Why choose Bannaby for battery storage
Balancing Supply and Demand
Our battery system bridges the gap between Australia's renewable generation zones and metropolitan demand centres, providing critical storage capacity where it's most needed. By capturing excess generation and delivering power during peak periods, we optimise the flow of electricity across the national network.
Enhancing Energy Security
Strategically positioned on Sydney's 500kV transmission ring, our facility strengthens the reliability of Australia's evolving power network. This advanced storage system provides critical support to major population centres while enabling greater integration of regional renewable energy resources.
Supporting Net Zero Ambitions
Recognised by the Australian Energy Market Operator (AEMO) as essential electrical infrastructure, battery storage plays a pivotal role in Australia's energy transformation. Our facility enables broader adoption of renewable generation across the network, supporting the nation's pathway to lower emissions and more affordable energy.
As a critical enabler of clean energy integration, battery storage supports the transformation of Australia's power infrastructure while ensuring reliable supply across the network.
Detailed overview of the proposed site
Location
Positioned at a key power distribution point near the Transgrid Bannaby substation, our site encompasses 13 hectares within a broader 305-hectare pastoral property. Currently used for cattle and sheep grazing, this carefully selected location offers optimal grid connectivity while maintaining the surrounding agricultural activities. The site's proximity to existing power infrastructure ensures seamless integration with minimal environmental impact.
Landscaping
The site's pastoral setting offers natural advantages for infrastructure integration, with existing trees and vegetation to be preserved alongside continued agricultural use. Our landscape design incorporates strategic planting of additional native trees and vegetation to enhance natural screening, particularly along Hanworth Road viewpoints. These carefully selected plantings will harmonise with the local ecosystem while providing effective screening of the facility, with detailed improvements to be fully documented in our planning submission.
Accessibility
Site access will be provided via a new dedicated entrance from Hanworth Road, chosen to minimise impact on local traffic patterns. This location optimises accessibility to the Transgrid easement, facilitating efficient connection to the Bannaby Substation. The site's topography and proximity to existing infrastructure has been carefully considered in our access planning, ensuring minimal disruption during both construction and operational phases.
Operations
The facility operates through sophisticated remote monitoring systems, requiring only monthly maintenance visits. This automated approach ensures efficient operation while maintaining minimal local traffic impact, complementing the site's continued agricultural use. Operational activities are designed to integrate seamlessly with the existing pastoral functions of the broader property.
Bannaby's Strategic Advantage
.avif)
Proximity
Direct connection to the Transgrid Bannaby substation (500kV/330kV) maximises operational efficiency while minimising network modifications. The site's immediate proximity to existing infrastructure and Transgrid easement enables rapid deployment of essential storage capacity to the grid.
Regional Needs
Strategically positioned between the South West Renewable Energy Zone and Sydney's metropolitan area, this location optimises power distribution across the network while strengthening grid resilience. The site's position on Sydney's 500kV transmission ring ensures efficient energy transfer between generation and consumption centres.
Environmental Compatibility
The 13-hectare facility, thoughtfully positioned within a 305-hectare pastoral property, demonstrates our commitment to balanced land use. The site's natural pastoral setting and established access routes create an ideal environment that complements existing agricultural activities while supporting essential energy infrastructure.
Integrated Ecological Design
Enhanced Biodiversity Design
Building on detailed ecological surveys, our design incorporates features specifically for local wildlife, including water features, nesting boxes, and indigenous wildflower meadows. These enhancements support native species while working in harmony with the site's existing pastoral character.
Natural Site Screening
The site's natural topography and existing vegetation provide effective visual integration within the pastoral landscape. Additional native planting will further enhance the natural screening, particularly along Hanworth Road, minimising visual impact on the surrounding area.
Operational Excellence
Advanced remote monitoring systems ensure optimal performance with minimal physical presence. The facility operates with carefully monitored noise controls, with cooling systems designed to meet appropriate standards and guidelines. Monthly maintenance visits maximise operational efficiency while maintaining minimal local impact.
