The Central Communications Service under the President of the Republic of Kazakhstan held a briefing attended by Bakytzhan Kazhiyev, Chairman of KEGOC Management Board, on Electric Power Infrastructure as an Important Factor for Kazakhstan Economy Sustainable Development.
The company's executive told that in 2015 KEGOC as a System Operator ensured efficient and reliable operation of Kazakhstan Unified Power System (Kazakhstan UPS).
KEGOC's services on electricity transmission via interregional networks in 2015 amounted to 37.9 billion kWh. The services on technical dispatching of electricity transmission and consumption in 2015 made 82.8 billion kWh. The services on balancing electricity generation and consumption in 2015 amounted to 157 billion kWh.
Bakytzhan Kazhiyev marked that KEGOC established the Financial Settlement Centre for Support to Renewable Energy Sources (hereinafter referred to as the 'RSC') purchasing all the electricity generated by solar and wind power plants. In 2015 the FSC purchased more that 200 million kWh of the green energy totalling to KZT 5.5 billion. The figures are planned to be doubled in 2016.
Moving on to the main subject of our briefing I would like to recall that the Company is consistently working to achieve strategic goal on ensuring reliable and uninterrupted power supply for Kazakhstan consumers.
This is achieved in two areas: existing power facilities rehabilitation and new networks construction.
In the first area KEGOC has implemented (since 2000) such large-scale projects as the Kazakhstan Electricity Transmission Rehabilitation Project and the Kazakhstan Electricity Transmission Rehabilitation Project, Phase II. This facilitated efficient and sustainable operation of the power system, reduced the number of technical disturbances on substation equipment by more than four times and enhanced reliable and high-quality power supply for consumers.
In terms of new electric power infrastructure construction and establishment KEGOC constructed 500 kV second transmission line of Kazakhstan North–South transit, 500 kV Zhitikara – Ulke high-voltage line and 500 kV Alma SS connected to Kazakhstan NPG via 500, 220 kV transmission lines.
Currently, as instructed by the head of the state, KEGOC is implementing the largest-ever project on 500 kV North–East–South OHTL construction as part of the Nurly Zhol state programme. The project includes two phases.
Phase I: construction of 500 kV OHTL Ekibastuz–Semey–Ust-Kamenogorsk. The line commissioning will increase the North–East networks transmission capacity. East Kazakhstan Oblast consumers will directly receive Kazakhstan electricity and will not depend on the state of currently used Russian transit networks. In future this high-voltage line will deliver full power from the Irtysh HPP cascade.
Currently 520.8 km out of 600 km lines have been constructed of 500 kV OHTL Ekibastuz–Semey–Usk-Kamenogorsk. Regarding 220 kV OHTL Semey – Shulbinsk HPP with cross-connection lines to 500 kV Semey SS, 60.7 km out of the total length of 106 km have been built. The construction and erection works are also in progress at 500 kV Semey SS, 500 kV Ust–Kamenogorsk SS and 1150 kV Ekibastuz SS.
Phase II of the 500 kV Semey–Aktogai–Taldykorgan–Alma construction project has started this year. Upon completion this project will increase the NPG transit potential, cover the needs of electrified rail roads, energy intensive facilities of metal mining industry, create conditions for development of the cross-border territories and renewable sources (this being especially important as Kazakhstan is transiting to green economy) and strengthen the link with Zone East of the Kazakhstan Unified Power System.
The 500 kV North–East–South construction project is of a high social value. The overall construction period created 1,861 working places.
