Ireland in detail

What the national rules say, with the legal texts.

Ireland's Commission for Regulation of Utilities, the CRU, published a decision on 12 December 2025 covering new data centres applying to connect to the electricity grid. According to the CRU, data centres seeking a new connection will be required to provide on-site or near-site dispatchable generation or storage matched to their requested import demand, and to match at least 80% of their annual electricity demand with additional renewable-electricity projects. The decision paper sets how these duties scale with the size of the requested connection.
