Tüpras enjoys a unique position as the only refiner in one of the last remaining growth markets in Europe. Moreover, Tüpras and its marketing affiliate Opet together control around two thirds of Turkey's total oil storage capacity. This further strengthens the company's influence on supply and wholesale market prices, given the relative lack of independent oil product import infrastructure in the country. The company's new upgrading units were commissioned during 2015, contributing to its strong financial performance in a year of record-high refining margins. However, currently under construction Aliaga refinery in Izmir will provide a strong competition to Tupras from 2018.
