Measurement of volumes of gas and its qualitative indicators at the entrance to the GTS of Ukraine is carried out by 12 GMS, and at the output – 11. The last ones make the accounting of gas transported to European countries, including the countries of the Balkan region.
GTS
gas transmission system. It performs two main functions: providing domestic consumers with natural gas, as well as transit of natural gas through the territory of Ukraine to the countries of Western and Central Europe.
Gas refinery plant
is an industrial enterprise, which produces individual hydrocarbons, their mixes, helium, liquefied gases, hydrocarbon black and scrape from associated and natural gases. Oil and gas refineries in Ukraine produce liquefied gas andare subjected to JSC Ukrgazvydobuvannya and PJSC Ukrnafta, which are subdivisions of NJSC Naftogaz of Ukraine.
H

SPP
solar power plant. Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), indirectly using concentrated solar power, or a combination.
Small hydro
is the development of hydroelectric power on a scale corresponding to river flow capacity and suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid.
