The Leningrad Region power network was substantially reorganized in 1964. The 28 regional Selenergo agriculture energy operating divisions were liquidated and reorganized into eight Lenenergo power network divisions and agriculture electrification and distribution network services. Thus the Vyborgskiye, Gatchinskiye, Kingiseppskiye, Lodeynopolskiye, Luzhskiye, Novoladozhskiye, Prigorodnye and Tikhvinskiye power grids were created. The new companies provided power supplies to agriculture, industry and the population of the Leningrad Region. Over their first 20 years, 53,098 kilometres of 10 and 6 kV overhead networks and 31,822 kilometres of 0.5 kV networks were constructed, which doubled the coverage of the previous networks inherited from Selenergo.
