Ireland curtails 13.2% of wind power in first half of 2026, wasting electricity for 660,000 homes
Ireland was forced to curtail 13.2% of its wind generation in the first half of 2026 because the grid could not carry the output, an amount equivalent to the electricity used by 660,000 homes. Over the same period, wind power integration reached 86.8%. Wind Energy Ireland said the existing network was unable to deliver all wind power to consumers, leaving 15% of the cheapest electricity unused. Grid operator EirGrid said it is upgrading the system with the aim of lifting the share of renewable electricity it can accommodate to 95%.
