OGK-2 power plants generated 55.7 billion kWh in 2025, which is 3% less than a year earlier. The volume change is due to a decrease in demand for generating equipment during the reporting period. Heat output amounted to 4.93 million Gcal, a decrease of 5%. The main reason for the decrease in the indicator was a decrease in the consumption of thermal energy from Kirishskaya GRES.
