Mornington BESS
240MW/480MWh utility-scale battery energy storage system project.

Scheduled for completion in 2022, Mornington BESS is a utility-scale Battery Energy Storage System (BESS) located in Victoria’s Mornington Peninsula.

Our commitment to a brighter future.

The battery system will store approximately 480MWh of electricity, which will power more than 40,000 homes.

Mornington Battery Energy Storage Project (The Mornington BESS) involves the development of 240MW/480MWhr utility scale battery energy storage system. The Mornington BESS Project is located adjacent to AusNet Services' Tyabb Substation, where the BESS will connect to the National Electricity Market.

The Mornington BESS would provide the following benefits, specific to Australia’s commitments

Reduction in greenhouse gas emissions required to meet our clean energy transition

Additionally, the proposal would allow for the:

  • Provision of embedded electricity generation, to supply into the Australian grid closer to the main consumption centres
  • Provision of social and economic benefits, through the provision of direct and indirect employment opportunities during construction and operation of the project

The site address is located on 6.7 hectares of pasture on Thornells Road, Tyabb, adjacent to AusNet’s Tyabb substation.

The site is located within the Mornington Peninsula Shire Local Government Area and on land zoned Special Use Zone (for port related uses).

The site was chosen because of its proximity to the substation. This site also has good road access and comprises flat land that is largely cleared of native vegetation and is suitable for the proposed BESS.


Maoneng commenced consultation with near neighbours, Council and other key stakeholders late last year prior to lodging a planning permit application with the Victorian Department of Environment, Land, Water and Planning in December 2020.

The application will consider the full scope of potential environmental and amenity impacts, and include specialist technical studies for ecology, surface water, traffic, visual amenity, noise and hazards. Public exhibition of the application is expected to commence in March or April. Interested parties will be notified by mail to near neighbours, signs erected to site and notices in the local newspaper and are able to lodge a submission to the Department at this time. The community is encouraged to engage with Maoneng regarding any queries they have.

Community Benefits

Engagement with the local community is an important value of Maoneng and is integral to this project. We would like to ensure that open dialogue and information transfer can occur with local residents, stakeholders and the wider community in an easy and efficient manner.

We would like to ensure that there is no “surprise” to the community and that a long-term relationship is maintained between the project team and all project stakeholders.
