Storage

Over the next five years, investment growth in short-duration storage will continue to rise then plateau as alternative, longer duration storage options enter the market.

By 2030, Queensland’s energy system is expected to host at least 3.1 GW of short duration batteries or 2.4 GW more than in 2025 and by 2035, an additional 1.6 – 3.4 GW of medium-duration storage compared to 2025.

Signposts

Coordinated Pumped Hydro Energy Storage (PHES) assessment

The QIC Investor Gateway will lead future investigation and investment partnerships with the private sector on all prospective smaller, more manageable PHES projects for the Queensland Government and GOCs. In addition to its ongoing review of Borumba PHES, QIC will take responsibility for assessment of the Mt Rawdon, Big T and Capricornia PHES on behalf of the State’s interest in those projects, including project delivery through to any potential final investment decisions.

This will ensure a consistent approach to assessment, applying a clear value framework to PHES which considers system needs — while enabling CleanCo, Stanwell and CS Energy to focus on core business.

Community batteries

The Government will commit $10 million to catalyse further investment into community batteries across the distribution network, working with Energy Queensland and the private sector to help manage minimum system load during the day, when rooftop solar generation is high and grid demand is low.

Stored energy can be released during evening peaks, reducing reliance on peaking generators, easing network stress and improving overall market efficiency.
