North Caucasus Transcaucasia Pipeline, also called the Mozdok - Tbilisi - Yerevan Pipeline (Russian: Газопровод Моздок-Тбилиси; Владикавказ (Моздок)-Тбилиси-Ереван) is an operating gas pipeline in Russia, Georgia and Armenia. The portion of the pipeline that falls within the territory of Georgia is also called the North-South Gas Pipeline (Russian: Север-Юг).

Location

The pipeline runs from Mozdok, Russia, to Tbilisi, Georgia, and to Yerevan, Armenia.

Background

The North Caucasus-Transcaucasia Gas Pipeline runs through the territory of Russia (137 km), Georgia (263 km) and Armenia (212.5 km). The Mozdok-Tbilisi segment of the pipeline is a backup pipeline. Based on research, it appears the it runs parallel to the main pipeline.

The pipeline frequently suffers from accidents due to landslides and rockfalls. In 2010, a large reconstruction/rehabilitation project of the North-South gas pipeline was completed. Another reconstruction project was completed in 2016, partially financed by USAID.

Attacks on pipeline in North Ossetia

Two bombings of a section of the pipeline in North Ossetia, Georgia in 2006 led Georgia to reduce its imports of natural gas from Russia and instead import gas from Azerbaijan.
