₹2,449 crore, 425 kilometres, and one goal: rescuing a Kochi LNG terminal that has run at just 15-25% capacity for over a decade.
NEW DELHI: The Board of Directors of Indian Oil Corporation Limited approved an investment of ₹2,448.70 crore on September 21, 2026 to build the Kochi–Kanyakumari–Thoothukudi Natural Gas Pipeline, a 424.65-kilometre trunk line designed to extend India’s national gas grid into a stretch of the peninsula that has remained disconnected from it for years. The project will be executed directly by IOCL as a Maharatna public sector undertaking, without a joint venture or special purpose vehicle.
The approval follows a regulatory process that began with a competitive tender in October 2024, after which the Petroleum and Natural Gas Regulatory Board authorised IOCL to build and operate the pipeline in April 2026. The line will originate at Petronet LNG’s regasification terminal in Puthuvype, within Kochi’s Special Economic Zone, and travel south through Kottayam, Kollam and Thiruvananthapuram districts in Kerala, before crossing into Tamil Nadu through Nagercoil and terminating at the industrial port city of Thoothukudi.
Fixing a Decade-Old Bottleneck
The pipeline’s most immediate purpose is solving a long-standing underutilisation problem at Petronet’s Kochi terminal. Commissioned in August 2013 with a nameplate capacity of 5 million tonnes per annum, the facility has typically operated at just 15% to 25% of capacity for over a decade, largely because the downstream pipeline network needed to carry that gas onward was never built. In the interim, the terminal has relied on stopgap measures including cryogenic LNG truck filling under its Taral brand and ship-to-ship bunkering services, despite holding a long-term supply contract for 1.4 million tonnes annually from ExxonMobil’s Gorgon project in Australia. The new pipeline is designed to give the terminal a proper evacuation corridor, carrying up to 6.84 MMSCMD of regasified gas southward.
Beyond the terminal itself, the project addresses a broader regional gap. India’s gas pipeline infrastructure has historically clustered around the west and north, anchored by corridors like the Hazira–Vijaipur–Jagdishpur line and coastal terminals in Gujarat and Maharashtra. While northern Kerala gained connectivity through GAIL’s Kochi–Koottanad–Bengaluru–Mangaluru pipeline, the region south of Kochi has remained cut off from high-pressure gas infrastructure entirely, a gap this project is meant to close.
The Engineering and the Economics
At ₹2,448.70 crore for 424.65 kilometres, the project works out to a capital intensity of roughly ₹5.77 crore per kilometre, a figure that reflects the practical difficulty of laying pipe through densely populated Kerala and Tamil Nadu, including river crossings via horizontal directional drilling and land acquisition under Right of User frameworks. As mandated by PNGRB rules, a minimum of 25% of the pipeline’s throughput, or 1.71 MMSCMD, must remain available as common carrier capacity, allowing third-party gas marketers and city gas distributors to book transportation space without building competing infrastructure of their own.
IOCL is funding the project entirely through internal accruals and corporate debt, without government viability gap funding, folding it into a FY27 capital expenditure budget of ₹32,700 crore. The project will earn regulated returns through PNGRB’s discounted cash flow tariff methodology rather than open market pricing, a structure that gives IOCL predictable, if modest, cash flows insulated from crude oil price swings that currently affect over 90% of its revenue through refining and fuel marketing.
Building Redundancy Across the Coast
Perhaps the more strategically interesting element is what this pipeline does once it reaches Thoothukudi. IOCL already operates the Ennore–Tuticorin–Bengaluru pipeline system on Tamil Nadu’s east coast, with a capacity of 34.67 MMSCMD. By extending KTPL to Thoothukudi, IOCL effectively links the Kochi LNG terminal on the Arabian Sea with its existing Ennore network on the Bay of Bengal, creating a dual-feed loop that can reroute gas supply in either direction depending on demand or disruption. For industrial clusters in southern Tamil Nadu, that redundancy offers a meaningful supply security upgrade over relying on a single source.
What Could Slow It Down
The project’s most likely bottleneck lies in securing Right of User land permissions, particularly in Kerala’s densely populated districts, where similar pipeline projects, including GAIL’s KKBMPL, have previously faced delays pushing completion targets back. To address this, the government issued a control order under the Essential Commodities Act in March 2026, mandating standardised timelines and deemed approvals for right-of-way permissions, though whether this actually accelerates ground-level execution remains to be seen. Notably, IOCL’s stock exchange disclosure did not specify a construction schedule or a target commercial operation date, leaving the project’s timeline genuinely open for now.
What to Watch
Several markers will indicate how smoothly the project moves from paper to pipeline. These include the issuance of statutory gazette notifications establishing formal right-of-way access across Kerala and Tamil Nadu districts, the award of engineering contracts for line pipe procurement and directional drilling, progress on the physical tie-in at Petronet’s Puthuvype terminal, and the signing of long-term gas transmission agreements with industrial users or city gas operators that would lock in demand ahead of first gas. Until those pieces fall into place, KTPL remains a well-funded and clearly justified project on paper, with its real test still ahead on the ground.
