1.For combustion plants generating electricity and for combustion plants for mechanical drive, the start-up period shall be considered to end at the point when the plant reaches the minimum start-up load for stable generation.
2.The shut-down period shall be considered to begin at the initiation of termination of fuel supply after reaching the point of the minimum shut-down load for stable generation from where on generated electricity is no longer available for the grid or generated mechanical power is no longer useful for the mechanical load.
3.The load thresholds to be used for determining the end of the start-up period and the start of the shut-down period for electricity generating combustion plants and to be included in the plant’s permit shall be a fixed percentage of the rated electrical output of the combustion plant.
4.The load thresholds to be used for determining the end of the start-up period and the start of the shut-down period for combustion plant for mechanical drive and to be included in the plant’s permit shall be a fixed percentage of the mechanical power output of the combustion plant.
