Miriam Vale Battery Energy Storage System

Project Overview

Miriam Vale Battery Energy Storage System (BESS)

Private Energy Partners is proposing to develop a BESS, to be co-located with the proposed Miriam Vale Solar Farm. 

The BESS will operate for about 30 years and be able to store up to 4,000 megawatt hours (MWh) of energy from both the Solar Farm and the nearby electricity network. It will then be able to discharge up to 150MW into the network for up to eight-hours, when it is needed.

This will help reduce electricity waste and stabilise power supply during low generation and high-demand periods, such as at night. The stored energy can also be used to supply the network during unplanned outages, supporting a more efficient, secure and reliable energy system while helping Queensland transition to a decarbonised energy future.

The projects will also boost the regional economy by employing local people and procuring goods and services from local businesses and contractors, where possible, during construction, operation and decommissioning.  

Our overarching project Fact Sheet, BESS specific Fact Sheet, Frequently Asked Questions (FAQs) and Fast Facts provide more information about the BESS and Solar Farm. These documents will be updated as our project planning progresses.

Project status

We have had more than 200 conversations with our site neighbours, the community and key stakeholders, and have incorporated their design recommendations into our project planning. The scale and design of the projects have therefore changed significantly since our BESS and Solar Farm Development Applications (DAs) were lodged with Gladstone Regional Council (GRC) in mid-2024.

These changes, along with the new Planning (Social Impact and Community Benefit) and Other Legislation Amendment Bill 2025, mean our existing DAs are likely no longer relevant in their current form.

PEP has therefore withdrawn the project DAs to finalise updated planning and design, and assess resubmission via the appropriate approval authority.
