Trans-Anatolian Natural Gas Pipeline (TANAP)

Energy, as one of the most critical factors in international relations, shapes countries’ economic and strategic positions. In particular, natural gas serves as a strategic important in global energy markets, while energy place security, diversification, and control over transit routes hold the potential to create strong economic and political ties between nations. In this context, the Trans Anatolian Natural Gas Pipeline Project (TANAP) has emerged as a major initiative strengthening energy cooperation between Türkiye and Azerbaijan, while simultaneously enhancing Europe’s energy supply security. TANAP aims to establish a pipeline transporting natural gas from the Caspian region to Europe and is generating profound impacts on global energy geopolitics.

The Global Importance of Natural Gas and Its Role in Türkiye

Natural gas is an important energy source in the world energy market, distinguished by its environmentally friendly characteristics. It is preferred both in industry and domestic use as a common fuel. Natural gas reserves are concentrated especially in Russia, Iran, Qatar and some Middle East countries. As of 2009, a large portion of the world’s natural gas reserves were located in the Middle East and Europe-Eurasia regions, with Russia holding 24 percent of global reserves.

Natural gas emits less carbon dioxide than coal and oil, making it a more environmentally friendly fossil fuel. Additionally, due to its efficient combustion properties, natural gas generates energy with high efficiency and produces less harm pollution. However, its storage and transportation are more costly and complex compared to other fuels. Nevertheless, its ease of transport via pipelines has increased its significance in global energy trade.

Türkiye has shown significant growth in natural gas consumption and has become an energy corridor for transporting natural gas from Central East and the Caspian region to Europe. The TANAP and Turkish Stream such as projects have strengthened Türkiye’s energy strategy and solidified its role in the global energy market.

The History and Development of TANAP

The TANAP project aims to build infrastructure to transport natural gas produced from Azerbaijan’s Shah Deniz-2 field to Türkiye and Europe. This project reflects the deepening energy cooperation between Azerbaijan and Türkiye and seeks to diversify and secure Europe’s energy supply. The foundations of TANAP were laid with an Intergovernmental Agreement (IGA) signed between Azerbaijan and Türkiye on 25 October 2011. Supported by the Turkish State Planning Organization and special agreements, the project began construction on 17 March 2015 and achieved its first natural gas flow in 2018.

The project’s cost is estimated at approximately seven billion dollars, with an annual capacity projected to reach up to 31 billion cubic meters. While TANAP extends from Türkiye’s eastern border to its western regions, it will also deliver gas to Europe through the borders of Greece and Bulgaria.

Technical Specifications and Capacity

The TANAP pipeline has a diameter of 56 inches and a total length of 1,850 kilometers. This pipeline enhances Türkiye’s energy transit capacity and plays a vital role in meeting Europe’s natural gas demand. TANAP’s capacity is planned to increase from six billion cubic meters to 31 billion cubic meters by 2026. This capacity expansion may grow further depending on Azerbaijan’s production production levels. Through this project, Türkiye will supply gas for domestic consumption while also delivering reliable natural gas exports to Europe.

Economic Outcomes and Collaborations

The economic impacts of TANAP extend beyond the energy sector, generating significant results in construction, engineering, technology and employment. The project has provided Azerbaijan and Türkiye with long-term economic gains while increasing regional employment and contributing to economic growth. Through TANAP, Azerbaijan has not only gained access to export its natural gas to European markets but has also solidified its position as a strategic player in the energy sector. Türkiye has established itself as an energy transit hub and made substantial contributions to its energy supply security. Furthermore, the participation of major energy companies such as SOCAR (Azerbaijan State Petroleum Corporation) and BOTAŞ has strengthened the economic dimension of Turkish-Azerbaijani cooperation.

Thirty percent of the natural gas transported through TANAP to Europe will be absorbed by Türkiye, with the remainder exported to European markets. This situation enhances Türkiye’s energy supply security while offering Europe a vital alternative energy source. Additionally, through TANAP, Türkiye aims to gain greater control over energy transit flows.

Geopolitical and Strategic Impacts

TANAP is not merely an economic project; it holds major geopolitical and strategic significance. While transporting Azerbaijan’s energy resources to European markets, the project seeks to reduce dependence on traditional energy suppliers such as Russia and Iran. For the European Union, TANAP is a critical step for energy security and diversification. In this context, TANAP aims to reduce Europe’s reliance on Russian energy and diversify its supply sources.

For Azerbaijan, TANAP will increase natural gas exports and establish it as a strategic player in the European market. The project strengthens Azerbaijan’s energy strategy and expands SOCAR’s economic and strategic reach. This enables Azerbaijan to become not only an energy producer but also a key player in energy infrastructure development.

Türkiye’s role has been strengthened both as a transit country and as a country supplying energy to Europe. Through TANAP, Türkiye has transformed into a center that both produces and transports energy. This development has enhanced Türkiye’s strategic importance in global energy markets and deepened its relations with Europe.

The Relationship Between TANAP and TAP

Another major project implemented alongside TANAP is the Trans Adriatic Pipeline (TAP). TAP completes the European extension of TANAP by transporting natural gas from Greece through Albania and across the Adriatic Sea to Italy. TANAP and TAP are considered complementary hat. Together, these two projects, supported by the EU to enhance energy supply security, hold great importance in diversifying natural gas supplies to Europe and reducing dependence on Russia.

TANAP’s Contributions to Türkiye’s Energy Strategy

TANAP is a vital component of Türkiye’s energy strategy. Türkiye has signed various projects to ensure energy supply security, control energy prices, and reduce external energy dependency. TANAP represents a strategic step toward achieving these goals and reinforces Türkiye’s role as an energy corridor. Moreover, TANAP deepens Türkiye’s energy cooperation with the EU and supports the enhancement of Türkiye’s technological capacity in the energy sector.
