Overview

Central Energy Italian Gas Holding, also referred to in available material as Central Energy Italian Inc and by the abbreviation CEIGH, was an Italian company involved in gas distribution and gas trading. The company was associated with Central Energy, which reference material describes as being related to Gazprom. Its public profile emerged principally from a proposed gas-supply arrangement involving Italy’s Eni and Gazprom, under which CEIGH was selected as a partner for delivering gas into the Italian market. Rather than becoming known through consumer marketing or a broad portfolio of branded energy products, CEIGH became notable because of the ownership and political questions surrounding the proposed arrangement. Investigations by members of the Italian Parliament reported that Bruno Mentasti-Granelli, described as a close associate of then-Italian Prime Minister Silvio Berlusconi, held 33 percent of the company through two entities named Hexagon Prima and Hexagon Seconda. The reported ownership structure prompted scrutiny over whether political connections and private financial interests were influencing an important international gas contract. The proposed Eni–Gazprom arrangement, with CEIGH as an Italian commercial partner, was denounced amid the resulting controversy. The Italian Parliament blocked the contract after allegations that Berlusconi could have had a personal interest in the transaction. The affair was therefore discussed not only as an energy-supply matter but also as a case involving political influence, corporate opacity, and the strategic role of Russian-linked gas interests in Italy. Available reference material also identifies Robert Nowikovsky, an Austrian lawyer linked in reporting to Russian operations, as one of CEIGH’s directors. This added to the company’s association with cross-border legal, financial, and energy networks connected to the proposed deal. A 2008 commentary further connected the matter with Centrex, Hexagon 1 and 2, and Gazprom, although the supplied material does not establish a complete corporate history or the company’s later operating status. There is insufficient reliable information in the supplied sources to establish CEIGH’s founding year, detailed operations, subsequent ownership, financial performance, current activities, or whether it remains active. Its documented significance lies primarily in the failed Italian gas partnership and the political and governance controversy surrounding that proposal.

History

Central Energy Italian Gas Holding was an Italian gas distribution and trading company associated with Central Energy. The available account describes Central Energy as a company related to Gazprom, placing CEIGH within a network of enterprises connected to Russian gas interests. The company’s documented public importance arose from a proposed commercial arrangement rather than from a long record of consumer-facing operations. Eni and Gazprom developed a gas-supply arrangement in which CEIGH was selected as a partner responsible for delivering gas to Italy. The proposal attracted political and media attention because the ownership structure of the Italian partner was not viewed as commercially neutral. Investigations by members of the Italian Parliament reported that Bruno Mentasti-Granelli owned 33 percent of CEIGH through two companies, Hexagon Prima and Hexagon Seconda. Mentasti-Granelli was publicly known as a close friend of Silvio Berlusconi, who was serving as Italian prime minister at the time. The reported connection generated allegations that the proposed gas contract could serve private or political interests in addition to its stated energy purpose. Critics questioned the transparency of the corporate structure and the role of politically connected individuals in a strategically significant gas transaction. The arrangement was denounced amid the controversy, and the Italian Parliament blocked the contract after accusing Berlusconi of having a personal interest in it. The company was also associated with Robert Nowikovsky, an Austrian lawyer identified in the available material as one of its directors and described as having links to Russian operations. Later commentary connected the CEIGH affair with Centrex, Hexagon 1 and 2, and Gazprom. These references framed the proposed transaction within wider concerns about Russian influence in European energy markets and about the use of intermediary companies in cross-border gas deals. The supplied sources do not provide a verified founding date, a complete list of shareholders, details of CEIGH’s gas infrastructure, evidence of substantial completed deliveries, financial statements, or a clear account of its activities after the blocked contract. They also do not establish whether the company was dissolved, renamed, or remained operational. Accordingly, CEIGH is best documented as an Italian gas trading and distribution company whose principal recorded episode was the failed Eni–Gazprom-linked arrangement and the political scandal surrounding it.
