FAQs

What technology will be used for the project?

The Hornsdale Power Reserve will utilise Tesla’s Powerpack lithium-ion units and associated equipment. While this is the largest single battery Tesla has constructed, the technology has been proven on a smaller scale at several other sites worldwide. It is also the same technology as is used in Tesla vehicles, meaning that it has been subject to rigorous usage over millions of hours.

Please see https://www.tesla.com/en_AU/powerpack for more detail on Tesla’s Powerpack technology.

When will the Hornsdale Power Reserve be constructed and how long will it take to build it?

Construction is expected to take around four months, with completion anticipated by December 1.

What will be the life cycle of the Hornsdale Power Reserve?

Tesla’s Powerpack 2 units come with an industry-leading 15-year warranty, though the batteries will still retain the majority of their capacity at this time and will be capable of operating beyond it depending on market conditions and other factors.

How will the batteries be disposed of?

Tesla will safely remove all batteries from the site when the facility is decommissioned. Tesla will recycle all returned battery packs and modules at its Gigafactory in Nevada, United States, where over 60% of the materials, especially critical minerals, will be recovered for reuse.
