Division 1.7

When defining appropriate network areas in and between which congestion management is to apply, TSOs shall be guided by the principles of cost-effectiveness and minimisation of negative impacts on the Internal Electricity Market. Specifically, TSOs may not limit interconnection capacity in order to solve congestion inside their own control area, except for the above mentioned reasons and reasons of operational security^f1. If such a situation occurs, this shall be described and transparently presented to all the users by the TSOs. Such a situation may be tolerated only until a long-term solution is found. The methodology and projects for achieving the long-term solution shall be described and transparently presented to all the users by the TSOs.
