Project of Power Unit No. 3 at the Ekibastuzskaya GRES-2 Approved by State Expert Review Board

The experts thoroughly analyzed the technical documentation in all parts of the project during three months.
Technical solutions implanted in the design did not undergo considerable changes in the course of coordination and examination. According to the expert opinion, the design was elaborated in the required scope, in accordance with the project statement, initial data, specification and requirements. The design took into account local natural and climatic conditions and geological situation of the construction site. The design meets the requirements of the state standards of the Republic of Kazakhstan in respect of sanitary, ecological and industrial safety and functional specification of the project.
The project for expansion of a 500 MW Ekibastuzskaya GRES-2 is one of the top-priority investment projects within the power industry, which is of primary importance for stable development of both Russia and Kazakhstan. COTES was the General Designer of the project. COTES specialists jointly with subcontractors developed main engineering solutions and approval level design in five months. “Immense job was made by our design engineers in a very limited period of time,” says Dmitry Serant, COTES General Director. “In the course of cooperation with the experts, a number of issues were discussed relating to technical, economic and environmental aspects of the prospective power unit. All main engineering solutions, including those connected to present-day technologies were favorably evaluated by the experts and confirmed by appropriate decisions of the State Expert Review Board”.
The approved design provides for the state-of-the-art technologies for improved efficiency and environmental friendliness of the power plant operation. The advanced low-emission burners and staged combustion will ensure for decrease of NOX emissions in flue gases. These solutions were successfully tested and implemented at several plants abroad and proved their high efficiency. The new unit will be also equipped with an innovative desulfurization system which lowers SOx emissions to required levels. The main equipment of unit No. 3 will be similar to that operating at the two existing ones. Serious upgrading of boiler and turbine equipment is planned in order to raise the power unit efficiency. The unit will be furnished with a modern automation system. The design was made with the use of PDMS 3D design software.
Owing to the earliest possible launch of the new capacities in the North Kazakhstan and Siberia, the construction period of power unit No. 3 of the Ekibastuzskaya GRES-2 is strictly limited. Tenders for the main and auxiliary equipment supply are to be organized in the short run. The start-up of the power unit is scheduled for December 2013.
