The metals segment’s operations cover the extraction and refinement of bauxite into alumina as well as the production and sale of primary aluminium, alumina and related products. The segment’s core smelting operations are located in Siberia, in close proximity to the Group’s energy assets. 15 GW Boguchany HPP1 ~ Ust-Ilimsk HPP Angara river Krasnoyarsk Aluminium Smelter Boguchansk Aluminium Smelter KraMZ Bratsk HPP Bratsk Aluminium Smelter Krasnoyarsk HPP Taishet Aluminium Smelter Yenisey river Lake Baikal POWER segment Khakas Aluminium Smelter Irkutsk HPP En+ Group operates energy assets with 19.6 GW of installed electricity capacity, over 15 GW of which comes from low-carbon hydropower sources. These assets also include 15.0 kGcal/h of installed heat capacity. Three of En+ Group’s hydropower plants are among the largest 20 in the world (by installed capacity): Krasnoyarsk HPP (6,000 MW), Bratsk HPP (4,500 MW) and Ust-Ilimsk HPP (3,840 MW). Our Energy segment is investing in R&D including the development of new types of perovskite-based solar panels.
