The Leningrad Nuclear Power Plant is a branch of the Russian Concern for Production of Electric and Thermal Energy at Nuclear Power Plants («Rosenergoatom» JSC).
The Leningrad NPP is the country's first plant with RBMK-1000 reactors (high-power channel reactor). The Leningrad NPP uses boiling-type channel graphite-moderated water-cooled reactors.
The Leningrad NPP includes four power units. The electric capacity of one power unit is 1000 MW, and the thermal capacity is 3200 MW. The design output is 28 billion kWh per year. The plant use about 8% of the generated electricity. The design life of each power unit was set 30 years, but after large-scale upgrade, the useful life was extended by 15 years in accordance with the licenses obtained from Rostekhnadzor for each of four power units: that of Power Unit 1 – until 2018, Power Unit 2 – until 2020, Power Units 3 and 4 – until 2025.
The Leningrad NPP is the largest electricity producer in the North-West of Russia. The power plant supplies over 50% of the energy consumption of St. Petersburg and the Leningrad Region. In the fuel and energy balance of the entire North-West region, the power generated by the Leningrad NPP accounts for about 28%.
