Overview
The Hazelwood Battery Energy Storage System (HBESS) is a 150MW/150MWh utility-scale battery that delivers further electricity grid stability for Victoria. It has the capacity to store the energy equivalent of an hour of energy generation from the rooftop solar systems of 30,000 Victorian homes, playing a critical role in increasing the state’s energy capacity and delivering further grid stability. As an established power generation site with access to 1,600MW of dormant transmission capacity, Hazelwood is uniquely placed to accommodate battery infrastructure.
Situated near the former site of Hazelwood Power Station in the Latrobe Valley, the Hazelwood Battery forms part of ENGIE’s commitment to repurposing the site, which ENGIE has been rehabilitating since 2017. The battery’s innovative design and the site’s unique location provides the potential to scale up storage capacity quickly and cost-effectively in order to respond to network and market demand.
Battery storage serves a key role in accelerating the build-out of solar and wind resources, capturing excess power during periods of high energy generation while discharging to meet peak demand. The Hazelwood Battery will also participate in frequency control ancillary service markets, delivering critical stability to a grid increasingly comprised of intermittent renewable sources.
Key Figures
The Battery:
- 150 MW/150 MWh utility-scale battery-based energy storage system - intended as a grid stability and peak power asset. This means the battery will be able to send extra electricity into the grid in times of peak demand, or store electricity that is not being used in times of low demand.
- The project is funded by ENGIE and Eku Energy, and will be built, operated, and maintained over a 20-year period by Fluence, a global market leader in energy storage products and services and digital applications for renewables and storage.
- The battery uses Fluence’s latest-generation Gridstack technology platform - made of 342 modular, standardised factory-built Fluence Cubes - providing industry-leading reliability and safety at all levels of the system.
- The battery has an expected lifespan of 20 years.
