Private wires legislation could slow Ireland’s residential rooftop PV progress
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.
Cold thermal storage crucial to boosting liquid-air energy storage efficiency
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 adds 1 GW of solar in 2025
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.
Trane presents high-temperature water-to-water heat pump
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.
Irish solar rises in 2025 as government plans €18.9 billion of grid upgrades
Provisional data from the Sustainable Energy Authority of Ireland (SEAI) for 2025 showed that monthly utility-scale solar generation increased from an average of 0.73 TWh in 2024 to 0.99 TWh in the first nine months of 2025.
Ireland reaches 1 GW of installed rooftop PV capacity
Ireland surpassed 2.1 GW of installed solar capacity in November 2025, and the country’s solar association, Solar Ireland, has revealed that 1 GW of this is from rooftop installations.
Irish energy industry calls for 500 MW of storage capacity by 2030
Irish grid operator EirGrid has set the proposed minimum procurement for long-duration energy storage (LDES) procurement at 201 MW, well below its initial 2030 goal of 500 MW of storage capacity.
Ireland surpasses 2 GW of installed solar capacity
Ireland’s national solar capacity has risen to 2.1 GW as buildout has accelerated since the first utility-scale project came online in April 2022.
Ireland earmarks €27 million for energy communities
Ireland is investing close to €27 million ($31 million) in community-based energy projects promoting climate action, including small-scale solar installations around the country. A previous phase of the program allocated a total of €24 million to 650 community projects.
Ireland reveals plans for electricity interconnector with Spain
Ireland’s Minister for Climate, Energy and the Environment, Darragh O’Brien, said the project could be co-funded by the EU and finalized in the mid-2030s.
