Global Leader in Hydro Power and Aluminium
Power Segment's HPP Modernisation Programs
Ent
GROUP
•
'New Energy' is an ongoing program, focused on modernising the power plants at
Angara and Yenisei cascades, to improve efficiency, reliability and safety as well as
reduce potential GHG emissions by augmented HPP generation
• As part of the program:
•
•
.
•
Ust-Ilimsk: 4 runners replaced
Krasnoyarsk: all 12 hydraulic units and 2 runners replaced
Bratsk: 12 out of 18 runners replaced
Irkutsk: upgrade began in July 2019. The new hydropower unit will be
commissioned no later than 1 July 2020. Under the modernisation
programme, 4 of the 8 hydropower units installed at the plant will be
replaced by 2023
Investment is expected to total RUB 21 bln in the period to 2026 (c. USD 339.2
million as of 31 December 2019), including funds already invested in the project¹
Modernised HPP turbines offer increased efficiency and better cavitation. From
2022 the Group's HPPs are expected to increase their clean electricity generation
by 2 TWh, from the same volume of water
The upgraded equipment delivered an increase in HPP energy production of 1.68
TWh in 2019 compared to the same periods last year, helping to reduce
greenhouse gas emissions by approximately 1,951 thousand tonnes of CO2e for
2019 due to partial replacement of prior CHP generation volumes
