Overview
Prometheus Gas S.A. is a Greek-Russian natural-gas company established in Athens in 1991. The company was formed as a joint venture between Gazprom Export, acting on behalf of Gazprom, and the Copelouzos Group. According to the referenced Wikipedia material, each side holds 50% of the company. The Copelouzos-side shareholder is identified as Dimitrios Ch. Copelouzos, chairman and managing director of the Copelouzos Group. The company's principal business has been the importation and marketing of Russian natural gas in the Greek market. Its role has extended beyond commodity supply: Prometheus Gas has also been associated with the development of gas infrastructure, including transmission pipelines, compressor stations, and urban natural-gas distribution networks. This positioned the company within the broader process of expanding natural-gas use in Greece and building the physical systems needed to transport and distribute the fuel. Another part of the company's stated business scope has been the promotion and implementation of projects intended to create large new natural-gas consumers. These projects included modern combined-cycle power stations fueled by natural gas. Such facilities can serve as anchor customers for gas-import and transmission systems, linking fuel supply with electricity-generation development. The referenced material also describes Prometheus Gas as having secured, through Gazprom, substantial gas quantities beyond the volumes contracted for import into Greece by the state utility DEPA. The cited supply arrangements were described as providing 3 billion cubic meters annually until 2016 and 7 billion cubic meters annually after that period. These figures describe contractual or secured supply capacity in the historical source material, not necessarily current deliveries or present-day operating volumes. Publicly available information supplied for this entry is limited and primarily describes the company's historical ownership, activities, and supply arrangements. No reliable current website, listing information, current executive roster, updated ownership status, or present operating status has been provided. Accordingly, Prometheus Gas is best documented here as a natural-gas import and infrastructure company with a Greek market focus, while its current corporate position remains unverified.
History
Prometheus Gas was established in Athens in 1991 as a Greek-Russian joint company. Its ownership structure linked Gazprom's export organization with the Copelouzos Group: the referenced Wikipedia article identifies Gazprom Export, acting for Gazprom, as holding half of the shares, while Dimitrios Ch. Copelouzos held the remaining half. This structure gave the company a direct connection to Russian gas exports and to a Greek business group with interests in energy and infrastructure. The company's core activity was the importation and marketing of Russian natural gas in Greece. Its business was therefore tied to the development of the Greek gas market, including the expansion of demand among industrial, commercial, and power-generation customers. Prometheus Gas was also described as participating in the development of the infrastructure required to make natural gas available, including transmission pipelines, compressor stations, and urban distribution networks. Infrastructure and demand creation were treated as related areas of activity. The company promoted and implemented business plans intended to establish major new gas consumers, especially modern combined-cycle power stations using natural gas. These projects could increase gas demand while supporting the wider development of Greece's electricity and gas systems. The supplied historical reference states that Prometheus Gas secured, through Gazprom, gas volumes in excess of the quantities contracted for import into Greece by the state utility DEPA. The cited arrangements amounted to 3 billion cubic meters per year through 2016 and 7 billion cubic meters per year after that point. These statements are historical descriptions of secured supply arrangements and should not be interpreted as confirmation of current volumes. The available source material does not provide a sufficiently detailed account of later ownership changes, new infrastructure projects, financial performance, current leadership, or the company's present operating status. Prometheus Gas's documented history is consequently centered on its 1991 formation, its Greek-Russian ownership model, its role in Russian natural-gas imports, and its involvement in the infrastructure and power-generation projects that supported the expansion of natural gas in Greece.
