units a friendly household goal each month — a fun, effective way to build habits like switching off unused lights and fans.
Plant Shade Near West-Facing Walls
Trees or vertical gardens on the west side of your home block direct afternoon sun, measurably lowering indoor temperature and AC load in summer.
Use Timer Plugs for Water Pumps
Many Delhi homes run overhead-tank water pumps longer than necessary. A timer plug ensures the pump runs only as long as needed, avoiding wasted motor-running hours.
Review Your Sanctioned Load
If your sanctioned load is much higher than your actual peak usage, you may be paying more Fixed/Demand Charge than necessary. Ask your DISCOM to review and right-size it.
Delhi Electricity Bill: Everything You Need to Know in 2026
Delhi's power distribution has been in private hands since the 2002 privatisation, when the erstwhile Delhi Vidyut Board was split into three distribution companies. Today, BSES Rajdhani Power Limited (BRPL) and BSES Yamuna Power Limited (BYPL) — both part of the BSES group — along with Tata Power Delhi Distribution Limited (TPDDL), supply power across the National Capital Territory, with NDMC and Delhi Cantonment Board handling their own small jurisdictions. All three main DISCOMs operate under a single tariff order issued by the Delhi Electricity Regulatory Commission (DERC).
Understanding DERC and How Tariffs Are Set
DERC is the state regulator that approves all electricity tariffs in Delhi. Each DISCOM submits an Annual Revenue Requirement (ARR) petition justifying its cost structure and any proposed rate changes; DERC holds public hearings before issuing its tariff order. Delhi's base domestic slab structure has stayed unchanged since 2014/FY2021-22 — a rare case of long-term rate stability in India — with only the PPAC (Power Purchase Adjustment Cost) component moving between orders.
PPAC reflects the gap between what DISCOMs actually pay to buy power and what was assumed in the base tariff. In June 2026, DERC shifted PPAC review from quarterly to monthly, and the newly sanctioned surcharges — roughly 17.9% for BRPL, 17.4% for BYPL and 16.0% for TPDDL — are among the highest in years. Subsidised households under 400 units are largely shielded from this, since the subsidy is calculated on energy charges regardless of PPAC movements, but high-consumption and commercial users feel the increase directly.
Why Delhi Bills Spike in April–June
Delhi's summer regularly pushes household consumption well above 400 units/month once air conditioners run for extended hours. A single 1.5-ton AC running 8 hours a day can consume close to 300–350 units a month on its own. Add lighting, refrigerator, TV, and water pump — and many households in Dwarka, Rohini, or Karol Bagh cross the 400-unit subsidy threshold in peak months, losing the entire subsidy and landing on the full ₹6.50–₹8.00/unit slabs plus a higher PPAC surcharge. This is exactly why monitoring usage and shifting to more efficient cooling makes such a large financial difference in Delhi specifically.
The Delhi Free Electricity & Subsidy Scheme
Unlike states that offer free power to specific categories only, Delhi runs a near-universal domestic subsidy: consumers using up to 200 units/month pay nothing for energy charges, and those using 201–400 units/month get a 50% discount on energy charges, capped at ₹800/month. This is not automatic — households must opt in once, via WhatsApp ("Hi" to the DISCOM's registered number), a missed call, the QR code on their bill, or their DISCOM's office. Fixed/demand charges, meter rent, duty and PPAC still apply even within the free slab, since the subsidy only offsets energy charges.
How to Check Your Delhi Electricity Bill Online
BRPL and BYPL consumers can view and pay bills at bsesdelhi.com (or the BSES app), while TPDDL consumers use tatapower-ddl.com (or the Tata Power-DDL app). You'll need your Customer Account (CA) Number printed on your current bill. You can also pay via BHIM, PhonePe, Google Pay, Paytm, or Bharat Bill Pay under "Electricity Bills."
Net Metering for Solar Users in Delhi
Under the Delhi Solar Policy, consumers who install rooftop solar can export surplus electricity back to the grid and receive credit through net metering, adjusted directly on their BSES or Tata Power-DDL bill. Businesses without suitable roof space can also participate via Virtual Net Metering (VNM) or Group Net Metering, subscribing to solar capacity located elsewhere. Combined with the PM Surya Ghar central subsidy, this makes rooftop and community solar one of the fastest-payback investments for Delhi households and businesses facing rising PPAC charges.

