Is fixed or variable price better with Sienergy in June 2026?
The PSV (Punto di Scambio Virtuale) is Italy's monthly reference price for natural gas: when it rises your bill increases, when it falls you save automatically. Gas Online is a variable-price offer: its cost directly follows the PSV. The chart shows how your price has changed over time.
With the indexed offer Gas Online from Sienergy and a spread of 0.150 €/Smc, as of June 2026 you are currently paying about 0.654 €/Smc.

Fixed or variable gas tariff: here are the differences
In the free natural gas market, suppliers can offer either fixed-price or indexed tariffs. With a fixed price, the cost of gas (€/Smc) stays the same for the entire duration of the contract, whereas with indexed offers the price of gas changes each month based on the PSV (Punto di Scambio Virtuale, Italy's wholesale gas reference index).
Sienergy offers exclusively PSV-indexed contracts, such as Gas Online. Here are the pros and cons of a variable-price contract.
- When the natural gas market price falls, your bill decreases automatically in line with the change
- There is no fixed contract term and you can switch offer or supplier at any time without early exit penalties
- During periods of high gas price volatility, your bill can rise significantly and monthly costs become harder to predict
- The gas price (€/Smc) stays fixed for the entire contract, regardless of how the PSV moves
- Ideal for those who heat their home with gas and want a predictable bill with no unexpected increases in winter
- If the PSV falls after activation, you continue paying the agreed price without benefiting from market drops
