Australia’s Largest DC-Coupled Solar Battery Hybrid Project Boosts Evening PV Output

A groundbreaking DC-coupled solar battery hybrid project in Australia has received approval for its grid connection, set to revolutionise solar power generation by extending solar PV output well into the evening peak demand periods.

Octopus Australia announced the grid connection approval for its Blind Creek project, located approximately 30 km northeast of Canberra. The project will boast a 300 MW solar component alongside 243 MW and 486 MWh of co-located, DC-coupled battery storage.

Efficient Energy Storage

DC-coupling allows the solar panels to directly charge the battery without power loss through conversion, enhancing efficiency. This innovative approach enables the project to store excess solar energy during low-priced periods in the day and utilise it during evening peaks when demand and prices are high.

Setting New Standards

The current largest DC-coupled solar battery hybrid project in Australia, located in Cunderdin, Western Australia, is already making a significant impact by providing a steady output well into the evening hours, surpassing traditional solar generation limitations.

Octopus, the developer behind the Blind Creek project, is also constructing another DC-coupled facility in Victoria, further expanding its footprint in the renewable energy sector.

Project Details and Benefits

The $850 million Blind Creek project is projected to power approximately 120,000 homes, showcasing the scalability and potential of such innovative energy solutions. By strategically storing solar energy and dispatching it during peak demand periods, the project aims to maximise returns for investors while delivering valuable electricity to the market.

Construction of the Blind Creek facility is scheduled to commence within the next year, with a strong focus on grid modelling and technical partnerships to ensure seamless integration and operation.

Community Roots and Sustainability

The Blind Creek project, originally initiated by a group of local farmers and renewable energy experts, embodies a harmonious blend of solar and battery technology with traditional sheep production. The project’s unique approach allows for sustainable co-existence with rotational grass-fed lamb production, showcasing a holistic approach to energy and agriculture.
