TransGrid has finished construction on a new $50 million substation at Macarthur to reinforce electricity supply in the fast developing South West Sydney region.
The new substation provides Sydney’s South West region with enough power to supply 100,000 homes and businesses. The added capacity the new substation brings to the electricity network in the area will help to keep high levels of reliability for customers in the region.
Areva, a leading international supplier of the latest substation technologies, constructed the Macarthur Substation for TransGrid.
Two modern transformers have been installed and arrived on site by a dedicated entry road, built off the Hume Highway.
The project involved extensive civil and landscaping works. A number of utilities which were close to the site such as water and rail, as well as the difficult slope of the site, meant we needed innovative designs to built this world class substation.
The community was heavily involved in the project. We also did a comprehensive environmental investigation on effects on local flora and fauna as well the location of the Mount Annan Botanic Garden.
A range of innovative techniques were used such as the use of a very compact layout for the substation, the careful selection of colours for higher steel structures and the transformer sound walls to reduce impacts.
The new substation employed over 100 local contractors while it was built and is a key part of our annual capital works program.
As one of the most modern substations on the network, Macarthur is now a valuable part of the national electricity grid.
