Gas Networks Ireland has launched a €50 million upgrade project to strengthen the high-pressure gas transmission network in the southern region.

The initiative is designed to address projected capacity constraints and ensure a reliable energy supply, particularly during extreme weather events.

The project is expected to increase pipeline capacity in the Southern area by approximately 20 per cent. This reinforcement will help the national grid meet peak demand—specifically targeting a "1-in-50 year winter day" scenario—while supporting regional economic growth and the connection of new commercial customers and flexible power generation.

Key Project Details:

• Capacity Growth: A 20 per cent increase in Southern network capacity.

• Economic Impact: Facilitates continued industrial growth and flexible gas-fired power generation.

• Timeline: Construction began earlier this month at existing sites in Dublin and Limerick, with the new capacity expected to be operational by next winter.

• Delivery Partners: The project is being delivered in collaboration with construction partner Murphy.

Gas Networks Ireland Chief Executive, David Kelly, stated: "This project represents a critical investment in our network and comes at a time when energy supply and security is a significant issue for the Irish economy. Without this investment, we run the risk of future capacity constraints in the Southern area of our network, making this a priority national project."

Brian Sheehan, Director of Assets & Infrastructure, noted that the project is being expedited to prevent energy curtailment in the South, adding: "While counties along the pipeline route will directly benefit, this reinforcement project will also prevent capacity issues and constraints in other parts of the network, thereby benefitting the whole country in the longer term."

This investment follows the company's recent announcement of a separate €200 million plan to decarbonise its Scottish compressor stations. By installing new Electric Motor Drives (EMDs), Gas Networks Ireland aims to reduce its overall operational greenhouse gas emissions by 42 per cent.
