NEPLAN | Net Transfer Capability (NTC)

back to overview

This module calculates the limiting MW transfer value between two control areas (source and sink) that is available without any violation of security limits.

General Characteristics

  • ENTSO-E methodology (load flow based, MW generation shift)
  • Large flexibility in limit handling (individual activation of limits)
  • Consideration of user-defined contingency scenarios
  • Consideration of Transmission Reliability Margin (TRM )


The outcome of the calculation is a list of the limit violations for every step of increasing the MW transfer from source to sink as for

  • the base case
  • each contingency case

The module provides calculation of the Total Transfer Capacity (TTC) and the Net Transfer Capacity (NTC).
