Lists of relevant grid elements
Article 87
1. By 3 months after the approval of the methodology for assessing the relevance of assets for outage coordination in Article 84(1), all TSOs of each outage coordination region shall jointly assess, on the basis of this methodology, the relevance for the outage coordination of grid elements located in a transmission system or in a distribution system including a closed distribution system and shall establish a single list, per outage coordination region, of relevant grid elements. 2. The list of relevant grid elements of an outage coordination region shall contain all grid elements of a transmission system or a distribution system, including a closed distribution system located in that outage coordination region, which are identified as relevant by application of the methodology established pursuant to Article 84(1). 3. All TSOs of an outage coordination region shall jointly make the list of relevant grid elements available on the ENTSO for Electricity operational planning data environment. 4. Each TSO shall notify to its regulatory authority the list of relevant grid elements for each outage coordination region in which it participates. 5. For each internal relevant asset which is a grid element, the TSO shall: (a) inform the owner of the relevant grid element about its inclusion in the list; (b) inform DSOs about the relevant grid elements which are connected to their distribution system; and (c) inform CDSOs about the relevant grid elements which are connected to their closed distribution system.
