Act No.CLXVI of 2012 on the identification, designation and protection of essential systems and facilities.

Designation or withdrawal of designation of facilities as part of the national essential system may be initiated by the operator of a given facility or by an organ with proposal making power. The same is valid for facilities of European relevance with the difference that a member state of the European Economic Area may also initiate the designation process. A register of designated facilities must be kept. According to Art. 6 a safety operational plan must be prepared by the operator of the designated facility. Article 8 provides rules of control on the operation of designated facilities. Articles 10-13 contain special provisions regarding facilities of the energy sector, including electric energy, oil and liquid hydro-carbons, and natural gas.
