In July 2025, alongside geophysical work, EirGrid began a broader Phase 1 marine and coastal survey programme for the Tonn Nua (Maritime Area A) grid connection, including environmental and metocean investigations and non-intrusive intertidal landfall studies. The programme also involved deploying two MetOcean buoys to collect long‑term data on waves, water quality, wind and sunlight to inform offshore planning and environmental assessment for the transmission infrastructure.
