The quarterly rule

WBSEDCL bills quarterly. The units you enter represent your full ~90-day billing period — not a single month. To compare against a monthly figure, we divide the total by 3, shown as the monthly-equivalent on your result.

What are slabs in electricity billing?

Most Indian DISCOMs bill domestic electricity using telescopic slabs — tiered per-unit rates that rise as your consumption increases.

• Each slab has its own rate — for example the first 100 units might be billed at one rate and the next 100 at a higher one.
• Slabs are telescopic, not retroactive — only the units that fall inside a higher slab are billed at that slab's rate, not your entire consumption.
• The slab count resets every billing cycle — monthly, bimonthly or quarterly, depending on your DISCOM.
• Some DISCOMs add a fuel cost adjustment or electricity duty on top of the slab rate — see the tariff table above for what applies here.

What's included in your bill

How to read your meter

Digital meters show a running total in kWh ("units") on an LCD display — write down the number before the decimal point. To find your consumption for a billing period, subtract your previous reading from your current reading; that is exactly what the "Meter reading" mode in the calculator above does for you. Analog meters use a set of dial gauges read left to right — note the number the pointer has just passed on each dial.

How does WBSEDCL compare?

WBSEDCL's top domestic slab rate is ₹6.81/unit — more expensive than JBVNL (₹6.85/unit), — cheaper than TPCODL (₹6.10/unit), — more expensive than APDCL (₹7.60/unit). Billing cycles also differ: WBSEDCL bills quarterly, while JBVNL bills monthly, TPCODL bills monthly, APDCL bills monthly.

Tips to reduce your WBSEDCL bill

• Where practical, keep usage below your next slab threshold — the marginal units above ₹6.81/unit cost the most.
• For high-usage households, rooftop solar can offset your most expensive top-slab units — see the solar section above.

Energy saving tips for West Bengal electricity bills

Net metering explained

Net metering lets a rooftop solar system export surplus power back to the grid through your existing meter, which runs in reverse. At billing time, your DISCOM credits the exported units against what you drew from the grid — you're billed only for the net difference. Combined with telescopic slabs, this typically offsets your most expensive units first.

About WBSEDCL

• 1955 — West Bengal State Electricity Board (WBSEB) formed.
• 2007 — Unbundled 1 April 2007 under the state's Power Reform Scheme into West Bengal State Electricity Distribution Company Ltd (WBSEDCL) for distribution and West Bengal State Electricity Transmission Company Ltd (WBSETCL) for transmission.
• Coverage — WBSEDCL distributes power across most of West Bengal, but not Kolkata: the city, Howrah and parts of North/South 24 Parganas and Hooghly are served by CESC Limited, a separate private licensee with its own tariff.

Does WBSEDCL supply electricity to Kolkata?

No — Kolkata and its immediate surroundings (Howrah, and parts of North and South 24 Parganas and Hooghly) are served by CESC Limited, a separate private licensee. WBSEDCL covers the rest of West Bengal outside that area.
