Delhi's 200-unit zero bill & 50% subsidy — built into this calculator
Delhi's scheme works in two layers: use up to 200 units and your bill is ₹0 (zero bill), and 201–400 units get 50% off the energy charge capped at ₹800/month. This calculator applies both layers automatically — untick "Apply state subsidy" to see the full DERC tariff without the scheme, and compare exactly how much the subsidy is saving you.
Delhi bill — quick answers
How does Delhi's 200-unit zero bill and 50% subsidy work?
Use up to 200 units and the whole bill is ₹0 (zero bill). From 201–400 units you pay 50% of the energy charge, capped at ₹800/month; beyond 400 units there is no subsidy. The toggle reproduces both layers automatically.

Delhi electricity bill calculator — how your bijli bill is built
Delhi is served by four utilities — BSES Rajdhani (BRPL, west and central), BSES Yamuna (BYPL, east), Tata Power-DDL (TPDDL, north and parts of west) and NDMC (the New Delhi municipal area). All four bill on DERC-approved telescopic slabs of ₹3.00, ₹4.50, ₹6.50, ₹7.00 and ₹8.00 per unit, plus a ₹20/kW monthly fixed charge, a ₹0.30/unit FAC proxy, no electricity duty and the monthly FPPAS surcharge on top — BRPL 25.00%, BYPL 19.91% and TPDDL 12.21% under the DERC order of 10 July 2026 (May-2026 cycle).
Because the fixed charge is a small ₹20/kW and duty is zero, a Delhi bill's outcome rests almost entirely on units and the 200-unit subsidy. Enter your reading and the slab bars will highlight exactly where your consumption sits — under 200 units (and opted in), your bill is exactly ₹0.
Example: your Delhi bill for 250 units
Take a Delhi household using 250 units in one month on BSES Rajdhani (BRPL). The telescopic energy charge is 200 × ₹3 + 50 × ₹4.5 = ₹825.00. Add the fixed charge (₹20.00), FAC (₹75.00) — that gives a gross bill of ₹920.00. The state subsidy of ₹460.00 is then deducted, leaving ₹460.00 payable.
Here is the same 250 units across every DISCOM in Delhi — useful when your board's name differs from the common one:
| DISCOM | Energy | Fixed | FAC | Duty | Subsidy | Total |
|---|---|---|---|---|---|---|
| BSES Rajdhani (BRPL) | ₹825.00 | ₹20.00 | ₹75.00 | ₹0.00 | −₹460.00 | ₹460.00 |
| BSES Yamuna (BYPL) | ₹825.00 | ₹20.00 | ₹75.00 | ₹0.00 | −₹460.00 | ₹460.00 |
| Tata Power-DDL (TPDDL) | ₹825.00 | ₹20.00 | ₹75.00 | ₹0.00 | −₹460.00 | ₹460.00 |
| NDMC (New Delhi) | ₹990.00 | ₹25.00 | ₹25.00 | ₹0.00 | −₹520.00 | ₹520.00 |
Delhi subsidy / free-unit scheme
Delhi's flagship subsidy (opt-in, renewed each financial year) makes the entire bill ₹0 up to 200 units, and gives a 50% discount on the 201–400 unit band, capped at ₹800/month. Above 400 units the subsidy is removed entirely and the full slab ladder applies — one unit past 400 can cost hundreds of extra rupees. The calculator applies both tiers automatically and shows them as a green itemised line.

The table below is generated from the same data the calculator uses, so what you see here is exactly what is charged. Looking for the per-unit electricity price in The slab column IS your per-unit rate — each rate applies only to the units inside its own slab range.
| DISCOM | Slabs | Fixed charge | FAC |
|---|---|---|---|
| BSES Rajdhani (BRPL) | 1–200 @ ₹3, 201–400 @ ₹4.5, 401–800 @ ₹6.5, 801–1200 @ ₹7, 1201–above 1201 @ ₹8 | ₹20/month | ₹0.3/unit |
| BSES Yamuna (BYPL) | 1–200 @ ₹3, 201–400 @ ₹4.5, 401–800 @ ₹6.5, 801–1200 @ ₹7, 1201–above 1201 @ ₹8 | ₹20/month | ₹0.3/unit |
| Tata Power-DDL (TPDDL) | 1–200 @ ₹3, 201–400 @ ₹4.5, 401–800 @ ₹6.5, 801–1200 @ ₹7, 1201–above 1201 @ ₹8 | ₹20/month | ₹0.3/unit |
| NDMC (New Delhi) | 1–200 @ ₹3.6, 201–400 @ ₹5.4, 401–above 401 @ ₹6.5 | ₹25/month | ₹0.1/unit |
Remember: in telescopic billing each slab rate applies only to the units inside its range. Many websites multiply one rate by total units — that is wrong and overstates bills. This calculator, like your DISCOM, adds slab by slab.
5 practical ways to lower your Delhi bill
- Run the AC at 24–26°C — the summer AC is the first thing that pushes Delhi homes past the 200-unit line.
- Heat the geyser only in the morning; a 2-hour daily geyser adds roughly ₹300 a month at these slab rates.
- Replace your three oldest fans with BLDC 5-star fans — half the power, same airflow.
- Stay under 200 units to ride the ₹0 bill — the meter-reading mode makes it easy to track.
- Compare BRPL, BYPL, TPDDL and NDMC in one click — the slabs match, so service perks decide.
Quick questions about Delhi bills
How does Delhi's subsidy work?
Opt in and consume up to 200 units and the whole bill — energy, fixed charge and FAC — is waived to ₹0. From 201 to 400 units you get a 50% discount on that band, capped at ₹800/month. Above 400 units the subsidy is removed and full slab rates apply.
Which DISCOM am I under?
Check your bill's logo: BRPL (west/central), BYPL (east), Tata Power-DDL (north/west) or NDMC (New Delhi area). Our dropdown lists all four.
Why does my bill keep a FAC/FPPAS line?
FAC is approximated here at ₹0.30/unit; the real fuel-and-power-purchase surcharge (FPPAS) is a percentage — BRPL 25.00%, BYPL 19.91%, TPDDL 12.21% for May 2026 under the DERC order of 10 July 2026 — and changes every month. It is the moving part of your bill besides units.
Is the ₹800 cap per meter?
The cap applies per domestic connection per month; the calculator caps automatically so the estimate never exceeds the scheme limit.
