Our Generation Portfolio

Aghada

Feb 23, 2022, 16:18 PM
Title : Aghada
Location : Co. Cork
Select a choice : Thermal
Latitude : 51.8350360
Longitude : -8.2280290

Fuel: Natural Gas and Distillate

Capacity: 963MW

Commissioned: 1980 and 2010

Technology:

1 x 270MW Alstrom gas-fired conventional steam turbine (1980)

3 x 90MW Alstrom Frame 9B, dual fuel open cycle gas turbines (1980s)

1 x 435 MW Alstrom single shaft combined cycle gas turbine (2010)


Aghada was built close to the entrance of Cork Harbour in order to use gas discovered in the nearby Kinsale Gas Field. The station started operating in 1980 and has grown over the years to feature three different types of technology (see above).

Taking 30 months to build, the latest combined cycle gas turbine plant is one of the most efficient and cleanest plants in Europe, capable of generating enough electricity to supply approximately 8% of power demand in the Single Electricity Market (Island of Ireland).

With its combination of three types of generating technologies (open cycle gas turbines, steam turbine and combined cycle gas turbine) Aghada is extremely flexible and important to our generation portfolio.

Hydrogen

We believe hydrogen produced from renewable electricity will play a critical role in the decarbonisation of many sectors.
