Electricity output of Irkutskenergo´s Ust-Ilimskaya HPP reaches 800 TWh on August 27, 2015


On August 27, 2015, at 4:42 p.m. local time, electricity output of the Ust-Ilimskaya HPP operated by Irkutskenergo (a company forming part of EuroSibEnergo Group) reached 800 TWh; thus, it became the third HPP in Russia to have reached this milestone. To generate the same amount of electricity at a CHPP, 249,040,000 tons of coal would be required; this can be visualized as a freight train that is 49,808 km long, which is 9,800 km longer than the Earth's equator; this amount of energy would be sufficient for supplying Ust-Ilimsk and its industrial enterprises for 641 years.

The Ust-Ilimskaya HPP is the third stage of the Angara Cascade of HPPs, the first two being the Irkutskaya and Bratskaya HPPs. Its construction started in 1963. In 1974 the Ust-Ilimsk reservoir started to be filled. Full-scale commercial operation of the power plant started in 1980. The HPP is equipped with 16 hydroelectric units comprising Francis turbines and umbrella-type generators. The Ust-Ilimskaya HPP has a rated capacity of 4,320 MW, and its installed capacity totals 3,840 MW. Its long-term annual average electricity output amounts to 21.7 TWh per year. Its guaranteed output totals 20.7 TWh, while the annual average capacity utilization amounts to 5,050 hours.

The total output of the Ust-Ilimskaya HPP reached 100 TWh in 1981, 200 TWh in 1986, 300 TWh in 1991, 400 TWh in 1995, 500 TWh in 2000, 600 TWh in 2005, and 700 TWh in 2010.

According to the CEO of PJSC Irkutskenergo Oleg Prichko, "800,000,000,000 is a round number that symbolizes the efforts of a large number of people: researchers, designers, construction workers, equipment manufacturers, operating and maintenance personnel. The Ust-Ilimskaya HPP has become a basis for the development of the entire Ust-Ilimsk Industrial Hub; it plays an important role in ensuring the reliability of the Siberian power system. High professionalism, experience and skill of all employees working at the power plant enable it to remain one of the best HPPs in Russia in terms of technical and economic performance."
