For determining the minimum start-up load and the minimum shut-down load for stable generation, at least three criteria shall be defined, with the end of start-up or start of shut-down periods reached when at least two of the criteria have been met.
These criteria shall be chosen from the following:
discrete processes set out in the Annex or equivalent processes that suit the technical characteristics of the plant;
thresholds for the operational parameters set out in the Annex, or equivalent operational parameters that suit the technical characteristics of the plant.
