Following the Framework Guidelines on Electricity System Operation, four network codes were initially developed:
- Network Code on Operational Security
- Network Code on Operational Planning and Scheduling
- Network Code on Load-frequency Control and Reserves
- Network Code on Emergency and Restoration
During the adoption process led by the European Commission, the Network Codes on Operational Security, Operational Planning and Scheduling and Load-frequency Control and Reserves were merged into the Guideline on Electricity Transmission System Operation.
For information related to the adoption of Network Codes, consult the European Commission's webpage on the Electricity Cross-Border Committee.
