On March 22, 2021, VVER-1200 reactor-enabled Unit 6 was commissioned at the Leningrad NPP. Pilot operation with 15-day comprehensive tests preceded the unit’s commissioning. On March 10, following the tests, Russian nuclear watchdog Rostechnadzor confirmed the facility compliance with the design documentation, technical regulations, and energy efficiency requirements.

Leningrad NPP covers more than 55% of energy needs of St. Petersburg and Leningrad Region, which constitutes 30% of the electricity generation in the North-West of Russia. Despite the decommissioning of Unit 2, the Leningrad NPP with an installed capacity of 4,400 MW remains the most powerful nuclear power plant in Russia and the largest power plant in the North-West of Russia. Its VVER-1200 reactor-enabled units serve as references for a number of ROSATOM’s international NPP projects: Hanhikivi-1 NPP in Finland, Paks-2 NPP in Hungary, the Belarusian NPP.

The installed capacity of Leningrad NPP is 4,400 MW. By the start of its commercial operation, Leningrad NPP Unit 6 had already generated about 2 billion kWh of electricity. According to preliminary estimates, after the beginning of commercial operation, the economic effect in the form of additional taxes to the consolidated budget of the Leningrad Region will amount to more than 3 billion rubles (nearly 40,5 million dollars) annually.
