Narrogin BESS project is located on land that has already been largely cleared for farming purposes in the past. South Energy plans to retain most of the remaining native vegetation which will be put in protected zones. South Energy expects no vegetation removal except weeds and brushes over the construction areas and if needed few trees at the boundary of the site, which would be required to allow access for construction vehicles. Thus, there will be no impact on any listed species. South Energy has engaged an accredited ecologist to ensure the protection of areas of ecological significance during both the construction and operation of the BESS project.

The first stage of the project will cover about 20% of the site area. The remaining will continue to support agricultural activities, considering the future expansion plans.

A preliminary surface water study is undertaken as part of the project’s feasibility study. The results showed that surface water traversing the site is generally slow, shallow and wide-spreading. Any risk identified in subsequent studies will be taken into account in the project design to eliminate and mitigate any negative impact due to the proposed BESS structures.

Structures within the BESS project is easily installed and do not affect groundwater. A hydrology assessment will be conducted, and the findings will be reflected in the designs to manage water routes and avoid any impact on or from the BESS project.

Any weeds found around the BESS project’s components would be controlled regularly. Narrogin BESS project would employ vegetation management personnel from time to time to monitor and control the weeds as part of the operation and maintenance protocols. Where practical, sheep grazing at the site and around the non-construction area may be utilised as an effective and environmentally friendly way to control weed growth.

BESS project footprint consists of the battery storage zone, substation and control building zone, and operation and maintenance zone, which will be constructed over an area of around 5 ha.

BESS components are contained in modular cells which in turn are containerized. They will be installed on concrete pads or footings that are similar to those used for substations or even residential dwellings. Underground cabling will be installed by trenching and backfilling the ground. During decommissioning, the cables will be unearthed and recycled.

South Energy understands the importance of fire risk management and will always put the public’s safety first. The design for the Narrogin BESS project will be consistent with Country Fire Authority guidelines in consultation with local authorities as applicable, with a firebreak (which also acts as an access track) built within the BESS project and along its boundary. South Energy will work with consultants and relevant authorities to conduct the bushfire management plan, risk management plan and emergency plan.
