Poolbeg

Poolbeg station actually consists of two separate power stations:

County: Dublin
Fuel type: Oil; Natural Gas
Capacity: 510MW
Status: Inactive
Commissioned: 1971
Second tower added: 1978
Decommissioned: 2010

Current name: Poolbeg CCGT station
County: Dublin
Fuel type: Gas
Capacity: 463MW
Status: Active
Commissioned: 1994; 1998

 
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. The first two 120MW sets were originally oil-fired – the first set were commissioned in August 1971 and the second set were commissioned in December 1971. A new 270MW set was added in November 1978. Boilers 2 and 3 were converted to gas incrementally, with both fully commissioned in May 1984. The conversion of boiler 1 to gas was completed by July 1984, and the three sets were fully synchronised in March 1985, at a combined capacity of 510MW.

​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.
