Review of Environmental Factors

Ausgrid is responsible for assessing and approving works for the Summer Hill zone substation project. This process includes preparation of an environmental assessment (Review of Environmental Factors or REF). The REF includes a range of specialist studies and input from the community, councils and other authorities. The REF was on exhibition for comment from Thursday 14 December 2017 until Monday 22 January 2018.

The project has now been approved for construction. Please click on the links below to view the final REF.
