EirGrid, the operator and developer of Ireland's electricity grid, has welcomed the Commission for Regulation of Utilities' final Price Review 6 (PR6) Determination, which approves investment to strengthen and expand the network.

The company said the PR6 funding will allow it to deliver an unprecedented volume of new infrastructure in the coming years, supporting Government policy priorities in areas including housing, climate and industry.

The CRU's final decision follows EirGrid's initial PR6 submission in 2024. That submission arose from collaborative work with ESB Networks to identify the onshore system investments required out to 2030, alongside ongoing engagement with the regulator on the need to progress both onshore and offshore grid development and manage an increasingly complex power system.

EirGrid balances electricity supply and demand from the National Control Centre while planning for Ireland's long‑term needs. Its costs are approved in five‑year cycles through the CRU's Price Review process.

For the 2026–2030 PR6 period, EirGrid set out objectives focused on: significant investment in technology and people to underpin secure and reliable system operation; a major onshore capital programme including 29 large projects to enhance security of supply, unlock capacity and enable renewables; assuming ownership and responsibility for offshore transmission assets; and preparing grid and market operations to integrate the Celtic Interconnector between Ireland and France.

Speaking about the determination, Michael Behan, Chief Financial Officer at EirGrid, said: "Innovating and investing is key to delivering a stronger, more resilient electricity grid and the PR6 determination signals the support of EirGrid's ambitious plans out to 2030, in line with robust accountability and reporting to the CRU."

Also welcoming the determination, Siobhán O'Shea, EirGrid Chief Infrastructure Officer Onshore (Interim), said: "It is critical we have a clean, secure power system that supports increasing societal and economic growth.

"At EirGrid we're committed to developing a grid that evolves to meet the needs of communities and businesses for decades to come, and the PR6 determination is another step forward in ensuring we can deliver."

EirGrid added that its PR6 plan builds on recent progress, including major reinforcements to the transmission system and the advancement of critical projects, supported by investment under PR5.
