Common interest projects

Physical Reverse Flow at Moffat

The interconnection point at Moffat is currently uni-directional with gas flow from the United Kingdom to Ireland. Project PCI 5.1.1 would make the Moffat interconnection point bi-directional.

Completed projects

Gas Networks Ireland constructed a 2.6km pipeline to deliver natural gas to the new IDA Industrial Park at Haynestown, Dundalk Co. Louth. The pipeline also served to reinforce the gas supply to Dundalk town. The project also involved the construction of a new Above Ground Installation (AGI) at Haynestown. An AGI site contains filtering, metering and pressure reduction equipment and will be landscaped to blend in with the surrounding area.

This project was required to reinforce the supply of natural gas to the north side of Dublin City, namely the Eastwall, Fairview, Marino, Donnycarney, Artane and Coolock areas

Gas Networks Ireland designed a pipeline to bring natural gas to Great Island, Co. Wexford, where Endesa Ireland constructed a new power generating station on the site of the existing power station. The pipeline was taken from the Cork Dublin pipeline, at Baunlusk, Co. Kilkenny to Great Island, Co. Wexford and consisted of a 45km 400mm high grade steel pipeline buried to a minimum depth of 1.2metres.

Pipeline construction commenced in September 2012 and was mechanically completed by autumn 2013. Reinstatement continued into 2014, where weather conditions required. The project also required the construction of three new Above Ground Installations (AGI) along the route. An AGI site contains filtering, metering and pressure reduction equipment, these are landscaped to blend in with the surrounding area.

The Interconnector 2 was identified as the most practical solution to transport additional gas supplies from Beattock, Southwest Scotland to Gormanstown, Co. Meath, Ireland. The 195km sub-sea pipeline is built from high grade steel with anti-corrosion and anti-buoyancy coatings. The project required a wide range of approvals from the jurisdictions of Ireland, Scotland and the Isle of Man. It was constructed onboard the Solitaire vessel using an automated welding system, completing up to 8 kilometres per day.

The project also consisted of the following:

  • An 11km sub-sea spur-line, to supply gas to the Isle of Man
  • A 30km on-shore pipeline from Brighouse Bay
  • An extension of the existing compressor stations at Beattock and Brighouse
  • A reception terminal at Gormanstown
  • A 14km pipeline linking Gormanstown with the existing network at Ballough
  • 3 Above Ground Installations (AGI) located along the route

It was completed on schedule in November 2002.

Studies were undertaken to evaluate the extension of the natural gas network to additional towns around the country . In 2006, Phase 1 of the New Towns Report found 11 towns on the route of the Mayo-Galway pipeline were viable for connection. The majority of these towns have been connected, with Tuam and Athenry due to be connected. Please see further details in our Gaswest section.

Phase 2 of the study was completed in 2007, with a further 6 towns qualifying for connection. Further information is available in the New Towns Phase 2 Report (due to the size of these files the report has been split into 7 parts):
