Ireland — Energy Infrastructure

OverWatts maps 174 energy assets in Ireland across 7 layers — the 47th-largest mapped base of 157 countries. They include 129 power plants, 18 pipelines and 14 oil & gas fields. Operating generation capacity is 7.4 GW, led by gas at 64%.

The companies named on the most assets are Gas Networks Ireland (17), Electricity Supply Board (11) and Europa Oil & Gas (10), counting both ownership and operatorship. Half of Ireland's mapped assets in service predate 2011 (median commissioning year of the 44 with a known date), 16 came online in the past decade and the oldest still listed is Limerick Cement Plant, dating from 1938. 40+ projects are under construction or proposed, led by Rian Offshore Array wind farm (2.5 GW).
