Indradhanush Gas Grid

What Indradhanush Gas Grid does

Indradhanush Gas Grid Limited (IGGL) is a Joint Venture of five Indian public-sector undertakings — Indian Oil Corporation (IOCL), Oil and Natural Gas Corporation (ONGC), GAIL (India), Oil India Limited (OIL), and Numaligarh Refinery Limited (NRL) — incorporated on August 10, 2018 in Guwahati, Assam to implement the Hydrocarbon Vision 2030 for Northeast India. The company is building and operating the North East Gas Grid (NEGG), a planned 1,670 km high-pressure natural gas transmission pipeline connecting the capital and major cities of all eight Northeastern states (Assam, Arunachal Pradesh, Meghalaya, Manipur, Mizoram, Nagaland, Tripura, Sikkim) to India's National Gas Grid via the Barauni-Guwahati pipeline under the Urja-Ganga scheme. The total project cost is Rs 9,265 crore, funded through promoter equity and government Viability Gap Funding; physical progress reached 87.42% as of March 2026, with Phase I (553 km across Assam, Arunachal Pradesh, and Nagaland) inaugurated by the Prime Minister on March 14, 2026. Core infrastructure includes SCADA and Automatic Pipeline Protection Systems, the Baihata compressor station with bi-directional flow capability, 35 permanent stations along GNPL/GIPL/DDPL, metering skids, pigging facilities, cathodic protection, and telecom/optical fiber systems.

IGGL generates revenue through PNGRB-regulated natural gas transmission tariffs (usage-based, distance/throughput based) on volumes moved from upstream sources (ONGC's Silchar/Jorhat/Tripura Agartala fields, Oil India's Duliajan fields, HOEC's Dirok field) to demand centers (Numaligarh Refinery, NEGDCL city gas distribution network, BCPL petrochemicals, industrial and tea garden consumers, future residential PNG customers in Mizoram and other states). Commercial operations commenced in November 2025 with supply to NRL through the Guwahati-Numaligarh Pipeline; supplementary revenue comes from Right of Use sharing arrangements with BCPL and DNPL. The company sells exclusively on a B2B basis via bilateral Gas Transmission Agreements, Hook-Up Agreements, and RoU-sharing MoUs — there is no direct consumer-facing channel. The customer base is concentrated on state-owned energy and refining entities, with regulatory and strategic alignment to the five promoter PSUs.

Revenue model

1. Natural Gas Transmission / Transportation Tariffs: IGGL generates revenue through regulated natural gas transmission tariffs approved by the Petroleum and Natural Gas Regulatory Board (PNGRB). The company transmits natural gas from source points (ONGC fields, Dirok gas fields, upstream producers) to demand centers (refineries like NRL, CGD networks, industrial consumers) through its pipeline network. Revenue is based on throughput volumes and PNGRB-determined tariffs. The company has been included in Additional Unified Tariff Paths by PNGRB.
2. Right of Use (RoU) Sharing Revenue: IGGL earns revenue from sharing Right of Use of pipeline infrastructure with other entities such as BCPL (for Duliajan Feeder Pipeline) and Duliajan Numaligarh Pipeline Limited (DNPL). This involves contractual arrangements for third parties to utilize IGGL's pipeline capacity.

Broad incumbents

• Mahanagar Gas Limited (MGL): MGL operates CGD networks in Mumbai and adjacent areas and is a joint venture of GAIL and BG (Shell). It is comparable to IGGL's downstream CGD counterparties (NEGDCL, TNGCL) and offers a benchmark for gas distribution unit economics in Indian metros.
• Hindustan Petroleum Corporation Limited (HPCL): HPCL is a major Indian PSU oil & gas company with CGD operations (HPOIL Gas) and is structurally comparable to IGGL's PSU parent set (IOCL, ONGC, GAIL, OIL, NRL). Relevant for benchmarking PSU-led gas infrastructure investments.
• Indraprastha Gas Limited (IGL): IGL is the largest listed city gas distribution (CGD) company in India (Delhi NCR). It is a key downstream counterparty type for IGGL, as CGD entities like NEGDCL represent IGGL's volume ramp path. IGL provides a benchmark for gas-distribution economics and PNGRB-regulated tariff structures.
• Gujarat Gas Limited: Gujarat Gas is one of India's largest CGD players, serving industrial and domestic customers across Gujarat. It is comparable to IGGL's downstream CGD counterparties and provides an India CGD demand-supply benchmark.
• Adani Total Gas Limited: Adani Total Gas operates CGD networks across multiple Indian states and represents a broader-incumbent in the gas distribution ecosystem that IGGL's CGD counterparties (NEGDCL, TNGCL) compete with or operate alongside for downstream PNG and CNG sales.
• Indian Oil Corporation Limited (IOCL): IOCL is IGGL's largest promoter and one of India's largest downstream and CGD operators. While IOCL is the sponsor rather than competitor, its CGD arm represents the corporate parent reference for how integrated PSU gas distribution is structured.

Direct peers

• GAIL (India) Limited: GAIL is India's largest natural gas transmission operator (≈15,000 km of pipelines) and is both a promoter of IGGL and the operator of the connecting Barauni-Guwahati pipeline under the Urja-Ganga scheme. GAIL's gas transmission business is the most direct comparable for IGGL's regulated midstream model.

Regional players

• Sabarmati Gas Limited: Sabarmati Gas is a CGD operator in Gujarat (a joint venture of BPCL and GSPC). It is comparable to IGGL's downstream CGD counterparties in scale and structure, providing a benchmark for emerging-state CGD unit economics in India.

Others

• Petronet LNG Limited: Petronet LNG operates India's primary LNG import terminals. It is comparable as part of the same regulated gas value chain — IGGL's grid explicitly targets reducing dependence on LNG imports (~$500M annually) that Petronet would otherwise handle, making it a strategic counter-party in the broader ecosystem.

Emerging players

• Green Gas Limited: Green Gas is a mid-sized CGD operator focused on Uttar Pradesh cities. Comparable as a regional CGD peer whose PNG/CNG distribution model IGGL's downstream customers (NEGDCL, TNGCL) mirror at smaller scale.
