Transmission Reliability Margin definition

Transmission Reliability Margin or “TRM” shall mean the amount of transmission transfer capability necessary to provide reasonable assurance that the interconnected transmission network will be secure. TRM accounts for the inherent uncertainty in system conditions and the need for operating flexibility to ensure reliable system operation as system conditions change.

Examples of Transmission Reliability Margin in a sentence

  • The currently applied CNTC methods (at AT/IT, FR/IT, CH/IT, SI/IT) have been designed in such a way that they follow the ENTSO-E methodology which is based on the calculation of TTC (Total Transfer Capacity) and TRM (Transmission Reliability Margin).

  • Specifically:ETCF = NLF + NITSF + GFF + PTPF + RORF + OSF Where: NLF is the firm capacity set aside to serve peak Native Load forecast commitments for the time period being calculated, to include losses, and Native Load growth, not otherwise included in Transmission Reliability Margin or Capacity Benefit Margin.

  • NITSF is the firm capacity reserved for Network Integration Transmission Service serving Load, to include losses, and Load growth, not otherwise included in Transmission Reliability Margin or Capacity Benefit Margin.

  • TRM is the Transmission Reliability Margin for the Interface during that period.
