The readings make it possible to know the amount of natural gas consumed.

Consumption is calculated based on the difference in m3 of gas between both readings (current and previous) and the result is converted into another energy measure: kWh. This transformation is called conversion coefficient. The consumption in kWh resulting from this conversion is the number mentioned in “Billing details” as “Variable rate”.

In this item, Audax Renewables shows the m3 consumption over the last 14 months.
