Mumbai CNG Price Climbs to ₹86 as Cheap Gas Vanishes

Mahanagar Gas Limited pushed the price of compressed natural gas (CNG, the cleaner road fuel that powers most of Mumbai’s autos and taxis) to ₹86 per kilogram on Saturday, a ₹2 increase that lands just sixteen days after the last one. It is the second CNG price hike in Mumbai this month, and it leaves the city’s drivers paying ₹4 per kilogram more than they did on May 13.

The company blamed costlier gas and a weaker rupee. The pressure behind that line has been building for more than a year, as the government steadily pulled cheap domestic gas away from city distributors and left them buying expensive imports to fill the gap.

Two Hikes, Sixteen Days, and a ₹4 Jump

Mahanagar Gas Limited (MGL), the dominant city-gas distributor across Mumbai, Thane and Navi Mumbai, has moved twice in quick succession. The first revision on May 14 took CNG from ₹82 to ₹84 a kilogram. Saturday’s revision added another ₹2 on top, and it arrived alongside a 50-paise increase in domestic piped natural gas (PNG), the cooking-gas supply households get through pipes, now priced at ₹52 per standard cubic metre (SCM).

Between those two pump increases came a quieter move that hit businesses first. On May 25, MGL told customers it was withdrawing support schemes and subsidies for commercial users, citing the same cost pressure. The sequence, laid out in the company’s official Mumbai gas price revision notices, reads as a steady ratchet rather than a one-off shock:

1. May 14: CNG raised ₹2 to ₹84 a kilogram, MGL’s first revision of the month.
2. May 25: MGL withdraws support schemes and subsidies for commercial customers.
3. May 30: CNG raised another ₹2 to ₹86 a kilogram; domestic PNG lifted 50 paise to ₹52 per SCM.

The Cheap-Gas Cushion That Slipped Away

For two decades, India kept CNG affordable by feeding city distributors a large slice of cheap domestic gas sold under the Administered Price Mechanism (APM, the government-set rate for legacy gas from old ONGC and Oil India fields). That cushion is now far thinner than it was, and the May increases are the price tag.

From Half the Pipeline to a Third

Starting in April 2025, the government cut the APM allocation to city-gas firms such as MGL by up to a fifth, then trimmed it again across the following quarters. The result is that cheap domestic gas now covers about a third of city-gas demand, down from roughly half a year earlier, according to industry allocation data tracked alongside the government’s natural gas consumption figures.

What slipped away was not the gas itself but its price. Every kilogram of allocation lost has to be replaced, and the replacement does not come at the administered rate.

Why the Replacement Gas Costs More

The shortfall gets filled with imported liquefied natural gas (LNG) and gas from high-pressure, high-temperature fields, both priced off global benchmarks and paid for in dollars. So a falling rupee makes the same molecule dearer in rupee terms even before global prices move. Stack a weaker currency on top of a smaller cheap-gas pool, and the cost floor under CNG simply rises.

• About one-third of city-gas demand now met by cheap APM gas, down from roughly half a year earlier.
• Up to 20% the size of the APM allocation cut first imposed on distributors from April 2025.
• ₹52 per SCM the new domestic PNG rate after Saturday’s 50-paise increase.

How the West Asia Conflict Tightened the Tap

The structural squeeze met a sudden supply scare this spring. Conflict across the Middle East disrupted LNG shipments, hit traffic through the Strait of Hormuz, and pushed some suppliers to invoke force majeure clauses on cargoes bound for India.

On March 9, the Ministry of Petroleum and Natural Gas (MoPNG) invoked the Essential Commodities Act, 1955 and notified a fresh rationing rule. The text of the Natural Gas Supply Regulation Order, 2026 set a four-tier priority that protects household and transport fuel before anything else:

• Priority I: domestic PNG, CNG for transport and LPG production, supplied at up to 100% of recent average consumption.
• Priority II: the fertiliser sector, at 70% of recent average consumption.
• Priority III: industrial and grid-connected consumers, at 80%.
• Priority IV: city-gas industrial and commercial buyers, at 80%, subject to availability.

Here is the catch for commuters. CNG sits at the top of that list on volume, so the pumps keep flowing. But the protected volume is being filled with costlier pooled gas, redirected by Gas Authority of India Limited (GAIL) and re-priced by the Petroleum Planning and Analysis Cell. Volume is safe; the bill is not.

