Key production assets

Generating facilities

Electricity and heat production is the key business of RusHydro Group. The Group’s asset structure includes over 70 renewable energy facilities, along with some thermal generation facilities and electrical grid assets in the Far East. As at January 1, 2020, the installed capacity of RusHydro Group’s power plants, including Boguchanskaya HPP, totaled 38,060 MWIncluding JSC Boguchanskaya HPP (a joint venture of PJSC RusHydro and RUSAL). The capacity reduction was mainly due to Primorskaya GRES ceasing to be part of RusHydro Group., down 1,623 MW year-on-year. The installed heat capacity declined to 18,839 Gcal/h, or by 182.2 Gcal/h.

Key changes in the installed capacity at RusHydro Group’s facilities were driven by the commissioning of Zaramagskaya HPP-1 (346 MW), Verkhnebalkarskaya SHPP (10 MW), Ust-Dzhegutinskaya SHPP (5.6 MW), Barsuchkovskaya SHPP (5.25 MW), CHPP in Sovetskaya Gavan (126 MW), sale of Primorskaya GRES (1,467 MW) and HPP in Armenia (561 MW), as well as the implementation of the Comprehensive Modernization Program at Rybinskaya HPP (+10 MW) and Votkinskaya HPP (+15 MW).

The installed capacity structure shows the prevalence of large HPPs generating 29,409 MWNot including PSPP and HPP-PSPP., or 77.3% of the total installed capacity, while 7,054.8 MW, or 18.5% of the installed capacity, is generated by the TPPs of RAO ES East Subgroup. The Group’s assets also include 1,200 MW Zagorskaya PSPP, 300 MW Zelenchukskaya HPP-PSPP and 15.9 MW Kubanskaya PSPP. The Group’s renewable energy facilities, including GeoPP, WPP and SPP, account for a total installed capacity of 80.76 MW.

Electric grid

RAO ES East Subgroup’s companies are responsible for power transmission and distribution both in UES of the East and in technologically isolated energy systems.

The changes in the length of transmission power lines (+ 0.8%) and the number (+1.2%) and capacity (+3.1%) of transformer substations are primarily associated with the commissioning of newly built facilities, signing of lease (repairs and maintenance) agreements for grid infrastructure facilities, utility connections to grids, and stock-taking of grid assets. Losses in grids were brought down to 9.64%.
