Environmental Assessments

​​The NSW Government has prescribed Authorised Network Operators (ANOs), which includes TransGrid, as a prescribed determining authority. This allows us to assess and self-determine proposed activities that are not likely to significantly affect the environment.

We will ensure that environmental assessments under Part 5 of the NSW Environmental Planning and Assessment Act 1979 (EP&A Act) are carried out in accordance with the NSW Code of Practice for Authorised Network Operators.

The Code has been developed by the NSW Government to ensure that Part 5 environmental assessment are conducted appropriately and in a manner that supports proper environmental assessment including appropriate community consultation.

The environmental assessments for specific projects can be located by visiting our current projects.

The NSW Code of Practice for Authorised Network Operators 2016 requires Authorised Network Operators to publish a consultation protocol setting out the process it will follow when conducting environmental impact assessments for Class 4 and 5 Activities (as defined in the Code). 

TransGrid refers to these environmental impact assessments as a Review of Environmental Factors (REF). This protocol provides a tailored approach to consultation when preparing REFs and includes consultation with members of the public, the Secretary of the Department of Planning and the Environment and Government Authorities.
