An integrated coal gasification combined cycle facility is provided that can prevent a reduction in power generation efficiency even when low-grade coal having a relatively-high moisture content is used. Included are: a gasification section (3) that gasifies supplied coal; a gas power generation section (4) that generates power by using gas supplied from the gasification section (3); a steam power generation section (5) that generates power by using the heat of exhaust gas discharged from the gas power generation section (4); and a coal drying unit (15) that dries the coal by using exhaust heat discharged from the steam power generation section (5) and that supplies the dried coal to the gasification section (3).
