On August 29, 2026, Indraprastha Gas Limited implemented a calibrated price revision of Rs 3.89 per kg, taking CNG prices in Delhi to Rs 86.98. This marks the fifth increase this year and the first since May, when IGL raised prices by Rs 6 per kg across four phases over ten days. The immediate trigger: elevated international LNG prices driven by the ongoing West Asia conflict, with spot LNG prices surging since the conflict began.
IGL's cost structure is significantly influenced by its gas procurement mix. Currently, 42% of procurement comes from imported RLNG, making input costs sensitive to international market movements. The company maintains 100% term contracts—60% Henry Hub-linked and 40% Brent-linked—eliminating spot procurement exposure but still subject to indexation volatility. Transcripts +1
The LNG component has increased from 25% to 37% of total procurement in Q2 FY26 due to reduced domestic allocations, directly increasing gas costs. Current LNG prices hover around $10-11 per mmBtu, creating substantial margin pressure. This cost inflation is visible in IGL's financials: FY27 Q1 expenses grew 14.73% year-over-year while revenue increased only 9.62%, with EBITDA margins contracting to 9.54% from 13.56% in the previous quarter .

IGL follows a deliberate pricing strategy focused on market stability rather than immediate cost recovery.
The latest Rs 3.89 per kg increase is described as a "partial offset" to input cost increases, not full pass-through. Transcripts
Historical patterns reveal flexible timing based on cost pressure intensity. In May 2026, IGL implemented Rs 6 per kg in increases over ten days—a rapid, staggered approach. The current Rs 3.89 per kg increase after a three-month gap suggests a more measured approach. This 8-10 month lag between LNG cost increases and price adjustments reflects strategic deferral pending regulatory changes and competitive positioning considerations. Transcripts
At the revised price, IGL faces significant margin challenges.
The partial nature of the current price hike suggests margins will remain under pressure in the near term. Transcripts +1
However, several factors support margin recovery. Regulatory benefits expected from PNGRB's unified tariff rationalization could deliver Rs 0.70-1.30 per SCM savings. VAT reduction on domestic gas from Gujarat from 15% to 2% provides approximately Re 1 per SCM benefit. Operational efficiency initiatives have already reduced power and fuel costs by Rs 0.05-0.06 per SCM. Combined, these benefits provide a pathway toward the Rs 7-8 margin target over the next 2-3 quarters. Transcripts +2
IGL employs a diversified procurement approach to manage cost risks. The current mix shows 43% domestic sources (including APM, NWG, HPHT), 42% RLNG, 7% New Well Gas, 6% HPHT, and 2% other. Management aims for a 50-50 split between domestic and RLNG sources for optimal risk management, though quarterly variations occur based on allocation availability. Transcripts +1
The company maintains more than 100% contract coverage with medium and long-term agreements, eliminating spot procurement needs. This structure provides visibility and reduces exposure to spot market volatility, though indexation to Henry Hub and Brent crude still creates exposure to global energy price movements. Transcripts
Despite the price increase, CNG demand in Delhi-NCR demonstrates relatively inelastic characteristics. Excluding the impact of DTC and DIMTS bus fleet transitions to electric mobility, underlying CNG volume growth remains robust at approximately 10% year-on-year. This resilience stems from mandatory CNG usage for commercial vehicles in Delhi-NCR, limited substitutes for commercial operators, and established infrastructure creating high switching costs.

Historical data suggests minimal volume disruption from price increases.
The current price increase to Rs 86.98 per kg is expected to result in volume decline of only 2-4%, with net revenue increase of 1-4%.
Despite the increase to Rs 86.98 per kg, CNG maintains a significant cost advantage over alternative fuels. Petrol currently costs Rs 102.12 per litre in Delhi, while diesel stands at Rs 95.20 per litre. CNG offers 35-40% lower running costs compared to petrol and 30-45% savings versus diesel. For taxi operators, this translates to monthly savings of Rs 4,500-7,500 at 100 km per day operations.
The regulatory environment further supports CNG's competitiveness. GST on CNG vehicles was reduced from 28% to 18%, significantly improving competitiveness versus EVs. Post-GST cut, monthly CNG vehicle additions increased from 21,000 to 26,000, with October alone witnessing 31,000 new additions. Transcripts +1
IGL operates under PNGRB's comprehensive regulatory framework, which provides both enabling mechanisms and constraints for pricing decisions. PNGRB has granted exclusive marketing rights to CGD players in designated geographical areas for set periods, while also mandating consumer protection measures. AnnualReports +1
Recent regulatory changes significantly benefit IGL. PNGRB's unified tariff rationalization effective January 1, 2026, reduced pipeline transmission tariff zones from three to two, with Zone 1 tariff of Rs 54 per mmBtu applicable nationwide for CNG and domestic PNG regardless of distance from gas source. IGL's geographical areas previously fell under Zone 2 and Zone 3, now classified under Zone 1, providing estimated cost savings of Rs 0.70-1.30 per SCM. Transcripts
Compared to other CGD entities, IGL's regulatory position has improved significantly. Mahanagar Gas Limited in Mumbai has demonstrated more aggressive price pass-through historically, with multiple hikes of Rs 2-7 per kg to offset input costs. Gujarat Gas Limited benefits from proximity to gas sources and already operates under favorable Zone 1 tariffs.
The unified tariff benefits IGL more substantially than peers given its previous distance disadvantage. While MGL and Gujarat Gas have limited incremental benefit from tariff rationalization, IGL gains significant cost advantages that support margin recovery and competitive positioning. Transcripts
The Rs 3.89 per kg price hike provides partial margin relief, but full recovery depends on multiple factors. Expected EBITDA margin improvement in FY27 Q2 ranges from 80-150 basis points, with continued recovery through FY27 Q4 as regulatory benefits fully materialize. Management maintains confidence in achieving Rs 7-8 per SCM EBITDA margins by FY28 Q1 . Transcripts
The recovery path combines pricing actions, regulatory benefits, and operational improvements. Volume growth of 10-11% annually supports economies of scale, while infrastructure efficiency—with 97.5% of sales through online stations—provides operational leverage. The company's balanced sourcing strategy and upcoming regulatory benefits position it well to navigate LNG price cycles while maintaining financial viability. Transcripts +1
IGL's current pricing dynamics reflect a balancing act between cost recovery imperatives and market stability objectives. The Rs 86.98 per kg price represents a calibrated response to elevated LNG costs while maintaining competitive positioning. With relatively inelastic demand, significant regulatory tailwinds, and a clear margin recovery roadmap, IGL appears well-positioned to navigate the current cost environment while sustaining its role as Delhi-NCR's primary clean energy provider.
