The project
Location
Muswellbrook (Upper Hunter), Muswellbrook Shire Council, New South Wales
Capacity
400 MW / 1600 MWh
Land size
9.4 hectares
Jobs
Creating up to 100 construction jobs, with ongoing operational roles and additional workers for routine on-site maintenance
Operations
The project will operate remotely 24/7 for at least 30 years, with routine on-site maintenance. After construction, all temporary work areas will be rehabilitated
Project status
Currently the project team is preparing the Environmental Impact Statement (EIS) which will assess any potential impacts from the project.
Once completed, the EIS will be submitted and displayed to allow for review and determination.
Site selection
Proximity to infrastructure
The location of the project was selected for its proximity to the existing Muswellbrook substation (330KV/132KV). Direct access to the transmission network reduces the amount of infrastructure needed to connect.
Regional profile
This project is positioned in the Hunter-Central Coast Renewable Energy Zone (HCC REZ). It strategically connects the NE REZ generation centre, the QNI (Queensland & NSW Interconnector), and the Sydney load centre.
Site characteristics
The project site has been carefully chosen because the existing land conditions make construction more straightforward, helping to minimise disruption and improve efficiency.
Why BESS
Large-scale battery systems contribute to the stability and reliability of our changing energy system. The energy stored in batteries is able to be used quickly and respond to changing conditions.
Typically, battery systems charge during the day when solar energy is plentiful and release the stored energy back into the grid at night.
Balancing supply and demand
Battery systems help bridge the distance between where the electricity is generated and where it is needed most. By storing excess generation and delivering power during peak periods, batterieshelp optimise the flow of electricity across the national energy network.
Enhancing Energy Security
Battery systems can adapt to changing energy network conditions within milliseconds which assists to provide a more stable and reliable system.
Supporting a diverse system
The way in which our electricity is generated and consumed is changing. Batteries are an essential part of a more diverse and resilient system that is able to respond to change.
Battery storage supports the reliability and stability of the New South Wales power system, helping ensure a consistent supply of electricity for homes, businesses, and communities.
