Baku, August 28, 2025 — The STAR oil refinery, a key asset of Azerbaijan’s state oil company SOCAR in Turkey, has reported a significant increase in diesel production during the first half of 2025.
According to data from Turkey’s Energy Market Regulatory Authority (EPDK), the refinery produced more than 3.34 million tons of diesel between January and June, marking a 6.97% rise compared to the same period last year — an additional 217,984 tons.
The growth trend was particularly striking in June, when STAR refined over 527,978 tons of diesel, up 65.6% from June 2024.
Overall, Turkish refineries produced approximately 8.37 million tons of diesel in the first six months of 2025, up 5.1% year-on-year, with June output alone climbing 11.4% to about 1.4 million tons.
Analysts note that the STAR refinery — one of the most advanced energy projects in Turkey with strong Azerbaijani investment — continues to play a vital role in both meeting domestic fuel demand and strengthening SOCAR’s strategic footprint in the Turkish energy market.
