Zusammenfassung:	A method and a switching device for selectively operating a domestic appliance on a public mains grid of a public utility company and a decentralized mains grid associated with the building in which the at least one domestic appliance is operated. The decentralized mains grid can feed power to the public mains grid at a feed tariff. The domestic appliance is powered either from the public mains grid or from the decentralized mains grid depending on a comparison between the tariff from the public mains grid with the feed tariff, wherein the mains grid having a sustained lower consumption tariff than the other mains grid is selected. A domestic appliance having the switching device for selectively connection to a public mains grid and to a decentralized mains grid is also disclosed.
