EirGrid Group, which operates, develops and enhances Ireland's electricity grid, has published its 2025 Annual Report (29 June 2026), covering the period from 1 October 2024 to 30 September 2025 and detailing financial and operational performance.

The company said it is pursuing a significant multi-year capital investment programme and plans to continue strengthening its finances to deliver critical electricity infrastructure that supports Ireland’s transition to a low‑carbon society as well as broader social and economic growth.

Reported profit before tax under International Financial Reporting Standards rose to €429.1m from €9.8m the previous year. EirGrid said this reflected regulatory timing differences — including the recovery in 2024–25 of revenues for costs recognised in prior years and over‑recoveries for the current year to be returned in future tariffs — alongside the release of a €151m grant.

EirGrid emphasised that these effects do not indicate underlying profit growth. Total underlying profit was €23.2m, compared with €25.6m the year before.

In October 2025, the company paid an annual dividend of €4.0m in respect of the 2023–24 financial year and also made a special dividend payment of €50.0m in 2024–25. It is proposing a dividend of €4.0m to the Government this year.

EirGrid said it is progressing the most ambitious programme yet on Ireland’s transmission system, supporting Government policy on housing, climate and industry. It participated in the new Government‑led Accelerating Infrastructure Taskforce. Network spend on the transmission system totalled €37.8m during the financial year.

Costs are set and overseen in five‑year cycles through the Commission for Regulation of Utilities (CRU) Price Review process. EirGrid submitted its plan for PR6 (2026–2030) aligned with Government and CRU objectives. An investment package of up to €18.9bn has subsequently been made available to EirGrid and ESB Networks over the next five years.

Key highlights for the year to 30 September 2025 included:

- 394 MW of new renewable projects connected to the transmission system (180 MW solar, 151 MW wind, 63 MW storage)

- 28 projects energised and 40 project agreements reached

- A new electricity demand peak for Ireland of 6,024 MW on 8 January 2025

- A €2bn Government equity commitment for offshore transmission infrastructure

- South Coast Marine Surveys commenced for Powering up Offshore South Coast, to bring power from south coast offshore windfarms into the national grid

- Continued construction of the Celtic Interconnector with French TSO RTE, with 84km of submarine cable laid in Irish waters

- A planning application lodged for a Central Dublin Substation under the Powering Up Dublin programme

- 16 planning applications lodged, with 9 granted

Chair of EirGrid Group, Brendan Tuohy, said: "EirGrid's core responsibility is to operate Ireland’s electricity system safely, securely and reliably. This Annual Report shows that, during a period of significant change, EirGrid continued to meet that responsibility while preparing for the scale of delivery now required.

"The coming years will be decisive. As Ireland’s economy and society transition increasingly to electricity for heat, transport, enterprise and other energy needs, future economic and social development will depend critically on a strong, resilient electricity system.

"That means delivering major grid infrastructure at pace, integrating more renewable generation, and keeping security of supply and cost competitiveness central to every decision. EirGrid will build on progress made and work with Government, regulators, industry and communities to deliver the infrastructure Ireland needs."
