Electricity consumption is measured in kilowatt-hours (kWh), commonly referred to as 'units.' One unit equals the energy consumed by a 1,000-watt appliance running for one hour. Your electricity meter records total consumption, and your bill is calculated based on the tariff rates applicable to your consumption slab.

Electricity tariffs use a progressive slab structure where per-unit rates increase with consumption. This encourages energy conservation. Most state electricity boards have 4-5 slabs starting from a subsidized rate for low consumption (typically up to 100 units) to higher rates for consumption above 500 units.

Use energy-efficient LED bulbs instead of incandescent ones. Switch to 5-star rated appliances. Unplug devices when not in use. Use natural light during daytime. Set air conditioners to 24°C instead of 18°C. Consider solar panels for long-term savings. These small changes can reduce your bill by 20-30%.

Fixed charges cover the cost of maintaining the electricity connection, meter, and infrastructure. They are charged regardless of consumption. Variable charges (energy charges) depend on actual usage. Some bills also include taxes, fuel surcharges, and electricity duty.
