About

synthesis · audited 2026-08 as of 2026-07

Ireland's state-owned electricity company, which owns generation and the national networks, giving it a role in Irish energy policy well beyond its own portfolio. Its offshore build-out runs through partnerships: operating stakes in Scottish and English waters, a large Scottish project under construction, and earlier-stage development in Irish waters.
