EirGrid Winter Outlook 2025/26

The Loss of Load Expectation (LOLE) in Ireland for the five months of the winter period being studied is 1.1 hours. The LOLE has reduced from 3.6 hours last winter and 21 hours the previous winter. It is inside the 3 hours per year standard. This means the system will operate within the level of risk that is set by the Department of Climate, Energy and the Environment. The system may enter the Alert State at times, most likely at periods of low wind and low interconnector imports.
