GAIL (India) Limited has escalated its long-standing dispute with the Petroleum and Natural Gas Regulatory Board (PNGRB) by filing a petition in the Delhi High Court against the regulator's unbundling directive. This directive, which mandates separating gas transportation from marketing activities, was originally proposed in 2017 but has yet to be implemented. GAIL contends that unbundling threatens its integrated business model, which has been built on its extensive pipeline network of approximately 16,000 km, constituting 59% of India's authorized pipeline infrastructure. The company argues that the Indian gas market is still evolving and not ready for such a split, claiming that it could weaken both sectors and benefit private players at the expense of public sector undertakings. The PNGRB, frustrated with GAIL's resistance, has received backing from a committee report led by Ajay Tyagi, which emphasizes the need for reform in the now-mature market. The ongoing legal battle highlights the tensions between a state-run entity and its regulatory body over the future structure of India's gas market.
