All gas bill components explained clearly: from raw material costs to taxes and how conversion works.
The Italian natural gas bill has a structure similar to the electricity bill, but with specific features related to the unit of measurement and taxation.
Key conversions
Gas bill components
| Component | Description | Negotiable? |
|---|---|---|
| Gas supply | Cost of consumed gas (Smc), indexed to PSV or TTF | Yes |
| Transport & meter | National network (Snam) + local distribution | No (ARERA) |
| System charges | Balancing, quality and system operation | No (ARERA) |
| Taxes | Excise + regional surcharge + VAT | No (State) |
Smc vs kWh: the conversion
The meter measures volumes in cubic meters, which are converted to Smc through the correction coefficient (C). To compare prices with other energy sources, the gross calorific value (GCV) is used: 1 Smc ≈ 10.69 kWh.
Tips for businesses
Verify that the C coefficient applied is correct for your area. For consumption above 200,000 Smc/year, consider direct access to the wholesale market through a trader or bilateral contract, which can offer more advantageous terms than retail contracts.
