In other words, if 17% of the energy consumed over a year in your zone is consumed in January, regardless of how much you actually consumedyour supplier will estimate that 17% of your annual energy consumption (calculated on the basis of your annual statement) was consumed in January.
The percentage of this annual consumption indicated for each period is then multiplied by the indexed tariff according to the parameters of the contract and all amounts are added together to give the total of the “energy” part of the bill.
Example : if your statement indicates that you have consumed 1000 kWh over a year, your bill would be broken down as follows:
170 kWh X January price + 150 kWh X February price + 120 kWh X March price + 70 kWh X April price + 30 kWh X May price + 10 kWh X June price, and and so on.
In any case, whether you have consumed a lot or whether you have completely cut off your heating, this means that the period of December will be counted as 16% of the annual consumption X the price of December (which was very high for the variables quarterly), while the March period will be billed to you as 12% of the consumption X the March price (which has fallen well in all contracts).
Energy saving efforts are therefore important to lower the amount of your bill, because they lower your total consumption, which will be used as the basis for the calculation, but no matter when you make those savings.
