PetroChina will undertake a two-month maintenance shutdown of its 13 million metric tons per year Yunnan petrochemical plant from November 15, 2025, to January 15, 2026. This extensive overhaul will temporarily halt production of key refined products, including gasoline, diesel, and jet fuel, which are crucial for Southwestern China and Southeast Asia. While the company plans operational and supply adjustments, the significant downtime of this major facility could tighten regional refined product markets and influence pricing during the period.
PetroChina has announced a comprehensive two-month maintenance shutdown for its 13 million metric tons per year Yunnan petrochemical plant, scheduled from November 15, 2025, to January 15, 2026. This extensive overhaul, encompassing approximately 23,000 tasks, signifies a substantial investment in the asset's integrity, which is a key producer of China VI-standard gasoline, diesel, and jet fuel. The Yunnan refinery is a critical supplier to Southwestern China and Southeast Asia, having processed 11.56 million tons of crude and produced 11.15 million tons of products in 2024. While PetroChina plans operational and supply adjustments, the temporary removal of this significant capacity is likely to tighten regional refined product markets during the maintenance window. The timing of this maintenance is strategically based on unit operating conditions to ensure safe, reliable, and efficient operations post-overhaul. This proactive approach, while creating short-term supply considerations, underscores PetroChina's commitment to long-term operational stability and efficiency, which is crucial for its downstream segment.
