City gas distribution is a natural monopoly business: once a pipeline network is laid in a geographical area (GA), no second distributor can economically justify building a parallel network. Gujarat Gas holds exclusive PNGRB-authorised pipeline distribution rights in 35+ GAs across Gujarat and Rajasthan — primarily dense industrial and semi-urban areas where natural gas demand is high. The business model is similar to a toll road: the infrastructure investment (laying pipelines) is front-loaded, and then the business generates recurring margin on every cubic meter of gas passing through the pipes for the next 25+ years.
The Business: Volumes, Customer Mix, and Why Industrial Dominates
Gujarat Gas distributes approximately 12+ million standard cubic meters per day (MMSCMD) of natural gas — the largest volume of any CGD company in India. The customer mix is what distinguishes Gujarat Gas from peers like Indraprastha Gas (IGL, Delhi-NCR) or Mahanagar Gas (MGL, Mumbai): approximately 50–55% of Gujarat Gas volumes are industrial piped natural gas (PNG), versus 25% CNG for vehicles and 15% domestic household PNG. The industrial heavy-lifting comes from Gujarat's extraordinary manufacturing density — ceramics in Morbi, glass in Bharuch, chemicals in Dahej-Ankleshwar belt, textiles in Surat, and pharmaceuticals in Ahmedabad — all of which use natural gas as a process fuel. This industrial concentration creates three advantages: (1) Large offtake per connection — one ceramic kiln consuming 5,000 cubic meters per day is equivalent to serving 500 domestic households in margin economics; (2) Pricing power — industrial customers have no credible alternative fuel in the short term (diesel gensets for grid backup, coal kilns for some ceramics), giving Gujarat Gas some pricing latitude when input costs rise; (3) Long-term contracts — major industrial customers sign multi-year offtake agreements, providing volume visibility unavailable in the retail CNG business. Revenue FY25: approximately ₹16,000–17,000 crore (high because gas is a price-through commodity — the revenue is gas selling price × volume, not the margin); EBITDA margin: 13–15%; net profit: ~₹1,600–1,800 crore; ROCE: ~25–28%. Use our BBS Stock Scorecard to compare Gujarat Gas against IGL, MGL, and Indraprastha Gas — the contrast between Gujarat Gas's industrial-heavy, high-volume/lower-margin model and IGL's retail-heavy, lower-volume/higher-margin model reveals how two city gas distribution businesses can have very different earnings quality despite both being natural monopolies.

Gas Sourcing: The APM/LNG Mix Is the Margin Equation
Gujarat Gas's EBITDA margin is determined almost entirely by the difference between its gas selling price to customers and its gas buying cost — what the industry calls the "gas spread" or "gas margin." There are three sources of gas with very different costs: (1) Domestic APM gas (administered price mechanism, regulated by MoPNG) — the cheapest available, priced at ~$6–8/MMBTU; allocated by government to priority customers including CGDs for household and CNG use; (2) Domestic non-APM gas — market-linked but typically cheaper than LNG; (3) Imported LNG — most expensive, spot prices ranged from $5 to $60+/MMBTU during the FY22–23 global energy crisis post Russia-Ukraine war. When spot LNG prices spiked to $30–60/MMBTU in FY23, Gujarat Gas was forced to pass through higher costs to industrial customers — but the passthrough was partial and delayed, compressing margins significantly. EBITDA margins fell from 18–20% pre-FY22 to 11–13% at the trough in FY23. As LNG prices normalised to $10–13/MMBTU by FY25, margins recovered to 13–15%. The full recovery to 18–20% historical levels requires: (a) continued LNG price normalisation, and (b) increased APM gas allocation from the government (more cheap domestic gas reduces LNG dependency). Each additional MMSCMD of APM gas allocated to Gujarat Gas adds approximately ₹150–200 crore to annual EBITDA at current price spreads.

Morbi: The Industrial Moat and Concentration Risk in One City
Morbi, Gujarat is the world's largest ceramic tile manufacturing cluster — approximately 10,000 tile manufacturing units generating 80%+ of India's tile production for both domestic consumption and export to Africa, Middle East, and US. Every ceramic kiln runs on natural gas for the firing process — and Gujarat Gas has the exclusive pipeline infrastructure serving Morbi's industrial zone. Morbi consumes approximately 3 MMSCMD of Gujarat Gas's total 12 MMSCMD volume — roughly 25% of total volume from a single industrial cluster. This creates a powerful moat: Morbi tile manufacturers cannot switch to another gas supplier without constructing their own pipeline infrastructure (impractical), and cannot switch to an alternative fuel for kiln firing without major capital expenditure on kiln conversion (2–3 years and ₹10+ lakh per kiln). However, the same concentration creates risk: if Morbi tile exports face anti-dumping duties in key markets (the US has previously investigated Indian ceramic tiles), or if domestic demand for tiles softens in a real estate downturn, Gujarat Gas's volumes can drop significantly. Morbi has been resilient — exports grew despite global headwinds — but the concentration requires monitoring. Read our real estate analysis for the end-market context: the construction cycle that drives tile demand in India is directly linked to residential and commercial real estate completions — understanding when real estate activity peaks and troughs gives 12–18 month visibility into Morbi's tile demand.
🔍 BBS Insight
Gujarat Gas is a margin recovery and volume growth story — not a capital appreciation story from current business quality, but from the distance between current margins (13–15%) and normalised margins (18–20%) as gas sourcing economics improve. The investment thesis has two legs: (1) LNG price normalisation and APM gas allocation increase → margin recovery to 18%+ → earnings CAGR of 20%+ for 2–3 years; (2) New GA additions in Rajasthan and underpenetrated Gujarat GAs → volume growth of 8–10% annually on a large existing base. Key metrics each quarter: (1) EBITDA margin vs prior quarters — the single most watched number; recovery from 13% toward 18% is the bull case unfolding; (2) APM gas as % of total volumes — not always explicitly disclosed, but can be inferred from gas cost per unit versus LNG market prices; if company-reported gas cost is falling while market LNG prices are stable, it signals increasing APM allocation; (3) Volume growth in industrial segment — Morbi tile production and export data (published by CGCRI and industry associations) is a leading indicator for Gujarat Gas industrial volumes 1–2 months ahead; (4) New connection additions — particularly in Rajasthan GAs; the growth in new GAs is where the 10-year volume optionality resides, as Gujarat's core GAs are approaching maturity; (5) CNG realisation per kg — CNG pricing is market-linked (Gujarat Gas sets the price); any increase in CNG retail price above inflation signals pricing power is intact despite competition from EVs in the CNG vehicle segment.
