Specifically, the group’s hydropower output increased to 28.7 TWh (up 9.1% year over year) in the first half of 2019 and to 14.6 TWh in the second quarter of 2019 (up 3.5% year over year).
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.
The “New Energy” hydropower plant modernization program, under which upgraded equipment allowed for increased energy production from the hydro plants of 325 GWh in the second quarter of 2019, amounting to 595 GWh in the first half of 2019.
The group commenced modernization of the Irkutsk plant on July 1, 2019, taking out of service a first unit. The new unit will be commissioned no later than July 1, 2020. Four of the eight units installed at the plant will be replaced by 2023, with the capacity of each unit expected to increase from 82.8 MW to 105.7 MW.
Related to the overall Russian energy market, En+ Group reported that electricity consumption remained broadly flat at 110.6 TWh (down 0.2% year over year) and the group generated about 33.1% of the total electricity produced in the Siberian integrated energy system. The group’s hydropower plants generated about 61.2% of the total electricity produced by hydropower stations in the Siberian integrated energy system.
