Rustavi-Poti Gas Pipeline is a proposed gas pipeline in Georgia.

Location

The pipeline is proposed to run from the Azerbaijan-Georgian border to the Black Sea Coast, passing along the parallel East-West gas pipeline system route.

Background

The length of the pipeline on the territory of Georgia is about 370 km, the diameter - 36” (the internal diameter - 888.8 mm, the wall thickness - 12.7 mm) or 42” (the internal diameter - 1034.2 mm, the wall thickness -15.88 mm), to be precisely defined in the detail design process. The design pressure of the pipeline is 95 bars and the operating pressure – 90 bars. The maximum height from the sea level - 1120 m. As the results of hydraulic modelling show, for D=36’’ pipeline, with 2 interim compressors of about 23 MW in combined capacity, the system can supply at least 8.5-10 bcm. The transmission capacity of D=42’’ pipeline of the same configuration would reach about 14.5-15 bcm (combined capacity of compressor stations to be about 33-35 MW). The investment cost for Rustavi-Poti D=36’’ pipeline is estimated at about 570 M€ (≈630 M$) and for D=42’’ pipeline - at about 63546 M€ (≈700 M$). With 15% incidental costs, the investment costs would increase to 635 and 700M€, respectively.

As of August 2023, there have not been updates about the project since publication of the "Ten-Year Development Plan for Georgian Gas Transmission Network 2019-2028" in 2018. The project is not listed on the website of Georgian Oil & Gas Corporation. However, since construction of the pipeline was planned to begin after 2023, the project is not considered shelved or cancelled yet.
