Gas Regional Investment Plan of the South Region 2017
As it can be seen, each country demand has a different variation on a seasonal ba-
sis which is mainly due to different share of the residential and commercial sector
(which represents more than half of the yearly demand in France as an example),
stressed by different climate conditions. On the other hand, the weekly modulation
is higher in Spain and Portugal, which is mainly due to Spain and Portugal both
using gas more for power generation and industry.
The gas demand for power generation in 2015 and in 2016 is shown in Figure 3.9.
It shows how the demand for power generation fluctuates a lot less with the seasons
compared to the conventional demand (shown in Figure 3.8). It also shows the huge
range found in the demand values explained by the role played by gas for power
generation in providing flexibility for the electrical system demand modulation, in
particular to deal with the intermittency of some renewable power generation (main-
ly for wind and solar sources).
