National Transmission System (NTS) operational limits depending on the Line Pack (LP) [the line pack is the actual quantity of gas existing at a certain moment in the TRANSGAZ gas transmission pipeline system]:
- NTS optimum status: LP = 62.0 ÷ 65.0 mil.Sm3 = 664,144,000 ÷ 696,280,000 kWh
- NTS normal status: LP is comprised between 57.0 ÷ 62.0 mil.Sm3 = 610,584,000 ÷ 664,144,000 kWh or LP is comprised between 65.0 ÷ 68.0 mil.Sm3 = 696,280,000 ÷ 728,416,000 kWh
- NTS pre-alert status: LP is comprised between 52.0 ÷ 57.0 mil.Sm3 = 557,024,000 ÷ 610,584,000 kWh or LP is comprised between 68.0 ÷ 70.0 mil.Sm3 = 728,416,000 ÷ 749,840,000 kWh
- NTS alert status: LP < 52.0 mil.Sm3 = 557,024,000 kWh or LP > 70.0 mil.Sm3 = 749,840,000 kWh
The operational limits are updated with the NTS transmission infrastructure developments and the need to implement new transmission scenarios.
