Ireland is beginning to reconsider its long-standing opposition to nuclear power as concerns over energy security, high electricity costs, and future demand intensify. Taoiseach Micheál Martin acknowledged that Ireland will effectively be importing electricity generated from French nuclear reactors once the Celtic interconnector with France becomes operational. He stated that, “to all intents and purposes,” Ireland will be supporting energy produced through France’s nuclear capacity. This admission has renewed debate about whether Ireland should continue banning domestic nuclear development while simultaneously relying on imported nuclear-generated electricity.
The discussion emerged after Independent Ireland TD Ken O’Flynn urged the Government to remove the 1999 prohibition on developing nuclear power plants and reverse restrictions on gas and oil exploration. O’Flynn argued that Ireland’s current position is contradictory because it opposes domestic nuclear development while benefiting from imported nuclear electricity. In response, Martin stressed that Ireland’s immediate priority remains renewable energy, particularly offshore wind, solar, and anaerobic digestion. He highlighted the country’s recent progress in solar energy expansion but also insisted that a “serious examination” of nuclear energy is necessary to evaluate costs, timelines, and long-term feasibility.
The Taoiseach’s comments reflect growing pressure on Ireland’s energy system. Recent Eurostat data showed that Irish electricity prices are now the highest in the European Union, with consumers paying nearly 40 percent more than the EU average. Rising energy costs have been worsened by geopolitical instability, including the conflict involving Iran, which has contributed to volatility in global fuel markets. Against this backdrop, supporters of nuclear energy argue that Ireland should at least consider alternative low-carbon energy sources that could reduce dependence on imported fossil fuels and improve energy security.
Part of the renewed interest comes from advances in nuclear technology, particularly small modular reactors (SMRs). These next-generation reactors are designed to be smaller, cheaper, and faster to construct than traditional nuclear plants. Advocates believe these innovations may reduce some of the historical barriers associated with nuclear projects, including long construction times and extremely high upfront costs. Fianna Fáil TD James O’Connor recently introduced legislation aimed at ending Ireland’s ban on developing nuclear facilities, and the Government has indicated it is willing to examine the proposal.
However, opposition parties strongly criticized the idea. People Before Profit TD Paul Murphy described the nuclear debate as “crazy” and argued that Ireland should instead focus entirely on renewable energy. He raised concerns about nuclear safety and suggested that support for nuclear energy is partly driven by attempts to avoid addressing the large electricity demands of data centres. Murphy called for a state-led expansion of renewable infrastructure, similar to the historic development of the Ardnacrusha hydroelectric project in the 1920s.
Green Party Senator Malcolm Noonan also dismissed the debate as a distraction from more urgent affordability concerns. He argued that discussions about nuclear energy should take place through the Oireachtas Climate Committee, which is already reviewing issues related to nuclear waste from the Sellafield facility in England. Meanwhile, Aontú leader Peadar Tóibín said his party remains open to nuclear power in principle, although he predicted that few politicians would welcome a reactor in their own constituency. Overall, the debate highlights Ireland’s growing struggle to balance affordability, climate goals, energy independence, and public acceptance of new energy technologies.
