Understanding Electricity Rates
Rate Types
- • Flat Rate: Same price all day
- • Time-of-Use: Varies by time
- • Tiered: Increases with usage
Bill Components
- • Energy charges (kWh usage)
- • Fixed/service charges
- • Delivery/distribution fees
- • Taxes and regulatory charges
Understanding Electricity Costs
How Electricity Usage is Measured
Electricity consumption is measured in kilowatt-hours (kWh). One kWh equals 1,000 watts used for one hour. Your electricity bill is calculated by multiplying your kWh usage by the rate per kWh, plus any additional fees.
Calculation Formula
Energy Consumption (kWh) = Power (kW) × Time (hours)
Cost = Energy (kWh) × Rate (per kWh)
Example: 100W bulb for 10 hours = 0.1 kW × 10h = 1 kWh
Factors Affecting Your Bill
- •Usage Patterns: When and how much you use
- •Appliance Efficiency: ENERGY STAR vs. standard
- •Rate Structure: Flat, tiered, or time-of-use rates
- •Season: Summer cooling, winter heating
- •Home Size: Larger homes typically use more
