Gas Networks Ireland expects continued gas flows from Corrib field in the Slyne Basin.
It also has access to UK resources through a series of subsea pipelines to Great Britain and the Isle of Man.
The UK interconnector accounts for roughly 70% of Irish gas consumption.
Maurice Power, future networks manager at Gas Networks Ireland, said:- Irish natural gas demand was expected to fall in the current summer season year/year, due to higher wholesale gas prices and reduced heating demand
Last year, natural gas met 69% of Ireland's daily electricity needs.
Power noted:
- Based on the assessment of all supply sources to Ireland and anticipated demand levels, it is not envisaged that there will be a disruption to Ireland's gas supply during the summer months
Shell developed the project, which launched in 2015, but sold its stake to the pension board 3 years later.
The UK major anticipated peak production of around 260 mln ft3/day, however the field has since entered decline.
