The Turkish and Azeri presidents on Saturday inaugurated the Europe link of the strategic Trans-Anatolian Natural Gas Pipeline (TANAP).
The ceremony was held in the northwestern Turkish province of Edirne, near the border with Greece.
Turkish President Recep Tayyip Erdoğan stressed that the project dubbed as the project as the Silk Road of energy is a symbol of deep-rooted friendship between Turkey and Azerbaijan.
A dream of supplying 16 billion cubic meters of Azeri natural gas to Turkey and Europe has come true," Erdoğan added.
Erdoğan added that TANAP is the most important part of the 3,500-kilometer (2,174-miles) energy corridor which extends from Azerbaijan to Europe.
Erdoğan stressed that Turkey sought to contribute to the regional prosperity with the conclusion of the project, and added: "While guaranteeing our country's energy needs with TANAP, we also aimed at contributing to the safety of Europe's energy supply."
Bulgaria, Greece, North Macedonia, Albania, Serbia and Bosnia Herzegovina would also benefit from the mega project, said the Turkish leader adding that the TANAP was a project of "regional peace."
"This project has made it this far thanks to Turkey and Azerbaijan's relations based on mutual trust," Erdoğan said.
A total of 16 billion cubic meters of gas would be delivered through the project and the delivering capacity of the TANAP is projected to climb to 24-31 billion cubic meters over time, Erdoğan added.
The pipeline will begin carrying gas to the European section of the Southern Gas Corridor, an ambitious initiative of the European Commission for a natural gas supply route from the Caspian and Middle Eastern regions to Europe. It will pass through the Trans Adriatic Pipeline -- the European leg of the corridor.
Azerbaijani President Ilham Aliyev said the TANAP project will pave the way for boosting ties between the two nations.
"Today is a historic one. I hope the TANAP is going to last long, and Turkey, Azerbaijan and other neighboring countries will benefit from [TANAP]," he said.
"TANAP is an international cooperation project that essentially unites seven countries on the Southern Gas Corridor," Aliyev added.
"This project brings cooperation, stability, and long-term agreement," he said, adding the TANAP was more than just an energy project.
Notably, Aliyev hailed the strong bond Turkey and Azerbaijan shared, and said: "The strength of Turkey is the strength of ours."
Emphasizing that both countries shared a trade volume of $3.4 billion in the first nine months of this year, he said the mega projects achieved by both countries would boost ties and added: "After all, economic power transforms into political power."
Also speaking at the event, Turkey's Energy and Natural Resources Minister Fatih Donmez said TANAP's 1,850-kilometer (1,150-mile) journey in Anatolia ended, and now the gas journey to Europe started.
"TANAP is an energy project that reaches beyond the mountains, seas and straits with records to the inner parts of Europe," Donmez said.
In the first stage, 16 billion cubic meters and later 31 billion cubic meters of natural gas will be transported through the pipeline. The wealth coming from the depths of the Caspian will touch the lives of millions in all corners of Anatolia and Europe," he said.
"We always put forward the unifying mediator role of energy for the benefit of the region and all parties. Our energy diplomacy focuses on promoting regional stability and prosperity," said Donmez.
The TANAP project was officially launched in June 2018. It stretches from the Turkish-Georgian border to the Turkish-Greek border.
With an investment of around $7 billion, TANAP will deliver 6 billion cubic meters of Azeri gas to Turkey and 10 billion to Europe per year.
The pipeline passes through 20 provinces and 67 districts of Turkey.
