The leading company in the modernization of electric power complex
Sustainable development of Kazakhstan’s electric power sphere, ensuring stable growth of capacities, is the key tasks for Kazakhstan in the long term. Further steady progress of the economy, expansion of opportunities for exports of electricity and effective satisfaction of domestic needs of both business and population highly depend on it. A special place here is given to the level of development of electric power infrastructure. Strengthening of this direction is seen as strategically important priority for Kazakhstan. Operations of such companies as «Promstroy-Energo» is of great importance in achieving that task.
Since its establishment in 2003, the company has successfully implemented a number of major projects in the electricity sector, including the expansion of 500 kV YuKGRES substation, construction of 500 kV «Shu» substation and others. This allowed the «Promstroy-En-ergo» LLP to create the image of effectively operating and responsible company – a brand extremely important in conditions of market competition.
In general, the activity of «Promstroy-energo» LLP is associated with such complex and diverse works in terms of technology industry as a construction and reconstruction of power transmission lines (power lines) and 110, 220, 500 kV substations, repair, installation and commissioning of power equipment; construction of cable and fber-optic communication lines, reconstruction of equipment of relay protection and automatic of power transmission lines of substations, the most complex special operations.
The balanced structure of the company, technological capabilities and a professional, well-organized work collective allow company to implement the full range of tasks, often unique in their way, at the level of advanced standards.
In particular, the technical base of the company is a specialized, fully equipped mechanized unit, stationed in Karaganda. Successful completion of complex electric power projects is a good indicator of compliance of the company’s technical equipment with modern requirements, as well as receiving of ST RK ISO 9001-2001 Quality Management System Certifcate in 2005. Obtaining the Cer-tifcate of ISO was a sign of recognition of the fact that the company's activities are based on the leading national and international quality standards.
Over the last years «Promstroy-Energo» LLP entered the nationwide level of activity, carrying out high-tech installation and construction works on the entire territory of Kazakhstan.
Construction of 500 kV Second Transmission Line of Kazakhstan North-South Transit
In cooperation with «KEGOC» JSC, the national system operator of the unifed power system of the Republic of Kazakhstan, «Prom-stroy-Energo» LLP has taken part in such a large project as «Construction of 500 kV Second Transmission Line of Kazakhstan North-South Transit», carried out in accordance with the development program of electricity of the Republic of Kazakhstan until 2030. Its necessity was conditioned by increasing of electricity supply level of defcient southern regions of Kazakhstan due to increasing of the output capacity of energy transmission in North-South direction up to 7-7.5 billion kWh per year, reliability and safety of the national electricity network of Kazakhstan, the parallel operation of power associations in Russia, Kazakhstan and Central Asia.
Thus, in the course of the project, the company completed the expansion of the 1st stage of 500 kV YuKGRES substation in 2006. In particular, the enterprise had carried out the installation of 500 kV GL317 gas-insulated circuit breaker in chain of shunt reactor R-3, the installation of three 500 KV BS, installation of control and power cables, cable trays, installation of F6-4 foundations for line portal. The next step of the company's involvement in this project was the construction of the 1st and 2nd stage of 500 kV «Shu» substation in Zhambyl oblast of Kazakhstan. The construction of substation with the installation of 500 kV shunt uncontrollable reactor and 500/220 kV auto-transformer, as well as installation of 220 kV and 500 kV cells were done. Drawing on extensive experience of construction, «Promstroy-Energo» has completed the expansion project of 1150 kV «Ekibastuz» substation in the Pavlodar region in 2009. In the same year the company held a reconstruction of relay protection and automatics (RPA) of this substation, including the supply of equipment and cable-wire products, installing the power switchboard cabinets of DC power and laying fberoptic cables. On September, 17 of that year the second Kazakhstan North-South Transit was launched on the 1150 kV «Ekibastuz» substation with participation of President Nursultan Nazarbayev.
The «North Kazakhstan-Aktobe oblast» project
Another major project with the contracting participation of «Promstroy-Energo» LLP was the construction of 500 kV «North Kazakhstan-Aktobe oblast» interregional power transmission line in Aktobe and Kostanai regions worth 19.9 billion tenge. Commissioning of the interregional power transmission line linking the North Kazakhstan with Aktobe region, in addition to solving the problem of the growing shortage of electric power in Aktobe region, made it possible to improve the reliability of electricity supply to consumers and reduce energy dependence of the Aktobe region consumers on supplies of expensive electricity from the Russian Federation.
The project customer, allowing the connection of Aktobe energy unit with a single power grid of Kazakhstan, is «Batys Transit». «Promstroy-Energo» during project implementation has built a 486 km long, 500 kV high-voltage line with «Ulke» and «Zhitikara» substations including fber-optic communication line.
It is noteworthy that for the frst time in the CIS «Promstroy-Energo» LLP had installed on the «Ulke» SS 220/220 kV three-phase, phase turnable transformer of forced fow distribution with capacity of 400 MVA, designed and constructed specifcally for this project.
Also, «Promstroy-Energo» has carried out con-struction of objects of external power supply of «Varvarinskoye» joint venture in Kostanai region, commissioned by «AREVA T & D Kazakhstan» LLP.
This project laid in construction of 110/10 kV «Barbara» substation with the installation of two transformers of TDN-16000/110-U1 and KRUN 10 kV, along with the reconstruction of the 220/110/10 kV «Lisakovskaya» substation. The Company participated in the replacement of high voltage equipment and the rebuilding of AL calls on substations of «KEGOC» JSC, among them the central TEN in Karaganda region (2004-05), Sarbaisky TENs in Kostanay region (2004-05), Akmola TEN in Akmola oblast (2006 year).
Construction of Koksairan counterregulator
Signifcantly, that in 2009 «Promstroy-Energo», commissioned by «Seldenkorgau Kurylys» RSCE, successfully implemented the investment project for the construction of food con-trol – Koksaray counter-regulator on the Syr Darya river.
In particular, the company carried out excavation works of 300 thousand cubic meters, the construction of outlet channel of 500 m long, and the construction of a 800 meters long dam. Design capacity of counter-regulator is about 3 billion cubic meters of water, thereby the threat of fooding territory of South Kazakhstan and Kyzylorda oblasts was reduced, and an irrigation water reserve for the agricultural sector was created. Rates of construction of this building are unprecedented. The frst test was already passed with a facility. In the food period this year it was managed to accumulate more than 900 million cubic meters of water and provide food safety of South Kazakhstan and Kyzylorda regions with the help of Koksaray counter-regulator. Also it has been made a discharge of the accumulated food water through the construction of water discharge counter-regulator into the Syr Darya river to fll the Aral Sea. These tests demonstrated the high quality of engineering and construction works carried out by the company as one of the main building contractors of counter-regulator. In general, the «Promstroy-Energo» LLP demonstrates high effciency indicators and reliability, as evidenced by large-scale projects, that characterized by the complexity of implementation. Certainly, this is a guarantee of company’s future success in creation of effectively operating and advanced electricity infrastructure of Kazakhstan.
