1.1 The topic of the GRES diploma project is 880 MW, developed on the basis of PUE, R&D, PTB documents.

1.2 In accordance with the issued assignment, this 880 MW GRES is being built in the Western Siberia region.

1.3 Western Siberia is a part of Siberia located between the Ural Mountains in the west and the Yenisei River channel in the east. The area of ​ ​ the region is 2.6 million km (15% of the territory of Russia). The population is 15 million people (10% of the population of Russia). The population density is 5.77 people. by 1 km.

1.4 Western Siberia is a territory stretching 2500 km from the Arctic Ocean to the uplands of the Kazakh shallow sediment and 1900 km from the mountains of the Urals to the Yenisei. About 80% of the area of ​ ​ Western Siberia is located within the West Siberian Plain, which consists of two flat bowl-shaped very swampy depressions, separated by Siberian Uvals elevated to 175-200 m. In the southeast, the West Siberian Plain, gradually rising, is replaced by the foothills of Altai, Salair, Kuznetsk Alatau and Mountain Shoria.

1.5 The most developed fields of industry are oil, gas, coal and forestry. In Western Siberia, more than 70% of all-Russian oil and gas production, about 30% of coal and 20% of wood are mined. There is a powerful oil and gas production complex. The area of ​ ​ oil and gas-bearing lands is about 2 million km.

1.6 The largest cities - Novosibirsk, Omsk, Tyumen, Barnaul, Novokuznetsk, Tomsk, Kemerovo, Kurgan, Pavlodar, UstKamenogorsk, Surgut.
