ENERGY GLOSSARY / ALL TERMS ↗NeoBid’s own overview.
Data and metering
What does gross calorific value mean?
Gross calorific value describes a fuel’s energy content under defined conditions and includes heat recoverable when water vapour condenses. In gas billing, it is used to convert volume to energy.
The data basis, contract scope and distinction from related terms are essential for applying this to a portfolio. Gross and net calorific values are not identical. Terms, units and reference conditions cannot be freely interchanged when checking bills.

PROPERTY PRACTICE
What does this mean for your portfolio?
Use the gross calorific value stated for the relevant billing period. When comparing gas consumption, kWh or MWh are more informative than an unchecked comparison of cubic metres. Gross and net calorific values must not be equated.
An example.
Our own example: 1,000 m³ of operating volume is converted to 10,450 kWh using a conversion factor of 0.95 and a gross calorific value of 11 kWh/m³. Gross calorific value is one of the two conversion factors.
Simplified example to explain the term. Actual metering data, the supply concept and agreed terms are decisive.
WHAT MATTERS
Three questions for your portfolio.
Are the units and reference conditions correct?
Has the gas conversion factor also been included?
Make the distinction clear
Distinction from the gas conversion factor: gross and net calorific values are not identical. Terms, units and reference conditions cannot be freely interchanged when checking bills.
