Ukraine's natural gas transmission system is the second largest in Europe, with a pipeline infrastructure that is 35,000 kilometers in length and contains 171 compressor stations. In recent years, Ukraine has transported 70 to 76 billion cubic meters of natural gas to Ukrainian consumers and transited more then 120 billion cubic meters of natural gas to European countries and Turkey.
Outdated leak detection technologies and insufficient measurement practices lead to significant gas leakages in the gas distribution pipelines of the former Soviet Union. It is estimated that leaks account for up to 5% of transmitted gas volume.
The cost of gas leakage is passed on to the consumer. Gas distribution companies are paid for the volumes of gas that they transit, on the basis of the volumes that enter their system. Leaks are typically repaired only to the extent that they represent safety risks, and the technology employed is typically suboptimal.
Projects to reduce gas leakage in distribution pipelines consist of three stages: (i) identification and measurement of leaks; (ii) repair of detected leaks; and (iii) design and implementation of a maintenance and monitoring program.
Gas distribution pipelines present attractive JI projects: emissions from gas leakage have a high impact on global warming, as natural gas is essentially methane; and emission reductions can be achieved cost-effectively, mostly through the repair of leakage points at pipeline stations, rather than costly investments in reconstruction of pipeline systems.
