4. Introduction
Short description of the NTC calculation scenario i.e. observed border between two areas, in one or two slides (list of active tie-lines given by voltage levels? single line diagram of bordering substations with observed tie-lines? position in the systems with geographical scope?)
Xxxxx 4 4

5. NTC Calculation Prerequisites: BCE&NTF
Explanation of assumed Base Case Exchange programs (BCE) between two areas for observed regimes and their physical cross-border flows – Notified Transmission Flow (NTF) (why these amounts? why these directions?)
Xxxxx 5 5

6. NTC Calculation Prerequisites: TRM
Explanation of assumed value for Transmission Reliability Margin (TRM) (if any? if exists, why this value? which kind of uncertainties are included there?)
Xxxxx 6 6

7. NTC Calculation Prerequisites: AAC
Explanation of Already Allocated Capacity (AAC) if exists at observed border (if exists, why this value? which kind of already allocated transmission rights are included there?)
Xxxxx 7 7

8. NTC Calculation Prerequisites: GSK
Explanation of applied Generation Shift Keys (GSK) in both areas in one or two slides (why this type of shift keys? list of generation units which are engaged? what are the possible limits in generation shifting in both directions (in case of power increasing and power decreasing)? what is the solution in case of exceeded power limit?)
Xxxxx 8 8

9. NTC Calculation Procedure: Algorithm
Short description of applied NTC calculation procedure in one or two slides (with algorithm chart) taking into account local specifics and necessary assumptions (do you perform usually any kind of capacity calculation and capacity allocation in your practice? if yes, which kind of standard procedure is usually applied in capacity calculation? do you have some expected loop flows?)
Xxxxx 9 9

10. NTC Calculation Procedure: MON, CON, SUB
Short description of applied auxiliary files for calculation (MON, CON, SUB) (explain list of observed critical branches and critical outages in considered TSOs? what are the specific loading limits applied within the calculation process?)
Xxxxx 10 10

11. NTC Calculation Procedure: Static and Dynamic Security Calculations
Explanation of achieved static/dynamic security limits within the calculation process for each observed regime and each considered direction (if dynamic security limits exist, please stress critical elements and critical contingencies? explain them?)

12. NTC Calculation Results
Table with calculation results for observed border and observed regimes (please see an example below)
