4.2.2 PEAK CONSUMPTIONS

4.2.2.1 Peak and 14-day peak

The day of highest consumption in the year is a key input of the network design process and represents one of the most stressful situations to be covered by the gas transmission system. The design and operation of a system is also challenged by the availability of supply sources during periods of high consumption. On this basis, ENTSOG has considered the highest 14-day demand period as significant for testing the resilience needs of the system. The table below shows the highest daily consumption, and the highest 14-days average consumption from the last five winters at EU aggregated level.
