The Security of Gas Supply Regulation empowers the Commission to adopt delegated acts to update the composition of the risk groups, and to reflect the evolution of the major transnational risks to the security of gas supply in the Union.

The update will reinforce the security of supply architecture of the EU and reflect the evolution of the gas system.
