Blackstone Battery Energy Storage System (BESS) Project

Australia · Energy

In-depth research Release 1

Project scope

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.

Reported status and procurement

Reported development: Not established
Procurement availability: Unknown / not established

Reported procurement

Plan: Execution of the EPC and Long-Term Service Agreement (LTSA), and execution of connection and access agreements with Powerlink Queensland for the Blackstone Substation extension and high-voltage underground cables, are listed as future steps. The description does not state that these agreements have been executed.

Reported regulatory context

The portal displays project status “Referral Decision Made,” while the project description lists finalising Operational Works approvals with Ipswich City Council as a future step; neither establishes that all approvals are complete. The captured page states it is an offline, read-only version and warns that project status fields for some projects may update. The related-decisions table shows loading, permission and error messages and provides no usable decision details.

Reported financing

Plan: Completing project financing and achieving financial close are listed as steps to be completed following the EPBC Act referral.

A source report alone does not establish current progress or an open buying window.

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.
