KEGOC plans to complete, by the date of the 25th anniversary of Independence of Kazakhstan, the construction of the first phase of 500 kV North-East-South Electricity Transmission Project ahead of schedule, namely 500 kV OHTL Ekibastuz - Shulbinsk HPP (Semey) - Ust-Kamenogorsk.
This was stated today by Mr Umirzak Shukeyev, the Chairman of the Management Board of Samruk-Kazyna, during his visit to facilities that are being constructed under the 500 kV North-East-South Electricity Transmission Project in the East Kazakhstan Oblast. He also commended the progress of construction and thanked KEGOC and the contractors for the project's implementation quality.
KEGOC implements the 500 kV North-East-South Electricity Transmission Project under the 'Nurly Zhol - Path to the Future' Government programme, and the project consists of two phases: 500 kV Ekibastuz - Shulbinsk HPP (Semey) - Ust-Kamenogorsk Electricity Transmission Project (phase 1, scheduled for implementation: 2017) and 500 kV Shulbinsk HPP (Semey) - Aktogay - Taldykorgan - Alma Electricity Transmission Construction Project (phase 2, implementation: 2018.)
Mr Bakytzhan Kazhiyev, the Chairman of the Management Board of KEGOC, promised that all construction and erection works will be completed this autumn. After conducting a comprehensive testing of the equipment, the company plans to put 500 kV OHTL Ekibastuz – Shulbinsk HPP (Semey) – Ust-Kamenogorsk into operations in December 2016, which is one year earlier than the planned deadline.
- "This will be a significant gift from the Kazakhstani power engineers for the 25th anniversary of the Independence Day of the Republic of Kazakhstan," said the head of KEGOC.
The company has completed construction of more than 673 km of the planned 700 km of 500 kV and 220 kV transmission lines of the first phase including: 573 km of 500 kV lines and 100 km of 220 kV lines.
The construction is in progress at 500 kV Semey SS, 500 kV Ust-Kamenogorskaya SS and 1150 kV Ekibastuzskaya SS. Domestic reinforced concrete structures, metal towers, cables and wires, coupling capacitors, auxiliary transformers, etc. are used in construction.
- "I would like to emphasize the fact that the construction of the first phase of the project is conducted entirely at the expense of KEGOC's funds," - stressed Mr Bakhytzhan Kazhiyev.
Commissioning of the 500 kV OHTL Ekibastuz – Shulbinsk HPP (Semey) – Ust-Kamenogorsk will increase North - East transmission capacity of networks, cover deficits in the East Kazakhstan Oblast, regardless of the condition of the existing Russian networks that connect the East Kazakhstan Oblast with the power system of Kazakhstan, which is also important in the context of ensuring the energy security of the country. In future, this new transmission will be able to deliver full power from the cascading Irtysh HPPs.
According to Mr Bakhytzhan Kazhiyev, construction of the second phase of the North - East - South transmission project: 500 kV Shulbinsk HPP (Semey) - Aktogay - Taldykorgan - Alma Electricity Transmission Construction Project was launched this year. This second phase shall be completed in 2018.
In general, this large-scale 500 kV North-East-South Electricity Transmission Project, requires construction of over 1,700 km of 500 and 220 kV high voltage transmission lines (500 kV lines: 1,500 km and 220 kV lines: 200 km) and three 500 kV substations: Semey, Aktogai and Taldykorgan. Also 1150 kV Ekibastuzskaya SS, 500 kV Alma SS, 500 kV Ust-Kamenogorskaya SS, and 220 kV OSG of Shulbinsk HPP will be extended.
Completion of the second phase of the project will increase North-South transmission capacity of the National Power Grid (NPG) of Kazakhstan, power the 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 project has a great social importance. The construction will create 1,861 jobs.
KEGOC's plan to complete the construction of the first phase of the high-voltage transmission line in 2016 is well-considered and real. The company has strong experience in implementing projects in the power sector.
This is confirmed by the systematic and successful implementation of the long-term strategy of development of the National Power Grid by KEGOC.
In 2009, KEGOC has completed two major infrastructure projects: 500 kV second transmission line of Kazakhstan North–South transit, and 500 kV Zhitikara – Ulke transmission line.
The second transmission line of 500 kV North-South transit has doubled the capacity to transmit electricity to the south of the country from 600 MW to 1,259 MW and provided a solution to the acute shortage of electricity in the south of Kazakhstan. Construction of Zhitikara – Ulke transmission line (connects Aktobe and Kostanai Oblasts) has solved the issue of acute shortage of Kazakhstan's electricity in Aktobe power centre, ensured the independence of the region customers from the electricity supplies from Russia. For the first time in the electric power industry the project was implemented on the basis of the concession agreement.
Another major project was successfully completed in 2014, it was the Alma Electricity Transmission Project. Alma substation is the first 500 kV substation that was constructed in the independent Kazakhstan, for all previous projects only required the expansion of the existing 500 kV substations. The substation significantly increased the reliability of electricity supply to consumers of Almaty city and Almaty Oblast, provided the conditions for the development of the region, and, as a whole, created conditions for improving the reliability of power supply of the entire southern region of the country.
KEGOC has also completed the rehabilitation of equipment of the national power grid. This task has been achieved through the implementation of large-scale projects: the Kazakhstan Electricity Transmission Rehabilitation Project and the Kazakhstan Electricity Transmission Rehabilitation Project, Phase II. The following primary equipment was replaced under these projects: power transformers, reactors, switching devices, measuring current and voltage transformers, etc. As a result, it has provided effective and stable operation of the power system, reduced the number of technological disruptions at substation equipment by more than four times, increased reliability and quality of electricity supply to consumers.
It is important that all KEGOC projects have been implemented using the most modern technology and equipment, such as controlled shunt reactors, gas-insulated and vacuum circuit breakers, phase shifting transformers, microprocessor-based relay protection devices, and supervisory control and data acquisition (SCADA) system. These technologies shall also facilitate achieving the strategic goals of innovation and technological development of the company: create an active-adaptive national power grid (Smart Grid Technology), which will become the core of the smart grid of Kazakhstan.
