COTES Group implements large energy projects. In Kazakhstan the projects are under way for Ekibastuzskaya GRES-1 and Ekibastuzskaya GRES-2, Astaninskaya CHP-3 and CHP-2 plants, Karagandinskaya CHP-3 plant. Jointly with Pöyry (Finland), COTES develops the design for two CCPPs, 247.5 MW each, for the Chelyabinskaya GRES and the design for relocation of a 600 MW CCPP to a new site in Moscow. In September, the project for the construction of two CCPP units in Chelyabinsk received an approval from Glavgosexpertiza of Russia, and COTES started detailed design development. Several preliminary feasibility studies and financial feasibility studies were developed. The company continues its energetic efforts related to commissioning and comprehensive automation of power plants overseas: at Ugljevik TPP (Bosnia and Herzegovina) and Kostolac-A TPP (Serbia).

2009-2010

SibCOTES was renamed E4-SibCOTES, whereby it completed the process of its withdrawal from the COTES Group of companies.As from 2009, COTES Group and Е4-SibCOTES operate independently.

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 the year, design engineers from the Group started designing 500 MW power unit No.3 of the Ekibastuzskaya GRES-2, and already in November, Gosekspertiza (State Project Expertise Authority) approvedthe 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 is performed by the Civil Engineering Division of COTES.
