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. Under the modernisation programme, 1 generation unit replaced in 2020 and 3 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 290.2 million as of 30 June 2021), 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 at the Group's Bratsk, Ust-Ilimsk, Irkutsk and Krasnoyarsk HPPs supported an increase in hydropower production of 936.3 GWh in 1H 2021, helping to prevent greenhouse gas emissions by approximately 1,085 thousand tonnes of CO2e due to the partial replacement of prior thermal power generation volumes (1) Calculated based on USD/RUB exchange rate 72.37 as of 30.06.2021. 50
