Gujarat State Petronet Ltd is the energy backbone of India’s most gas-hungry state - it owns the high-pressure pipeline grid that connects every major import terminal and domestic gas field in Gujarat to the factories, power plants, and city gas networks that need the fuel. Incorporated in 1998 by the Gujarat government to build a state-wide gas grid on an open-access principle, the company was built on a philosophy of “creating demand rather than following demand,” laying pipes into new markets before customers were ready. That recurring approach - build the infrastructure first, then let the demand come - explains why GSPL today is a pure transmission toll-booth, moving over 15% of all the natural gas consumed in India without ever buying or selling a molecule of the gas itself. # Business segments Three engines at different stages - a regulated pipeline monopoly that is the company’s reason for being, a pair of interstate pipeline bets that extend its reach beyond Gujarat, and a small fleet of wind turbines selling electricity to the state grid - each built on the cash flows and connectivity of the core transmission grid. ## 1. Natural gas transmission: the toll bridge on Gujarat’s gas highway **GSPL owns the only statewide high-pressure gas grid in Gujarat, a 2,795-kilometre network that charges a regulated fee for every unit of gas moved - a natural monopoly with a captive customer base that includes its own subsidiaries.** - **Paid by volume, not by gas price** - the company earns transportation tariffs on a per-unit basis from customers who book capacity on its pipelines, so it makes money whether natural gas prices rise or fall; it never takes ownership of the gas itself. - **The tariff is set by the regulator** - the Petroleum and Natural Gas Regulatory Board (PNGRB) uses a cost-plus formula that allows a 12% post-tax return on capital employed, with tariffs reviewed every five years, giving revenue visibility even though the current tariff of ₹18.10 per MMBTU is under appeal after a sharp reduction from the earlier ₹34. - **Connected to every major supply source** - the grid links all four operational LNG import terminals in Gujarat (Mundra, Hazira, Dahej, and Vapi) plus domestic gas fields from Cairn Energy, GSPC, and the Panna-Mukta-Tapti fields, making GSPL the essential evacuation route for gas entering Western India. - **Its own affiliates are anchor customers** - subsidiary Gujarat Gas Ltd contributed roughly 33% of transmission revenues in FY25, and associate Sabarmati Gas Ltd added another 4%, creating a built-in demand base that no competitor can access. - **A licence that blocks duplication** - to lay a pipeline in its service area, any player must win exclusive authorisation from PNGRB through a bidding process, which means no rival can build a parallel grid and GSPL faces virtually no direct competition within Gujarat. ## 2. Interstate pipeline joint ventures: extending the grid beyond Gujarat **GSPL holds 52% stakes in two pipeline companies that carry gas from Gujarat’s LNG terminals to customers in Northern and Central India - bets that the same transmission-toll model can work at national scale.** - **One pipeline is already earning** - GSPL India Gasnet Ltd (GIGL) has built roughly 1,440 kilometres of the planned 1,560-kilometre Mehsana-Bhatinda-Gurdaspur pipeline through Gujarat, Rajasthan, Haryana, and Punjab, and achieved commercial operations in August 2024, generating turnover of nearly ₹240 crore in FY25. - **The other is a toehold in the East** - GSPL India Transco Ltd (GITL) has an initial 365-kilometre section operational in Andhra Pradesh and Telangana, connecting a gas dispatch terminal to a fertiliser plant, with volumes of 2.08 MMSCMD in FY25. - **Oil-marketing companies are the partners** - Indian Oil, Bharat Petroleum, and Hindustan Petroleum together hold the remaining 48% in GIGL, sharing the capital burden while GSPL retains control and consolidates the ventures. - **The logic is volume pull-through** - every new customer connected in Punjab or Rajasthan via GIGL’s pipeline ultimately draws gas that must first travel through GSPL’s Gujarat grid, so the interstate ventures feed volumes back into the core transmission business. ## 3. Wind power generation: a small, stable side bet **A 52.5 MW fleet of wind turbines sells electricity to the Gujarat state grid under a long-term purchase agreement - a non-core but predictable revenue stream that has nothing to do with gas.** - **Sold entirely to the state utility** - all power generated across five plants in Rajkot and Porbandar districts goes to Gujarat Urja Vikas Nigam Ltd under a Power Purchase Agreement, eliminating customer-acquisition risk. - **Small in the scheme of things** - the wind business sold about 86.5 million kilowatt-hours in FY25 and accounted for under 3% of total turnover, so it is a rounding item next to the transmission grid. # Group structure and partners **GSPL sits inside a state-owned group that spans the entire gas value chain - from exploration and trading through to the last-mile city gas connection - and is in the final stages of a merger that will fold the company into its own subsidiary while spinning the transmission assets into a new listed entity.** - **The promoter is the Gujarat government** - parent Gujarat State Petroleum Corporation Ltd (GSPC), a state undertaking, holds 37.63% of GSPL, and GSPC itself is India’s second-largest natural gas trader, moving roughly 15 MMSCMD of gas and having imported more than 400 LNG cargoes. - **The subsidiary is India’s largest city gas distributor** - GSPL owns 54.17% of Gujarat Gas Ltd, which operates 27 CGD licences across 44 districts in six states, serving over 22 lakh households with piped natural gas and running more than 810 CNG stations. - **An associate fills the North Gujarat gap** - GSPL’s 27.47% stake in Sabarmati Gas Ltd covers five districts with 161 CNG stations and nearly 3 lakh domestic connections. - **A stake in an LNG terminal completes the chain** - GSPL holds 26% of GSPC LNG Ltd, which owns a 5 MMTPA regasification terminal at Mundra, giving the group a position at the point where imported gas first enters the pipeline system. - **A merger is reshaping the structure** - under a Composite Scheme effective 1 May 2026, GSPL, GSPC, and GSPC Energy Ltd amalgamate into Gujarat Gas Ltd, and simultaneously the gas transmission business demerges into a new listed company, GSPL Transmission Ltd; post-merger, the Gujarat government will directly hold roughly 26% of both GGL and GTL, with total government entities holding about 55%.
