Electricity bill for 150 units in India

For 150 units of monthly domestic consumption (3 kW sanctioned load, no subsidy), the bill ranges roughly from ₹204 (TNEB / TANGEDCO, Tamil Nadu) to ₹2,128 (JVVNL, Rajasthan) — a median of about ₹890 across India. Exact numbers depend on your DISCOM's slab rates, fixed charges, FAC and electricity duty.

Each State Electricity Regulatory Commission (SERC) sets its own slab structure, fixed charges, Fuel Adjustment Charge (FAC) and electricity duty. Subsidies also differ — e.g. Punjab, Delhi and Tamil Nadu offer up-to-200-unit free electricity schemes for eligible households. That's why a 150-unit bill in Mumbai can be very different from 150 units in Chennai or Lucknow.

At 150 units/month, the biggest wins usually come from: (1) swapping conventional fans to BLDC (save 15–25 units/mo per fan), (2) moving to 5-star inverter AC if you have one, (3) replacing geyser with a heat-pump or 5-star model, (4) evaluating rooftop solar under PM Surya Ghar Muft Bijli Yojana — 150-unit consumers often see 3–6 year payback.
