  • About us

    Open Grid Europe, with its head office in Essen, has a transmission pipeline network spanning 12,000 kilometres, making it one of the biggest in Germany. With our 1,650 staff we offer decades of experience in natural gas engineering, operation and marketing.

  • Our core business

    Jeder, der mit Erdgas handelt, ist unser potenzieller Kunde. Wir bieten den Transport von Erdgas durch unser rund 12.000 km langes Ferngasnetz in Deutschland an. Das ist unsere Kernleistung.

  • Affiliated companies

    Part of our gas transmission network consists of pipelines belonging to pipeline companies which we co-own together with partner companies.

As an independent transmission system operator we were established as a subsidiary of E.ON Ruhrgas in 2004. In the meantime we have advanced to become Germany's leading natural gas transporter with a workforce of around 1,450 and 450 international and national customers.


1926
The 'Aktiengesellschaft für Kohleverwertung (AGKV)' – later to become Ruhrgas – is founded with the idea of using the coke oven gas released during the production of coke for large-scale long-distance gas supplies. The new company proposes to combine the mines that produce the gas into a network, and looks for customers among local authorities, towns and industrial companies interested in receiving supplies of piped gas.

1931
Just five years after it is founded, Ruhrgas is Germany's biggest gas supplier – the idea of piped gas has become widely accepted. 26 mines are now feeding almost 800 million cubic metres of coke oven gas into a gas transmission network which is already 933 km long.

1964
Ruhrgas commences the phased conversion of its transmission networks from town gas to natural gas – domestic appliances and industrial furnaces are also upgraded. Work on converting the pipeline system to natural gas operation continues well into the seventies.

1973
The German section of TENP, the trans-European pipeline running from the Netherlands through Germany to Switzerland and on to Italy, is commissioned.

1981
The completion of the MEGAL pipeline from Northern Bavaria to the Saarland is the final link in the European natural gas network – with it, Ruhrgas has made a major contribution to Europeanising the supply of natural gas.

2003
Ruhrgas merges with E.ON.

2004
Ruhrgas-Transport is established as a gas transmission subsidiary of E.ON Ruhrgas and in 2006 is renamed E.ON Gastransport.

2007
Launch of the biggest entry/exit system: October 2007 sees the three H-Gas market areas merge to form one of Europe's biggest entry/exit systems and one which allows energy traders to book capacities at entries and exits irrespective of the transmission route.

2008
E.ON Gastransport acquires the ownership of E.ON Ruhrgas networks in Germany.
On 1 October 2008 the two gas transmission companies E.ON Gastransport and bayernets establish NetConnect Germany (NCG) and merge their H-Gas market areas to create the first market area co-operation in Germany. Responsibility for balancing group management and for operating the virtual trading point is now taken over by NCG.

2010
Our starting signal: Open Grid Europe (formerly E.ON Gastransport) launches in early September 2010 as an independent transmission system operator.

2011
The first market area in Germany to handle different grades of natural gas is launched at the initiative of Open Grid Europe: the market areas of Open Grid Europe L-Gas, Thyssengas H-Gas and Thyssengas L-Gas are merged with the existing market area of NetConnect Germany (NCG) on 1 April.

2012
23 July 2012 sees the completion of the sale of Open Grid Europe to Vier Gas Holdings Sarl in Luxembourg, ultimately held by a consortium consisting of the Macquarie European Infrastructure Fund 4, Infinity Investments, British Columbia Investment Management Corporation and MEAG MUNICH ERGO Asset Management.

2013
By decision of 2 December 2013 the Federal Network Agency certified Open Grid Europe as Independent Transmission Operator (ITO). Open Grid Europe has thus successfully demonstrated that its structures comply with the unbundling requirements of the German Energy Industry Act.
