Overview of Siberian Hydro Power Environment • The Siberian federal district is one of the main industrial regions in Russia with a focus on oil and gas, metallurgy and engineering, and contributes approximately 10% of Russia's total GDP • A unique feature of the Siberian Integrated Power System (IPS) is the significant role of HPPs in both the structure of installed electricity capacity and electricity output - 49% and 57%, respectively • In the Siberian IPS zone, electricity spot prices are determined by the production costs of the least efficient coal-fired generation plant, with HPPs acting as price takers One of the major factors that exerts significant influence on price in the medium term is the water inflow to Siberian HPPs, which determines the availability of low-cost hydro power for the wholesale market Capacity structure in the Siberian price zone in Russia SPP 0.6% Competitive landscape Installed capacity in 2020 (GW) 18.9 Ent GROUP CHP 50.9% HPP 48.5% 12.3 15.0 3.9 Ent СИБИРСКАЯ ГЕНЕРИРУЮЩАЯ КОМПАНИЯ 7.2 3.9 3.0 RusHydro Thermal ■ Hydro INTER RAOUES GUMO 2 БОГУЧАНСКАЯ ГЭС En+ Group accounts for a 38.8% power market share in Siberia by total installed capacity, while UC RUSAL aluminum production is an important contributor to power demand Source: En+ Group, Companies' public finilings, System Operator, SEEPX Energy, Rosstat.
