2.5 TYNDP Demand Data

The demand data represented here corresponds to the data submitted from TSO in accordance with the demand scenario storylines and parameters. Volume data represents average yearly demand and as such indicates non-climatic variations that would naturally occur. This input data for the TYNDP assessment was shared with stakeholders as part of an early transparency workshop, along with the supply production and projects submitted.

2.5.1 FINAL GAS DEMAND (RESIDENTIAL &

COMMERCIAL, INDUSTRIAL AND TRANSPORT) The following figures show the evolution of the final gas demand in the TYNDP assessment years for all scenarios, including sectoral data. This covers informa- tion regarding yearly average volume, as well as the high demand cases of the peak day (1-day Design Case, DC) and the 2-week high demand case (14-day Uniform Risk, 2W) average daily demand.

2.5.1.1 Volume

The scenario parameters have affected the EU28+ yearly final demand volumes in different ways to give a range of evolutions. In the Slow Progression scenario final gas demand is expected to marginally decline between 2017 and 2035 (-3.3%) as the poor economic conditions and green ambi- tion see little growth or decarbonisation, but some energy efficiency would still be expected. Blue Transition volumes remains almost completely stable across the time period, as increased demand from transport and industrial sectors balance reductions in the residential and commercial sector driven by moderate efficiencies and green technology developments.
