Dáil debates Bill to attach climate conditions to electricity grid connections

The Dáil has debated legislation proposing to empower the Commission for Regulation of Utilities (CRU) to attach climate requirements to electricity grid connection agreements.

Moving the Electricity Regulation (Climate Action and Connection to Distribution and Transmission Systems) Bill 2025 at Second Stage, Labour Deputy Ciarán Ahern stated the Bill would amend the Electricity Regulation Act 1999. The amendment would give the CRU explicit statutory authority to make climate-related requirements a condition of connection to, or use of, the national transmission and distribution systems.

Under the proposed measures, the regulator could require applicants to take specified actions to avoid, prevent, reduce, offset, or abate greenhouse gas emissions, or otherwise advance the national climate objective.

The debate highlighted regulatory challenges surrounding connections for large energy users, particularly data centres. Deputy Ahern noted that while the CRU's connection policy requires data centres to provide generation capacity matching their maximum import capacity and source 80% of that capacity from renewables within six years, the regulator had previously indicated that existing legislation did not provide explicit power to mandate specific emission reductions or renewable generation requirements.

The Bill seeks to address that statutory gap under the Climate Action and Low Carbon Development Act 2015, enabling the regulator to set direct emissions abatement conditions before approving connections to the national network.
