In 2018 KEGOC 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 1,150 kV Ekibastuzskaya substation, 500 kV Ust-Kamenogorsk substation, and 220 kV Shulbinskaya HPP OSG. 500 kV Alma substation was expanded and rehabilitated.
On 11 December 2018, the First President of Kazakhstan, Nursultan Nazarbayev, commissioned high-voltage 500 kV Shulbinskaya HPP (Semey) – Aktogai – Taldykorgan – Alma overhead transmission lines (second stage) by giving a go to KEGOC’s CEO, Bakytzhan Kazhiyev during the live national teleconference, which was held as part of the Industrialization Day.
Stage one, construction of 500 kV Ekibastuz – Shulbinsk HPP (Semey) – Ust-Kamenogorsk electricity transmission lines, was also put into operation during the teleconference on 6 December 2016.
The Yelbassy stressed the high importance of the project providing Taldykorgan and Almaty with electricity through East Kazakhstan.
The construction project extensively used equipment and materials produced by domestic manufacturers.
Implementation of this project increased the transmission capacity from the northern power plants to the southern regions of Kazakhstan from 1,450 MW to 2,100 MW.
The commissioning of this East electricity transmission project will give impetus to the development of renewable energy sources, in particular, small hydropower plants.
The project construction created more than 1,800 jobs during construction period, and 84 permanent jobs for its operation.
Ekibastuz – Shulbinsk HPP (Semey) –
The aim of the 500 kV Ekibastuz – Shulbinsk HPP (Semey) – Ust-Kamenogorsk Electricity Transmission Project is to increase transmission capacity of the grid in North – East direction, cover deficits in the East Kazakhstan region by making it independent of the electricity transported through the Russian network, and ensure delivery of all power generated at Shulbinsk HPP after Bulak HPP, the counter regulator of Shulbinsk HPP, is put into operation.
Project implementation period
Shulbinsk HPP (Semey) – Aktogai –
Taldykorgan – Alma Electricity
500 kV OHTL Shulbinsk HPP (Semey) –Aktogay – Taldykorgan – Alma Construction Project shall increase the transmission capacity of the national power grid in North-South direction, cover the consumption of electrified railways, energy intensive facilities of metal mining industry, create conditions for development of the cross-border territories and large scale development of renewable energy potential and strengthen the link with Zone East of the Kazakhstan Unified Power System.
