Cushaling Power is a 116 MW peaking plant located adjacent to the Edenderry Power Plant, just north of Clonbullogue, Co. Offaly. It consists of two open cycle gas turbine (OCGT) units that are fuelled by distillate oil. These units act primarily as reserve capacity on the grid, and only operate for a few hundred hours per annum.
The Cushaling power units can start up and reach full power output in less than ten minutes. They can also provide the electricity system with a range of ancillary services that are necessary to ensure the stable operation of the Grid.
Following commissioning and testing during the summer of 2010, the Cushaling units entered commercial operation in September 2010 and provided a significant level of system support during the harsh winter of 2010/11. The units have continued to support the safe and stable operation of the Irish power grid ever since.
