Gas Infrastructure

The importance of maintaining investment in Ireland’s gas network

The national gas network must be capable of maintaining an acceptable level of service in the face of faults or other abnormal conditions such as very cold weather. Given that gas network development projects take a number of years to complete, maintaining a steady level of development and renewal is essential to ensure having a network that is safe, resilient and of sufficient capacity to meet peak demands, in the medium to longer term.

Security of gas supply

Gas is supplied to three categories of customer; electricity generation, large industry and SME/domestic. 62% of this gas comes from Britain via two subsea interconnectors linking Scotland to Ireland. This infrastructure also serves the Scotland/Northern Ireland Pipeline which meets 100% of Northern Ireland’s gas needs. Remaining gas demand of, around 38%, is met by gas production from the Kinsale (4%) and Corrib (34%) gas fields.

The importance of diversifying sources of Ireland’s gas supplies

Ireland’s reliance on imported gas has significantly reduced with the coming ashore of indigenous gas from Corrib (production commence in late 2015). While Britain will remain a key source of gas supply for Ireland, Ireland’s security of supply of both gas and electricity has greatly improved by the production of gas from the Corrib field.

Since the start of 2016, Corrib production accounts for approximately 34% of gas demand. It is expected that this will rise to approximately 60% in 2016/2017 and approximately 50% in 2017/18. Thereafter production is expected to decline.
