The minimum loading of the units in the steam plant I worked in was due to the minimum stability of one coal pulverizer of six; if the load was reduced too far, the air flow through the mill would become erratic and unstable, causing a boiler flame-out, which then required a furnace purge and re-ignition on oil.
