New power is a programme modernising the power plants of the Angara and Yenisei HPP cascade to ramp up the energy output using the same water volume passing through the hydro power turbines.
Another of its objectives is to reduce environmental impact by curbing the greenhouse gas emissions of the Company’s coal-fired power plants. In 2019, the programme enabled En+ Group to ramp up its power output by 1.7 TWh. The programme was first launched in 2007 for the large-scale overhaul and replacement of the core equipment of the Company’s largest HPPs located in Siberia – Krasnoyarsk, Bratsk, Irkutsk, and UstIlimsk HPPs.
The programme entails the modernisation of hydroelectric generation units and replacement of runners, transformers, and open-type switchgear. Higher efficiency (max + 8%) will be provided by the new runners’ improved blades and utilising new materials. A higher level of safety and reliability of the HPPs is another priority of the modernisation, which will mitigate risks associated with cavitation and prevent the HPP generators from wearing out.
So far, 12 runners have been replaced at Bratsk HPP, 4 runners at Ust-Ilimsk HPP, 2 runners at Krasnoyarsk HPP, and a project to replace 3 generation units at Irkutsk HPP is underway.
