Gold Road to choose renewable energy for mining innovations

Gold Road is a mid-tier Australian gold producer with exploration projects in the underexplored and highly diversified Goldfields. Gold Road is executing an industry leading exploration strategy for gold mineralisation at Yamarna.

With the aim of reducing the dependency on diesel for power generation, reducing the cost and resultant greenhouse gas emissions, this gold mining company depends on Unlimited Energy Australia for designing an economically viable solar renewable energy solution for the Yamarna mining exploration camp which 1200kms east of Perth.

They were looking for a solution that required minimum impact on the environment, future expansion capacity, easily movable infrastructure and to provide a payback period under 5 year.

Unlimited Energy Australia conducted a feasibility study and then designed an economically viable hybrid smart-grid solution for Yamarna exploration camp. It is an Off-grid hybrid PV with 187 KW solar PV array comprising 580 modules with 60 cells each and a 408kWh Tesvolt Lithium-Ion Battery System.

Unlimited Energy Australia designed and installed Solar PV array and energy storage hub. They opted for a modular design as it has future expansion capacity and can be easily moved. The modular energy hub design enabled fabrication to be completed off-site. It helped in a quicker installation as well.

To eliminate the risk of battery storage technology, they chose Tesvolt lithium- ion battery as it is the safest on market. It has long-term performance warranties and batteries and are tried and tested to suit the harsh conditions experienced at the camp site.

This off-grid solar PV system will offset approximately 70% of the camp’s diesel consumption and deliver environmental and cost benefits to the remote operation in Western Australia’s north-eastern Goldfields. The hub was officially opened by WA Minister for Mines and Petroleum, Bill Johnston, at the end of last year.

The benefits of this off-grid solar PV system are:
• minimum impact on the environment
• modular design
• ability to relocate
• economic viability
• extendibility of the system

Gold Road is planning a 50-50 joint venture with Gold Fields. They plan to install a hybrid microgrid at the nearby Gruyere gold project, with a 13 MW solar farm, a 4 MW gas engine and a 4.4 MWh battery energy storage system in 2021.This project is expected to increase the mine’s power capacity, reduce costs and increase plant output.

Western Australia Energy Minister Bill Johnston appreciates Gold Road Resources and Gold Fields for opting for renewable energy technology and for being committed in transitioning to a low carbon future.
Gold Road Resources’ investment in renewable energy to power Yamarna camp and Gruyere gold project supports WA’s global reputation as a leader in mining innovation.
