More than three decades have passed since the planning of the TAPI project, which is one of the important projects for Afghanistan and the regional countries. However, the work on the TAPI project has not yet been completed.

It is expected that with the implementation of the TAPI project, in addition to supplying Afghanistan's required gas, thousands of job opportunities in various sectors will be created in the country. With the completion of the TAPI project, other projects, including the 500 kV power transmission to Pakistan, fiber optics, and the establishment of railways, will also be implemented in Afghanistan.

After its separation from the former Soviet Union in December 1991, Turkmenistan began its efforts to transfer gas to South Asia. When the Islamic Emirate came to power in 1996, it initiated formal talks with Turkmenistan to implement the TAPI project. However, the practical work on this project did not begin at that time. 

The leaders of Turkmenistan, Afghanistan, Pakistan, and India held consultations about TAPI three times in 2015, 2010, and 2018.

Finally, a meeting was hosted in Herat in 2018. Alongside the commencement of the TAPI project, the work on the 500 kV power transmission, railway, and fiber optics projects also began.

Sayed Masoud, an economic analyst, said about the TAPI project: "TAPI is one of Afghanistan's major regional projects that is entangled in a deadly regional competition; a competition that exists between Pakistan and India, a competition between Turkmenistan and Iran, and a competition among Turkmen, the Emirates, and Qatar."

According to information from the Ministry of Foreign Affairs of the Islamic Emirate, the TAPI project will annually transfer 33 billion cubic meters of Turkmenistan's gas to Afghanistan, Pakistan, and India. 
In addition to meeting Afghanistan's gas needs, the implementation of the TAPI project will bring Afghanistan around $450 million dollars in transit fees annually and create job opportunities for thousands of people in the maintenance and security sectors.

Shirbaz Kaminzada, the head of Afghanistan's Chamber of Industries and Mines, said: "TAPI is a massive project, and our areas are agricultural; there are mines here, and we can use cheap energy and gas. One of the major problems in the lack of mining extraction and mechanization of our agriculture is the shortage of energy."

The TAPI project is not a single project; several other projects will also be implemented along with this gas pipeline. One of these projects is the 500 kV power transmission project between Turkmenistan, Afghanistan, and Pakistan, which transfers Turkmenistan's electricity to Pakistan through Afghanistan. Afghanistan is expected to earn up to $110 million annually in transit fees from this electricity transmission.

Additionally, fiber optic cables will be laid in the region, connecting neighboring countries. Another project that will be implemented along with the TAPI gas pipeline is the railway, which will connect Pakistan and Turkmenistan through Afghanistan.

Mohammad Karim Azimi, another economic analyst, said: "Along with the TAPI project, the TAP project and the construction of the railway, which are its supplementary projects, are very important."

The total length of the TAPI gas pipeline is 1,814 kilometers. This pipeline passes through the provinces of Herat, Farah, Nimroz, Helmand, and Kandahar, with 816 kilometers running through Afghanistan.

The TAPI project, estimated to cost $10 billion, passes through Afghanistan along the Herat-Kandahar highway and then through Quetta and Multan in Pakistan, reaching the city of Fazilka in India.
