Frequently Asked Questions
How do I read my electricity meter?+
Your electricity bill shows the opening and closing meter reading for the billing period. Units consumed = closing reading − opening reading. One unit = 1 kWh (kilowatt-hour) = energy used by a 1000-watt appliance for 1 hour.
Why is my electricity bill higher in summer?+
Air conditioning is the biggest driver — a 1.5-ton AC running at 1.5 kW for 8 hours/day consumes 360 kWh/month, which can double your bill. Other summer factors: fans running longer, fridges working harder, and higher base tariff slabs if you cross usage thresholds.
How can I reduce my electricity bill?+
