Overview

Gas-Union GmbH is a German wholesale company for natural gas operating in the German market, with its registered office in Frankfurt am Main. It is a subsidiary of the internationally active energy group VNG AG, based in Leipzig, to which it has belonged since 1 October 2020. The company's core business is the wholesale trading of natural gas, supplying regional and local distribution network operators as well as industrial end consumers. Historically, Gas-Union's activities extended beyond pure trading into gas storage and gas transport. Its storage activities were to be taken over by MET Holding AG, a Europe-wide energy group headquartered in Zug, Switzerland, with the purchase agreement signed on Thursday, 19 November 2020. Its transport activities were bundled in the subsidiary Gas-Union Transport GmbH, which until December 2020 operated the regional natural gas transport system of Gas-Union GmbH with a total length of approximately 544 km. In December 2020, the independent transmission system operator terranets bw GmbH acquired Gas-Union Transport GmbH and merged it into itself. The transport system was connected to local and regional distribution network operators as well as industrial end consumers, and was assigned to the market areas of NetConnect Germany and Gaspool. Following these divestments, Gas-Union continues as a natural gas wholesaler within the VNG group. Its public communications emphasize corporate management, sustainability and a corporate mission statement (Leitbild), alongside its service catalogue and press releases.

History

Gas-Union GmbH is a German natural gas wholesale company headquartered in Frankfurt am Main. Its core business is the wholesale trading of natural gas on the German market. The company supplies regional and local gas distribution network operators as well as industrial end consumers. A major turning point came in 2020, when Gas-Union was integrated into the internationally active energy group VNG AG, based in Leipzig. Since 1 October 2020, Gas-Union GmbH has belonged to VNG AG. In the same period, the company divested two of its historical business segments.

The purchase agreement was signed on Thursday, 19 November 2020. Second, its gas transport activities were bundled in the subsidiary Gas-Union Transport GmbH. Until December 2020, this subsidiary operated the regional natural gas transport system of Gas-Union GmbH, with a total length of approximately 544 km. The system was connected to local and regional distribution network operators as well as industrial end consumers, and was assigned to the market areas of NetConnect Germany and Gaspool. In December 2020, the independent transmission system operator terranets bw GmbH acquired Gas-Union Transport GmbH and merged it into itself. After these transactions, Gas-Union continued as a natural gas wholesaler within the VNG group.
