ENTSOG Gas Regional Investment Plan South 2017 - Main Report

Gas demand can vary through the year, the week and daily due to meteorological conditions, competing sources of energy, economical and residential activities. Therefore, demand fluctuations can be categorized by the period over which the variation in supply is required, in general in the year, the week, and the day. Figure 3.7 shows the modulation in demand in the South Region with: \\ fluctuations in the year mainly caused by the weather conditions when the gas is used for heating, \\ weekly cycle due to the economic activity, \\ and intra-daily factors linked to the economical and residential activities, and also fluctuations in other power generation, in particular, when CCGT are used as backup of intermittent renewable power generation (mainly wind).
