Understanding WBSEDCL Domestic Quarterly Slabs

In West Bengal, domestic consumers under WBSEDCL receive electricity bills every three months (quarterly cycle). Because the billing period is 90 days, the progressive tariff slabs approved by the West Bengal Electricity Regulatory Commission (WBERC) are scaled up three times:

Official WBSEDCL domestic quarterly tariff rate blocks
Telescopic Consumption BlockMonthly EquivalentApproved Base Rate (₹/kWh)Application
0 to 102 unitsUp to 34 units / month₹5.30Lifeline baseline energy rate
103 to 180 units (next 78 units)35 to 60 units / month₹5.97Moderate household tier
181 to 300 units (next 120 units)61 to 100 units / month₹6.97Standard urban/semi-urban tier
301 to 600 units (next 300 units)101 to 200 units / month₹7.31Heavy usage (e.g. AC / Pump)
601 to 900 units201 to 300 units / month₹8.59Multi-AC / high consumption
Above 900 unitsOver 300 units / month₹8.99Highest slab rate

What Number to Write in the Load Enhancement Form:
When applying for an increase in load at your local WBSEDCL Customer Care Centre (CCC), write the Contract Demand in kVA (computed from your connected kW divided by 0.85 power factor). If your contract demand exceeds 5 kW (5.88 kVA), you must request a conversion to a Three-Phase meter.

Frequently Asked Questions (সচরাচর জিজ্ঞাস্য প্রশ্ন)

How does WBSEDCL telescopic quarterly billing work for domestic consumers?

WBSEDCL divides quarterly domestic consumption into telescopic progressive slabs: the first 102 units are billed at ₹5.30/unit; the next 78 units (103–180) at ₹5.97/unit; the next 120 units (181–300) at ₹6.97/unit; the next 300 units (301–600) at ₹7.31/unit; the next 300 units (601–900) at ₹8.59/unit; and any consumption above 900 units at ₹8.99/unit. Consumers only pay higher slab rates for the units exceeding the previous tier, rather than on their entire bill.

What is the prompt payment rebate on a WBSEDCL electricity bill?

WBSEDCL grants a 1% prompt payment rebate on the base Energy Charge (excluding fixed charges, meter rent, and government duty) if payment is deposited on or before the designated prompt payment date printed on your quarterly bill card.

When is a Three-Phase electricity connection mandatory in West Bengal?

Under West Bengal Electricity Regulatory Commission (WBERC) regulations, domestic supply up to 5 kW (or approx 5.88 kVA) is provided through a Single-Phase 230V connection. When your connected load or contract demand exceeds 5 kW (common when operating multiple air conditioners, water pumps, and geysers simultaneously), a Three-Phase 400V connection becomes legally mandatory.

What is the difference between Connected Load and Contract Demand (Sanctioned Load)?

Connected Load is the mathematical sum of the rated power wattage of all electrical equipment and appliances wired in your home. Contract Demand (Sanctioned Load) is the capacity agreed with WBSEDCL in kW or kVA taking into account a domestic diversity factor (~0.8), acknowledging that not all appliances run at maximum power simultaneously.

What should I do if my home appliance load exceeds my sanctioned meter capacity?

If you install high-wattage equipment like a 1.5-Ton AC or electric vehicle charger, submit an online or written Load Enhancement Application to your local WBSEDCL Customer Care Centre (CCC). Continuing to draw excessive power without enhancing load risks meter burnout and punitive low-power-factor or unauthorized-load charges.