Delhi Electricity Bill Calculator – How It Works
Everything you need to know — from inputs to slab math to final bill
About the Calculator
This tool calculates your Delhi electricity bill using the official DERC (Delhi Electricity Regulatory Commission) tariff slabs for 2025–26. It covers all three main distribution companies — BRPL, BYPL and TPDDL — which follow an identical base tariff structure, differing only in PPAC.
Unlike generic calculators, every charge component is computed separately: energy charges slab-by-slab, the Delhi Govt subsidy applied where eligible, electricity duty on gross energy, PPAC as a DISCOM-specific surcharge, and flat fixed/meter charges. This matches how BSES and Tata Power-DDL bills are actually generated.
- Telescopic slab billing — each unit priced at its own slab rate
- Built-in Delhi Govt subsidy toggle (0–200 free, 50% off 201–400)
- Covers domestic and commercial connection types
- Editable slab rates — test custom tariff scenarios
- Visual charts for slab cost breakdown and multi-unit comparison
- Works offline after first load — no server calls during calculation
Why DERC Tariff, Not Estimated Rates
Many online calculators use rounded or outdated per-unit figures. This calculator sources slabs directly from DERC's tariff order: ₹3.00, ₹4.50, ₹6.50, and ₹8.00 per unit across four domestic slabs, verified against BRPL, BYPL and TPDDL billing documentation.
PPAC (currently ≈7–18% depending on DISCOM, revised monthly since June 2026) and Electricity Duty (5% of energy charges) are applied separately, as they appear on your actual bill. This gives you an estimate accurate to within a small margin of your real bill — far more precise than flat per-unit calculators.

How to Use the Delhi Electricity Bill Calculator
What Are Slabs in Electricity Billing?
Electricity slabs are consumption ranges, each with a fixed per-unit rate. Delhi uses a telescopic slab system — meaning each slab rate applies only to units within that range. Your total consumption is never multiplied by a single rate.
This system protects low-income households: a family using 150 units stays entirely in the ₹3.00 slab, and with the subsidy, pays nothing for energy. A household using 500 units pays ₹3.00 for the first 200, ₹4.50 for the next 200, and ₹6.50 for the remaining 100 — not ₹6.50 across all 500 units.
The financial implication of the subsidy, however, is different from the slabs themselves — crossing 400 units doesn't just add the next slab's rate, it removes the subsidy on everything. This is why staying near the 200 and 400-unit thresholds matters so much for your bill.

Delhi Electricity Bill — Answered in Seconds
Direct answers to the most searched questions about Delhi electricity tariff, BRPL, BYPL, TPDDL, and bijli billing. Includes Delhi's subsidy scheme explained clearly.
As of 2026, Delhi domestic tariff (BRPL / BYPL / TPDDL) has 4 telescopic slabs:
| Consumption | Rate (₹/unit) |
|---|---|
| 0 – 200 units | ₹3.00 (free with subsidy) |
| 201 – 400 units | ₹4.50 |
| 401 – 800 units | ₹6.50 |
| Above 800 units | ₹8.00 |
Source: DERC Tariff Order FY 2025–26. ⚡ Telescopic — each slab rate applies only to units within that range.
Formula: Total Bill = Energy Charges − Delhi Govt Subsidy + Electricity Duty (5% of energy) + PPAC (≈7–18%) + Fixed Charge + Meter Rent
▸ Energy = 200 × ₹3.00 = ₹600 (telescopic)
▸ Subsidy = −₹600 (100% free)
▸ Duty ≈ ₹30 | PPAC ≈ ₹48
▸ Fixed + Meter ≈ ₹40
▸ Total ≈ ₹95–₹120
PPAC = Power Purchase Adjustment Cost. A surcharge that lets BRPL, BYPL and TPDDL recover fluctuations in what they actually pay to buy power, on top of the base tariff. Since June 2026, DERC reviews it monthly instead of quarterly — currently roughly 17.9% (BRPL), 17.4% (BYPL), 16.0% (TPDDL) of energy charges, the highest levels in years.
Electricity Duty = 5% of energy charges (domestic) — not GST, and calculated on gross energy charges before the subsidy is deducted. Collected by BRPL/BYPL/TPDDL on behalf of the Delhi government.

