Article 20a 5.

In addition to the requirements laid down in Regulation (EU) 2019/943 and Directive (EU) 2019/944, Member States shall ensure that the national regulatory framework allows small or mobile systems such as domestic batteries and electric vehicles and other small, decentralised energy sources to participate in the electricity markets, including congestion management and the provision of flexibility and balancing services, including through aggregation. To that end, Member States shall, in close cooperation with all market participants and regulatory authorities, establish technical requirements for participation in the electricity markets, on the basis of the technical characteristics of those systems.
