Goulburn River Solar Farm

HP Profiles supplied HPP-PE48S split HDPE conduit to the Goulburn River Solar Farm, one of Australia's most significant utility-scale renewable energy projects currently under construction in the Upper Hunter Region of New South Wales.

‍

The project is being developed by Lightsource bp, a bp company, and sits between the villages of Wollar and Merriwa, on Wollara Road. At 585MWdc installed capacity, it represents an estimated capital investment of A$880 million, with the EPC contract awarded to DT Infrastructure, a wholly owned subsidiary of Gamuda Berhad, valued at A$625 million.

‍

Construction commenced in December 2024 and is expected to span approximately 27 months, creating up to 350 construction jobs during that period. Once operational, the farm will generate approximately 1,309,000 MWh of renewable electricity per year, enough to power the equivalent of 225,000 Australian homes, while avoiding an estimated 910,000 tonnes of CO2e annually and meeting up to 4% of NSW electricity demand at peak output.

‍

The solar farm will comprise approximately one million bifacial solar panels mounted on ground-level single-axis tracking structures, connected to an onsite substation via an underground cable network. Around 140 inverters will convert DC to AC power before transmission to the grid via Transgrid's existing 500kV transmission line. The project also includes a Battery Energy Storage System to shift renewable generation into night-time peaks and support grid stability.

HP Profiles' HPP-PE48S 48mm split HDPE conduit was selected for its suitability in large-scale solar cable management. The split design allows fast, efficient installation over existing cabling runs without the need to thread cables through, making it well suited to the extensive cable protection requirements across the project's approximately 1,996-hectare footprint.
