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.
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.
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.
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.
The German section of TENP, the trans-European pipeline running from the Netherlands through Germany to Switzerland and on to Italy, is commissioned.
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.
Ruhrgas merges with E.ON.
Ruhrgas-Transport is established as a gas transmission subsidiary of E.ON Ruhrgas and in 2006 is renamed E.ON Gastransport.
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.
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.
Our starting signal: Open Grid Europe (formerly E.ON Gastransport) launches in early September 2010 as an independent transmission system operator.
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.
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.
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.
