Ireland

Fraunhofer ISE, in collaboration with Irishi energy company ESB, developed a methodology showing that Ireland is a competitive location for renewable power-to-X and green hydrogen production with costs comparable to Morocco, South Africa, and Brazil, supported by strong wind resources, policy backing, and infrastructure potential.

The CEO of Irish PV association Solar Ireland, Ronan Power, told pv magazine that despite a healthy project pipeline and investor appetite, ground-mounted PV projects are not being delivered as fast as they could be. A national clearing house to provide more defined communication at the early stages would help developers deliver faster.

Perigus Energy has named Meta, Amazon, Johnson & Johnson, Flogas, and SWW Wunsiedel as corporate power offtakers, confirming that 204.85 MW – just more than 35% of its 578 MW operational portfolio – is contracted through corporate power purchase agreements (PPAs).

Grid-scale solar PV electricity generation surpassed 1 GW in mid-April, which marked a new record in Ireland according to the country’s high-voltage transmission system operator Eirgrid. Around 500,000 customers’ power needs can be met with 1 GW, Eirgrid estimates.

Ireland recorded more than 10,000 applications for solar PV as part of its home energy upgrade program from January to March 2026, an increase of 65% on the same period for last year.

Due for completion in 2028, the DUB20 data center campus in County Wicklow will feature battery energy storage and solar PV installations capable of generating 6,000 MWh annually. It will be Ireland’s first Green Energy Park, delivered as part of its large energy users action plan (LEAP).

Solar Ireland told the Irish government that the Private Wires Bill’s proposed definition of private wires could bring rooftop solar installations within a full electricity licensing requirement, which would place significant additional demand on the energy regulator and slow down installations.

Researchers reviewed 110 studies on cold thermal energy storage in liquid-air energy storage, finding that cold storage performance has a far greater impact on system efficiency than previously assumed. While phase change materials offer high theoretical efficiency gains, simpler packed-bed sensible heat systems are currently the most mature and cost-effective option, with further experimental validation needed to bridge the gap to large-scale deployment.

Ireland reached 2,345 MW of installed solar capacity by December 2025, more than tripling installed capacity since 2023, according to Solar Ireland data. The country’s development pipeline has currently reached 1.7 GW.

The Irish heating specialist has launched a high-temperature heat pump delivering up to 110 C hot water and heating capacities of 100 kW to 370 kW for industrial and district heating applications. The system achieves a coefficient of temperature of up to 4.63.
