​Our Department

Our Department’s main responsibility is to formulate and implement policy and legislation on the liberalisation and regulation of the gas markets. Please visit our legislation page for a full list of gas legislation.


Gas Supply

Ireland’s natural gas comes from both indigenous production and imports. The indigenous resources include gas fields at Kinsale and Corrib.

The Corrib gas field commenced production on 30 December 2015. It will greatly enhance our security of supply in that it will provide diversity of supply for the duration of its production.

Since the start of 2016, Corrib production accounts for approximately 36% of gas demand. It is expected that this will rise to approximately 60% in 2016/17 and approximately 50% in 2017/18. Thereafter production is expected to decline.

The balance of our natural gas requirement is imported from Britain. The price of gas on the Irish market is determined by the marginal cost of this imported gas. Gas is imported from Britain via a system of sub-sea pipelines from Scotland (interconnectors).

As a result, the price we pay for our gas as a commodity is set by the price of natural gas at the UK gas trading hub plus the cost of transporting it to Ireland via the subsea pipelines from Scotland. 


Gas Network

The gas network is a system of transmission and distribution pipelines through which natural gas is supplied to Irish homes and business.

The transmission network consists of pipelines that operate at high pressures. The transmission network is used to move large volumes of natural gas. The gas network forms a ring extending through the cities of Dublin, Cork, Limerick and Galway. In addition, there are spurs to, among other places, Louth, Cavan and Waterford.

The distribution network consists of smaller distribution pipes which typically supply urban areas. Each distribution system is connected to the higher pressure transmission system at a pressure reduction station.

Very large users of natural gas, such as power stations, are supplied directly from the transmission network. Other users (including residential users) receive natural gas via the distribution network.

The Commission for Reulation Utilities (CRU) is responsible for the economic regulation of the Irish gas network.

Gas Networks Ireland (GNI) own, operate, build and maintain the natural gas network in Ireland. GNI connects all customers to the network regardless of which natural gas supply company the customer chooses.


Gas Competition

Ireland's retail gas market opened to competition on 1 July 2007. This means that suppliers can enter the market and compete for business. Since 2007, competition has continued to develop in all aspects of the market. As a result, all sectors of the gas supply market have been deregulated since 1 July 2014.

The Commission for Regulation of Utilities (CRU) is Ireland's independent energy regulator. The aim of CRU's economic role is to protect the interests of energy customers, maintain security of supply. More information on switching supplier is available on the CRU website.

Carbon monoxide information

Carbon Monoxide (also known as CO) is a colourless, odourless, tasteless, poisonous gas. It is produced when fuels such as coal, wood, petrol, oil, LPG (propane and butane) or natural gas do not have enough oxygen to burn completely. Dangerous levels of CO can accumulate when the fuel is not burning properly as a result of poor ventilation, blocked chimney or flue, or damaged appliances.

Information on Carbon Monoxide and gas safety in the home can be found at the carbon monoxide website