Who Absorbs the Hike in Mumbai

The weight lands on the people least able to pass it on. Mumbai’s CNG fleet has grown past 12 lakh vehicles, including roughly 4.7 lakh auto-rickshaws, more than 1.6 lakh taxis and over five lakh private cars. For a driver who fills 8 to 10 kilograms a day, a ₹4 jump in a fortnight quietly eats into daily takings before a single fare changes.

Households feel the second pinch through cooking gas. The domestic PNG rate climbing to ₹52 per SCM adds to monthly bills for the piped-gas homes MGL serves, a cost that arrives without the option of switching fuels mid-month.

MGL set out its reasoning plainly in the statement that accompanied the increase.

Due to a significant increase in gas procurement costs caused by reduced allocation of domestic gas, increased dependence on higher-cost gas sources and depreciation of the Indian Rupee, the overall cost has risen considerably.

That was MGL’s official note issued in Mumbai after Saturday’s revision, the same statement in which the company said it would keep looking for ways to optimise costs and pass on benefits to consumers.

Delhi, Noida and the Nationwide Climb

Mumbai is not moving alone. In North India, Indraprastha Gas Limited (IGL), the leading distributor for the capital region, lifted CNG by ₹6 a kilogram across four tranches between May 15 and May 26, taking the Delhi rate to ₹83.09. Other city-gas firms have followed in their own piecemeal way, citing the same input-cost and currency pressure flagged in the petroleum ministry’s recent gas supply notifications.

The spread across the metros shows how uneven the pass-through has been, with satellite towns around Delhi already well above the Mumbai and central-Delhi rates.

CNG’s Shrinking Lead Over Petrol

The selling point for CNG was always the savings. A switch from petrol historically cut running costs by around 40%, and a switch from diesel by roughly 25%, which is what convinced lakhs of cab and auto owners to convert.

That gap is narrowing with every revision. In Delhi, CNG still runs about ₹18 a kilogram below petrol and more than ₹11 under diesel on a straight pump-price basis, and on cost-per-kilometre it remains the cheaper way to drive. But the cushion that made conversion an easy decision is thinner than it has been in years.

The math is no longer obvious at the margin. For a fleet owner weighing a new vehicle, a smaller price gap against a higher upfront cost and patchy refuelling queues changes the sum.

If the West Asia disruption eases and the rupee steadies, the pooled price could soften and some of May’s increases may unwind. If the conflict drags on and domestic allocation keeps shrinking, the next revision will not be the last, and the gap that made CNG worth the switch will keep closing.

Frequently Asked Questions

Why has the CNG price increased in Mumbai?

MGL raised CNG because its gas procurement cost has jumped. The government has cut the cheaper domestic gas allocated to city distributors, forcing MGL to buy more costly imported gas, and a weaker rupee has made those dollar-priced imports dearer. The West Asia conflict added a fresh supply scare on top.

What is the new CNG price in Mumbai?

CNG in Mumbai, Thane and Navi Mumbai now costs ₹86 per kilogram after the ₹2 hike on May 30, 2026. That is ₹4 higher than on May 13, following two increases in sixteen days.

Is CNG still cheaper than petrol in 2026?

Yes, but by less. In Delhi, CNG still sits roughly ₹18 a kilogram below petrol and over ₹11 under diesel, and on a cost-per-kilometre basis it remains the cheaper option. The savings gap has narrowed sharply from the 40% advantage CNG once held over petrol.

What is APM gas and why does it affect CNG prices?

APM gas is domestically produced natural gas sold at a government-set rate from older ONGC and Oil India fields. It is much cheaper than imported gas. When the government reduces the APM volume given to city distributors, they must replace it with pricier imports, which pushes CNG prices up. APM now covers about a third of city-gas demand, down from roughly half a year ago.

How much did piped cooking gas rise in Mumbai?

MGL raised domestic piped natural gas by 50 paise per standard cubic metre on May 30, taking the rate to ₹52 per SCM. The increase applies to households using MGL’s piped cooking-gas connections.

Will CNG prices rise further in India?

It depends on two things: how long the West Asia supply disruption lasts and whether the government restores domestic gas allocation to distributors. If both ease, prices could stabilise or dip. If they persist, further small hikes of ₹1 to ₹2 a kilogram remain likely as distributors protect their margins.
