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.
Transmission Reliability Margin means that amount of transmission transfer capability necessary to ensure that the interconnected transmission network is secure under a reasonable range of uncertainties in system conditions.
Transmission Reliability Margin or ‘TRM’ means the margin factored in the total transfer capability for ensuring secure operation of the Cross Border Transmission Link under a reasonable range of uncertainties in system conditions.
