Overview
The Nook Battery Energy Storage System (BESS) will have a power capacity of up to 280 MW, capable of storing up to 560 MWh of energy. The system will support the electricity grid by delivering essential services such as frequency control and load shifting—both critical for enabling higher levels of renewable energy integration.
It is anticipated that the system’s output will be contracted to optimise the use and performance of the technology, ensuring maximum benefit to the grid and consumers.
Battery storage: powering flexibility
A Battery Energy Storage System (BESS) is a large-scale system that stores electricity for use when and where it’s needed most. Think of it as a giant rechargeable battery that helps stabilise the grid and makes renewable energy more reliable.
Project Location
Strategically positioned near Poatina in Tasmania for optimal grid integration

Strategic Location
The Nook BESS will be located approximately 6 km north of Sheffield, in northern lutruwita/Tasmania, on the traditional lands of the Moomairremener people.
It will connect to the TasNetworks transmission network via the adjacent Sheffield Substation, a critical node in the Tasmanian electricity system. This proximity minimises the need for additional transmission infrastructure, reducing visual and environmental impacts and supporting efficient grid integration.
