Network Code on Emergency and Restoration (ER)

​​The Network Code on Emergency and Restoration (NC ER) is a key factor for ensuring security and continuity of electricity supply across Europe, as it deals with the procedures and remedial actions to be applied in the Emergency, Blackout and Restoration states. This involves preparation of system defence, system restoration and re-synchronisation plans in advance, dealing with information exchange, procedures for operating when a system enters into one of these states and ad-hoc analysis of the incidents.

Latest Status Update (December​ 2015)

On 31 March 2015, the final Network Code on Emergency and Restoration and its supporting document were delivered to ACER for its opinion. On 24 June 2015, ACER delivered a positive opinion and recommended the code for adoption, along with a number of proposals for changes.

What Happens Next?

The Network Code will now be prepared for Comitology by the European Commission. It is expected to be presented to Member States for discussion in early 2016.


On 1 April 2014, ENTSO-E was mandated by the European Commission to draft these operational rules for electricity under REGULATION (EC) No 714/2009.

Following the requirements set out in ACER's framework guidelines (Topic 5: Emergency and Restoration), ENTSO-E prepared a preliminary working draft of the code – collecting information based on current best practices from TSOs across Europe regarding Emergency and Restoration. Two informal meetings were held with major stakeholder organisations and ACER to gain early input and proposals on the code.

In June 2014, a preliminary working draft was complete and so ENTSO-E launched the initial formal development and consultation phases on the NC ER. In order to present and discuss this draft and gain further input into the code's development, ENTSO-E held:

In December 2014, after an extensive work in collaboration with stakeholders, the Drafting Team Emergency and Restoration rewrote two sections of the network code: the chapter on market interactions and the article concerning the automatic low Frequency control scheme, which was completed based on an internal study on Low Frequency Demand Disconnection (LFDD) performed by TSOs experts.

To gain further input and proposals from all interested parties on these two specific topics, ENTSO-E held:

Stakeholder Engagement

Stakeholder engagement includes public consultations, DSO technical expert group meetings and public stakeholder workshops, as well as ad-hoc meetings and exchange of views with any interested parties as appropriate. The DSO Technical Expert Groups reflect the importance of involving Distribution System Operators, due to their significant role in contributing to overall system security. The technical experts in this group are designated from the DSO associations CEDEC, EDSO for Smart Grids, Eurelectric and GEODE.
