Project Overview

Proposed solar & energy system south east of Dubbo

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).
The Project is subject to approvals and is currently in the planning stages. Assessments are commencing to help inform the Environmental Impact Statement (EIS).
Subject to approvals, 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.
