The Commission for the Regulation of Utilities (CRU) has published the Final Determination for Price Review 6 (PR6), allowing €13.8 billion in revenues for ESB Networks and EirGrid from 2026 to 2030. This investment package, an 80% increase from PR5, aims to support the decarbonization of the Irish electricity system and accommodate rising demand. Projects include the North-South interconnector and key upgrades in Dublin. User tariffs are projected to rise by 15% to 28% during this period due to increased infrastructure costs.

On December 16, 2025, the CRU in Ireland announced the Final Determination for Price Review 6, approving €13.8 billion for ESB Networks and EirGrid from 2026 to 2030, which can rise to €18.9 billion with additional funding needs. This investment targets decarbonization and infrastructure upgrades amid increasing demand, driven by factors such as data centers.
