Datasets of hydro energy generators connected to the electricity network are downloadable as GIS shapefiles. Two spatial reference systems are applied to the downloadable shapefiles: Irish Transverse Mercator (ITM) and WGS 84 (EPSG:3857).

Connected generators are those with an electrical connection to the electricity network or “grid”. Each connection is quantified by a Maximum Export Capacity (MEC), expressed in megawatts (MW). Hydro generators built over multiple phases appear in these datasets as individual generators, each with a total MEC value. Such generators are larger, TSO-connected, and built in early decades of the State at: Ardnacrusha, Cliff, Cathleen’s Fall, Inniscarra, and Pollaphuca.

The Sustainable Energy Authority of Ireland (SEAI) offers the same data in its Hydro Mapping System, a digital map of Ireland's hydro energy connections and resources (http://gis.seai.ie/hydro).

Ireland’s Distributed System Operator (DSO) and Transmission System Operator (TSO), ESB Networks and EirGrid respectively, provided the raw data on hydro energy connections. They publish their datasets, for information purposes, at:

DSO Connected-Energised Non-Wind Generators (ESB Networks)

TSO Connected Renewable Generators (EirGrid Group)
