Tips to reduce your bill
- - Switch to 5-star BEE-rated appliances - they use 30-50% less electricity
- - Use LED bulbs (7W LED = 60W incandescent in brightness)
- - Set AC to 24-26 degrees C - each degree below 24 increases consumption ~6%
- - Avoid peak hours (6-10 PM) if your DISCOM has time-of-use tariffs
- - A 1kW solar rooftop panel generates ~100-120 units/month in India
Includes the automatic state subsidy for your usage level. Estimate for a domestic connection. Fuel adjustment charges, electricity duty and other state levies change often and vary by state, so your actual bill can differ. Check your DISCOM website or latest electricity bill for exact rates.
