Power Transmission & Storage

Transforming the energy grid and enabling a low emission power supply for future generations

Downer is one of Australia’s largest and most experienced contractors to the transmission and renewable energy sector, delivering power systems projects nationally for both utility and private developers.

We have longstanding relationships with electricity transmission network operators and with more than 50 years in the industry, have built thousands of kilometres of transmission lines across Australia.

We have the capability to connect and upgrade the capacity of the existing network infrastructure to support all future energy projects and supply new energy into the network. 

Our in-house power systems design house is one of the largest within Australia, which means our expertise is engaged early to deploy the full suite of construction knowledge for large scale, complex infrastructure projects. 

We provide full end-to-end service of design, procurement, project management, construction, commissioning and complete operations of substations, transmission lines, solar and wind farms, and Battery Energy Storage Systems (BESS).
