 As with electricity , the natural gas distribution network is also now all @-@ island , with a pipeline linking <unk> , County Meath , and <unk> , County Antrim completed in 2007 . Most of Ireland 's gas comes through <unk> between <unk> in Scotland and <unk> , County Antrim and <unk> , County Dublin . A decreasing supply is coming from the <unk> gas field off the County Cork coast and the <unk> Gas Field off the coast of County Mayo has yet to come on @-@ line . The County Mayo field is facing some localised opposition over a controversial decision to refine the gas onshore .
