Frequently asked questions for power plants
- Who has to file the AD-1 declaration?
- The AD-1 declaration is required for holders of a generation power plant (self-producers and total grid injection), professional users with a license, power plants for purchase for own use, and electricity resellers under Art. 53 TUA. The exemptions under Art. 52 TUA (self-consumption from renewables below the statutory threshold, high-efficiency cogeneration, diplomatic and military uses) still require the annual informational declaration.
- When are the declarations due in 2026?
- D.Lgs. 43/2025 introduced a semi-annual cadence: H1 2026 (January-June) by September 30, 2026; H2 2026 (July-December) by March 31, 2027. Monthly down-payments are due by the 16th of the following month. The DM 10 March 2026 confirmed the tracciati and forms for the new flow.
- How is the electricity excise calculated?
- Excise follows the brackets under Art. 52 TUA, with different rates for industrial use, residential use, and consumption tiers. The exemptions under Art. 52 TUA cover self-consumption from renewables below the statutory threshold, high-efficiency cogeneration, diplomatic uses, and armed forces. Deklara applies the brackets automatically to the kWh entered per quadro.
- Is the surety bond paid every year?
- The surety bond is a continuous guarantee (bank or insurance bond, or cash deposit) sized against the estimated annual excise under the criteria of D.Lgs. 43/2025. It is posted once when the power plant opens and adjusted quarterly based on actual consumption, at the request of the local ADM office. It is not a recurring payment: it only needs to be renewed if the guarantor or the amount changes.

- Public price list, VAT excluded: Solo €199/year for 1 power plant, up to €599/year for 5 power plants, €949/year for 10, from €1,249/year for 25. Discount -15% on 3 years, -30% on 5 years.
