AOT Energy is a private, global energy trading company which traces its origins back to 1947, when Baron FRÈRE founded TRANSCOMETAL to service the steel industry. Since then the TRANSCOR GROUP expanded from coal into crude oil and oil products with the acquisition of the international brand “ASTRA” in the 1980’s. In more recent years ASTRA expanded into petrochemicals, renewables and gas.

AOTH and its trading subsidiaries conduct business under the new brand name of AOT ENERGY. The Group Management of AOT ENERGY operates from headquarters in Steinhausen, Switzerland.
