2.5.2.2 High demand cases
Reflecting the yearly volume data, Slow Progression and Blue Transition peak day
gas demand for power generation decrease and increase the most respectively. The
key differences lie in the Green scenarios, where the reduction between 2030 and
2035 is not as pronounced due to the requirement for providing generation in peak
times that coincide with low RES generation. Back-up to the variability of RES is a
key strength of gas-fired power plants.

Figure 2.32:
Peak gas demand for power generation
The 2-week high demand case follows the same trends displayed by the peak day,
but shows a greater variance between the values depending on the scenario, with
Slow Progression stable around 18–19%, but Blue Transition moving from a 22%
down to a 16% difference between values in 2035.
