The Oil and Gas Sector in Athens
Although Greece is not a major oil producer, it plays an important role in the regional energy system. The country hosts large, modern refineries that export fuels throughout the Mediterranean, an extensive natural gas network, liquefied natural gas terminals and strategic pipelines connecting Europe to new supply sources. Athens and the nearby industrial areas of Aspropyrgos, Elefsina and Corinth are the center of this activity.
Many of these companies are also investing heavily in renewable energy, reflecting the broader energy transition. Below are ten of the most significant oil and gas companies based in or operating from Athens.
