Background on the Islandmagee Storage Project

The Islandmagee gas storage project company, Islandmagee Storage Limited ("IMSL"), is owned 90% by a wholly owned subsidiary of InfraStrata plc and 10% by a wholly owned subsidiary of Mutual Energy Limited. The project is a proposed salt cavern gas storage facility located on Islandmagee in County Antrim, Northern Ireland. Work commenced in 2007 with the acquisition of 3D seismic data to image the Permian salt in the Larne Lough area. During 2012, planning permission was granted for the project and a gas storage licence was issued by the Utility Regulator. In 2015 a well was drilled to core the salt and confirm the technical feasibility of the project, supported in part by the Commission. To date approximately £11m has been invested in the project.
