Critical infrastructure

Critical infrastructure as defined in Article 2, point (4), of Directive (EU) 2022/2557, the CER Directive. The AI Act gives no definition of its own here but aligns with that framework.

The official source remains authoritative. This is general information about obligations and not legal advice. See this object on the map

What this object links to

Every relation appears below as a path: from the source with its locator, through the conditions and exceptions of the object carrying the relation, to the consequence. A locator belongs to a statement in the data and not to a relation, so the source is the source anchor of the carrying object.

What this object states

Official fact

Attributable to a named primary source, with a locator. Where they differ, the official source prevails.

Article 3(62) provides that critical infrastructure means critical infrastructure as defined in Article 2, point (4), of Directive (EU) 2022/2557.

Our interpretation

Our own reading. It can change without the law changing, and it is not the position of a supervisory authority.

This cross-reference looks like a formality but has direct consequences for the risk class. Annex III, point 2, classifies AI systems as high risk where they are intended to be used as safety components in the management and operation of critical digital infrastructure, road traffic, or the supply of water, gas, heating or electricity. Anyone wanting to know whether they fall within that scope must consult the CER Directive and the national designation of critical entities rather than invent a definition of their own. Organisations get this wrong because designation differs per Member State.

Recommended step

A practical step we consider appropriate. Not an obligation following from the Regulation.

Record whether your organisation or your customer has been designated as a critical entity under the national transposition of Directive (EU) 2022/2557, and link that determination to your risk classification under Annex III, point 2, with date and source.
