The overall CBG blending ratio in compressed natural gas (CNG) and domestic piped natural gas (PNG) reached 0.92% in 2025-26, nearly meeting the government’s 1% mandate, according to data published by the Petroleum and Natural Gas Regulatory Board (PNGRB).
In 2025-26, total CNG and domestic PNG sales stood at 12,033 million metric standard cubic meters (MMSCM), of which CBG sales were 111.5 MMSCM.
The government mandate for CBG blending began last fiscal year and will rise to 3% in the current year, 4% in 2027-28 and 5% in 2028-29. The government introduced the CBG mandate for city gas distributors to make use of local energy resources and help cut dependence on imported liquefied natural gas, which accounts for around 50% of India’s needs.
Torrent Gas, Indraprastha Gas, BPCL, Gujarat Gas and Gail Gas were the top five sellers of CBG. Torrent alone sold 21.4% of the total CBG sold by city gas distributors.
BPCL clocked the highest CBG blending ratio, at 4.15%, in 2025-26 among 11 city gas distributors that sell more than 100 MMSCM of CNG and domestic PNG. AGP City Gas was second, with a blending ratio of 3.45%, and Torrent Gas was third, with 3.41% blending. HPCL, Avantika, Gujarat Gas, GAIL Gas, GAIL (India) and Vadodara Gas all had blending ratios above 1%.
Indraprastha Gas, Adani Total, MGL, MNGL, IRM Energy and Bhagyanagar Gas had blending ratios of less than 1%.
India currently has 207 functional CBG plants. The government has been encouraging the setting up of more such plants to boost output. The Cabinet last week approved GOBARdhan, the National Circular Bioenergy Scheme, with a total outlay of Rs 23,731 crore. The scheme aims to provide a strong framework to boost India’s CBG programme through assured demand, remunerative and stable pricing, capital assistance, pipeline infrastructure, credit support and technology development.
