Dear reader,
The cost of energy is – together with the fixed monthly cost, a sort of “fee” independent of consumption – the only price component on which gas and electricity operators can compete. The rest are taxes, VAT, system charges and expenses for transport and management of the meter: all costs that are established either by the State or by Arera. System charges are a sort of surcharges that serve to finance many activities, but above all the social bonus for low-income citizens and very energy-intensive businesses. The cost of transporting and managing the meter varies depending on the area of the country and is used to ensure that operators can cover the costs of distributing the gas.
When you consult the Offer Portal, the overall annual cost that is shown includes all these items: it corresponds to the annual bill, nothing else needs to be added to it.
