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.

How the BESCOM bill is calculated

Your bill, component by component

Based on the 250-unit example above. Expand each line for what it means and whether you can influence it.

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 BESCOM compare?

BESCOM's top domestic slab rate is ₹8.60/unit — more expensive than TNEB (₹11.55/unit), — cheaper than KSEB (₹8.50/unit), — more expensive than APSPDCL (₹9.75/unit). Billing cycles also differ: BESCOM bills monthly, while TNEB bills bi-monthly, KSEB bills bi-monthly, APSPDCL bills monthly.

Tips to reduce your BESCOM bill

• Where practical, keep usage below your next slab threshold — the marginal units above ₹8.60/unit cost the most.
• The ₹0.36/unit fuel cost adjustment applies to every unit you use, so reducing overall consumption reduces this line too — unlike the fixed charge.
• For high-usage households, rooftop solar can offset your most expensive top-slab units — see the solar section above.

Energy saving tips for Karnataka 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 BESCOM

• 2002 — BESCOM (Bangalore Electricity Supply Company Ltd) formed 1 June 2002, when the Karnataka Power Transmission Corporation Ltd (KPTCL)'s distribution business split into five regional companies — BESCOM, MESCOM, HESCOM, GESCOM and CESC — while KPTCL retained transmission.
• Coverage — BESCOM's territory covers Bangalore Urban and Bangalore Rural districts plus six neighbouring districts (Chikkaballapura, Kolar, Davanagere, Tumkur, Chitradurga, Ramanagara) — wider than Bangalore city alone.

Does BESCOM supply all of Bangalore city?

Yes for Bangalore itself, but BESCOM's territory extends well beyond the city — it covers eight districts in total. If your connection is outside Bangalore Urban/Rural (for example in Mangalore, Hubli or Gulbarga), you're more likely served by MESCOM, HESCOM or GESCOM instead.
