There are changes to Australia's electricity system and as part of that, battery storage is becoming an essential part of keeping the power grid reliable. The proposed Lake Road Battery Energy Storage System (BESS) will store electricity when it is plentiful and release it when demand is highest, helping support reliable power supplies across NSW and making better use of renewable energy.
The Lake Road Battery Energy Storage System (BESS) is proposed to be a large-scale electricity storage facility at 71 - 77 Lake Road, Tuggerah.
It would support the NSW electricity infrastructure through connecting to the Transgrid high-voltage transmission network at the Tuggerah Substation adjacent to the site. The battery facility will serve to store surplus electricity from the grid when it is abundant and release it when it is needed most.
By balancing supply and demand, the project will improve grid reliability, support the integration of renewable energy, and help deliver a cleaner, more resilient electricity system for New South Wales.
The project is owned by Lake Road Battery Company, an Australian owned company that brings together the experience of Smart Commercial Solar

71-77 Lake Road, Tuggerah NSW 2259
The Lake Road site was identified because of a combination of factors that make it well-suited to a large-scale battery energy storage facility.
The site sits directly next to the existing Transgrid substation, enabling a direct and efficient grid connection.
The land is already zoned for industrial use, making it an appropriate location for this type of infrastructure.
Transmission lines and substation capacity are already in place, reducing the need for new infrastructure.
The existing network can accommodate the facility's connection without significant augmentation works.
The site is located within an industrial area, separated from residential neighbourhoods.
The site requires limited clearing of native vegetation, reducing the environmental footprint of the project.
Lake Road provides direct industrial-grade access to the site, suitable for construction and ongoing maintenance.
The site's flat terrain and dimensions are well-suited to the layout requirements of a battery storage facility.
The project will progress through the NSW State Significant Development planning process. Below is the expected sequence of steps and timing.
The Lake Road BESS will deliver a range of benefits to the electricity system and to the broader community.
Stores surplus renewable electricity that would otherwise be wasted, enabling more solar and wind energy to be used effectively.
By connecting to existing infrastructure at Tuggerah Substation, the project reduces the need for new transmission infrastructure.
The project will create local employment opportunities during the construction phase.
Helps balance supply and demand on the network, reducing the risk of blackouts and voltage fluctuations.
Reduces reliance on expensive gas peaking plants during high-demand periods, helping to moderate wholesale electricity costs.
Battery storage is critical infrastructure for a modern electricity grid. Here is how this facility fits into the system.
Solar farms and wind turbines across NSW generate electricity and often produce more than is needed in real time. This surplus pushes prices down on the wholesale electricity market, and without storage, much of it is wasted.
The 1,600 MWh of battery capacity charges from the grid when electricity is cheap and abundant, absorbing renewable energy that would otherwise be lost. The facility is planned to be connected directly to the Transgrid high-voltage transmission network.
During peak demand, typically early evenings or during extreme weather events — the battery discharges into the Transgrid network, stabilising frequency, supporting voltage, and reducing the risk of widespread outages.
More grid stability means lower wholesale price spikes during peak periods, less reliance on expensive gas peaking plants, and a more reliable electricity supply for homes and businesses across the Central Coast and beyond.
How energy flows through the system
The facility will use Sungrow's Power Titan 3.0 battery system, a proven utility-scale technology that is operating in battery energy storage projects around the world.
Each battery unit is a fully integrated cabinet that houses the battery cells, power conversion equipment, cooling system and built-in fire protection. Every unit is factory assembled, tested and certified before being delivered to site, ensuring consistent quality, reliability and safety.
Lithium iron phosphate (LFP) battery chemistry has been chosen because it is one of the safest lithium battery technologies available. Unlike other chemistries commonly used in consumer electronics and some electric vehicles, LFP batteries are less likely to overheat. LFP is widely used in large-scale energy storage systems where safety, reliability, and long service life are important.
