How to read your electricity bill

A practical guide to understanding every line of the Italian electricity bill and identifying savings opportunities.


The Italian electricity bill consists of four main cost components. Understanding this structure is the first step to optimizing your company's energy costs.

The four main components

45-55%
Energy Supply
15-20%
Transport & Meter
10-15%
System Charges
12-15%
Taxes (Excise + VAT)
  • Energy supply cost — the actual cost of consumed energy. This is the only component where suppliers compete in the free market. It includes the energy price (PE), dispatching (PD), and grid losses.
  • Transport and meter management cost — covers national grid transmission (Terna) and local distribution. Set by ARERA and equal for all suppliers.
  • System charges — funds renewable incentives, nuclear decommissioning, social bonuses, and other system costs. Also regulated by ARERA.
  • Taxes — excise duty on energy and VAT. The excise for businesses is 0.0125 EUR/kWh for consumption up to 200,000 kWh/month, with exemptions on the first tranche for industrial use.

Time-of-use bands

Consumption is measured by time band (F1, F2, F3). The F1 band carries the highest price. Shifting loads to F2 and F3 bands can generate significant savings.

BandHoursDaysRelative Cost
F1 (peak)8:00 AM – 7:00 PMMon – FriHigh
F2 (mid-peak)7–8 AM & 7–11 PMMon – Fri + Sat 7 AM–11 PMMedium
F3 (off-peak)11:00 PM – 7:00 AMNight + Sun & HolidaysLow

How to identify savings opportunities

Compare your average kWh price across bands against market benchmarks. If the energy component exceeds 50-60% of the total bill, there is meaningful room for contract optimization. For energy-intensive companies, check eligibility for system charge exemptions under EU regulations.

Key tip: Focus your analysis on the "Energy Supply" component — it is the only negotiable item and accounts for over half the bill. Always ask your supplier for the price breakdown by time band (F1, F2, F3) to properly compare offers.
