Overall, the group’s electricity production increased 5.4% year over year to 36.9 TWh.

Hydropower plants mentioned in the update include:

Krasnoyarsk, where total power generation decreased to 9.1 TWh in the first half of 2019 (down 9.0% year over year) and was 4.7 TWh in the second quarter (down 14.5% year over year). Lateral inflow to the Krasnoyarsk reservoir was 2,572 cms (86.3% of normal level) in the second quarter of 2019 compared to 3,104 cms (104.2% of normal level) in the same quarter of 2018.

The Angara cascade (Irkutsk, Bratsk and Ust-Ilimsk hydro plants) increased power generation to 19.6 TWh in the first half of 2019 (up 20.2% year over year) and to 9.9 TWh in the second quarter of 2019 (up 15.1% year over year) due to increased water reserves in the Angara cascade reservoirs.
