Flow-based Allocations [11.1]

Flow-based parameters
Regulation Article	TR article 11.1.b
Regulation text	For their control areas TSOs or, if applicable, transmission capacity allocators, shall calculate and provide the following information to the ENTSO for Electricity sufficiently in advance of the allocation process: the relevant flow-based parameters in case of flow-based capacity allocation.
Detailed description	Refer to the definition of ‘flow-based parameters’. Final data only shall be published. For each time horizon, parameters are published with given resolution: - Day ahead and intraday: MTU - Month ahead: Monthly - Year ahead: Yearly. The following attribute applies to the day ahead and intraday publications for the Nordic region and for the long-term publications in both Core and Nordic regions: Faac The following attributes apply to the publications for the Nordic region only: FRA and F0 The following attributes apply to the publications for the Core region only: F0_wce (also referred to as F0_core), F0_all, Ramr The following attributes apply to the day ahead and intraday publications for the Core region only: F_nrao, F_LTN, CVA, F_uaf, minRAM_target The following attributes apply to the long-term publications only: U and cos phi. In and Out bidding zones are the same in case the CNE is internal to a given bidding zone. A positive value in in the reference flow (Fref) indicates that in the base case energy will flow in the direction indicated by the In and Out bidding zones, while a negative value indicates that energy will flow in the opposite direction. A positive value in the expected flow change due to non-costly remedial actions (F_nrao) indicates that the RAM on the CNEC is increased by the optimization of remedial actions, while a negative value indicates the RAM is decreased. Combined dynamic, external and anonymous constraints do not contain any references to grid elements or contingencies. With reference to Article 2(d) of Council Directive 2008/114/EC, the CNEC identifier may be replaced with an anonymous identifier, which shall be stable across all relevant capacity calculation time frames. With reference to the same Article, the anonymous identifier may not even be stable. For such CNEC, no references to grid elements or Orientation will be included.
Specification of calculation	For the Core region: - Refer to chapter 3 of the Explanatory note on the day-ahead and intraday common capacity calculation methodologies for the Core CCR - Refer to Title 3 (Capacity Calculation Process) of the long-term capacity calculation methodology for the Core CCR For the Nordic region: - Refer to articles 12 and 13 of all TSOs’ of the Nordic Capacity Calculation Region proposal for capacity calculation methodology Refer to articles 10 and 11 of the long-term capacity calculation methodology for the Nordic CCR
Primary owner of the data	TSO
Data provider	TSO, Transmission Capacity Allocator (TCA) or Coordinated Capacity Calculators (CCC) on behalf of TSOs
Aggregation	Not applicable
Publication deadline for ENTSO-E	For day ahead and intraday time horizons: One hour before spot market gate closure For month ahead time horizon: Two working days before the monthly allocation process For year ahead time horizon: One week before the yearly allocation process but no later than 15 December
Updates	Normally not expected
