6.2.2 Planned network
Given the inadequacy of the current pipeline network, pipeline operators are making plans to connect
major demand centres in the region. The planned route of the gas grid in the northeast is shown
below.
a) National gas grid (Barauni- Siliguri-Bongaigon-Guwahati pipeline network)
The network is proposed to span 800-900 km and is expected to cost Rs 3,600-4,050 crore. Once
completed, all key gas demand-supply centres in the region will be connected. However, the project is
economically non-viable and still to take off.
Besides connecting the Northeast to the national gas grid, the gas-producing station needs to be
connected to other demand centres. As Mizoram and Tripura will account for bulk of gas production, it
is imperative to connect these two states on a priority basis. Further, as Barauni is already being
connected to the national gas grid through Jagdishpur-Barauni pipeline, it makes sense to propose
pipeline from Barauni to the rest of the Northeast. The figure below is the geographical map of the
pipelines considered for feasibility network.

b) Proposed gas pipeline - Duliajan-Guwahati (by OIL)
The 1 MMSCMD Duliajan-Numaligarh gas pipelines, with utilisation rate of 75-80% is proposed to be
extended to Guwahati and subsequently to Bongaigaon for catering refineries. AGCL has carried out
pre-feasibility survey on this route. However, the project has not progressed further.
6.3 Product pipelines in northeast India
6.3.1 Existing pipelines
Currently, the region has a product pipeline network of over 1,126 km that transports petroleum
products such as diesel, petrol, etc, from refineries to different locations. OIL is the largest player with
a network over 654 km; followed by IOCL.
