The Hunter-Central Coast (HCC) REZ was declared by the NSW Minister for Energy under section 19(1) of the Electricity Infrastructure Investment Act (EII Act) in December 2022. In April 2025, the Consumer Trustee authorised Ausgrid to carry out the HCC REZ network infrastructure project (RNIP).
The HCC RNIP is expected to provide an additional 1 gigawatt of new network transfer capacity by 2028 to support renewable energy generation and storage within the HCC REZ region.
