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 Azienda 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 Azienda Online from Sienergy and a spread of 0.180 €/Smc, as of June 2026 you are currently paying about 0.684 €/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 Azienda Online. Here are the pros and cons of a variable-price contract.
- When the PSV falls, your company's gas costs decrease accordingly without having to renegotiate
- There is no fixed contract term and you can switch supplier at any time without early exit penalties
- During periods of high PSV volatility, gas costs can rise significantly, making budget planning more complex
- The gas price (€/Smc) stays fixed for the entire contract, regardless of how the PSV moves
- Ideal for businesses that need to forecast gas costs precisely when planning their operating budget
- If the PSV falls after activation, you continue paying the agreed price without benefiting from market drops
