In Short : Ireland’s Single Electricity Market (which includes both the Republic and Northern Ireland) reduced about 88.7 GWh of solar power in H1 2025, a seven-fold increase since 2022, underscoring the increasing difficulties in integrating solar at scale.
Encouraging Grid Limitations During Fast Solar Development
The main factors, according to experts, are a rise in solar capacity and inadequate grid infrastructure. In stark contrast to Great Britain, where solar curtailment is still essentially nonexistent, the system is having difficulty handling the enormous quantity of excess solar power that it cannot handle, according to a senior analyst at Montel Energy.
Impact and Significance of Clean Energy
Better grid flexibility alternatives, including battery storage, grid enhancements, or improved dispatch mechanisms, are desperately needed, as this graph shows. Without these, nations run the danger of stalling their transition to renewable energy and diminishing the full return on their solar investments.
About the Insight
These findings are based on a Montel-Energy analysis that was published by pv-magazine. The analysis tracked outflows of renewable energy and found patterns of curtailment in both Great Britain and Ireland, providing a data-supported caution for energy planners around the world.
