# Blackstone Battery Energy Storage System (BESS) Project Publisher: CapexCue Canonical dossier: Dossier reference: release 1 (217bcbfc-f792-41ca-a80a-31c19cc3912d) Released project intelligence Oldest supporting observation: 2026-10-17T12:07:49.086057+00:00 Dossier released: 2026-10-17T12:27:38.754051+00:00 Source report dates and capture dates are listed per fact below; neither establishes an event date. Original released project name: Blackstone Battery Energy Storage System (BESS) Project. ## Project summary The referral describes a proposed 500 MW / 2,000 MWh standalone battery storage project at 45 Patrick Street, Swanbank, Queensland, with an approximately 7.25 ha footprint and associated substation, underground cables, site infrastructure, batching plant and mine-remediation works. Approximately 3.26 ha of mapped koala habitat is within the footprint; 2026 surveys identified habitat resources but directly observed no koalas. Construction is expected to run from November 2026 to Q1 2029. The portal displays “Referral Decision Made,” but the captured page is offline/read-only, warns that some status fields may update, and provides no usable details in its related-decisions table. The description lists approvals, financing, EPC/LTSA execution and Powerlink agreements as future steps; it does not document an open procurement opportunity. ## Evidence limits and unknowns - The portal capture was observed on 2026-10-17; the source provides no publication date. Current project status after that capture is not established. - The source does not establish whether financing, approvals, agreements or the Q4 2026 milestone have since been completed. - The project description does not state a budget or financing amount. - The related-decisions table provides no usable decision details. Current purchasing availability: unknown. Source-dated plans do not establish current progress or available supplier packages. ## Project metadata Country: Australia Region: Oceania Physical assets: Battery Storage, Electricity Transmission Derived from the exact released evidence; unresolved fields remain unclassified. ## Project category Energy Derived from the reviewed scope statement; delivery stage remains unclassified. Proposed 500 MW / 2,000 MWh standalone battery energy storage facility, with an approximately 7.25 ha project and disturbance footprint. Associated planned works include a new 275 kV substation, 275 kV underground cables to the existing Blackstone Substation, access roads, stormwater infrastructure, an operations and maintenance building, battery and electrical equipment, a temporary concrete batching plant, and mine remediation associated with historical underground tunnels in the eastern portion of the site.
