Ireland's Solar Power Surges, But Grid Inefficiency Wastes Clean Energy

Ireland's early summer heatwave significantly boosted solar power, with Solar Ireland reporting that solar energy supplied one-third of the nation's energy needs on Monday afternoon. However, the industry group warns that much of this clean, renewable energy is being wasted due to an inefficient national grid and infrastructure that cannot keep pace with record generation levels.

Ronan Power of Solar Ireland stated that the sector is growing rapidly, noting that the State's first utility-scale solar farm was connected only in 2022. Despite this growth, companies sometimes must curtail renewable generation because the system struggles to absorb all available clean energy. Power emphasized the need for system optimization using existing technology and accelerated grid investment to ensure infrastructure and operational measures keep pace with renewable deployment.

In April, wind power was Ireland's largest renewable contributor, accounting for 38% of all electricity generated. Overall, 48% of electricity came from renewable sources in April, with 6% from large grid-scale solar farms. EirGrid reported this as the third consecutive month where renewables met around half of electricity demand, with ongoing investments enabling up to 75% of electricity from variable renewable sources at any one time, aiming for 95%.
