GIS for city gas distribution means using Geographic Information System (GIS) technology to plan, build, operate, and maintain the underground pipeline networks, CNG stations, and customer connections that deliver natural gas across a Geographical Area. In India’s rapidly expanding CGD sector, GIS serves as the platform that brings together pipes, pressure zones, isolation valves, and consumer endpoints into a single spatially organized system.
For CGD operators, regulators, and city planners, this provides a location-aware view of the entire gas distribution network. It enables them to visualize assets, analyze network performance, and make informed decisions from a centralized platform.
Why India’s Gas Story Needs a Map
India is in the middle of one of the most ambitious energy infrastructure build-outs in its history. The Petroleum and Natural Gas Regulatory Board (PNGRB) has now authorized 307 Geographical Areas (GAs) for CGD network development, covering close to 100% of India’s mainland, spanning 784 districts across 34 states and Union Territories. As of 2024, India had surpassed 13.6 million domestic PNG connections and established over 7,259 CNG stations. By 2034, the government targets 126 million PNG connections and 18,336 CNG stations.
That scale of expansion cannot be managed with spreadsheets and engineering drawings alone. Every pipe segment, every service line, every pressure regulator, every CNG station nozzle has a location. Managing that network safely and efficiently requires a system that understands not just what the assets are, but exactly where they are, how they connect, and what their current operational state is. That system is GIS.
What Is City Gas Distribution (CGD)?
City Gas Distribution (CGD) is the infrastructure and regulatory framework for delivering natural gas to residential, commercial, industrial, and transport consumers within a defined Geographical Area (GA). Each GA is awarded to an authorized entity through competitive bidding rounds conducted by PNGRB under the Petroleum and Natural Gas Regulatory Board Act, 2006.
CGD networks deliver gas in two forms. Piped Natural Gas (PNG) reaches homes, apartments, and commercial establishments through a network of steel and medium-density polyethylene (MDPE) distribution pipelines at low pressure. Compressed Natural Gas (CNG) is dispensed through filling stations for vehicles, offering a cleaner alternative to petrol and diesel. Both systems originate from city gate stations that receive gas from the national transmission grid, reduce pressure, and feed it into the local distribution network.
The Scale of India’s CGD Expansion: GAs, Bidding Rounds, and Targets
India had only 57 authorized GAs before 2014. Through 12 successive PNGRB bidding rounds, that number has grown to 307 GAs today. The 12th round specifically targeted the most difficult terrain, covering the six Northeastern states of Arunachal Pradesh, Meghalaya, Manipur, Nagaland, Sikkim, and Mizoram, along with J&K and Ladakh, completing the authorization of CGD networks across the entire Indian mainland.
The sector’s growth trajectory is steep. The CGD market is projected to grow at a CAGR of over 12% through 2031, with natural gas expected to account for 29% of India’s total gas consumption by 2030. CGD is forecast to be the largest single driver of India’s incremental natural gas demand over the next decade.
Despite this scale, 91 authorized GAs remained unconnected to the national gas grid as of mid-2025, and the pipeline of committed connections to be built across newly awarded territories is enormous. Turning this regulatory and market ambition into physical, operational infrastructure, city by city and street by street, is where GIS becomes indispensable.
Why GIS Is the Backbone of CGD Network Planning
A CGD network is a geographically distributed system. Unlike a power plant or a refinery, it exists entirely in the ground beneath city roads, colonies, industrial estates, and commercial corridors. No engineer or operator can see the full network without a map.
ArcGIS Utility Network is Esri’s purpose-built data model for gas distribution infrastructure. It represents every pipe segment, valve, regulator station, meter, and consumer endpoint as a connected network, not just a collection of mapped features. This connectivity model enables operations that are impossible with conventional GIS or CAD systems:
- Isolation valve analysis: When a leak is reported, operators can identify the minimum set of valves to close to isolate the affected segment while keeping as much of the network in service as possible
- Connectivity tracing: Trace gas flow upstream to identify the source of supply for any given customer, or downstream to map all consumers that a particular feeder main supplies
- Pressure zone management: Define and visualize pressure zones across the distribution network, ensuring that regulators and governors are correctly configured for each zone’s operating parameters
- Network integrity verification: Automatically validate that new connections and extensions comply with the network’s connectivity rules before any field crew begins work
This is the operational foundation that distinguishes a modern, GIS-powered CGD entity from one managing its network on disconnected drawings and registers.
How GIS Powers Each Stage of the CGD Lifecycle
New GA planning and CNG station siting
Before a single pipe is laid in a newly awarded GA, ArcGIS Pro enables spatial analysis of road networks, population density, traffic flow data, land use maps, and utility conflict zones to identify optimal CNG station locations and optimal trunk main routes. MoHUA’s advisory to state governments mandates earmarking land for CNG stations at the master plan stage. GIS bridges the gap between the CGD operator’s infrastructure plan and the ULB’s urban master plan, ensuring that proposed station plots align with zoned land use designations before any site is committed.
