Overview

The Hornsdale Power Reserve is the world’s first big battery. It provides essential grid-support services.

The first 100 MW/129 MWh was completed in November 2017. In its first two years of operation the Hornsdale Power Reserve confirmed the benefits associated with grid-scale batteries in the National Electricity Market and saved South Australian consumers over $150 million.

Following this success, a 50 MW/64.5 MWh expansion was completed in September 2020. As part of the expansion the full 150 MW has been upgraded to include Tesla’s Virtual Machine Mode, enabling the battery to provide inertia support services to the electricity grid.
