Every home charger installed in Italy from 1 January 2027 will have to be certified for smart charging. Article 23 of Legislative Decree 5/2026, which transposes the EU's revised Renewable Energy Directive (RED III), requires all new or replaced charging points of standard power that are not open to the public to be certified under Annex X of CEI 0-21, Italy's technical rule for connecting to the low-voltage grid. The energy regulator ARERA cites the provision, and the 1 January start, in a resolution of 6 October.
With eight weeks to go, the industry is not sure it will be ready. An accredited certification body, CESI, was made official only about a week ago, Omar Imberti, who coordinates the e-mobility group of the industry federation ANIE, told Vaielettrico. ANIE is considering asking the energy ministry (MASE) for a transition period of a few months so that every manufacturer can certify its products. An engineer who wrote to the site said none of the charger makers he had contacted was ready.
What the rule requires
| From 1 January 2027 | |
|---|---|
| Applies to | New or replaced charging points up to 22 kW that are not open to the public |
| Typical cases | Home wallboxes, condominium garages, company car parks |
| Requirement | Certification under Annex X of CEI 0-21, with a charging infrastructure controller (CIR) |
| Chargers already installed | Not affected unless they are replaced |
| Legal basis | Article 23, Legislative Decree 5/2026 |
The 22 kW ceiling and the typical cases are set out in a guide by the charger maker V2C.
The controller, called a CIR in Italian, does the work. It reads the household's consumption from the smart meter and lowers or pauses the charging power so the home stays within its contracted power. Under the revised standard it must take that data over the meter's "Chain 2" channel wherever the channel is available. It also cuts the charger off automatically when the grid frequency drops, to help prevent blackouts, and prepares it for flexibility services that grid operators could buy later.
The controller can be built into the wallbox or fitted as a separate unit between the meter and the charger, including with chargers that can already talk to the meter, according to Vaielettrico. Two companies sell such units in Italy today. An installer told the site the rule will push up the purchase price of a home charger, although installation could cost less because no separate cable or energy meter is needed.
What it means for Tesla owners
Tesla sells its Wall Connector in Italy for homes and workplaces. TeslAnt found no statement from Tesla on whether it will be certified under Annex X by January. The obligation applies to chargers installed from 1 January, so a charger fitted before then does not need the certification, and one already on the wall can stay.
ARERA is also reworking the rules for private charging. A consultation that closes on 9 November proposes reopening in 2027, with new requirements, the trial that has let households draw up to 6 kW at night and on public holidays, and possibly making it permanent from 2028, Vaielettrico reports. It also proposes a new contract type for garages that are not part of a home.
