AIMG Visit to Aghada Power Station

The IChemE All Ireland Member Group (AIMG) in conjunction with Engineers Ireland (EI) completed a site visit to Aghada Power Station in Whitegate, Co. Cork on 21st May 2014. 



On a warm sunny day in the Lower Cork Harbour, 18 engineers visited the recently built 435 MW gas fired combined cycle gas turbine (CCGT) power plant at ESB Aghada Generating Station.  The morning began with an informal introduction over tea and coffee followed by a presentation from Adrian Dennehy (ESB International) on the Station and in particular on the CCGT plant.  The group then spilt into two smaller groups and were escorted around the site by Eliz Stack (Station Chemist), Kevin O’Donoghue (Operations Manager) and Sean Walsh (Maintenance Manager).  A very informative and worthwhile visit was had by all and everyone was highly impressed by the scale and complexity of the plant as well as the operations team on site.


About Aghada Generating Station:

The plant comprises two stations; the first 528 MW was commissioned in 1980 with the second 435MW added in 2010. Unit 1 is a gas-fired conventional steam turbine plant of 258 MW capacity. CT11, CT12 and CT14 are three open cycle gas turbines which are gas or distillate fired, each with a capacity of approximately 90MW. In April 2010, the capacity of the station was increased from 528 MW to 963 MW when a new state-of-the-art 435 MW Combined Cycle Gas Turbine entered commercial operation. The gas-fired plant is one of the most efficient and cleanest plants in Europe and generates enough electricity to supply approximately 8% of power demand in the Single Electricity Market.  Aghada Generating Station is also the only power station which serves all three market segments of baseload, mid-merit and peaking demand.   The new plant, which was constructed over a 30 month period at a cost of €360m, entered commercial operations in 2010.
