ENTSO-E has published a report assessing the level of harmonisation of the rules for suspension and restoration of market activities established by the TSOs in accordance with the Emergency and Restoration (NCER) Regulation 2017/2196. The assessment was conducted by launching a survey with 59 detailed questions related to the process of suspending and restoring market activities.

The main reason for market suspension is to prevent the continuation of market activities that would either deteriorate an “emergency state” (one or more operational security limits are violated) or would decrease the effectiveness of the “restoration process” (re-establishing system operation and maintaining operational security after the blackout state or the emergency state) to the normal or alert state significantly.

The key findings in the report include the following:

  • As of 30 September 2020, TSO proposals from 15 Member States were approved by the relevant national regulatory authorities. However, TSOs from 4 Member States share the opinion that suspension and restoration of market activities is not necessary. Nevertheless, one of these 4 TSOs mentioned that implementation of methodologies from NCs and GLs may lead to need for suspension of market activities;
  • Even though TSOs have different approaches to suspension of market activities, no operational issues were identified as result of this divergence;
  • Few challenges are identified for future market activities; one such is that several areas would be worth discussing for harmonisation, like the common classification on the suspension of market activities.

In producing the report, ENTSO-E has been working closely with the Market European Stakeholder Committee (MESC) from 2019 through 2020. Furthermore, ENTSO-E organised a dedicated public webinar on 25 March 2020 that allowed all interested stakeholders to participate and discuss their views on this topic.
