WA iron site to run green
Government funding has been provided for Australia’s first Solar Gas Hybrid project.
The funding should see Western Australia’s Pilbara region host the first major iron ore mining operation in Australia to be run entirely off renewable energy during the day.
The Australian Renewable Energy Agency (ARENA) has announced $24.2 million in funding to Alinta Energy Pilbara Finance Pty Ltd to develop its Solar Gas Hybrid project to power Fortescue Metals Group’s Chichester mining hub.
As part of Alinta’s project, a 60 MW solar PV facility will be constructed and approximately 60 kilometres of new transmission lines will link Fortescue’s Christmas Creek and Cloudbreak mines with the new solar farm.
The project will also see the transmission lines connect the Chichester Hub’s mines and Roy Hill to Alinta’s existing 145 MW gas-fired Newman Power Station and its 35 MW / 11 MWh battery storage system.
Fortescue is to be the offtaker of the project which will help to reduce the use of diesel by around 100 million litres annually, as the mines currently rely on diesel generators.
This will allow up to 100 per cent of daytime energy requirements for the Chichester iron ore mining operations to be powered by renewable energy, with the remaining power requirements to be balanced with gas generation.
The Northern Australia Infrastructure Facility (NAIF) will also provide a loan of up to $90 million.
ARENA CEO Darren Miller said the project could unlock further investment in renewable energy in the mining sector and other remote and energy intensive operations.
“Alinta’s project will demonstrate how renewable energy solutions can deliver critical energy requirements for major mining operations and help reduce emissions,” he said.
“This will also show how interconnection of loads and different generation and storage – including solar, battery storage and gas – can provide secure and reliable electricity.”
Construction is expected to commence before the end of the year and be completed by mid-2021.
