Project Overview

Proposed solar & energy system south east of Dubbo

The Hampton Park Solar & Energy Storage System (SESS) is proposed to be built on private land, approximately 11km southeast of Dubbo off the Mitchell Highway.

The Project would consist of a solar and energy storage system with a capacity of approximately 180 megawatt (MW) alternating current (AC) at the point of connection, coupled with a battery storage system of up to 4 hours of storage (approximately 800MWh in total) that would be distributed throughout the Subject Land, rather than within a singular stand-alone configuration. The Project would supply electricity to the NEM.

The Subject Land (i.e. the area under investigation) is approximately 213ha in total.

Subject to approvals, the Project is likely to include the following infrastructure:

  • Single axis tracking PV modules supported by tracker units
  • Solar and battery energy storage inverters / Power Conversion Units (PCU)
  • Medium voltage (MV) transformers
  • Decentralised battery containers dispersed through the solar array with a combined storage duration of approximately 4 hours
  • Project transformer station and switch room, control room, maintenance facility
  • Internal access track and underground/overhead cabling
  • Intersection and road upgrades, as required
  • Security fencing
  • Landscape plantings to soften the view of infrastructure.

Indicative Infrastructure Layout

The Subject Land boundary and Infrastructure Layout is indicative only. The final Infrastructure Layout that will be assessed in the EIS will be informed by community and stakeholder consultation, and detailed environmental investigations.

Project Development Status

This project is in the early planning stages.

A horizontal flowchart shows five steps: Project development and scoping, Request SEARS (with optional scoping report), Prepare and lodge EIS, Department assessment, and Post-approvals.

Development Process & Approval

  • The Hampton Park Solar & Energy Storage System (SESS) is considered as a State Significant Development (SSD) by the NSW Department of Planning, Housing and Infrastructure (DPHI).
  • ARES is currently in the Scoping Phase of the Hampton Park SESS Project, which helps to identify which assessments will be included within the next stage of the Project. It is anticipated that the Scoping Report will be published by DPHI as part of the early stage of the planning process in the coming weeks.
  • Following the submission of the Scoping Report and evaluation by DPHI, Secretary Environmental Assessment Requirements (SEARs) will be issued, outlining required assessments and considerations for the Environmental Impact Statement (EIS).
  • Once SEARs are issued to ARES, community consultation will be undertaken. An EIS is an in-depth document that includes specialist assessments that review a number of technical matters such as noise, social, and environmental considerations of the site. 
  • You can learn more about the SSD and EIS process on the NSW Government’s Department of Planning website.

Connection Agreement

The current agreement is from 2024 to 2026.

Approval by network operator (Essential Energy) to connect to the power grid.

Community Engagement

We are committed to providing the community with clear information and will continue to engage throughout the planning process. Our approach to engagement is focused on fostering respectful, transparent, and lasting relationships with landholders, neighbours, local community members and Council.

Once the Scoping Report is available, engagement will be undertaken with the community.
