Additionally there are preparations to temporarily suspend noise/pollution legislation that forbids backup power generators to run for more than 50 hours a year [0]. While the current idea is to only exempt sites (around 300 sites, 250 MW installed capacity) that are already used by SwissGrid for Ancillary Services [1], there is political pressure to temporarily include all sites with installed backup power generators (> 4 GW).

If even a fraction of this installed capacity would run in times of shortages, this should further reduce demand without causing disruption on industrial production or even having to schedule rolling blackouts.
