West Bengal's Hasir Alo lifeline scheme — built into this calculator
Hasir Alo is a lifeline scheme: up to 75 units per quarter (≈25 units/month) are free for small 0.3 kW connections. It only touches tiny-consumption homes, and this calculator shows the waiver precisely when it applies — most homes bill under the normal 102-unit block tariff.
West Bengal bill — quick answers
Why do WB bills look confusing with 102-unit bands?
WBSEDCL's order structures slabs around 102-unit blocks (a legacy of average billing). Our table lists the exact bands — your bill should match line-by-line.
CESC vs WBSEDCL — which is cheaper?
CESC's licensed areas use their own tariff (₹4.92 base) with a separate FAC. Compare your last 6 bills; meter mode in this tool makes that exact.
Does West Bengal have a free-units scheme?
Hasir Alo: lifeline connections (≤0.3 kW) get up to 75 units per quarter (≈25 units/month) free. It only touches tiny-consumption homes — the calculator shows the waiver when it applies.

West Bengal electricity bill calculator — how your bijli bill is built
West Bengal's power is split between WBSEDCL, which covers the districts, and CESC, the Kolkata licensee. Both bill on a monthly ladder (the state's quarterly 102/78/120/300/300+ units ÷3): ₹5.04 for the first 34 units, then ₹6.33, ₹7.12, ₹7.52, ₹7.69 and ₹9.22 beyond, with a ₹30/kVA fixed charge, ₹10 meter rent and ₹0.23/unit FAC. CESC's Kolkata schedule runs close behind.
West Bengal bills by the quarter, so divide a paper-bill reading by three to get the monthly figure the calculator expects — the slab boundaries are already scaled down.
Example: your West Bengal bill for 250 units
Take a West Bengal household using 250 units in one month on WBSEDCL. The telescopic energy charge is 34 × ₹5.04 + 26 × ₹6.33 + 40 × ₹7.12 + 100 × ₹7.52 + 50 × ₹7.69 = ₹1757.24. Add the fixed charge (₹60.00), FAC (₹57.50) — that gives a gross bill of ₹1884.74. With no subsidy in this state, ₹1884.74 is your payable.
Here is the same 250 units across every DISCOM in West Bengal — useful when your board's name differs from the common one:
| DISCOM | Energy | Fixed | FAC | Duty | Subsidy | Total |
|---|---|---|---|---|---|---|
| WBSEDCL | ₹1757.24 | ₹60.00 | ₹57.50 | ₹0.00 | — | ₹1884.74 |
| CESC (Kolkata) | ₹1706.88 | ₹60.00 | ₹57.50 | ₹0.00 | — | ₹1834.38 |
West Bengal subsidy / free-unit scheme
West Bengal's Hasir Alo scheme gives lifeline connections (sanctioned load ≤0.3 kW) up to 75 units free per quarter (≈25 units/month) — the whole bill is waived by subsidy. The calculator models it as a 25-unit monthly zero bill for that connection class.
West Bengal tariff details — live data
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 |
|---|---|---|---|
| WBSEDCL | 1–34 @ ₹5.04, 35–60 @ ₹6.33, 61–100 @ ₹7.12, 101–200 @ ₹7.52, 201–300 @ ₹7.69, 301–above 301 @ ₹9.22 | ₹30/kW load | ₹0.23/unit |
| CESC (Kolkata) | 1–34 @ ₹4.92, 35–60 @ ₹6.1, 61–100 @ ₹6.9, 101–200 @ ₹7.3, 201–300 @ ₹7.5, 301–above 301 @ ₹8.9 | ₹30/kW load | ₹0.23/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.
4 practical ways to lower your West Bengal bill
- The step from the first slab (₹5.04) to the next (₹6.33) is small — keeping the whole bill below 100 units avoids the ₹7.12+ bands.
- Kolkata's humidity makes AC a year-round load; 26°C with a fan saves units.
- CESC and WBSEDCL rates differ slightly — the board chips show both side by side.
- A solar plant works well in the Howrah–Hooghly belt with net-metering; see the solar tool.
Quick questions about West Bengal bills
Which utility serves my address?
CESC for Kolkata municipal limits; WBSEDCL for all districts including Howrah, Bardhaman and North 24 Parganas outside Kolkata.
Why does the slab boundary sit at 34 units?
The WBERC order sets the first band at 0–34 units/month (0–102 per quarterly bill); the calculator uses the monthly conversion, so the boundaries you see are 34/60/100/200/300.
Is there a free-unit scheme?
Lifeline consumers with ≤0.3 kW sanctioned load get up to 75 units free per quarter under Hasir Alo; other domestic consumers bill at the normal tariff.
What is the fixed charge?
₹30/kVA of sanctioned load per month, plus a ₹10 meter rent — the calculator shows both as item lines.
