Feb 1–18 2008 the plant fulfilled 101.9% of the plan producing 23mln KW more than planned for the period. Since the beginning of this year the plant has generated 3.457bln KWh – 102.2% of the plan.

Presently, unit 1 is operating at a capacity of 1021MW.

Unit 2 is operating at a capacity of 1028MW.

Unit 3 is under repair. The maintenance personnel are presently completing the repair its turbine generators 5 and 6.

The life of the 1st unit has been extended for 15 years, the life of the 2nd unit — for five years (after the current modernization it will be extended for 15 more years). The service periods of 3rd and 4th units expire in 2009 and 2011, respectively. Their lives will be extended for 20 years.

In 2007 Leningrad NPP generated 24.633bln KWh and supplied to consumers 22.515bln KWh against 23.178bln KWh and 21.198bln KWh, respectively, in 2006. In 2007 the capacity factor made up 70.3% against 66.2% in 2006.
