Fuel: Natural gas with distillate as an emergency back-up
Capacity: 463 MW
Commissioned: 1971, 1984 and 2000
Technology: Combined cycle gas Turbine
The City of Dublin Electricity Works founded Pigeon House Power Station in 1903 and the site supplied most of Dublin’s electricity until the 1950s.
We took over the site in 1971 and the station has been through several technology changes since then.
More recently, in 2000, we upgraded Poolbeg to use combined gas cycle technology (CCGT). At the time, this brought the CCGT unit thermal efficiency to 52% and overall output to 480 MW. The CCGT technology includes: two Siemens V94.2 gas turbines, two Siemens/Austrian Energy Heat Recover Steam Generators (boilers) and one Siemens steam turbine. Siemens electrical generators are fitted to each of the two gas turbines and steam turbine.
Finally, on 31 March 2010, we retired Poolbeg Units 1, 2 and 3, leaving the station’s output at 480MW MW from the CCGT unit.
