Energy Corridors and Pipelines

India’s energy pipeline network forms the circulatory system of its industrial geography, bridging the spatial divide between resource-rich extraction zones, coastal import terminals, and landlocked consumption hubs. The development of this infrastructure is governed by the Petroleum and Natural Gas Regulatory Board (PNGRB) under the Ministry of Petroleum and Natural Gas. As the world’s third-largest energy consumer, India uses pipelines as the most energy-efficient, cost-effective, and safe mode for moving bulk hydrocarbons over long distances, minimizing railway and highway freight congestion.

Crude Oil Pipelines: Sourcing and Refinery Connectivity

Crude oil pipelines connect domestic offshore/onshore oilfields and maritime import ports with inland public sector refineries. They ensure a continuous supply of feedstock to regions lacking natural fossil fuel reserves.

Cross-Country Crude Oil Arteries

Dedicated LPG Pipelines

• Jamnagar-Loni LPG Pipeline: Operated by GAIL (India) Limited, this is one of the world’s longest cross-country LPG pipelines. It moves LPG from the Jamnagar refining complex in Gujarat across Madhya Pradesh and Rajasthan to Loni in Uttar Pradesh, feeding bottling plants across the National Capital Region (NCR).
• Kandla-Gorakhpur LPG Pipeline: A massive pipeline under execution designed to transport LPG from Kandla port in Gujarat directly to Gorakhpur in eastern Uttar Pradesh. It addresses the rising domestic fuel demand generated under the PM Ujjwala Yojana across Madhya Pradesh and Uttar Pradesh.

Natural Gas Pipelines and the National Gas Grid

The National Gas Grid is a priority infrastructure project aiming to build a synchronous nationwide gas network, increasing the share of natural gas in India’s primary energy mix from approximately 6.7% to 15%. This grid connects domestic gas fields (such as Krishna-Godavari basin and Assam fields) and Liquefied Natural Gas (LNG) regasification terminals to fertilizer plants, power stations, and City Gas Distribution (CGD) networks.

The Structural Core of the Gas Grid

• Hazira-Vijaipur-Jagdishpur (HVJ) Pipeline: This is the foundational backbone of India’s natural gas distribution geography. Operated by GAIL, it originates at Hazira in Gujarat, passes through Vijaipur in Madhya Pradesh, and terminates at Jagdishpur in Uttar Pradesh, with branches extending to Delhi, Haryana, and Rajasthan. It serves as the primary feedstock supplier to major fertilizer plants and thermal power units across North India.
• Jagdishpur-Haldia & Bokaro-Dhamra Pipeline (JHBDPL) – Pradhan Mantri Urja Ganga: This project connects eastern India to the national gas grid. It runs through Uttar Pradesh, Bihar, Jharkhand, West Bengal, and Odisha, supplying gas to revived fertilizer units at Gorakhpur, Barauni, and Sindri, while feeding CGD networks in major eastern cities.
• Barauni-Guwahati Pipeline: Developed as an extension of the Urja Ganga project, it crosses the chicken’s neck corridor to link the North-Eastern region with the National Gas Grid.
• North-East Gas Grid (Indradhanush Gas Grid): Developed by a joint venture of public sector units, this grid connects all eight northeastern states in a synchronous loop. It links local gas fields in Assam and Tripura with the main trunk line from Barauni, boosting industrialization in the region.
• Kochi-Koottanad-Bangalore-Mangalore Pipeline: Connects the LNG regasification terminal at Kochi to industrial consumers in interior Kerala, coastal Karnataka (Mangaluru), and the tech-industrial hubs of Bengaluru.
• Dabhol-Bengaluru Pipeline: Integrates the LNG terminal at Dabhol in Maharashtra with the industrial corridors of northern and central Karnataka.

Infrastructure Mapping and Operational Pipeline Framework

Technical, Spatial, and Geopolitical Challenges

Right of Use (RoU) and Land Acquisition

Pipelines require a continuous, linear stretch of land under Right of Use (RoU) provisions. Acquiring this easement across fertile agricultural zones, densely populated semi-urban settlements, and ecologically sensitive forest tracts often leads to prolonged legal disputes and local community resistance.

Geomorphic and Tectonic Vulnerabilities

The North-East Gas Grid and the Barauni-Guwahati extensions traverse complex geomorphic terrains, including the floodplains of the Brahmaputra river and seismically active zones (Zone V) of the eastern Himalayas. Ensuring the structural integrity of pipelines against severe riverbed scouring, seasonal landslides, and soil liquefaction requires advanced engineering and continuous automated monitoring.

Safety, Pilferage, and Third-Party Encroachment

Inland product lines face threats from illegal hot-tapping and fuel pilferage, which can cause severe ecological damage through soil and groundwater contamination. Pipelines also require continuous protection against accidental third-party excavation impacts near urban industrial corridors.
