Dies wird dadurch erreicht, dass die Feuerungsanlage temporär während ihrer Betriebszeit in einem Stand-By-Modus betrieben wird, in welchem sie in einem Mindestlastbereich oder Minimallastbereich des Dampferzeugers betrieben wird und dabei erzeugte, nicht in das ans Kraftwerk angeschlossene Stromnetz eingespeiste oder einzuspeisende Energie zur Aufbereitung von für den Betrieb des Kraftwerks benötigten Roh- oder Betriebsstoffen, insbesondere zum Betrieb der mindestens einen Kohlemühle, verwendet und/oder in mindestens einer, vorzugsweise ins Kraftwerk integrierten, Anlage gespeichert und/oder im Rahmen einer Kraft-Wärme-Kopplung genutzt wird.
