Our network consists of more than 41,000 km 0.4 – 500 kV power lines and over 9,000 substations with total transformer capacity of over 27,000 MVA. Running one of the largest regional electrical grid systems in Russia for more than a decade has allowed us to increase the grid’s efficiency, reliability and resilience, making it less vulnerable to weather-related outages. Through this system, the Group transmits the electricity generated at the Angara cascade HPPs to wholesale and retail consumers, including RUSAL’s aluminium smelters.
Despite severe weather conditions in Siberia we are Russia’s #1 grid company in terms of overall reliability of performance (SAIDI). We continue to develop a smarter grid to ensure more reliable supply and greater utilization of electricity flow.
