Poolbeg Generating Station, colloquially known as The Poolbeg Stacks is a power station owned and operated by the Electricity Supply Board of Ireland (ESB). There are two stations on the site, the older thermal station containing units 1, 2, and 3 and the combined cycle gas station containing units CG14, CG15 and ST16, which is located toward the eastern end of the site. The six units have a total installed capacity of 1020 MW.
The plant is located on the Poolbeg peninsula in Ringsend, Dublin, on the south bank of Dublin Port. Its two chimneys, at just over 207 metres, are visible over much of Dublin, particularly Sandymount Strand, making them well-known landmarks and some of the tallest structures in Ireland.
