The Italian green electricity tariff comparison calculator estimates annual cost of Italian 100% renewable certified electricity. Base formula: Italian annual cost = Consumption (kWh/year) * Italian average price €/kWh + Annual fixed quota + Italian charges + 10% Italian VAT. Italian PUN 2026 (Prezzo Unico Nazionale) volatile 0.12-0.18 €/kWh, Italian end-user price 0.28-0.38 €/kWh after Italian system charges A2-A3-A4 and Italian VAT. Governed by Italian ARERA (Authority for Energy, Networks and Environment Regulation), Italian L. 124/2017 (Italian Tutela service abrogation from 1/7/2024), Italian D.M. 31/7/2009 (Italian Guarantees of Origin GO certify 100% renewable). Italian main brands: Italian Enel Energia (Rome 1962, free market leader), Italian Eni Plenitude, Italian A2A (Milan), Italian Edison (EDF group), Italian Sorgenia, Italian Iren. Comparison: USA green-e certified $0.10-0.18/kWh (NIST/EPA), UK green tariff 25-35 p/kWh (HMRC), French EDF Vert 0.18 €/kWh (DGFiP, INSEE), Spanish 0.18-0.25 €/kWh (INE), German Ökostrom 0.30-0.40 €/kWh (Destatis Statistisches Bundesamt).

Italian calculation formula

Italian cost calculation in 5 items:

• Italian energy component: Consumption * Italian PUN + Italian supplier spread (0.02-0.06 €/kWh)
• Italian transport and meter: 50-90 €/year fixed (regulated by Italian ARERA)
• Italian system charges: A2 (renewables), A3 (nuclear disposal), A4 (interruptibility) = 0.03-0.05 €/kWh
• Italian excise duties: 0.022 €/kWh (Italian D.Lgs. 504/1995)
• Italian VAT: 10% domestic up to 150 kWh/month, 22% above

Italian example: 3-person family 3,500 kWh/year. Italian energy 3,500 * 0.15 = 525 €. Transport 80 €. Charges 140 €. Excise 77 €. Net 822 €. Italian VAT 10% = 82 €. Italian total 904 €/year. Italian green tariff costs 0-3% more vs gray (~0-30 €/year extra) for Italian GO certification.

Italian history and context

Italian electric market liberalized since 1999 (Italian D.Lgs. 79/1999, "Bersani decree") with Italian L. 124/2017 abrogating Italian Tutela Service from 1/7/2024 (originally 1/1/2022, extended). Italian ARERA regulates Italian tariffs, Italian service quality, Italian system charges. Italian Guarantees of Origin GO introduced by Italian D.M. 31/7/2009 (implements EU 2009/28/CE): 1 Italian GO = 1 MWh produced by Italian renewable source. Italian electric market 60 billion €/year (Italian ARERA 2024) with 30 million Italian families connected. Italian renewable share 41% electric mix (Italian Terna 2024). Italian historic brands Italian Enel Energia (1962), Italian A2A (1903 Edison Milan), Italian Edison (1884), Italian Eni Plenitude (2017 from ENI group). Italian free market 24 million clients (80%), Italian residual Maggior Tutela Service 6 million (Italian Vulnerable post 1/7/2024).

Italian green tariffs table 2026

Italian PUN-indexed tariffs follow market (Italian winter price spike risk). Italian fixed 12-36 month tariffs protect against spikes but cost +5-10% if Italian PUN drops. Italian Sorgenia and NeN often cheapest on average Italian consumption.

5 Italian numerical examples

Example 1 - Italian single 1,800 kWh/year: Italian Sorgenia Sunlight 0.147 €/kWh + 60 € quota = 264 + 60 = 324 € + Italian charges+VAT 144 € = 468 € Italian total. Italian green tariff savings 30-50 €/year vs Italian Maggior Tutela.

Example 2 - Italian 4-person family 4,500 kWh/year: Italian NeN Speciale 0.140 €/kWh + 0 fixed quota = 630 € energy + Italian charges+VAT 320 € = 950 € Italian total. Italian saving vs ENI Plenitude 0.148 €/kWh = 36 €/year.

Example 3 - Italian Milan apartment 6,000 kWh/year: Italian A2A Click Green (Milan group) 0.145 €/kWh + 96 € = 966 € + Italian charges+VAT 480 € = 1,446 € Italian total. Italian green tariff with Italian GO 100% renewable certified.

Example 4 - Italian fixed vs indexed comparison: 3,500 kWh/year. Italian Edison fixed 24 months 0.152 €/kWh = 532 €. Italian Eni Plenitude indexed avg 2026 0.148 €/kWh = 518 €. Italian indexed saves 14 €/year if Italian PUN stable, but risk +200-400 € if PUN spikes.

Example 5 - Italian green tariff + PV self-production: 3,500 kWh consumption, PV 6 kWp produces 6,500 kWh, self-consumption 40% = 2,600 kWh. From Italian grid only 900 kWh * 0.28 = 252 € + 80 € quota = 332 € + Italian net metering 3,900 * 0.15 = 585 € income. Italian balance +253 €/year (net income) with Italian GSE green tariff.
