Some local transmission lines together with distribution sets are owned by regional gas companies.
[7] In addition, the system includes 72 compressor stations with 702 compressors, having a total capacity of 5,442.9 MW, and 13 underground gas storage facilities with an active storage capacity of 30.9 billion cubic metres (1.09 trillion cubic feet).
[8] Before 2012, gas entered to Ukraine only from entry points on borders with Russia and Belarus.
Most of the gas transit went to Slovakia and further to other countries in Central and Western Europe.
Smaller amount of natural gas was transported to Hungary, Poland, Romania, and Moldova.
[10] In 2012–2014, some entry/exit points with Poland, Hungary, and Slovakia were modified to also allow the gas flow to be reversed from these countries back into Ukraine.
In 2004, the Ukrainian Centre for Economic and Political Studies estimated its value at $12–13 billion.
The European Union financed the feasibility study which was conducted by Mott MacDonald.
[3] According to the master plan of Ukrtransgas, the priority objects are Soyuz, Progress, Urengoy–Pomary–Uzhhorod, Yelets–Kremenchuk–Kryvyi Rih and Ananyiv–Tiraspol–Izmail pipelines, Bilche–Volytsko–Ugerske and Bohorodchany underground gas storages, and Uzhhorod, Berehove, Drozdovychi, Tekove and Orlivka gas metering stations.
[3] The development of Ukrainian gas pipeline system started in Galicia, then part of Poland.
In the 1940–1960s, it was mainly built to use the Galician gas in other regions of the Soviet Union.
It leaves Ukraine through the Uzhhorod gas metering and pumping station.
[8] The Yelets–Kursk–Dykanka and the Kursk–Kyiv pipeline enters Ukraine through the Sudzha gas metering station.
[10] The Yelets–Kremenchuk–Kryvyi Rih pipeline enters into Ukraine through the Sudzha gas metering station.
[20] This corridor, crossing Luhansk Oblast in Eastern Ukraine, consists of the Southern Caucasus–Centre pipeline system.
[2][21] However, during the Russian invasion of Ukraine Russia used this corridor to supply Donbas regions not controlled by the Ukrainian Government through the Prokhorivka and Platovo gas metering stations.
