Power networks/Ireland

High-volate power lines in Open Infrastructure Map.

This page describes the electrical power network of Ireland (Q27), including Northern Ireland (Q26). It also provides guidance on how to map the network accurately in OpenStreetMap.

Network statistics

The bellow statistics are automatically generated from Open Infrastructure Map, as such these statistics do not include data from Northern Ireland, as this would fall under the United Kingdom.

Ireland has 315 power plants totalling 13,353 MW and 41,411 km of power lines mapped on OpenStreetMap (from OpenInfraMap, last update 2025-09-13)

Mapping process and community

Mapping success stories

TODO : Success stories are designed to highlight important contributions. Have you significantly improved the cartography of a country (added a new line, a power station, etc.)? Don't be shy, let us know below.

• Example : NAME [DATE YYYY-MM-DD]: My success stories in words.

Encountered problems and places to improve

Use of mapping strategies

TODO : Mapping strategies refer to Power networks/Guidelines#Mapping strategies. They are used for a methodical improvement of the OSM database. Once you have fully applied a strategy in this country, you should add or update your name, the date, the strategy, and a comment below. This way, other users can see whether it is worthwhile to carry out further investigations.

• Example : Search for "Unfinished major power lines" - last time applied by XXX [2025-MM-DD]
