Indian Refiners Push Past Nameplate Capacity as Diesel Demand Climbs
India’s refining sector has been operating well above its stated design limits, with utilization rates reaching 105% to 108% over the past six months, according to a senior executive at state-run Mangalore Refinery and Petrochemicals Limited (MRPL). The executive shared the figures at the APPEC petroleum conference in Singapore this week.
Sustained operation above nameplate capacity — the maximum throughput a refinery is engineered to handle — is unusual but achievable for so-called complex refineries. These facilities use advanced conversion units such as fluid catalytic crackers and cokers, allowing them to process heavier, discounted crude grades and squeeze a higher share of valuable products like diesel and jet fuel out of each barrel. India’s refining fleet is dominated by such complex configurations, which is why operators can stretch past 100% utilization.
The output surge reflects two converging pressures. Domestically, diesel demand — a key indicator of economic activity in India, fueling trucks, agriculture, and industry — has climbed sharply. Internationally, product markets have tightened as the Middle East conflict disrupts trade flows, prompting buyers to seek supply from large refining hubs. India, the world’s third-largest crude oil importer, has become an increasingly important exporter of refined products to Europe and Asia as alternative supply chains adjust.
Running refineries this hot supports downstream product exports, which in turn depends on product tanker shipping capacity. One listed player in that midstream — shipping — space is International Seaways (INSW), which operates a fleet of crude and product tankers. INSW shares traded at $103.81 on Wednesday, down 0.48% from the prior close of $104.31, giving the company a market capitalization of roughly $5.14 billion.
For Indian refiners, extended over-capacity operation also raises questions about maintenance scheduling and margin capture, since strong refining margins (the spread between crude input costs and product sale prices) incentivize maximizing runs even at the cost of deferred turnaround work. MRPL and other state-linked refiners have not indicated any change to their operating plans in public remarks.
What to watch
- Monthly refinery throughput and diesel export data from Indian state refiners, including MRPL and peers.
- Upstream crude import volumes, which signal whether elevated run rates can be sustained.
- Product tanker rates and shipping demand as Middle East trade patterns continue to shift.
- Any scheduled maintenance announcements that could trim utilization in coming quarters.
