Siemens will manufacture 32 of its 3.2MW turbines for the Hornsdale project in South Australia, will service the turbines, and will set up a skills centre to train engineers. The medium-wind turbine will have a 113-metre diameter rotor.
Hornsdale is located near the town of Jamestown, 200 kilometres north of Adelaide.
The project's power will be sold to the Australian Capital Territory (ACT) government at a fixed price of A$0.092/kWh ($0.067/kWh) for 20 years.
Neoen won the license to develop Hornsdale from the ACT government in February. The project has potential to increase to 270MW, following the initial 100MW phase.
According to Siemens, construction at the project will begin immediately. The manufacturer also signed an engineering, procurement and construction deal with Neoen, alongside a long-term servicing contract.
As part of the project, a "renewable energy skills centre of excellence" will be set up to train engineers to maintain wind projects.
The Australian government recently approved a cut to the renewbale energy target subsidy - an improvement on the expected full removal of the subsidy. The central government is now looking to supply 33TWh of renewable energy by 2020, down from the previous target of 41TWh.
Siemens said the Hornsdale project will help the ACT government, which is hoping to achieve 90% renewable energy by 2020.
