Tikhvin Carriage Works, in the modernization of which the IST Group invested more than 1 billion USD in 2008-2011, in its scale and applied technologies, is unique to Russian machine-building industry and is now the leader in carriage building in Russia. High-tech machine-building production is very sensitive to power supply disruptions, therefore, to ensure the required level of reliability and quality of power supply, the IST Group decided to upgrade the existing boiler house at the production site with the construction of a 220 MW Thermal Power Plant based on several Gas Reciprocating Units (GRUs) of the 18V50SG brand (electric capacity is 18.32 MW and thermal capacity is 18 MW) produced by Wärtsila.
Construction of a Gas Reciprocating Power Plant of such capacity is a unique project for the Russian energy industry. The TPP has the most powerful gas reciprocating engines, Wärtsilä 50SG, which ensure electrical efficiency of the power units by 48% (and taking into account the operation of the waste-heat recovery system of power units with a total capacity of 90 MW, the power plant efficiency reaches 90%), as part of its main generating equipment. Such facilities are highly maneuverable and provide quick start (for 5-10 minutes at a full capacity) fast reset, work at partial load, and are well adapted for systems with variable loads. High environmental performance in terms of emissions and noise allow you to install the GRUs in close proximity to the consumer. It is also important that when fuel efficiency is comparable with combined-cycle plants, Wärtsilä modular power units provide shorter construction and commissioning periods at lower capital costs.
The project is being implemented by ISM Engineering Company, a joint venture of the IST Group and Baran Group Ltd. (Israel). The project operator is Transmashenergo LLC. Trest Sevzapenergomontazh CJSC, in accordance with the obligations under two contracts concluded with Transmashenergo LLC in 2013-2014, fulfilled:
As part of the contract dated 23.12.2013 for the first step of construction, the following types of works were rendered:
As part of the contract dated 19.06.2014, a set of construction and installation works on construction and equipment of the main building with all engineering systems was performed:
Radiator cooling systems
Gas flues. Process trestles (arrangement of piled foundation, reinforced concrete foundation frames, installation of metal supports)
Oil control operating room and oil storage tanks (installation of reinforced concrete and metal structures, architectural and construction work, installation of oil systems and engineering systems of the oil control operating room)
Gas conditioning station (zero-cycle work, installation of a block-box of process equipment and a condensate tank of unit gas conditioning station)
Diesel generator set (arrangement of the base plate for the block container of a diesel generator)
The new gas reciprocating cogeneration plant has fully met the needs of Tikhvin Carriage Works and industrial enterprises of the Tikhvin site, taking into account the fact that no one has ever built a gas reciprocating power plant of such wattage in Russia.
