Stop using 20th century technology in the 21st century

Brief

Decarbonize! (presentation, 2026-06-08) opposes Kilshane Energy’s proposed 680 MW Dublin peaker and argues for replacing peaking gas with grid‑scale batteries. The video compares costs, flexibility, and emissions, cites California and Australia battery growth and Aliso Canyon lessons, highlights stranded‑asset risk, and notes planners refused permission for the plant.

Why it matters

Kilshane Energy lodged plans for a 680 MW gas peaker power plant in Dublin (Pleanála case 323897); planners later refused permission, and the proposal would have locked Ireland into decades of fossil‑fuel peaking capacity and fuel dependence.

Key details

  • Grid‑scale batteries are presented as a cleaner, cheaper, and more flexible alternative for peak balancing: evidence cited includes rapid growth of California’s battery fleet through 2025, Australia’s big batteries overtaking peaking gas on the main grid, and the Aliso Canyon (2015) disaster as a cautionary example.
Source evidence

Kilshane Energy proposes building a 680 MW gas peaker power plant in Dublin, Ireland. However, grid-scale batteries offer a cleaner, cheaper, and more flexible alternative for balancing the grid during peak demand. Building the gas plant would lock Ireland into decades of pollution and fuel dependence, while batteries could enable a modern, renewable-powered grid.
