Frequently Asked Questions
Common queries answered for you
Electricity companies use a progressive slab system. For example, if you consume 250 units and the first slab is 100 units, those 100 units are charged at a lower rate, and the remaining 150 are charged at the next higher rate.
Fixed charges are the base cost of maintaining the connection and infrastructure, usually calculated based on your sanctioned load (kW).
Reducing consumption to stay within lower slabs is the most effective way. Switching to LED bulbs, using 5-star ACs, and taking advantage of solar energy can significantly lower your costs.
What is How to Calculate Your Electricity Bill??
Indian electricity bills are calculated using a cumulative slab system. This means the first few units are cheap, and as you consume more, the rate per unit increases significantly.
📊 Practical Example
"In Maharashtra, if you use 150 units, the first 100 units are charged at ~₹4.41, and the next 50 units at ~₹9.64. This jump makes the second half of your consumption much more expensive."
⚠️ Common Mistake
Ignoring the 'Sanctioned Load'. If you have a high load (e.g. 5kW) but low usage, your 'Fixed Charges' will remain high. Always ensure your load matches your actual appliance needs.
