Clough, as a project contractor to GE Vernova, delivered the engineering, procurement, and construction scope for Tallawarra Stage B, Australia's first net zero emissions hydrogen and gas capable power station in Yallah, New South Wales.

Tallawarra Stage B is a 300+ MW expansion of the existing Tallawarra A power station, involving the construction of a 420MW Open Cycle Gas Turbine Power Plant. Works include the construction of a high voltage switchyard, an unloading station, a distillate tank, connecting gas pipelines, gas receiving and conditioning stations, transformers, switchgear, a control room and an administration building.

At the peak of construction, the project is expected to create hundreds of jobs and inject $300 million to the local economy. Once commissioned, the plant will be ready to start generating electricity for 150,000 homes with only 30 minutes’ notice. The project will address the need for fast-start flexible capacity, to complement renewables coming into the system.
