Commission Regulation (EU) 2017/1485 of 2 August 2017 establishing a guideline on electricity transmission system operation (Network Code on System Operation or System Operation Guideline - SOGL) received a positive vote in comitology on 4 May 2016.

ACER Recommendation on reasoned amendments to the Capacity Allocation and Congestion Management Regulation proposes changes to a wide range of topics, including amendments to the SOGL

Various amendments to the SOGL stem out directly from the revisions of the CACM Regulation. In particular:

  • specific content is moved from the CACM Regulation to the SOGL to benefit of synergies;
  • amendments mainly relate to data exchange, the common grid model, the operational security analysis and scheduling.

 


The Network Code on System Operation have been designed by ENTSO-E, which 
merged into one legislative document the earlier three draft codes for operation in normal conditions (relating to operational security, operational planning & scheduling and load-frequency control & reserves).

 

The Network Code on System Operation lays down detailed guidelines on:


(a) requirements and principles concerning operational security;

 

(b) rules and responsibilities for the coordination and data exchange between:

 

- Transmission System Operators (TSOs),

 

- TSOs and Distribution System Operators (DSOs), and

 

- TSOs or DSOs and Significant Grid Users (SGUs);

 

in operational planning and in close to real-time operation;


(c) rules for training and certification of system operator employees;


(d) requirements on outage coordination;


(e) requirements for scheduling between the TSOs' control areas; and


(f) rules aiming at the establishment of a Union framework for load-frequency control and reserves.
