Kerry Power Plant Receives Final Approval After Legal Challenge

A major power plant project in North Kerry has received final approval following a High Court decision dismissing a challenge brought by an environmental group. The ruling paves the way for the construction of a 600-megawatt power plant and battery storage facility, a project that has faced significant legal hurdles.

Background of the Project

Shannon LNG Limited secured planning permission from An Coimisiún Pleanála (ABP) in March 2025 for the development on a 255-hectare (630-acre) site between Tarbert and Ballylongford on the Shannon estuary. Friends of the Irish Environment (FIE) subsequently launched a judicial review, contesting the decision.

The Legal Challenge

FIE argued that ABP failed to adequately consider statutory carbon budgets and sectoral emissions ceilings outlined in the Government’s Climate Action Plan 2024, as well as obligations under the Climate Action and Low Carbon Development Act 2015. They claimed the environmental impact assessment underestimated greenhouse gas emissions, potentially accounting for one-third of the entire electricity sector’s budgeted emissions for 2030.

High Court Ruling

On Wednesday, April 2, 2026, Judge Richard Humphreys dismissed the proceedings brought by FIE. This decision marks the seventh legal ruling related to the project, highlighting its complex and contested history. The judge acknowledged the logic behind the environmentalist argument to “keep it in the ground” but ultimately sided with the planning board’s decision.

Project Details

The power plant will have a total installed capacity of 600 megawatts, sufficient to power approximately 160,000 homes. The development also includes a 120-megawatt Battery Energy Storage System. The site encompasses a 630-acre area and features three turbine halls, each 30 meters in height, along with ancillary structures and two 35-meter exhaust stacks.

Government and Local Reaction

Government Minister Norma Foley stated the decision could bring significant employment opportunities to the region. Minister of State Michael Healy-Rae also expressed a positive outlook.

Looking Ahead

With the legal challenges resolved, Shannon LNG can now proceed with the construction of the power plant. The project is expected to contribute to Ireland’s energy infrastructure and provide increased flexibility given the growing amount of renewable energy on the grid.
