Ireland’s electricity grid is beginning its most consequential transformation, and the scale of investment is a signal every business energy leader should note. EirGrid has launched its Group Strategy 2026, outlining an €18.9 billion programme of investment in the national transmission network between 2026 and 2030. Approved through the CRU’s Price Review 6, it will deliver the most extensive clean energy programme ever undertaken in Ireland, enabling 9GW of onshore wind and 5GW of offshore wind as the country targets 80% renewable electricity by 2030.

For business energy leaders, this strategy defines the commercial context for the next five years. Three dimensions stand out: the scale of capital across 500 projects including 29 priority transmission upgrades; EirGrid’s workforce growing from 1,500 to over 2,000; and the structural unlock this investment provides for renewable connection, storage, and corporate clean energy procurement across Ireland.

The urgency is grounded in a measurable problem. Approximately 13% of wind energy was dispatched down in 2025, wasted because the grid could not carry it. EirGrid CEO Cathal Marley has placed this at the centre of the strategy. Ireland reached 8GW of renewable electricity connected to the grid in March 2026, making the gap between generation and transmission capacity the defining challenge of this decade.

The offshore renewable energy pipeline adds strategic depth. Five Phase One offshore wind projects off Ireland’s east coast have submitted planning applications with combined capacity of 3.8GW, more than 60% of Ireland’s current peak electricity demand. Price Review 6 is designed to accommodate up to 5GW of offshore wind in the early 2030s. Minister Darragh O’Brien noted that Ireland’s offshore resource is attracting significant international investment interest.

The 500 capital projects include 29 priority transmission upgrades, 27 priority substations, 181 kilometres of new overhead line, and 319 kilometres of underground cable. For energy service companies, project developers, and technology providers, this is a sustained and predictable pipeline. The 189MW of wind and solar connected in the first two months of 2026 confirms delivery is ahead of historical norms.

Three priorities stand out for C-suite leaders. First, map the 29 priority projects against planned renewable and industrial sites to identify early connection opportunities. Second, engage with EirGrid on grid services, where the energy transition is creating revenue streams from flexibility, storage, and demand response. Third, develop offshore wind supply chain propositions now to secure early positions in a sector that will define Irish energy for a generation.

Ireland is building a grid worthy of its renewable ambitions. The €18.9 billion commitment is a regulatory decision, not a projection. Business energy leaders who align strategies with EirGrid’s Group Strategy 2026 will be building on the most solid investment foundation in the European energy transition.
