Trans-Caspian Gas Pipeline Returns to Spotlight — But Political Obstacles Remain Deep
A long-delayed energy project caught between Russia, China and the West
The long-discussed Trans-Caspian Gas Pipeline (TCP) is once again being pushed into the international spotlight amid growing uncertainty over energy security and supply routes following tensions and conflict around Iran.
Presented for decades as a strategic route that could connect Central Asian gas reserves with European markets, the project has repeatedly stalled due to geopolitical pressure, competing interests and the cautious approach of Turkmenistan.
The pipeline would link Turkmenistan and Azerbaijan through the Caspian Sea, allowing Turkmen gas to enter the Southern Gas Corridor and eventually reach European Union markets via Türkiye, Greece and Italy.
However, despite years of political declarations, the project remains largely a promise rather than a reality.
A project trapped by geopolitical rivalry
First proposed in 1999 with US support, the original plan involved companies such as Bechtel and General Electric and envisioned transporting around 32 billion cubic meters of gas annually at a cost exceeding $5 billion.
Turkmenistan took steps to prepare for the project, including launching its East-West domestic gas pipeline in 2015, designed to bring up to 30 billion cubic meters of gas toward the Caspian coast.
But the offshore section — the most politically sensitive and technically challenging part — was never built.
The main reasons were clear: opposition from Russia and Iran, delays in securing Western financing, and Turkmenistan’s growing dependence on China as its main energy customer.
A smaller project raises bigger questions
A scaled-down version of the pipeline has since been discussed, with estimated costs of $500 million to $800 million and a planned capacity of only 10–12 billion cubic meters per year.
But analysts question whether such a limited project would justify the political risks for Ashgabat.
John Roberts of the Global Energy Center at the Atlantic Council argues that Turkmenistan faces a difficult calculation: risking relations with Russia for a relatively modest export route may not be attractive.
“If the project involved 30 billion cubic meters, the strategic argument would be much stronger. At 10 billion, the benefits are far less convincing,” experts argue.
Washington’s support, Ashgabat’s silence
The United States has recently renewed its support for exporting Turkmen gas through the Trans-Caspian route.
During meetings in Washington, US officials expressed support for developing Turkmenistan’s vast gas resources and expanding export opportunities.
However, the Turkmen government has avoided openly committing to the pipeline. Official statements have focused on broad issues such as energy security, transport connectivity and export diversification — without directly mentioning the Trans-Caspian Gas Pipeline.
Observers see this as a continuation of Turkmenistan’s long-standing policy of neutrality and caution in balancing relations with major powers.
China remains the dominant player
While Western countries have promoted alternative routes, China has become Turkmenistan’s most important energy partner.
In recent years, Ashgabat has expanded cooperation with the China National Petroleum Corporation, including projects linked to the development of the giant Galkynysh gas field and increased exports toward China.
Beijing currently remains the largest buyer of Turkmen gas, with annual export volumes estimated at around 30 billion cubic meters.
Analysts argue that China benefits from keeping Turkmenistan as an alternative supplier, using Central Asian gas as leverage in its own negotiations with Russia over energy prices and supply conditions.
A battlefield of competing interests
Former Uzbek energy official Anvar Khusainov describes the Trans-Caspian pipeline as a highly promising project, but one caught in a struggle between competing global powers.
Russia, China, the United States, the European Union, Türkiye and regional actors all have strategic interests connected to the project.
This geopolitical competition has become one of the biggest reasons why a pipeline that has been discussed for more than two decades still exists mainly on paper.
Türkiye pushes for a breakthrough
Türkiye remains one of the strongest supporters of the project.
President Recep Tayyip Erdoğan has argued that there are significant opportunities to expand cooperation on delivering Turkmen gas through Azerbaijan and Türkiye to European markets.
Türkiye’s Energy Minister Alparslan Bayraktar has suggested that political conditions may finally be moving closer to implementation.
Yet optimism from Ankara does not eliminate the central problem: the project still depends on whether Turkmenistan is willing to make a strategic choice and whether major powers will accept a new energy corridor bypassing their influence.
A strategic dream facing political reality
The Trans-Caspian Gas Pipeline remains one of Eurasia’s most discussed but least realized energy projects.
Its supporters see it as a way to diversify Europe’s gas supplies and reduce dependence on traditional routes. Critics point out that after more than 25 years of negotiations, political uncertainty continues to outweigh economic logic.
For the pipeline to become reality, Turkmenistan must receive convincing economic guarantees, security concerns must be addressed, and competing powers must accept a redistribution of influence in the region.
Until then, the Trans-Caspian project remains less a pipeline under construction and more a symbol of the geopolitical struggle over Central Asia’s energy future.
