Section 3

No later than six months after the approval of the generation and load data provision methodology established for the day-ahead and intraday time frames referred to in Article 9(6) of Regulation (EU) 2015/1222, all TSOs shall jointly develop a proposal for a single generation and load data provision methodology for delivering the generation and load data required to establish the common grid model for long-term time frames. The proposal shall be subject to consultation in accordance with Article 6. The methodology shall take into account and complement the generation and load data provision methodology according to Article 16 of Regulation (EU) 2015/1222. When developing the generation and load data provision methodology, the requirements set in Article 16 of Regulation (EU) 2015/1222 shall apply. No later than six months after the approval of the common grid model methodology established for the day-ahead and intraday time frames referred to in Article 9(6) of Commission Regulation (EU) 2015/1222, all TSOs shall jointly develop a proposal for a common grid model methodology for long-term time frames. The methodology shall be subject to consultation in accordance with Article 6. The common grid model methodology shall take into account and complement the common grid model methodology developed pursuant to Article 17 of Regulation (EU) 2015/1222. The methodology shall enable the establishment of the common grid model for long-term capacity calculation time frames in capacity calculation regions where security analysis based on multiple scenarios pursuant to Article 10 is applied. When developing the common grid model methodology, the requirements set in Article 17 of Regulation (EU) 2015/1222 shall apply. All TSOs in capacity calculation regions, where security analysis based on multiple scenarios pursuant to Article 10 is applied, shall jointly develop a common set of scenarios to be used in the common grid model for each long-term capacity calculation time frame. When developing the common set of scenarios, the relevant requirements set in Article 18 of Regulation (EU) 2015/1222 shall apply. When developing the individual grid model for a long-term capacity calculation time frame in capacity calculation regions, where security analysis based on multiple scenarios pursuant to Article 10 is applied, each TSO shall apply the requirements set in Article 19 of Regulation (EU) 2015/1222.
