In Ukraine, our largest facility built and commissioned is 750 kV Kakhovska substation, the construction of which was financed by the European Bank for Reconstruction and Development. In addition, in cooperation with German partners Decon international and Consulectra, with financing provided by the German bank KfW, a feasibility study was developed for SE NEC Ukrenergo for the modernization of 750 kV Zaporizka, 750 kV Dniprovska, 330 kV Kharkivska, 330 kV Zalyutine, 330 kV Krivorizka ,  330 kV Dnipro-Donbas substations. Also, tender requirements have been prepared. 

Substations Zelenogorsk 330 kV, Ruchey 330 kV, Zapadnaya 500/220 kV, Mzymta 110 kV were designed and built in Russian Federation.

A unique project is 220 kV Smirnovo underground substation on the site of Skolkovo innovation center in Moscow. The underground building is made in the form of an octahedron, with an outer diameter of 60 meters, the lower elevation of the building (the cable floor room) is located at elevation minus 18.950, the main power equipment of GIS 220 kV and gas-insulated transformers 63 MVA are installed at elevation minus 15.450. The project was developed taking into account the possibility of erecting an office building above the substation. TEP-SOYUZ has also developed detailed design for the overall renovation of 220 kV Mezhdurechenskaya substation, 220 kV Dagomys substation, 110 kV substation No. 127 in St. Petersburg, reconstruction of the Itatskaya substation 1150 kV, Abakanskaya substation 500 kV.
