Notes to Editors:

Background on Infrastrata plc

Infrastrata's business is focused on the development of two gas storage projects in the United Kingdom at Portland, Dorset and at Islandmagee, County Antrim, Northern Ireland. The two projects could between them provide over 10% of the total UK and Ireland peak daily demand in the latter part of the next decade. The Company is also developing new projects in mainland Europe initially focussing on Germany and Spain. The Company is one of only a few in Europe focused specifically on gas storage development, a sector with significant growth potential in Europe over the coming decades. In December 2009 the name of the Company was changed from Portland Gas plc.
