The Rough resevior was shaped naturally by rock formations over 200 million years ago. This time look looks at its more recent commercial history. 


2001 - BG Storage sold Rough storage to Dynegy

2002 - Centrica acquired the Rough storage assets from Dynegy for £304m 

2003 - Following a Competition Commission inquiry into the acquisition, Centrica provided the Department of Trade and Industry and Ofgem with a set of Undertakings. Centrica Storage Limited was created as a business unit, legally, finically and physically separate from the rest of Centrica. Centrica Storage Limited became a wholly owned subsidiary of Centrica plc 


1997 - BG Storage was established as a stand-alone business (it was separated from the rest of British Gas plc for competition reasons).



1980 - BG Corporation (which became British Gas plc in 1986 following privatisation) purchased the Rough field with about one-third of the reserves depleted. 

1983/4 - British Gas decided to convert the field into a natural gas storage facility 

1985 - The gas storage facility became operational, enabling gas to be stored in the reservoir some 2,700 meters under the seabed.


Rough offshore facilities and Easington terminals were developers to produce and process natural gas from the Rough field 



Licences for the Rough field were awarded to Gulf Oil, the Gas Council, Amoco Group, Amerada Hess and the North Sea Inc
