Ireland’s energy storage capacity could grow almost eightfold by 2035, according to a new report from Energy Storage Ireland.
The group’s 2025 Pipeline Survey identified 155 projects totalling nearly 10GW of battery capacity, enough to power every home in Ireland twice over on a windless, overcast day.
Head of Energy Storage Ireland Bobby Smith said: “Energy storage solutions can transform our electricity system for the better.”
“The price of batteries has come down by 90% in the past decade, making them a cost-effective way of providing a constant supply of otherwise intermittent renewable energy.”
Launched at the organisation’s annual conference in Croke Park, the report highlights the sector’s potential to reduce fossil fuel reliance and lower consumer bills by storing surplus renewable generation.
In 2024, 14% of all wind energy in Ireland was curtailed due to a lack of storage.
Smith said: “We’ve seen the positive impact of government support schemes in driving the delivery of wind and solar power. We need to see similar schemes put in place for energy storage.”
He cited the UK’s cap and floor scheme as a model and called for policy certainty to unlock the full potential of Ireland’s storage pipeline.
Additional recommendations include simplifying grid connection policy for co-located projects and strengthening the transmission network to enable large-scale storage deployment.
Speakers at the event included Kevin O’Donovan of Statkraft Ireland, Lisa Foley of Cornwall Insight, and MEP Seán Kelly, who delivered the keynote address.
