Neoen’s 150MW/193.5MWh battery storage facility Hornsdale Power Reserve in South Australia has secured approval from the Australian Energy Market Operator (AEMO) to deliver inertia services to Australia’s National Electricity Market.

As with vehicle suspension on an uneven road, inertia services are essential for stabilising the grid when electricity supply and demand fluctuate. Hornsdale Power Reserve has been upgraded with Tesla’s Virtual Machine Mode, which allows the advanced power inverters to emulate the existing inertia services being supplied by an ageing fleet of fossil fuel power plants. The level of inertia that would be provided by Hornsdale Power Reserve could match half of the total needs of South Australia.

Hornsdale Power Reserve is the first big battery in the world to deliver grid-scale inertia services, thanks to Tesla’s pioneering Virtual Machine Mode technology. Batteries now have the capacity to provide these services at scale, as gas and coal-fired generators have traditionally done.

It comes after two years of extensive trials and intensive collaboration with Tesla, AEMO and ElectraNet, supported by the South Australian Government, ARENA and CEFC.

Neoen Australia managing director Louis de Sambucy said, “We are delighted to announce the successful deployment of inertia at Hornsdale Power Reserve. This achievement was forged through outstanding teamwork. I’d like to acknowledge the dedication of our team and our long-term partners at Tesla, as well as our trusted counterparts at AEMO and ElectraNet.

“It was made possible through the support of South Australian Government, and of the Australian Government via ARENA and CEFC. In pioneering the delivery of grid-scale inertia, Neoen continues to lead the way in battery storage innovation, reinforcing its contribution and commitment to South Australia’s 100 per cent renewable energy target.”

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

The project is co-located with Hornsdale Wind Farm.
