1992
The beginning of the history of COTES. The commissioning company COTES was founded on October 13, 1992. Its co-founders included OAO ZiO, OAO Sibenergomash, the foreign trade association Teсhnopromexport, and the commissioning company Sibteсhenergo. Felix Serant became one of the founders and CEO of the company.

1993-1996
ГThe fledgling and developing years under the guidance of Felix Serant. One of the first projects was implemented at the Tunçbilek power plant in Turkey. Despite a general recession in the Russian power industry, the management of the company succeeded in doing their best to retain the key experts within the company. COTES was actively involved in projects in the following countries overseas: India, Cuba, Bulgaria, Poland, Serbia, Romania and China.

1997-2001
COTES entered the Kazakh market: the first projects were implemented in the power plants (GRES) in Ekibastuz. New business lines came into being such as turbine equipment commissioning and the uptake of distributed control systems for production processes. The Company implemented projects at large facilities throughout Russia (Berezovskaya GRES-1, Yuzhno-Kuzbasskaya GRES, Norilskaya CHP-1 plant), and continued its work abroad in Bosnia, Macedonia, Serbia, and Romania. An industrial prototype of a circular furnace boiler, Е-820, was successfully commissioned in the Novo-Irkutskaya CHP plant in 1997. In 2001, the Research and Development Board of RAO UES of Russia recommended the circular furnace boiler for commercial operation. Today, this unique octahedral furnace chamber design takes pride of place in the centre of the COTES logo, it has become the symbol of all the companies of the COTES Group.

2002-2003
Overseas projects still dominate the available stock of orders: The largest projects were implemented by COTES at the Skawina TPP in Poland, Obrenovac TPP, Ugljevik TPP, Gacko TPP and Kostolac TPP in the former Yugoslavia. Many projects were implemented within Russia as well in the power plants owned by Kuzbassenergo, Tomskenergo, and Irkutskenergo. In April 2003, an Agreement was signed between Novosibirskenergo and ZAO SibCOTES stating that the company was appointed as the General Designer of Novosibirskenergo. The COTES Group of companies started to actively develop a new business line, namely civil engineering.

2004-2006
The years of rapid development and growth of the COTES Group. Dozens of large projects were implemented simultaneously both in Russia and abroad in Poland, Romania, Macedonia, Kazakhstan, Bulgaria, and Morocco. There were several large commissions, including the startup of a turbine at the Novosibirsk CHP-3 plant and the 200 MW coal-fired power unit at the Novosibirsk CHP-5 plant. ZAO SibCOTES acted as an EPC Contractor in a project for the construction of a boiler house for the Chkalov Aircraft Production Association.

2007-2008
In 2007, the COTES Group of companies its 15th anniversary. The analysis elicited that, over 15 years, engineers from COTES had completed over 300 design projects, more than 250 projects in automation, over 200 commissioning projects, 76 financial and preliminary feasibility studies, as well as 41 integrated projects. In 2007, several large-scale projects were commissioned at once, namely the comprehensive design, commissioning and installation of APCS peak redundancy equipment within the boiler house of OAO Tomskenergo. The Teplovaya-2 substation in the Zheleznodorozhny district of Novosibirsk was built per COTES’ design. In June 2007, COTES as an EPC Contractor, completed the installation and commissioning of a new boiler at Mechel’s CHP plant.

2009-2010
The COTES Group was actively involved in projects in Kazakhstan: It developed the design for the rehabilitation of power unit No.8 at the Ekibastuzskaya GRES-1, implemented a number of projects for 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 by November, Gosekspertiza (the 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 Reftinskaya GRES got under way. A great amount of work on the design of motor car dealership centers and other projects was performed by the Civil Engineering Division of COTES.

2011-2012
Together with the Finnish company Pöyry, a project for the relocation of a 600 MW CCPP construction to a new site in Moscow was developed. Under contract with major energy companies – Inter RAO, RAO UES of East, Fortum – COTES designed three large combined-cycle power plants at once in Chelyabinsk, Nizhny Novgorod and Ufa. Several pre-feasibility studies were completed; upgrading 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 were dynamically implemented in Kazakhstan such as at the 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. A 500 MW unit for Ekibastuzskaya GRES-2 is under design; commissioning works at Karagandinskaya CHP-3 plant are commenced.

2013-2014
COTES is developing large CCPP projects: 3 combined-cycle power units, 250 MW each, for Chelyabinskaya GRES; 900 MW in Nizhny Novgorod; 440 MW combined-cycle power unit for Zatonskaya CHP plant in Ufa; design of the second 110 MW stage of a pulverized coal-fired unit for the Blagoveshchenskaya CHP plant. Professionals from COTES, together with an Italian company, Magaldi, implemented the first dry ash handling system for a 800 MW unit boiler at Berezovskaya GRES. In 2013, engineers from COTES successfully commissioned a distributed control system for a 300 MW unit at Ugljevik TPP. Together with the Chinese company SDEPCI, the COTES Group prepared a preliminary feasibility study of different construction options for the largest coal power plant – the 8 GW Erkovetskaya TPP. The feasibility study for the construction of a substitute energy source for the Azot Chemical Plant is developed. Together with Pöyry, a global consulting and engineering firm, COTES supervised the installation and commissioning of a newly built power units with CFB boilers at Narva power plant (Estonia).

2015-2016
Two CCPP units, 247.5 MW each, at Chelyabinskaya GRES were put into commercial operation. COTES prepared a preliminary feasibility study for the Rubtsovskaya CHP plant. For the Zatonskaya CHP-5 plant, COTES provided services for both the design and supply of a turbine unit’s vibration-isolating foundations. In 2015, COTES began adaptation of the operating documentation of the 1320 MW Balkhashskaya CHP plant. Issue of the operating documentation had been resumed after conclusion of the power purchase agreement by Zatonskaya CHP plant. COTES started work on the design of the 195 MW Primorskaya CHP plant in Kaliningrad. The recommendation of InterRAO Scientific and Technical Council to consider the boiler in a design for all newly constructed and upgraded coal-fired plants owned by the holding, formed a solid step towards promotion of the circular furnace boiler.

2017
COTES professionals completed the water chemistry monitoring system design for Ust-Ilimsk Pulp and Paper Mill boilers, as well as construction of packaged steam boiler houses for extra-heavy oil production in AO Tatneft. COTES audited four power plants belonging to Sibeco and Biyskenergo. COTES carried out pilot combustion of off-grade coal at the Vorkutinskaya CHP-2 plant, and performed an analysis followed by an issuing of recommendations for 7 boilers. COTES completed a project for Tsentralnaya CHP plant’s boilers being switched to reduced parameters in Novokuznetsk, and comprehensive current condition diagnostics of main and auxiliary equipment of the Yurginskaya CHP plant’s facilities. In December 2017, a successful startup of a new boiler house for PAO Tyazhstankogidropress was completed on a turnkey basis. In October 2017, COTES celebrated its 25th anniversary with best friends and partners being invited.
