OZ Minerals to trial hybrid energy solution at Carapateena as part of renewables project

OZ Minerals says it has launched the Energy and Mining Collaboration (EMC) in an initial collaboration with six other organisations to investigate renewable energy and demand management related activities on a mine site.

The six other organisations are Adelaide University, CSIRO, the Department of Energy and Mining, the Rocky Mountain Institute, SunSHIFT and the Tonsley Innovation Precinct.

The first project as part of this program will be a trial installation of a circa-250 kW hybrid energy solution facility including solar, wind and a battery in the first half of 2020, located at OZ Minerals’ Carrapateena mine site in an area demarcated for piloting and prototyping. Carrapateena, in South Australia, is on track for first concentrate production in the December quarter, after which the project will ramp up to full production over the following 18 months. Carapateena is expected to produce an average of 65,000 t/y of copper and 67,000 oz/y of gold over a 20-year mine life.

The trial installation will have approximately 250 kW hybrid energy solution consisting of solar, wind, battery storage, connected to existing diesel generators, and have a Smart Grid controller for data access and tracking.

The EMC brings these organisations together into a collaboration platform with a view to developing and identifying renewable energy opportunities for an international showcase that optimises electrical and fuel demand and the integration of renewable energy systems, OZ said.

“This will be done via the creation of true partnerships around the testing of energy and technology hypotheses to unlock transformational value in mining,” the company added.

“Over the next six months, the parties, as the founding collaborators, are committed to formalising the partnerships from this collaboration, inviting in other first partnership collaborators and creating a broad and global membership of all those who would like to participate.”

South32 powers up Cannington solar PV farm

The new 7,200-panel solar farm at South32’s Cannington silver-lead mine in northwest Queensland, Australia, is up and running, the mining company confirmed.

The 6 ha, 3 MW installation is the company’s first solar installation and will help to deliver reduced greenhouse gas emissions by offsetting gas consumption with solar. Construction commenced in May.

“Electricity generated from the farm will be used to supply the operation’s accommodation village and airport with surplus power used to support mining and processing operations,” South32 said.

The project – which contributes to the objectives of the company’s Climate Change Strategy – is the second largest solar installation in a remote, off-grid mining operation in Australia and the first to be integrated into a gas-fired power station, according to the company.

Earlier this year, EDL Energy signed a 14-year extension of its contract to supply electricity for Cannington, which included partnering with SunSHIFT, a wholly-owned subsidiary of engineering and construction firm Laing O’Rourke, to ‘hybridise’ the existing 34 MW gas plant at the site, with this 3 MW solar photovoltaic installation.

It is anticipated the new solar farm will prevent between 4,000-6,000 t/y of greenhouse gas emissions.

Rob Jackson, Vice President Operations at Cannington, said the operation was committed to identifying energy efficiency initiatives. “Reducing greenhouse gas emissions is a big part of that so I’m delighted that our Cannington operation’s solar installation is leading the way,” he said.

The cost to install and operate the solar farm will be offset by lower fuel costs, according to South32. This makes it an economically viable solution for the operation.