Delhi Electricity Consumer Rights & How to File a Complaint
Under the Electricity Act 2003 and DERC regulations, Delhi electricity consumers have legally enforceable rights. If your bijli bill seems wrong — especially regarding subsidy application or PPAC charges — you have a clear escalation path.
Step 1: Contact Your DISCOM
Call the BRPL/BYPL helpline 19123 or the TPDDL helpline, or visit your local DISCOM office. BSES has a portal at bsesdelhi.com and Tata Power-DDL at tatapower-ddl.com. They are required to respond within a defined period under DERC Consumer Grievance norms.
Step 2: Consumer Grievance Forum
If DISCOM resolution is unsatisfactory, escalate to the DISCOM's Consumer Grievance Redressal Forum (CGRF), mandated under Electricity Act 2003. BRPL, BYPL and TPDDL each maintain their own CGRF. File online or in person.
Step 3: DERC Ombudsman
If CGRF fails, escalate to the DERC-appointed Electricity Ombudsman. File a petition at derc.gov.in. The Ombudsman can order bill corrections, refunds, and penalties — especially useful for subsidy or PPAC disputes.
Your Key Rights as a Delhi Electricity Consumer
Solar Rooftop & Net Metering in Delhi — Complete 2026 Guide
Delhi gets strong year-round sun despite its haze — around 5.0 kWh/m²/day on average. With PPAC now rising monthly and the subsidy cliff at 400 units, a well-sized rooftop or community solar system can meaningfully cut both energy charges and PPAC exposure. PM Surya Ghar subsidy up to ₹78,000 is available.
How Net Metering Works in Delhi
When your rooftop solar system produces more electricity than you consume, the surplus units are exported to the grid. These exported units are credited to your bill at the DERC-notified rate through net metering. Your monthly bill = Units drawn from grid × tariff rate minus export credit.
Under the Delhi Solar Policy, both individual net metering and Virtual/Group Net Metering (VNM/GNM) are available — the latter lets flat owners, tenants, or businesses without roof access subscribe to solar capacity installed elsewhere and still get bill credit. BRPL, BYPL and TPDDL all process net metering applications through their respective portals.

Delhi Electricity Tariff Revision History (2014–2026)
DERC revises tariffs through its Annual Tariff Order process. Unlike many states, Delhi's base domestic slab rates have stayed remarkably stable since 2014 — here's how the structure, subsidy, and PPAC have evolved.
Smart Meters & Prepaid Electricity in Delhi — What You Need to Know
Under the Revamped Distribution Sector Scheme (RDSS), Delhi has one of India's most advanced smart meter rollouts across BRPL, BYPL and TPDDL territories. Here's how it changes your bijli billing.
📟 What is a Smart Prepaid Meter?
A smart prepaid meter works like a mobile recharge — you top up before you consume. When your balance runs low, you receive an SMS or app alert. No more bill shock, no due dates to remember, and no disconnection surprises.
The same DERC-approved tariff slabs and Delhi Govt subsidy apply to prepaid meters — no separate "prepaid rate." Your free/subsidised units are still credited automatically. Billing shifts from monthly to near real-time, and you can track consumption daily via the BSES or Tata Power-DDL app.
Benefits of Smart Meters for Consumers
- Daily or hourly consumption visibility via app
- No estimated billing — only actual readings
- Instant low-balance SMS alerts
- Eliminates meter reading visits
- Faster fault detection by your DISCOM
📍 Rollout Status in Delhi (2026)
BRPL, BYPL and TPDDL have all completed the bulk of their smart meter rollout across Delhi NCT under RDSS central funding — among the most advanced in India. Check your app or call your DISCOM's helpline to confirm your connection's smart-meter status.
BRPL vs BYPL vs TPDDL — Which DISCOM Is Cheaper?
All three DISCOMs follow the same DERC base tariff and subsidy scheme — the only real difference in your bill comes from PPAC, which is reviewed and set separately for each.
| Feature | BRPL | BYPL | TPDDL |
|---|---|---|---|
| Area Served | South & West Delhi | Central & East Delhi | North & North-West Delhi |
| Base Tariff (Domestic) | DERC standard (₹3.00–₹8.00) | DERC standard (₹3.00–₹8.00) | DERC standard (₹3.00–₹8.00) |
| Current PPAC (approx.) | ≈17.9% | ≈17.4% | ≈16.0% |
| Delhi Govt Subsidy | Applies (opt-in) | Applies (opt-in) | Applies (opt-in) |
| Smart Meter Rollout | Largely complete | Largely complete | Among India's most advanced |

Surprising Delhi Electricity Facts (That Affect Your Bill)
These statistics explain why Delhi consumers face unique billing patterns — especially around the subsidy cliff and summer PPAC hikes — and why solar has growing appeal here.
🔥 Shareable Fact: The Delhi Subsidy Cliff Effect
A Delhi household using 400 units in July (subsidised) pays approximately ₹700–₹900. The very same household crossing to 410 units loses the entire subsidy and pays roughly ₹2,200+ — more than double the bill for just 10 extra units. This "cliff" makes staying under 400 units in peak summer months one of the highest-value habits a Delhi household can build.

All tariff data is sourced directly from the Delhi Electricity Regulatory Commission (DERC) Annual Tariff Orders and official BSES/Tata Power-DDL documentation.
The current base rates (₹3.00 – ₹8.00/unit for domestic consumers) are from the DERC Tariff Order for Financial Year 2025–26, applicable to all three distribution companies: BRPL, BYPL and TPDDL. PPAC figures (≈16–18%) are verified against each DISCOM's monthly PPAC notification as of June 2026.
