Indraprastha Gas Ltd is fundamentally a utility that replaces dirty, trucked-in fuels with cleaner, piped natural gas for millions of homes, vehicles, and factories in and around Delhi. It was created in 1998 by two state-owned energy giants, GAIL and BPCL, specifically to build Delhi’s first city-wide gas grid, and it later cemented its position by becoming the sole distributor of CNG and piped gas in the capital, converting all public buses and over 1,600 polluting factories. The recurring approach that explains everything else is a regulated infrastructure moat: IGL lays a vast, exclusive pipeline network in a dense, mandate-driven market, and then uses the cash flows from that core to seed the same model in new districts and to build adjacent clean-energy businesses. # Business segments A single integrated utility engine with two customer-facing fuel streams - CNG for vehicles and PNG for homes and businesses - both flowing through the same pipeline network, plus a set of early-stage green-energy bets under construction. ## 1. CNG for vehicles: the dominant cash engine **Compressed natural gas sold as a cheaper, cleaner transport fuel to roughly 2.1 million vehicles through a network of 955 stations, with pricing protected by a government allocation of low-cost domestic gas.** - **The fuel that runs the capital’s buses** - IGL has a long-term supply agreement with the Delhi Transport Corporation, and built dedicated filling facilities at 44 bus depots with a combined compression capacity of 10 lakh kgs per day. - **A station network that is hard to copy** - the company runs 955 CNG stations, about 13% of all such stations in India, and is steadily converting older “daughter booster” stations to more efficient “online” configurations that connect directly to the steel pipeline grid. - **Cheaper fuel by regulatory design** - the government reserves a firm allocation of domestic gas for the entire CNG segment, which keeps the pump price competitive against petrol and diesel and makes vehicle conversion economically attractive for owners. - **The electric bus headwind is real but narrow** - institutional CNG offtake from DTC and DIMTS bus fleets is migrating to electric and is expected to reach zero by March 2026, yet underlying demand is strong: monthly vehicle conversions rose from an average of 21,000 to 26,000 after a GST cut on CNG vehicles, and 31,000 new CNG vehicles were added in October 2025 alone. - **OEM partnerships lock in demand** - IGL runs joint promotions with Maruti Suzuki, Tata Motors, Bajaj, Mahindra, and Hyundai, all of which now sell factory-fitted CNG variants, so new-car buyers enter the ecosystem directly. ## 2. Piped natural gas: the mandate-driven household and industrial franchise **Natural gas piped directly into more than 32 lakh homes and 12,800 commercial and industrial premises, where regulatory bans on dirtier fuels compel switching.** - **The law is the strongest salesperson** - the Delhi Pollution Control Committee has banned all other industrial fuels where PNG is available, and the Commission for Air Quality Management has directed diesel generator sets across Delhi and the NCR to switch to PNG or dual-fuel mode. - **Domestic gas priced against subsidised LPG** - households use PNG for cooking, and the price is kept competitive because the domestic PNG segment, like CNG, receives a government allocation of cheaper domestic gas. - **Industrial pricing follows a formula** - for factories and commercial kitchens, IGL uses a formula-based price linked to its own sourcing cost so it can stay competitive with alternate fuels, and it has identified high-potential industrial pockets in Gurugram, Greater Noida, and Ghaziabad to target volumes. - **Customer acquisition is low-cost and digital** - the company uses e-rickshaw promotions, women’s community meets, QR codes, and bulk messaging to sign up households, and it has achieved a 97% adoption rate for online bill payments while delivering electronic bills to over 1.35 million subscribers. ## 3. The pipeline grid: the shared infrastructure backbone **A network of over 2,500 km of steel pipeline and 29,200 km of MDPE pipe across 12 geographical areas in four states, built under a 300-month exclusivity period that makes duplication nearly impossible.** - **Exclusivity is written into the licence** - under PNGRB regulations, IGL has a 300-month exclusivity period from the date of issue of this communication to lay, build, and expand its city gas network, and a 60-month exemption from opening its pipelines to third-party carriers. - **The grid is the moat** - management cites the sheer scale of 955 stations and thousands of kilometres of pipeline as a major deterrent for new entrants, especially in the NCT of Delhi where IGL has already built infrastructure across every part of the territory. - **New areas are seeded with mobile kit** - in newly awarded districts, IGL starts by deploying cascade (daughter booster) systems at an additional cost of about ₹10-12 crores while it lays steel pipeline in parallel, so it can begin selling gas before the permanent network is complete. - **Safety is operationalised, not just stated** - the company runs a dedicated Safety Day on the 11th of every month, conducted over 400 safety camps and 433 mock drills in FY25, and operates 24/7 Emergency Control Centres across Delhi and the NCR to respond to gas leaks. ## 4. Cleaner-energy bets: the future-fuel portfolio under construction **A collection of early-stage ventures in compressed biogas, LNG for long-haul trucks, EV charging, green hydrogen, and solar power, each built on the cash flows and customer relationships of the core gas distribution business.** - **Biogas from waste, piped into the same grid** - IGL is off-taking compressed biogas from six plants and has signed MoUs with technology partners to build 19 more plants across four states, targeting a capacity of 0.45 MMSCMD, roughly 5% of its daily gas requirement; a 100-tonnes-per-day municipal solid waste plant is under construction at Narela in Delhi. - **LNG for trucks where pipelines don’t reach** - one LNG/LCNG station is already operational in Ajmer, two more are being built in Rewari and Greater Noida, and an MoU with CONCOR explores putting LNG infrastructure inside container terminals and even moving LNG by rail from Gujarat seaports. - **EV charging** - 33 chargers have been commissioned in Delhi, with a target of at least 50 fixed chargers, and 8 standalone EV charging stations are already set up, positioning IGL at the same forecourts where CNG is sold. - **Green hydrogen and solar at pilot-to-project scale** - IGL has signed MoUs with ACME Cleantech for blending green hydrogen into its existing pipeline network and with BHEL for hydrogen-compatible cylinders, while a solar plant in Rajasthan is being set up through a joint venture with the state’s power generation company. # Group structure and partners **IGL is a joint venture between two Maharatna state enterprises, with a subsidiary making smart gas meters and two associate companies replicating the city-gas model in other Indian cities.** - GAIL (India) Limited and Bharat Petroleum Corporation Limited (BPCL) are the promoters, with the Government of NCT of Delhi holding a 5% equity stake; the Managing Director is nominated by GAIL and the Chairman by BPCL. - IGL Genesis Technologies Limited (IGTL), a 51:49 joint venture with Genesis Gas Solutions, was set up to manufacture India’s first integrated smart gas meters at a plant in Noida with an initial capacity of 1 million meters per year. - Central U.P. Gas Limited (CUGL) and Maharashtra Natural Gas Limited (MNGL) are 50%-owned associate companies that operate city gas distribution networks in cities including Kanpur, Bareilly, Pune, and Nasik. - New joint ventures have been formed with Rajasthan Rajya Vidyut Utpadan Nigam Limited for a 500 MWp solar project (74:26 equity), and with CEID Consultants and Hindustan Waste Treatment (both 50:50) for compressed biogas plants.
