** The Manx Electricity Authority only had responsibility for the supply of electricity. These responsibilities were extended in 2003 to include the supply of gas. This was in conjunction with the construction of high pressure natural gas import system from the UK-Ireland gas interconnector. The Gas and Electricity Act 2003 empowered the Manx Electricity Authority to supply gas, and to construct pipes and associated apparatus (Section 1); it also had the duty to supply gas to other organisations such as public gas suppliers (Section2).
