The global mining giant Rio Tinto has contracted EDL, the developer of world-class wind and solar projects across Australia, to expand an existing solar installation at its Weipa bauxite mines in Queensland by adding 4 MW solar power generating capacity and 4 MW/4 MWh of battery storage.

The renewable energy project developer EDL will build, own and operate the new facilities, with plans to accomplish them by late 2022. It also owns and operates the existing 1.6-MW solar farm at Weipa that was concluded in 2015.
Michelle Elvy, General Manager for Rio Tinto Aluminium Pacific Bauxite Operations, said: “The new solar farm and battery storage at Weipa will help us lower our carbon footprint and diesel use in a reliable way.”
“The original Weipa solar farm was the largest solar facility at an off-grid Australian mine site at the time it was built, and it played an important role in showing the viability of renewable energy systems in remote locations.
“The new solar farm and battery storage system is part of Rio Tinto’s group-wide commitment to reduce emissions across our operations. There is more work to be done, but projects like this are an important part of meeting our climate targets.”
EDL Chief Executive Officer James Harman said: “We welcome the opportunity to continue supporting Rio Tinto to reduce carbon emissions."
“EDL will be leveraging expertise from our hybrid renewable energy systems around Australia to deliver clean and reliable energy for Rio Tinto’s operations and the local community.”
Following the completion of the project, the combined 4MW solar capacity and 4MW/4MWh battery will provide about 11-gigawatt hours of energy annually. In combining with upgrades to the existing Weipa power generation network, the development will restrict Weipa Operations’ diesel consumption by an estimated 7 million litres per year and reduce its annual carbon dioxide emissions by about 20,000 tonnes, which is equivalent to off-roading more than 3,750 cars.
