TAPI stands for the Turkmenistan-Afghanistan-Pakistan-India gas pipeline. The project is designed to carry natural gas from Turkmenistan through Afghanistan and Pakistan toward India, creating a long regional energy corridor.
Asian Development Bank project documents describe the pipeline as roughly 1,600 kilometres from the Turkmen-Afghan border to the Pakistan-India border, with a planned full capacity of 33 billion cubic metres of natural gas a year. Older project descriptions often refer to an overall route of about 1,800 kilometres when upstream and connecting sections are included.
Afghanistan matters in two ways. First, it sits in the middle of the physical route. Gas cannot move south from Turkmenistan through the planned corridor without crossing Afghan territory. Second, Afghanistan is itself intended to receive a share of the gas.
Supporters argue that the project could give Afghanistan access to additional energy, create transit revenue, generate jobs and strengthen economic links with neighbouring countries. It could also help Turkmenistan diversify its export markets and give Pakistan and India another source of gas.
But TAPI has faced delays for many years. A pipeline of this scale requires financing, security, land access, engineering work, compressor stations, cross-border agreements and long-term buyers. Political announcements therefore do not automatically mean gas is about to flow.
A useful way to read TAPI news is to separate four stages: diplomatic agreement, financing, physical construction, and commercial operation. Progress in one stage does not prove that the next stage has been completed.
For Afghanistan, the most important question is not only when a section is built, but when gas can actually be delivered safely and commercially through an operating system.
