1Kw running for 1 hour = 1Kwh
0.5 Kw (500w) running for 2 hours = 1Kwh
2kW running for 30 minutes also = 1Kwh
1Kwh is also known as ‘1 unit of electricity’
The company supplying the energy will have set the price for the unit of electricity. This and other details that make up the bill will be detailed in the supplier’s terms and conditions. Such terms and conditions are known as tariffs.
With more complex tariffs, electricity usage will be charged while taking into account other factors such as:
- Time of day.
- Maximum demand at any given point in time.
- Seasonal variations.
- Power factor that electricity has been taken at.
- System usage charges.
- Payment methods.
The electricity bill must clearly set out all this information so that it is easy to establish how the total amount charged has been calculated.
