NSW battery changes are coming — is your team ready? 🔋
With the proposed BESS3, BESS4 and BESS5 activities commencing from 1 September 2026, each activity comes with different eligibility, evidence and project requirements.
We’ve broken down the proposed requirements into a practical, installer-focused guide so you can see at a glance what applies to:
🏢 BESS3 — Apartment Buildings
🏪 BESS4 — Small & Medium Business
🏭 BESS5 — Commercial & Industrial
From site and business evidence to geo-tagged photos, installer requirements, approvals and activity-specific conditions — knowing what you need before the project starts can help reduce RFIs and keep claims moving.
