Risk identification considered both conventional electrical ignition sources and battery-specific hazards. Scenarios reviewed included DC arc faults, switchgear failures, thermal runaway within battery systems, and potential fire spread between energy infrastructure. Particular attention was given to system separation distances, equipment layout, and the interaction between PV and BESS systems within the shared site.
Fire detection and suppression arrangements were also reviewed to determine whether they were appropriate for the expected fire behaviour within each part of the installation. This included assessment of detection technologies, suppression strategies within battery enclosures, and the availability of external cooling resources for emergency responders.
The final deliverable included a prioritised recommendations register outlining practical risk mitigation measures, with clear ownership and suggested implementation timelines. Recommendations addressed areas such as emergency planning, site signage and isolation identification, vegetation management, and coordination procedures between the different asset operators.
The findings were presented during a stakeholder workshop, enabling the project parties to agree responsibilities and establish a shared action plan. The assessment provided clarity on operational risk management and supported both asset owners in strengthening their overall site safety framework.
