- Category: Thermal
- Energy type: Oil
- Project type: Asset
Great Island power station is situated on the shores of Waterford Harbour at the confluence of the Rivers Suir and Barrow at Great Island, Co. Wexford.
The station comprises two 60MW and one 120MW oil-fired turbines and commenced commercial operations in 1967. Its principal function is to help maintain security of electricity supply in Irelands all-island Single Electricity Market (SEM) by being available to operate on quick responses to peak in national energy demand.
SSE is currently constructing a 460MW CCGT (combined cycle gas turbine) on the shores of Waterford Harbour at Great Island, Co. Wexford, which is expected to be commissioned in 2014. When completed, it will replace the existing 240MW fuel oil unit at the existing site significantly reducing carbon emissions in Ireland.
