How to Read Your CESC Kolkata Meter & Avoid Higher Tariff Slabs
Follow these 3 practical steps to determine your exact monthly consumption from your digital energy meter and manage high-draw appliances:
Wait for the auto-scroll display on your digital energy meter until the cumulative reading ending with kWh appears.
Subtract the previous month's final reading from your current reading:
Units = Current kWh - Previous kWh
Enter the resulting units into our CESC Kolkata calculator above to see your exact breakdown of energy charges, load fees, duty, and subsidies.
Target High-Draw Appliances to Avoid Upper Slab Tiers
Every degree increase above 18°C reduces AC power draw by approx 6%. Setting your 1.5 Ton AC to 24°C can save significant kWh monthly.
Replacing standard 75W induction fans with 28W BLDC fans reduces fan energy use by ~60%, lowering your monthly slab progression.
Under PM Surya Ghar Muft Bijli Yojana, a 2 kW to 3 kW rooftop solar system generates approx 240-360 units monthly with central subsidies.
Track daily peak consumption and shift heavy appliances (water heaters, washing machines) to avoid unexpected slab tier jumps.
