Poolbeg is situated adjacent to the now-decommissioned Pigeon House generating station, where electricity was first generated in 1903 also with the distinction of being the first in the world to generate three phase power.
The Pigeon House was previously a military barracks and the officers accommodation building still exists.
It was used for power generation until it was decommissioned in 1976, and the Poolbeg plant is still known locally as the Pigeon House.

The modern Poolbeg station was constructed in two separate phases, beginning in the 1960s.
 The ESB decided to construct the station in 1965 and the initial development was completed in 1971 with the construction of Units 1 and 2 at a cost of 20 million Irish pounds.
The original Pigeon House generators remained on standby duty until 1976.
Unit 3 was completed in 1978 at a cost of 40 million pounds.

The combined cycle station was constructed in the 1990s.
CG14 was commissioned in 1994, CG15 in 1998 and ST16 in 2001.
