India’s major oil marketing companies are encouraging commercial LPG users to switch from traditional gas-based cylinders to more efficient liquid off-take (LOT) systems. This shift aims to eliminate fuel waste that currently costs the nation an estimated ₹21,900 crore every year by ensuring nearly all gas in the cylinder is utilized.
India’s state-owned oil marketing companies are leading a strategic push to modernize how commercial and industrial businesses use Liquefied Petroleum Gas. The industry is moving to replace conventional vapour off-take cylinders, which have been the standard for nearly twenty years, with liquid off-take or LOT systems. The transition is aimed at solving a long-standing issue of fuel inefficiency in the commercial sector.
Why Conventional Cylinders Cause Waste
Standard cylinders often fail to utilize the entire volume of gas. Because these cylinders release gas in vapour form, approximately 1 kg of fuel remains trapped as liquid at the bottom of a 19-kg cylinder when the pressure drops. Across the millions of cylinders used daily by restaurants, hotels, and factories, this adds up to about 4,000 tonnes of wasted LPG every single day. Over a year, this waste reaches 1.46 million tonnes, a significant volume that contributes to higher import requirements for India.
Economic and Strategic Benefits
By adopting LOT systems, which are designed to withdraw fuel in its liquid state, businesses can effectively use the entire contents of a cylinder. According to inputs provided to the Ministry of Petroleum and Natural Gas, this transition has the potential to generate annual savings of approximately ₹21,900 crore for the nation. Beyond the direct cost benefits, improving fuel efficiency helps reduce the country’s reliance on imported energy, which is a major focus given current global geopolitical pressures.
Challenges in Adoption
Although LOT technology has been available in the Indian market since 2007, adoption remained slow for many years due to a lack of active promotion and awareness. Businesses have historically preferred the older, familiar vapour-based systems. However, with oil marketing companies now actively supporting the conversion, the initiative has reached over 1,000 businesses across the country. The shift is also being positioned as a safety upgrade, as LOT systems are engineered to handle industrial requirements more effectively than standard cylinders.
What Investors Should Monitor
For investors, the success of this transition will depend on the pace of conversion among the 4 million daily commercial users. Key factors to track include the speed at which oil marketing companies update their supply infrastructure and whether the government introduces further incentives or mandates to accelerate the phase-out of older cylinder types. The move could eventually reflect in the operational efficiency of oil marketing companies by reducing the logistics and procurement overhead associated with wasted fuel volumes, though the immediate impact on profit margins will depend on the cost of implementation versus the realized savings.
