Section 2

By 10 months after the entry into force of this Regulation all TSOs shall jointly develop a proposal for a single methodology for the delivery of the generation and load data required to establish the common grid model, which shall be subject to consultation in accordance with Article 12. The proposal shall include a justification based on the objectives of this Regulation for requiring the information. The proposal for the generation and load data provision methodology shall specify which generation units and loads are required to provide information to their respective TSOs for the purposes of capacity calculation. The proposal for a generation and load data provision methodology shall specify the information to be provided by generation units and loads to TSOs. The information shall at least include the following: information related to their technical characteristics; information related to the availability of generation units and loads; information related to the schedules of generation units; relevant available information relating to how generation units will be dispatched. The methodology shall specify the deadlines applicable to generation units and loads for providing the information referred to in paragraph 3. Each TSO shall use and share with other TSOs the information referred to in paragraph 3. The information referred to in paragraph 3(d) shall be used for capacity calculation purposes only. No later than two months after the approval of the generation and load data provision methodology by all regulatory authorities, ENTSO for Electricity shall publish: a list of the entities required to provide information to the TSOs; a list of the information referred to in paragraph 3 to be provided; deadlines for providing information. By 10 months after the entering into force of this Regulation all TSOs shall jointly develop a proposal for a common grid model methodology. The proposal shall be subject to consultation in accordance with Article 12. The common grid model methodology shall enable a common grid model to be established. It shall contain at least the following items: a definition of scenarios in accordance with Article 18; a definition of individual grid models in accordance with Article 19; a description of the process for merging individual grid models to form the common grid model. All TSOs shall jointly develop common scenarios for each capacity calculation time-frame referred to in Article 14(1)(a) and (b). The common scenarios shall be used to describe a specific forecast situation for generation, load and grid topology for the transmission system in the common grid model. One scenario per market time unit shall be developed both for the day-ahead and the intraday capacity calculation time-frames. For each scenario, all TSOs shall jointly draw up common rules for determining the net position in each bidding zone and the flow for each direct current line. These common rules shall be based on the best forecast of the net position for each bidding zone and on the best forecast of the flows on each direct current line for each scenario and shall include the overall balance between load and generation for the transmission system in the Union. There shall be no undue discrimination between internal and cross-zonal exchanges when defining scenarios, in line with point 1.7 of Annex I to Regulation (EC) No 714/2009. For each bidding zone and for each scenario: all TSOs in the bidding zone shall jointly provide a single individual grid model which complies with Article 18(3); or each TSO in the bidding zone shall provide an individual grid model for its control area, including interconnections, provided that the sum of net positions in the control areas, including interconnections, covering the bidding zone complies with Article 18(3). Each individual grid model shall represent the best possible forecast of transmission system conditions for each scenario specified by the TSO(s) at the time when the individual grid model is created. Individual grid models shall cover all network elements of the transmission system that are used in regional operational security analysis for the concerned time-frame. All TSOs shall harmonise to the maximum possible extent the way in which individual grid models are built. Each TSO shall provide all necessary data in the individual grid model to allow active and reactive power flow and voltage analyses in steady state. Where appropriate, and upon agreement between all TSOs within a capacity calculation region, each TSO in that capacity calculation region shall exchange data between each other to enable voltage and dynamic stability analyses.
