Gazprom has started construction of the Kazachya compressor station in Krasnodar Territory, part of its Southern Corridor natural gas transmission system feeding the South Stream export pipeline to Europe (OGJ Online, Apr. 4, 2013).
The 220-Mw station will be able to handle the transmission system’s full capacity of 63 billion cu m/year of gas. It will have eight compressor units. From the Kazachya station, gas under pressure of 11.8 MPa will flow to the Russkaya compressor station. There it will enter the South Stream line, which will cross the Black Sea to southern and central Europe. South Stream construction began late last year.
The Southern Corridor system will have two legs, to be built in phases with the western leg first, joining at Russkaya. In addition to feeding the South Stream export line, it will supply markets in central and southern Russia.
The system, due for completion in 2017, will have total length of 2,506 km. Its 10 compressor stations with total capacity of 1,516 Mw.
The Kazachya station is on the western leg of the Southern Corridor system. The northernmost of the western leg’s compressor stations will be at Pisarevka in Voronezh Oblast.
The northernmost of the longer eastern leg’s compressor stations will be at Pochinki in Nizhny Novgorod Oblast.
