Windfarm powers up
Wednesday, 2nd October, 2019
The $450 million Silverton Windfarm is providing energy to Broken Hill following the completion of construction and commissioning of the 58 turbines, AGL Project Director Adam Mackett said.
It is powering the Silver City through the connection into TransGrid’s existing 220kV substation in Broken Hill, which feeds the Essential Energy distribution network and some large mines.
“The Silverton Wind Farm is expected to generate about 780,000 megawatt hours of renewable energy, which is enough to power about 137,000 average Australian homes,” Mr Mackett said.
“This renewable energy is utilised by the closest load sources (Broken Hill energy users) and the remaining will flow through the grid to the next closest load sources.”
Mr Mackett said the night output of the windfarm is almost at an end.
“Australian Energy Market Operator (AEMO) commissioning of the wind farm at maximum output of 200 megawatts during the night is also complete.”
At the peak of construction up to 150 people were employed, of which about 40 percent were from the local area.
Local contractors and suppliers included Mawsons Concrete and Quarries, Silverton Civil, Solcon, Vertex Power & Process and Lawrence Engineering.
Construction involved 58 wind turbines, 65 kilometres (km) of site access roads, more than 26,000 cubic metres of concrete, mainly for the turbine foundations, 32 km of underground collector cable, and 23 km of overhead electrical lines.
“Once fully operating there will be 10 full time employees responsible for regular maintenance of the turbines,” Mr Mackett said.
“GE is responsible for completing the commissioning of the wind farm and the ongoing operation and maintenance, and AGL is the asset manager on behalf of the owner, the Powering Australian Renewables Fund.”
