Quick Answer
The world's first nuclear power plant to supply electricity to a power grid was at Obninsk, near Moscow, which began doing so on 27 June 1954.
The Full Story
The Obninsk plant in the Soviet Union had a small reactor producing about 5 megawatts of electricity. Earlier, in December 1951, the Experimental Breeder Reactor I in Idaho had generated the first electricity from nuclear power, enough to light four light bulbs. Obninsk, however, was the first to feed power into a grid for general use. Calder Hall in England, opened in 1956, became the first nuclear station to generate electricity on a commercial scale. Obninsk operated until 2002.
