200. To ask the Minister for Environment, Community and Local Government the sources of energy used to fuel the production of electricity at the State’s electricity power stations, in tabular form; and if he will make a statement on the matter. [35115/25]

I propose to take Questions Nos. 200 and 201 together.

According to figures from SEAI's interim 2024 national energy balance report, 86% of electricity consumed in Ireland was produced indigenously in 2024 with imports accounting for 100% of its oil, 79.5% of its gas, and 14.0% of its electricity through interconnectors. In 2024, the majority of electricity generation was from natural gas at 42%, closely followed by renewables at 39.6%, and electricity imports at 14% making up the majority of the remaining generation.

Ireland's energy related emissions in 2024 were down 1.3% on 2023 and are at their lowest level in over 30 years. Energy-related emissions have fallen each year for the last 3 years and are down 11% on 2021-levels. SEAI estimates that electricity sector emissions in 2024 were down 7.5% on 2023.

The full dataset is publicly available from the Sustainable Energy Authority of Ireland at the following link www.seai.ie/data-and-insights/seai-statistics/key-publications/national-energy-balance. The five largest sources of electricity are provided in tabular form below:

Source 2024 %
Gas 42.1%
Wind 31.7%
Interconnection net imports 14.0%
Solar 3.0%
Hydro 2.2%
It should be highlighted that as of the 20 June 2025, Ireland successfully phased out coal for power generation. Ireland’s last coal fired generation plant, Moneypoint, will now be running as a generator of last resort on Heavy Fuel Oil (HFO), to be dispatched only on instruction of EirGrid in order to help to ensure security of electricity supply.

In addition, the 2025 All-Island Resource Adequacy Assessment, published by EirGrid in March 2025, contains a detailed overview of registered capacity of dispatchable generation and interconnectors in Ireland in 2025, including name, fuel type, generator type, and MW capacity. This information can be found in Appendix 3 of the assessment, which can be downloaded at www.eirgrid.ie/news/new-eirgrid-analysis-examines-balance-between-electricity-demand-and-supply-ireland-over-10.
