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).
Sienergy offers exclusively PUN-indexed contracts, such as Energia Business Online Flex. Here are the pros and cons of a variable-price contract.
- When the PUN falls, your company's energy 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 PUN volatility, energy costs can rise significantly, making budget planning more complex
- The electricity price (€/kWh) stays fixed for the entire contract, regardless of how the PUN moves
- Suited to businesses that require a high degree of energy cost predictability when planning operating expenses
- If the PUN falls after activation, you continue paying the agreed price without benefiting from market drops
