CCGT Power Plants in Ireland
Aghada
Location: County Cork
Operator: Electricity Supply Board
Configuration: 435-MW, single-shaft CCGT with GT26B 2.2 gas turbine
Fuel: natural gas
Operation: 2010
HRSG supplier: Alstom
T/G supplier: Alstom
EPC: Alstom
Quick facts: The necessary approvals for this CCGT plant near Whitegate were received in Apr 2007. Alstom mobilized on-site in Jul 2007 and the plant was officially opened on 31 May 2010 by Minister for Foreign Affairs Micheál Martin. The new plant cost €360mn. The dual-fuel GT26 is an upgraded version of the Synergen plant in operation at Ringsend. A key plant component is a 440m outfall pipe for discharging cooling water into Cork harbour. This HDPE pipe was extruded in one piece, towed to site from Norway, and laid below the seabed by the engineering contractors Van Oord. The peak construction work force was about 550. Natural gas is supplied via a new 12km pipe built by Bord Gáis Eireann.

Great Island CC
Location: County Wexford
Operator: SSE Ireland
Configuration: 464-MW, single-shaft CCGT with M701F gas turbine
Fuel: natural gas, oil
Operation: 2015
HRSG supplier: Nooter
T/G supplier: MHI, Melco
EPC: Cobra, Dragados, Initec
Quick facts: The Great Island CCGT has a 143ac brownfield site adjacent to three conventional heav-oil units (240 MW in total). The new block was orginally acquired for Endesa's cancelled Cubillos del Sil project in Spain. The unit was synchronized in Sep 2014 and went commercial at 555am on 17 Apr 2015. The old sets were immediately retired. A new 220kV cable connects to EirGrid’s 220kV GIS compound and Bord Gáis Networks built a gas connection to the plant. The €330mn project had a peak workforce of about 1,200 and almost 3mn manhours were expended on the job.

North Wall
Location: County Dublin
Operator: Electricity Supply Board
Configuration: 155-MW 1+3 CCGT with 9001ETG gas turbine, 1 X 104-MW 9001ETG gas turbine
Fuel: natural gas, oil
Operation: 1982
HRSG supplier: CMI
T/G supplier: EGT, Alsthom, ABB
EPC: ESB
Quick facts: The first units at North Wall went online in 1947 making this the first thermal power station developed by ESB. The site is in Dublin Port on the north side of the River Liffey. In 1982, the station was converted to a combined cycle plant following a significant investment by ESB to purchase two new gas turbines and a waste heat recovery boiler. Gas is piped into the station by Bord Gáis and distillate is delivered by tankers where it is stored in four 4,000m3 tanks. Generated power is fed to the grid at 220kV and directly into the Dublin City network at 38kV.
