We discuss the super Higgs mechanism in four dimensional supergravity obtained by the gauging of a "flat group", an electric subgroup of the duality group. The Scherk-Schwarz mechanism of dimensional reduction is reinterpreted from a purely four dimensional point of view in this context. Compactifications in presence of brane fluxes also fall in this category.
