Year-ahead individual grid models
Article 66
1. Each TSO shall determine a year-ahead individual grid model for each of the scenarios developed pursuant to Article 65, using its best estimates of the variables defined in Article 65(1). Each TSO shall publish its year-ahead individual grid models on the ENTSO for Electricity operational planning data environment in accordance with Article 114(1). 2. When defining its year-ahead individual grid model, each TSO shall: (a) agree with the neighbouring TSOs upon the estimated power flow on HVDC systems linking their control areas; (b) balance for each scenario the sum of: (i) net exchanges on AC lines; (ii) estimated power flows on HVDC systems; (iii) load, including an estimation of losses; and (iv) generation. 3. Each TSO shall include in its year-ahead individual grid models the aggregated power outputs for power generating facilities connected to distribution systems. Those aggregated power outputs shall: (a) be consistent with the structural data provided in accordance with the requirements of Articles 41, 43, 45 and 48; (b) be consistent with the scenarios developed in accordance with Article 65; and (c) distinguish the type of primary energy source.
