COTES Group implements several large projects simultaneously: 3 combined-cycle power units, 250 MW each, for the Chelyabinskaya GRES; two combined-cycle power units, 450 MW each, in Nizhny Novgorod; 440 MW combined-cycle power unit for the Zatonskaya CHP plant in Ufa; design of the second 110 MW stage of pulverized coal-fired unit for the Blagoveshchenskaya CHP plant. The professionals from COTES, together with an Italian company Magaldi, implement the first dry ash handling system for a 800 MW unit boiler at the Berezovskaya GRES. In 2013, the engineers from COTES successfully commission automated process control system for a 300 MW unit at the Ugljevik TPP Together with Chinese SDEPCI, COTES Group prepares preliminary feasibility study of different construction options for the largest coal power plant - 8 GW Erkovetskaya TPP. The feasibility study for the construction of a substitute energy source for Azot Chemical Plant is developed. Together with Pöyry, a global consulting and engineering firm, COTES supervises installation and commissioning of newly built power units with CFB boilers at the Narva power plant (Estonia).

2011 2012

2011-2012
Together with a Finnish company Pöyry, the project for relocation of 600 MW CCPP construction to a new site in Moscow is developed. Under the contract with the major energy companies - Inter RAO, RAO UES of East, Fortum - COTES designs three large combined-cycle power plants at once: in Chelyabinsk, Nizhny Novgorod and Ufa. Several pre-feasibility studies are completed: upgrading of unit No.7 at the Cherepetskaya GRES, TPP construction in Arkhangelsk Region, TPP construction at Ozerny Mining and Processing Complex, as well as for the Bishkek CHP plant expansion. Projects are dynamically implemented in Kazakhstan, namely, at Astaninskaya CHP-3 and CHP-2 plants , and Karagandinskaya CHP-3. Basic design for the rehabilitation and upgrading of power unit No.8 at Ekibastuzskaya GRES-1 is completed. 500 MW unit for Ekibastuzskaya GRES-2 is under design; commissioning works at Karagandinskaya CHP-3 plant are commenced.

2009-2010
COTES Group is actively involved in the projects in Kazakhstan: it develops the design for rehabilitation of power unit No.8 at the Ekibastuzskaya GRES-1, implements a number of projects for the Karagandinskaya CHP-3 and Astaninskaya CHP-2 plants. At the beginning of 2009, design engineers from COTES started designing 500 MW power unit No.3 of the Ekibastuzskaya GRES-2, and already in November, Gosekspertiza (State Expert Review Board) issued its Clear Opinion for the project. The project for the refurbishment of the firing system for a 300 MW power unit No.5 of the Reftinskaya GRES is under way. A great amount of work on design of motor car dealership centers and other projects is performed by the Civil Engineering Division of COTES.
