A gas turbine stripped down to nothing but its casing brings to mind a scene from an automaker’s assembly line: an empty chassis that’s full of potential. Next year, a GE team will seek to realize such potential at the 435-megawatt Tallawarra A power station, 60 miles south of Sydney on the New South Wales coast. The goal is to transform an existing GE turbine there into one that will be more efficient and require less natural gas to generate electricity.
Long reliant on coal to make electricity, Australia is increasingly looking to renewable sources like wind and solar. But generating reliable, renewable power demands shoring up the grid when the breeze won’t blow and the sun won’t shine — and natural gas power is an efficient dispatchable power that can backstop these sources, and help immediately reduce emissions from coal-fired power.
