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 Company is also developing new projects in mainland Europe initially focussing on Germany and Spain.

Further information is available on the Company's website www.infrastrata.co.uk.

Background on the Islandmagee Storage Project

The proposed 500 million cubic metres ("mcm") facility will be the largest on the island of Ireland and the first for Northern Ireland. A planning application for the project was submitted to the Strategic Projects Unit of the Northern Ireland Planning Service in March 2010. The facility is being designed to inject gas at 12 mcm and withdraw gas at 22 mcm per day. The cost of construction has been estimated at circa £250 million, including cushion gas. The project is owned by Islandmagee Storage Limited an independent Northern Ireland registered company; a joint venture between Infrastrata UK Limited (part of the Infrastrata plc group of companies) - 65% shareholder and Moyle Energy Investments Limited (part of the Mutual Energy group of companies) - 35% shareholder. Moyle Energy Investments Limited will require Regulatory approval to participate in the construction of the project; in the meantime Infrastrata UK Limited is providing 100% of the development capital via shareholder loans.

Background on Mutual Energy Limited ("MEL")

MEL is a company limited by guarantee. Its principal objective is to own and operate energy infrastructure assets in the interests of the energy consumers of Northern Ireland. The company is a mutualised entity and therefore has no shareholders and its primary stakeholders are energy consumers.
