Ireland’s grid bottleneck slows wind power expansion, industry warns
Ireland’s electricity grid is now the main obstacle to adding more renewable generation, with over 3,000MW of permitted onshore wind waiting for connections. Dave Linehan of Wind Energy Ireland said dispatch-down reached 15% in the first half of 2026, which raises investment concerns and adds consumer costs. He called for short-term fixes while larger grid projects are built, noting some projects have connection dates in the late 2030s.
Wind Energy Ireland’s policy and research director, Dave Linehan, said the organisation’s Onshore Wind Action Plan followed roughly half a year of member consultations. Those talks identified the electricity network as the dominant barrier. More than 3,000MW of onshore wind with permits is awaiting connection.
In the first half of 2026, curtailment of available renewable output reached 15%, according to Linehan. He also noted some projects now seeking approval have connection dates in the late 2030s. Long-duration storage and hybrid links were cited as near-term options.
Households and businesses may face higher electricity costs if renewable output is curtailed and projects are delayed, while investors could become more cautious about Irish wind developments. Communities hoping for local energy investment may see benefits postponed. If grid upgrades and short-term measures proceed, consumers could eventually gain from more domestic renewable power and improved energy security; otherwise, the gap between climate goals and delivery may widen.
