How BESCOM Calculates Your Bill — The Bangalore Slab Trap
ವಿದ್ಯುತ್ ಸ್ಲ್ಯಾಬ್ ಗಣನೆ (Electricity Slab Calculation)
BESCOM uses a progressive slab system — you pay the slab rate only for units within that band, not on your entire consumption. But the 186% jump from Slab 1 (₹2.85) to Slab 5 (₹8.16) means a single hot month can triple your bill.
Worked Example: 250 units in Bengaluru

Slab 3 — 120 units

May (peak summer)

June (monsoon)
₹2,007
Slab 4 — 280 units
AC at 5 hrs/day — still slab 4
The 401-Unit Trap
Once you cross 400 units, every additional unit costs ₹8.16. Running an extra hour of AC can cost ₹24.48 for that marginal hour alone.
Reading Delay Penalty
BESCOM meter reads can be delayed by 2–4 days. A delayed read in May can push summer + shoulder consumption into the same bill — causing artificial slab jumping.
Solar Net-Metering in Karnataka (BESCOM)
KERC net metering buy-back rate: ₹3.56/unit — India's joint-highest. PM Surya Ghar subsidy up to ₹78,000 applies.

Bengaluru Solar Advantage
Bengaluru receives ~5.5 peak sun hours/day — higher than Mumbai and Chennai. A Slab 4 consumer (300 units/month) can wipe out their entire bill with a 2kW system, converting ₹2,000+ monthly bills to near-zero.
