The first ELE WG meeting of 2021 laid the foundation for discussion of the two main deliverables of the group for the year: the report on the “Security of supply” and the technical support that will be provided to the Israeli Electricity Authority (PUA) through a study to identify the main regulatory principles and best practice to assess congestion management and allocation of transmission rights. The report on "Security of supply" will give a view on quality and security of supply in the different countries including the availability of networks and critical infrastructures. This report will be performed under the framework of the cooperation agreement with CEER and ECRB.
