ENTSOG Tariff NC - Implementation Document 2nd Edition

GENERAL – APPLICATION OF THE TAR NC AT DIFFERENT POINTS ON TRANSMISSION NETWORK The scope of the TAR NC is not homogeneous, as it differs with respect to different types of points. Therefore, the scope of the TAR NC can be explained from two perspectives: which rule is concerned and which point on the transmission system is concerned. ‘ Which rule is concerned ’: Article 2(1) envisages applying all of the TAR NC rules by default to all the points on the transmission network. However, some of its rules have a ‘limited scope’ and apply only at IPs by default, which is the same scope as the CAM NC. So the TAR NC rules in fact split into ‘limited scope’ rules and ‘broader scope’ rules as shown in Figure 2. This Figure shows such a distinction from the perspective of which TAR NC rule is concerned.
