Network Code on Operational Security (OS)

​Please note this network code will be merged into the Single System Operation Guideline​

Go to System Operation Guideline​

​The Operational Security Network Code (OS) will provide the basis for the power system to function with a satisfactory level of security and quality of supply, as well as efficient utilization of infrastructure and resources. It will do so by focusing on common operational security principles, pan-European operational security, coordination of system operation, and some important aspects for grid users connected to the transmission grid.

 

Latest Status Update (July 2015)
 

The Network Code on Operational Security has been recommended by ACER with a small number of remarks. These remarks will be explored with the EC and ACER before they begin the process of processing the network code into a European law. During this phase, ENTSO-E is seeking to provide the appropriate support and engage in discussions with Member States, Institutions and stakeholders to contribute to a smooth adoption later this year of the code in a form that will create strong benefits for European Consumers.

An overview of the latest developments for all network codes is available.

 

Stakeholder Engagement

ENTSO-E’s stakeholder engagement will comprise of 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.

 
All material, including minutes and presentations from meetings will be made public.
