KAZENERGY MEMBERS«Promstroy-Energo» LLP:efficiency and reliabilityThe leading company in themodernization of electric power complexSustainable development of Kazakhstan’selectric power sphere, ensuring stable growthof capacities, is the key tasks for Kazakhstanin the long term. Further steady progress ofthe economy, expansion of opportunities forexports of electricity and effective satisfactionof domestic needs of both business and populationhighly depend on it.A special place here is given to the level ofdevelopment of electric power infrastructure.Strengthening of this direction is seen as strategicallyimportant priority for Kazakhstan.Operations of such companies as «Promstroy-Energo» is of great importance in achievingthat task.Since its establishment in 2003, the companyhas successfully implemented a number of majorprojects in the electricity sector, includingthe expansion of 500 kV YuKGRES substation,construction of 500 kV «Shu» substationand others. This allowed the «Promstroy-Energo»LLP to create the image of effectivelyoperating and responsible company – a brandextremely important in conditions of marketcompetition.In general, the activity of «Promstroy-energo»LLP is associated with such complex and diverseworks in terms of technology industryas a construction and reconstruction of powertransmission lines (power lines) and 110, 220,500 kV substations, repair, installation andcommissioning of power equipment; constructionof cable and fiber-optic communicationlines, reconstruction of equipment of relay protectionand automatic of power transmissionlines of substations, the most complex specialoperations.The balanced structure of the company, technologicalcapabilities and a professional,well-organized work collective allow companyto implement the full range of tasks, oftenunique in their way, at the level of advancedstandards.In particular, the technical base of the companyis a specialized, fully equipped mechanizedunit, stationed in Karaganda.Successful completion of complex electric powerprojects is a good indicator of complianceof the company’s technical equipment withmodern requirements, as well as receiving ofST RK ISO 9001-2001 Quality ManagementSystem Certificate in 2005. Obtaining the Certificateof ISO was a sign of recognition of thefact that the company's activities are based onthe leading national and international qualitystandards.Over the last years «Promstroy-Energo» LLPentered the nationwide level of activity, carryingout high-tech installation and constructionworks on the entire territory of Kazakhstan.Construction of 500 kV Second TransmissionLine of Kazakhstan North-South TransitIn cooperation with «KEGOC» JSC, the nationalsystem operator of the unified powersystem of the Republic of Kazakhstan, «Promstroy-Energo»LLP has taken part in such alarge project as «Construction of 500 kV SecondTransmission Line of Kazakhstan North-South Transit», carried out in accordance withthe development program of electricity of theRepublic of Kazakhstan until 2030.Its necessity was conditioned by increasing ofelectricity supply level of deficient southernregions of Kazakhstan due to increasing ofthe output capacity of energy transmission inNorth-South direction up to 7-7.5 billion kWhper year, reliability and safety of the nationalelectricity network of Kazakhstan, the paralleloperation of power associations in Russia,Kazakhstan and Central Asia.80 № 5 (<strong>49</strong>), <strong>2011</strong>
Thus, in the course of the project, the companycompleted the expansion of the 1st stage of500 kV YuKGRES substation in 2006.In particular, the enterprise had carried outthe installation of 500 kV GL317 gas-insulatedcircuit breaker in chain of shunt reactor R-3,the installation of three 500 KV BS, installationof control and power cables, cable trays,installation of F6-4 foundations for line portal.The next step of the company's involvementin this project was the construction of the 1stand 2nd stage of 500 kV «Shu» substation inZhambyl oblast of Kazakhstan. The constructionof substation with the installation of 500kV shunt uncontrollable reactor and 500/220kV auto-transformer, as well as installation of220 kV and 500 kV cells were done.Drawing on extensive experience of construction,«Promstroy-Energo» has completed theexpansion project of 1150 kV «Ekibastuz» substationin the Pavlodar region in 2009. In thesame year the company held a reconstructionof relay protection and automatics (RPA) ofthis substation, including the supply of equipmentand cable-wire products, installing thepower switchboard cabinets of DC power andlaying fiber-optic cables.On September, 17 of that year the second KazakhstanNorth-South Transit was launchedon the 1150 kV «Ekibastuz» substation withparticipation of President Nursultan Nazarbayev.The «North Kazakhstan-Aktobe oblast»projectAnother major project with the contractingparticipation of «Promstroy-Energo» LLPwas the construction of 500 kV «North Kazakhstan-Aktobeoblast» inter-regional powertransmission line in Aktobe and Kostanai regionsworth 19.9 billion tenge.Commissioning of the interregional powertransmission line linking the North Kazakhstanwith Aktobe region, in addition to solvingthe problem of the growing shortage of electricpower in Aktobe region, made it possibleto improve the reliability of electricity supplyto consumers and reduce energy dependenceof the Aktobe region consumers on supplies ofexpensive electricity from the Russian Federation.The project customer, allowing the connectionof Aktobe energy unit with a single power gridof Kazakhstan, is «Batys Transit».«Promstroy-Energo» during project implementationhas built a 486 km long, 500 kV highvoltageline with «Ulke» and «Zhitikara» substationsincluding fiber-optic communicationline.It is noteworthy that for the first time in theCIS «Promstroy-Energo» LLP had installed onthe «Ulke» SS 220/220 kV three-phase, phaseturnable transformer of forced flow distributionwith capacity of 400 MVA, designed andconstructed specifically for this project.Also, «Promstroy-Energo» has carried out constructionof objects of external power supplyof «Varvarinskoye» joint venture in Kostanairegion, commissioned by «AREVA T & D Kazakhstan»LLP.This project laid in construction of 110/10 kV«Barbara» substation with the installation oftwo transformers of TDN-16000/110-U1 andKRUN 10 kV, along with the reconstruction ofthe 220/110/10 kV «Lisakovskaya» substation.The Company participated in the replacementof high voltage equipment and the rebuildingof AL calls on substations of «KEGOC»JSC, among them the central TEN in Karagandaregion (2004-05), Sarbaisky TENs inKostanay region (2004-05), Akmola TEN inAkmola oblast (2006 year).Construction of KoksairancounterregulatorSignificantly, that in 2009 «Promstroy-Energo»,commissioned by «Seldenkorgau Kurylys»RSCE, successfully implemented the investmentproject for the construction of flood control– Koksaray counter-regulator on the SyrDarya river.In particular, the company carried out excavationworks of 300 thousand cubic meters, theconstruction of outlet channel of 500 m long,and the construction of a 800 meters long dam.Design capacity of counter-regulator is about3 billion cubic meters of water, thereby thethreat of flooding territory of South Kazakhstanand Kyzylorda oblasts was reduced, andan irrigation water reserve for the agriculturalsector was created. Rates of construction ofthis building are unprecedented.The first test was already passed with a facility.In the flood period this year it was managedto accumulate more than 900 millioncubic meters of water and provide flood safetyof South Kazakhstan and Kyzylorda regionswith the help of Koksaray counter-regulator.Also it has been made a discharge of the accumulatedflood water through the constructionof water discharge counter-regulator into theSyr Darya river to fill the Aral Sea.These tests demonstrated the high quality ofengineering and construction works carriedout by the company as one of the main buildingcontractors of counter-regulator. In general,the «Promstroy-Energo» LLP demonstrateshigh efficiency indicators and reliability, asevidenced by large-scale projects, that characterizedby the complexity of implementation.Certainly, this is a guarantee of company’s futuresuccess in creation of effectively operatingand advanced electricity infrastructure ofKazakhstan.Since itsestablishmentin 2003, thecompany hassuccessfullyimplemented anumber of majorprojects in theelectricity sector.KAZENERGY81