Construction and field surveys
ArcGIS Survey123 enables field teams to capture house-level PNG enrolment data, road and corridor surveyobservations, and as-laid pipe coordinates directly from tablets and smartphones, complete with GPS location and photographic documentation. ArcGIS Field Maps gives the same field crews offline access to the network map, so they can record new pipe installations and update asset attributes in the field even in areas without reliable connectivity. ArcGIS Workforce assigns and tracks field crew deployment for PNG connection campaigns, enabling supervisors to monitor door-to-door enrolment progress geographically in real time.
Operations and real-time monitoring
ArcGIS Velocity ingests live feeds from SCADA systems, IoT pressure and flow sensors, and remote monitoring units across the CGD network. Anomalous pressure drops, flow deviations, and suspected leak events are flagged spatially as soon as they develop, giving operations control rooms a georeferenced situational picture of network status rather than a list of raw sensor alerts.
BIM integration for station and infrastructure design
ArcGIS GeoBIM links BIM engineering models for new city gate stations, CNG compressor facilities, and district regulating stations directly to the GIS environment. Design engineers can verify that proposed infrastructure is correctly positioned in its real-world spatial context, checking for conflicts with roads, drainage lines, and other utility corridors before construction begins.
How Indian CGD Operators Are Using GIS Today
Gujarat Gas Limited (GGL), India’s largest city gas distribution company, has implemented a comprehensive GIS system on the Esri platform using ArcGIS and ArcFM. The platform covers commercial operations, engineering and design, construction and project management, maintenance, and emergency response within a single enterprise GIS environment. GGL subsequently migrated from an on-premises GIS to a cloud-based ArcGIS system, improving collaboration and connectivity across its geographically distributed operations. Real-time benefits include mobile emergency response, rapid identification of incident locations and affected consumers, pipeline maintenance tracking, effective site surveys, and streamlined field reporting.
Mahangar Gas Limited (MGL), which serves Mumbai and surrounding areas, has implemented both GIS mapping and SCADA integration for monitoring and controlling its entire CGD network. MGL’s SCADA coverage spans city gate stations, CNG stations, and critical sectionalising valve stations, with the GIS layer providing the spatial context for every network monitoring alert.
Indraprastha Gas Limited (IGL), operating one of India’s largest urban CGD networks in Delhi NCR, uses GIS combined with SCADA as a core tool for controlling and maintaining its extensive CNG and PNG infrastructure. IGL has identified third-party damage prevention and excavation conflict management as key GIS use cases, using network maps to alert contractors and other utilities to the presence of gas pipelines before any digging begins in the network area.

For consumers
Faster PNG connections because field teams using ArcGIS Field Maps and Survey123 complete enrolment and survey tasks more efficiently. Faster leak response because GIS-enabled operations centers can identify affected zones and dispatch repair crews to precise locations within minutes.
The CBG-CGD Synchronisation Opportunity
India’s Compressed Biogas (CBG) programme, which aims to produce biogas from agricultural waste, municipal solid waste, and industrial effluents, is converging with the CGD expansion. As CBG plants are commissioned across rural and semi-urban areas, they become potential supply nodes for the natural gas distribution network, feeding locally produced biomethane into the city gas grid at pressure regulation points.
GIS is essential for this integration. Indo ArcGIS Living Atlas provides the spatial data layers required to identify CBG plant sites relative to existing pipeline infrastructure, assess the pipeline distance and connection cost for each potential injection point, and model the incremental supply volumes that each CBG source would contribute to a GA’s gas balance. This spatial planning capability allows CGD operators and regulators to identify which biogas plants are economically viable to connect and which GAs would benefit most from decentralised CBG supply.
Challenges and the Road Ahead
Legacy network data
Many of the GAs awarded in earlier bidding rounds have partial or inconsistent GIS data. Pipe materials, installation dates, joint types, and depths were not recorded systematically in the early years of CGD development. Retrospective field surveys using ArcGIS Field Maps to capture as-installed asset attributes are a prerequisite for full ArcGIS Utility Network deployment in these areas.
Grid connectivity gaps
As of mid-2025, 91 authorized GAs remained unconnected to the national gas transmission grid. Until trunk pipeline connectivity is established, these GAs operate with CNG cascades or gas tankers, making full network GIS management less immediately relevant. PNGRB’s plans to connect 44 of these GAs through new pipeline extensions will trigger the next wave of CGD network build-out and the associated GIS foundation work.
Interoperability with SCADA and ERP systems
CGD operators typically run separate SCADA, billing, and enterprise resource planning systems. Integrating these with ArcGIS Enterprise so that network events, maintenance records, and consumer data are spatially queryable from a single platform is a significant IT integration investment, but one that unlocks the full operational value of the GIS foundation. India’s natural gas transition is fundamentally a geographic challenge. Every new PNG connection, every CNG station, every pipeline kilometer has a precise location that must be planned, recorded, monitored, and maintained. GIS, built on ArcGIS Utility Network and the broader ArcGIS Enterprise platform, is the system that makes the scale of India’s CGD ambition manageable, safe, and operationally sustainable across the decade of expansion ahead.
