What units do we use to submit energy data? What are the conversion factors used?

Electricity and natural gas data is sourced automatically from the meter operators in kilowatt hours (kWh). You typically report the other energy data in the units in which it is billed, e.g. litres for heating oils and transport fuels, tonnes for wood chips and solid fuels. The system automatically converts all energy consumption to kWh on a net calorific value basis. It is very important that you enter data in the correct units.

The following are the current conversion factors used to convert energy consumption from the reported units to kilowatt-hours (kWh). The conversion factors are based on net calorific values and they can change slightly from year to year.
