HelleniQ Energy Holdings S.A.
Energy
HelleniQ Energy, formerly Hellenic Petroleum, is Greece's largest energy group and one of Southeast Europe's leading oil and gas companies, founded in 1998 from the consolidation of Greece's state petroleum assets. Headquartered in Athens, the group employs about 3,000 people and generates annual revenue of roughly EUR 12 billion, operating refineries, a petrochemical complex, and a fuel retail network across Greece, Cyprus, Bulgaria, and North Macedonia.\n\nThe group's three refineries — Aspropyrgos, Elefsina, and Thessaloniki — have a combined capacity of about 15 million tonnes per year and are among the most complex in the Mediterranean, able to process heavy and sour crudes into high-value products including fuels, bitumen, and lubricants. Its retail network operates more than 1,500 service stations under the EKO and Hellenic Petroleum brands, and its DESFA stake and gas trading activities make it a key player in the Eastern Mediterranean energy corridor. HelleniQ Energy is also investing in renewables, green hydrogen, and a major effort to upgrade its refineries to produce sustainable aviation fuel.\n\nFor buyers in the Eastern Mediterranean and Balkans, HelleniQ Energy is the anchor supplier of fuels and petrochemicals, with deep logistics integration across ports, pipelines, and storage — and a growing procurement pipeline for refinery modernization and renewable-energy equipment.
