3.3.2 Forecast peak daily demand
Daily peak demand is of vital importance, as it is the main criterion for network
design. The chart below shows the historical Regional aggregated peak demand
over the last 4 years. This demand is the sum of national peak demand days during
the last four years that may have occurred on different days in each country. The
tables below show the comparison between the Southern Corridor GRIP 2014–2023,
and Southern Corridor GRIP 2017– 2026 data. It results that the forecasted peak
demand has been reassessed in the two consecutive investment plans, following the
trend of the average demand established in the last years.
Peak demand forecasts show a decrease consistent with annual demand revisions,
but their contractions are relatively less important as the percentage decreases of
peak demand are about half of the corresponding reductions of the total demand.
This means that the gas infrastructures are still key and necessary for reasons of
security of supply and market integration as well as for supporting the increase of
the use of RES in the power production.
