Tynagh Energy uses the latest high efficiency technology known as combined cycle gas turbine (CCGT). This involves a highly efficient process whereby electricity is generated by heating natural gas and recycling the resulting steam. This dual process ensures the maximum energy is extracted from every unit of gas.
The Tynagh Power Plant is built under a turnkey contract with a consortium of General Electric Company / General Electric International Inc. and Gama Power Systems Inc.
The gas turbine is a GE 9FA design. F-class gas turbines were developed in the late 1980s and are considered commercially proven with a track record of high availability and reliability. The steam turbine is a GE A15 ‘HEAT’ (high efficiency advanced technology) model, with a GE 9A5 electrical generator.
The designs of both the A15 steam turbine and the 9A5 electrical generator are developments from previous GE models that are fully proven technology. These are logical evolutions from previous models and incorporate GE’s comprehensive design process and field testing facilities which are without doubt world class.
