South Australia’s Big Battery

Clean energy for SA

Sharing Benefits

Making a difference in local communities

OVERVIEW

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

The first 100MW/129MWh 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 50MW/64.5MWh expansion was completed in September 2020. As part of the expansion the full 150MW is being upgraded to include Tesla’s Virtual Machine Mode, enabling the battery to provide inertia support services to the electricity grid.

BATTERY

Battery storage allows us to store the energy and provide it to the grid whenever it’s needed.

LOCATION

The Hornsdale Power Reserve is located in a strong part of South Australia’s electricity transmission network approximately 15km north of Jamestown, about 3 hour’s drive from Adelaide.

The project is co-located with Hornsdale Wind Farm

This graph with live data indicates how much power the battery has charged (left axis, blue bars) and discharged (left axis, pink bars) in the past 48 hours as well as the electricity price (right axis, black line).

Neoen produce affordable reliable electricity from natural renewable sources such as the sun and wind.

With 12 years’ experience behind us, our technologies are tried, tested and proven. Our South Australian Big Battery has been keeping the lights on in SA since 2017, and saved consumers over $116 million in 2019 alone !

We own and operate all of the projects we build (rather than developing them to be sold) and as long-term neighbours we are committed to sharing the benefits with surrounding communities.

This dedication to community and environment has made us a renewable energy developer of choice across Australia.
