CHAPTER 3Data exchange between TSOs and DSOs within the TSO's control area
Article 43Structural data exchange
1.
Each TSO shall determine the observability area of the transmission-connected distribution systems which is needed for the TSO to determine the system state accurately and efficiently, based on the methodology F1which must be developed by the regulatory authority from time to time.
2.
If a TSO considers that a non-transmission-connected distribution system has a significant influence in terms of voltage, power flows or other electrical parameters for the representation of the transmission system's behaviour, such distribution system shall be defined by the TSO as being part of the observability area F2....
3.
The structural information related to the observability area referred to in paragraphs 1 and 2 provided by each DSO to the TSO shall include at least:
(a)
substations by voltage;
(b)
lines that connect the substations referred to in point (a);
(c)
transformers from the substations referred to in point (a);
(d)
SGUs; and
(e)
reactors and capacitors connected to the substations referred to in point (a).
4.
Each transmission-connected DSO shall provide the TSO with an update of the structural information in accordance with paragraph 3 at least every 6 months.
5.
At least once a year, each transmission-connected DSO shall provide the TSO, per primary energy sources, the total aggregated generating capacity of the type A power generating modules subject to requirements of Regulation (EU) 2016/631 and the best possible estimates of generating capacity of type A power generating modules not subject to or derogated from Regulation (EU) 2016/631, connected to its distribution system, and the related information concerning their frequency behaviour.
