BESS
BESS
The project will be known as the ‘Sunshine Estate BESS’ and will be located approximately 3 km southwest of North Rothbury, adjacent to the Ausgrid Rothbury substation.
The purpose of the development is to assist the national electrical grid at times of peak demand and in times of emergency. The project will be constructed on private land, approximately 3 kilometres southwest of North Rothbury, NSW. The 120MW / 480MWh BESS project will be located on a development site of approximately 7-hectares and will connect directly into the 132kV Rothbury substation located to the southeast on an adjacent site.
Construction and operation of the project would involve the following key components:

Given the significant potential that the development has in contributing to the clean energy transition and climate action targets of the state, the Sunshine Estate BESS proposal has been classified as a State Significant Development (SSD) by the NSW Department of Planning, Housing and Infrastructure (DPHI).
During the early stages of the development application process, a Scoping Report was submitted to DPHI in September 2025 to identify the technical studies and key assessment areas to be addressed within the Environmental Impact Statement (EIS). Following DPHI’s review and evaluation of the Scoping Report, the Secretary’s Environmental Assessment Requirements (SEARs) were issued on 1 October 2025, outlining the specific matters to be addressed in the EIS, including environmental, social, and technical considerations.
With the SEARs now in place, the EIS preparation phase is underway. The EIS will provide comprehensive documentation of specialist assessments and detailed planning information relating to the Sunshine Estate BESS, addressing all requirements specified within the SEARs. Once completed, the EIS will be submitted to DPHI for assessment, after which the Minister for Planning will determine whether to grant development consent for the Project.
You can find the Scoping Report and SEARs on the NSW Major Projects Portal

The Sunshine Estate BESS will improve energy security by reducing the risk of power outages in the region whilst ensuring firmed power supply to the local network.
During the construction phase an estimated 100-130 workers will be required with a large proportion of these being local contractors and suppliers wherever possible.
The operational phase will create up to 3 ongoing full-time roles for the approximate 35-year lifetime of the BESS.
The BESS represents a positive diversification of the local economy and will bring investment to the area. It will deliver additional indirect economic opportunities to local businesses including local grocery stores, restaurants, cafés, accommodation providers, petrol stations, vehicle servicing, pubs, catering, cleaning companies, tradespersons, tool and equipment suppliers and many other businesses.
Avenis Energy is committed to supporting community benefit schemes in the local area and value the opportunity to make a positive impact. We welcome any suggestions and look forward to collaborating with local partners to ensure our efforts align with the community's needs.
While community information sessions are one way to share your views, we understand they don’t suit everyone. That’s why we’re providing multiple opportunities for you to have your say.
We encourage you to complete the Community Feedback Survey. We welcome input from all members of the community and will continue to offer flexible ways for you to share your thoughts throughout the project. The survey closes at 4:00 pm AEST on 9 July 2025.
Avenis Energy are hosting two community information drop-in sessions that will be held in June 2025. Members of the team will be there to discuss the Project and answer questions. The details of the information sessions are:
