South West Renewable Energy Zone

The South West Renewable Energy Zone (SW REZ) is a cornerstone of New South Wales' transition to a sustainable energy future. Spanning from the Dinawan Substation in the east to the Buronga Substation in the west, this zone is strategically positioned to harness the region's abundant wind and solar resources. The SW REZ is expected to unlock 3.56 gigawatts (GW) of clean energy generation capacity, capable of powering up to 1.6 million homes.

Business Supply Survey

The Energy Corporation of NSW (EnergyCo), in collaboration with Arup, is working to understand the opportunities for businesses who could work to support renewable energy projects in the area around the South West Renewable Energy Zone (REZ).

As part of this project, we are conducting a business survey to gather essential insights from local businesses regarding their capacity and constraints in supporting the delivery of the programme of projects in the South West REZ.

The purpose of this survey is to better understand how to ensure businesses like yours can capitalise on the opportunities that will be presented through these projects. The data collected form this survey will be de-identified, aggregated and only used to inform recommendations that will seek to benefit businesses in the South West REZ region.
 
The survey takes approximately 5 minutes to complete
