Discover more about Gas Networks Ireland.

Who we are

Gas Networks Ireland operates and maintains Ireland’s €2.8bn, 14,725km national gas network, which is considered one of the safest and most modern renewables-ready gas networks in the world. 

Over 720,000 homes and businesses trust Ireland’s gas network to provide efficient and reliable energy to meet their heating, cooking, manufacturing and transport needs. 

The gas network is the cornerstone of Ireland’s energy system, securely supplying more than 30% of Ireland’s total energy, including 40% of all heating and almost 50% of the country’s electricity generation. 

By working to replace natural gas with renewable gases, such as biomethane and green hydrogen, and complementing intermittent renewable electricity, Gas Networks Ireland is supporting Ireland’s journey to a cleaner energy future. 

The role of Gas Networks Ireland

Delivering a safe, secure and efficient supply for customers

We ensure that over 720,000 natural gas customers receive a safe, efficient and secure supply of gas, 24 hours a day, 365 days a year.

Transporting gas through our network

We transport gas through our 14,725km renewable-ready pipeline network. As well as maintaining networks in the Republic of Ireland and Northern Ireland, we have pipelines in Scotland, Northern Ireland and the Isle of Man. We do not own the gas; we transport it on behalf of suppliers and shippers.

Investing in new business areas

As guardians of the national gas network we are working to deliver a cleaner energy future for Ireland. We are investing in new technologies such as compressed natural gas (CNG) and bioCNG for transport and renewable gases such as biomethane and green hydrogen

Connecting customers to the network

Through the New Connections Programme, Gas Networks Ireland brings the benefits of gas to new customers in line with the Commission for Regulation of Utilities (CRU) policy. We connect all customers to the network, regardless of their supplier.

Managing our gas emergency service

We manage a 24 hour gas emergency service handling over 14,000 call-outs a year.

Maintaining reliability and resilience

As the natural gas network infrastructure is predominantly underground, it demonstrates great resilience and reliability through severe winter weather conditions.
