Fingrid’s customer organisations are working to implement the requirements of the EU network code on electricity emergency and restoration. The 24-hour operability requirement and automatic under-frequency load shedding system must be implemented by December 2022.
The Network Code for Emergency and Restoration (NC ER) specifies the common requirements for handling emergency, blackout and restoration states in the power system. NC ER harmonises the operation of power systems throughout the EU and with Third Countries.
Network planning requires national and international cooperation. A vital tool for this is Europe’s ten-year network development plan (TYNDP), which is drafted every two years by the European Network of Transmission System Operators for Electricity (ENTSO-E).
EU-wide network codes have been drawn up to promote cross-border exchanges in electricity. The network codes are divided into three areas: grid connection, system operation and market codes. The EU network codes are now complete. The network codes, which have entered into force, are outlined in this article.
