Apsley BESS

Welcome to the Apsley Battery Energy Storage System (BESS) Project website.

Apsley BESS is an approved 120 MW, four-hour energy storage project located approximately 10 kilometres south of Wellington in the Dubbo Regional Shire. The project will connect to the existing New South Wales high-voltage transmission network and contribute to a more reliable, secure and diverse energy system.

Here, you can learn more about our plans and proposals, the planning and assessment process, and how to stay informed or provide feedback as the project develops.

The PROJECT

The project

Artist impression

Location

Apsley (Orana), Dubbo Regional Council, New South Wales

Capacity

120 MW / 480 MWh

Land size

6 hectares

Jobs

Creating up to 100 construction jobs, with 2 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

Project update – public exhibition now open

The Apsley Battery Energy Storage System (BESS) was approved in 2023, and detailed design is currently underway. Construction is anticipated to commence at the end of 2026, subject to approval.

The proposed modification is now on public exhibition from 18 June to 1 July. As part of this process, the project seeks approval for the following changes to support its delivery and operation:

1. Increasing the duration of energy storage from 2 to 4 hours
2. Increasing the peak construction workforce from 50 to 100 full-time equivalent workers
3. Extending the construction period from 5 to 18 months
4. Upgrades to the local road intersection

The modification does not change the approved location of the project.

Community members are invited to review the modification and make a submission during this period. For more information:

Why Apsley

Site selection

Proximity to infrastructure

The location of the project was selected for its direct access to the existing high-voltage transmission lines on the site. Direct access to the transmission network reduces the amount of infrastructure needed to connect.

Regional profile

The project is located in a region characterised by high quality solar resources. The project is able to store energy produced during the day which can be used during peak periods in the evening.

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

Why battery storage

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, batteries help optimise the flow of electricity across the national energy network.

Enhancing energy security

Battery systems can change 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.

ENVIRONMENTAL Excellence

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.

Battery storage supports the reliability and stability of the NSW power system, helping ensure a consistent supply of electricity for homes, businesses, and communities.

08
Community Outcomes

Community benefits

Construction of the project is anticipated to require a workforce of up to will 100 full-time equivalent jobs, many of whom will be locally based.

Funding will be provided to Dubbo Regional Council from the commencement of operations in support of the community.

Funding will be provided to Dubbo Regional Council:

a payment of $120,000 at the commencement of operations

a further payment of $230,000 at the start of the fifth year of operations
