Fixed or variable electricity tariff: here are the differences
In the free electricity market, suppliers can offer either fixed-price or indexed tariffs. With a fixed price, the cost of electricity (€/kWh) stays the same for the entire duration of the contract, whereas with indexed offers the price of electricity changes each month based on the PUN (Prezzo Unico Nazionale, Italy's national wholesale electricity index).
Sirio offers exclusively PUN-indexed contracts, such as Unica Stella. Here are the pros and cons of a variable-price contract.
- When the energy 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 energy price volatility, your bill can rise significantly and monthly costs become harder to predict
- The electricity price (€/kWh) stays fixed for the entire contract, regardless of how the PUN moves
- Ideal for those who want a predictable energy bill with no unexpected changes
- If the PUN falls after activation, you continue paying the agreed price without benefiting from market drops
