KEGOC completed the largest infrastructure project in the power sector - North-East-South 500 kV Electricity Transmission Construction Project


On 11 December 2018, the President of Kazakhstan, Nursultan Nazarbayev, commissioned high-voltage 500 kV Shulbinskaya HPP (Semey) - Aktogai - Taldykorgan - Alma overhead transmission lines by giving a go to the KEGOC's CEO, Bakytzhan Kazhiyev during the live national teleconference, which was held as part of the Industrialization Day.

The construction of these lines is the second stage of the large-scale investment project named  North-East-South 500 kV Electricity Transmission Construction Project. Stage one, construction of 500 kV Ekibastuz - Shulbinsk HPP (Semey) - Ust-Kamenogorsk electricity transmission lines, was also put into operation also during the teleconference on 6 December 2016 with the participation of the Head of State.

Thus, KEGOC fully completed the largest infrastructure project in the industry, the construction of which started in 2014.

For four years KEGOC constructed more than 1,700 km of lines and three new 500 kV substations: Semey, Aktogay, and Taldykorgan. Open switchgears were expanded at 1150 kV Ekibastuzskaya substation, 500 kV Ust-Kamenogorsk substation, and 220 kV Shulbinskaya hydropower plant. 500 kV YuKGRES substation was expanded and rehabilitated.

The project has a significant multiplier effect. The construction project extensively used equipment and materials produced by domestic manufacturers: reinforced concrete products, metal towers, cables, coupling capacitors, voltage transformers, auxiliary transformers, and relay protection and automation panels.

Completion of this project has increased the transmission capacity from the northern power plants to the southern regions of Kazakhstan from 1,450 MW to 2,100 MW. The new line will also strengthen the electricity link with the East Kazakhstan region, which until has been supplied with power through the lines located on the territory of Russia. It will also cover electricity demand of electrified railways and energy-intensive mining facilities.

It is also important that the commissioning of this project will give impetus to the development of renewable energy sources, in particular, small hydropower plants.

Equally important is the social component of the project. The project created more than 1,800 jobs during construction period, and 84 permanent jobs for its operation.
