Goldfields Regional Network

The Goldfields are rapidly becoming an international hub for the resources that underpin the technologies at the heart of the global clean energy transition. To play this new role, the region will need upgraded electricity infrastructure and secure and reliable local energy.

That’s why the State Government is investigating the Goldfields Regional Network (GRN) concept – a new common use transmission network that would connect world-class renewable resources in the Goldfields to industrial centres and local communities.

How would it work?

The GRN would connect renewable resources to where electricity is used. This would allow industry in the Goldfields to access low emissions energy, ensuring the supply of electricity in the region is able to meet future demand.

Investigating the GRN

Development of the GRN is progressing through a structured process aimed at exploring the concept’s feasibility and potential benefits, while engaging with local industry and Aboriginal people.

Three-Stage Investigation

Stage One: Concept Study

A high-level economic assessment that confirmed the GRN as the least-cost solution for meeting energy demand in the region.

The assessment modelled a five-node structure (Leinster, Leonora/Laverton, Boorabbin, Kalgoorlie and Kambalda), across three different demand scenarios to make an initial assessment of the viability of the GRN.

Working Together

PoweringWA is actively engaging with local stakeholders to investigate the best possible solutions for the GRN. To ensure meaningful consultation as the GRN project progresses, PoweringWA has established a Commercial Working Group. This group is consultative in nature – acting as a platform for information sharing and advice.

In parallel to the Working Group, PoweringWA is undertaking structured engagement with Aboriginal stakeholders. The outcomes of this engagement will help shape the GRN project while also ensuring local Aboriginal groups have meaningful opportunities to participate in and benefit from the GRN project.
