India’s Natural Gas Infrastructure: Building a More Connected National Gas Network

The objective is straightforward: make natural gas available to more regions, industries and consumers while improving the flexibility and resilience of the overall supply system.

India’s natural gas infrastructure now includes an extensive pipeline network, LNG import terminals, gas processing facilities, city gas distribution networks and storage infrastructure. According to the Petroleum and Natural Gas Regulatory Board (PNGRB), India had more than 25,000 km of operational natural gas pipelines as of 2025, with additional networks under development.

As this infrastructure expands, connectivity will become increasingly important to India's downstream oil & gas landscape.

India's gas infrastructure has historically developed around major producing regions, LNG terminals and large industrial demand centres. The expansion of the national gas grid is gradually connecting these individual networks into a broader system.

Pipeline connectivity allows imported LNG and domestic gas to move beyond coastal terminals toward inland markets.

This is particularly important for regions that previously had limited access to natural gas infrastructure.

A stronger national grid can support:

The result is a gas market that is increasingly interconnected rather than dependent on isolated regional networks.

India's growing dependence on imported LNG makes regasification infrastructure a critical component of the national gas network.

LNG terminals provide access to global gas markets and allow imported LNG to enter India's domestic pipeline system.

The development of additional regasification capacity, alongside expansion at existing terminals, can help India respond to rising gas demand. However, terminal capacity only creates value when it is effectively connected to pipelines and demand centres.

This makes terminal-to-pipeline connectivity increasingly important.

A well-connected LNG terminal can serve multiple markets rather than remaining dependent on demand within its immediate geographic area.

Industrial consumers remain an important driver of India's natural gas infrastructure development.

Fertilizer plants, refineries, petrochemical facilities, ceramics, glass, steel and other industries can use natural gas as a fuel or feedstock.

Expanding pipeline connectivity allows more industrial clusters to access gas without relying exclusively on localized supply arrangements.

For industrial users, stronger infrastructure can improve supply reliability while providing greater flexibility in sourcing.

For gas suppliers and infrastructure operators, connecting more demand centres can improve network utilization and create opportunities for long-term market growth.

The development of city gas distribution (CGD) networks is another major component of India's gas infrastructure strategy.

CGD networks deliver natural gas to:

The expansion of CGD infrastructure is helping bring natural gas into more cities and towns while creating new demand for pipeline capacity.

India's CGD network has expanded significantly over the past decade, with geographical areas covering the majority of the country's population and districts. (pngrb.gov.in)

This expansion creates a reinforcing cycle: greater pipeline connectivity enables more consumers to access gas, while growing demand supports further infrastructure investment.

A connected national gas network can also improve resilience.

India's gas market is exposed to changes in global LNG prices, international supply disruptions, domestic production levels and changing seasonal demand.

A diversified infrastructure network provides greater flexibility to redirect gas when individual supply routes or facilities experience constraints.

However, resilience also requires investment in asset reliability, pipeline integrity, cybersecurity, operational monitoring and emergency response capabilities.

As more critical infrastructure becomes digitally connected, protecting both physical and digital systems will become increasingly important.

India's natural gas infrastructure is evolving from a collection of regional systems into a more integrated national network.

The continued expansion of gas pipelines, LNG terminals, CGD networks and industrial connections can help create a broader and more flexible gas market.

But the next stage of development will depend on more than infrastructure capacity.

India will need to focus on how effectively these systems operate together.

Greater connectivity, digital monitoring, intelligent asset management and flexible supply planning can help transform the national gas grid into a more responsive infrastructure platform capable of supporting India's industrial and commercial growth.

India's natural gas opportunity is increasingly an infrastructure story.

The expansion of pipelines and LNG terminals is creating the physical foundation for a larger gas market, while CGD networks are extending that infrastructure to businesses, industries and consumers.

The strategic opportunity now is to connect these systems more effectively.

A well-integrated, digitally enabled and resilient national gas network can improve supply flexibility, expand access to natural gas and strengthen India's downstream infrastructure for the years ahead.
