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