Today ENTSO-E publishes the report on Inter-TSO coordination in connection network codes implementation.
Pursuant to Commission Regulations 2016/631 (NC RfG), 2016/1388 (NC DCC) and 2016/1447 (NC HVDC) transmission system operators (TSOs) are responsible to coordinate when establishing certain Connection Network Code (CNC) requirements at national level. For some requirements, the coordination shall take place at the synchronous area level; for others, it is required between adjacent TSOs.
ENTSO-E has prepared a public report monitoring the explicitly required coordination or reasonably undertaken collaboration between TSOs when implementing the CNCs at national level, because of the cross-border impact of these specifications mostly at synchronous area level.
