installed power capacity
The power plant is contained in a 240-metre-long and 77-metre-high reinforced concrete building. Its turbine hall houses eight generators, each rated at 82.8 MW. Since its commissioning, the plant has produced 234 bn kWh of electricity and an average of 3.8 TWh per year.
In 2019–2022 under the New Power modernisation program, the Group will replace three turbines and three generators at Irkutsk HPP to increase the installed capacity by 68.7 MW.
