Flow Power has secured a foundational offtake agreement with Octopus Australia for one of the largest hybrid renewable developments in New South Wales, the Blind Creek Solar Farm and Battery project.

The agreement follows financial close on the $900 million project in Bungendore, which will combine a 300 MW (megawatt) solar farm with a 243 MW / 486 megawatt-hours battery energy storage system. The hybrid design is intended to support greater volumes of renewable generation while enabling stored energy to be dispatched during evening peak demand periods.

Flow Power’s role as an anchor offtaker is expected to underpin the project’s commercial structure and demonstrate a firmed renewable energy model that integrates generation with storage. The approach reflects a broader market shift toward hybrid assets that can provide more consistent supply to the grid.

Byron Serjeantson, Chief Operating Officer and Chief Financial Officer at Flow Power, explained that the partnership shows alignment between the two organisations on the role of technology in supporting a more flexible energy system.

“Blind Creek represents the next generation of renewable energy projects, combining smart technology, firmer supply for customers, and regenerative agriculture,” he said.

“We’re proud to be a foundational partner, helping bring this project to life.”

Sonia Teitel, Co-Managing-Director at Flow Power, explains more.

“From the outset, our teams have been aligned on building a cleaner energy future grounded in innovation and customer value,” she said.

“This project sets a new benchmark for firmed renewables in Australia.”

The project has been designed as an agri-solar development, allowing sheep grazing to continue across the site while maintaining agricultural productivity. Once operational, the utility-scale project is expected to generate enough electricity to power more than 120,000 homes and reduce emissions equivalent to removing around 200,000 cars from Australia’s roads annually.

A direct current coupled system will enable energy generated by the solar array to flow directly into the battery, reducing conversion losses and improving overall system efficiency. This configuration is being adopted across Australia’s large-scale projects to maximise grid support during periods of high demand.

Construction on the Blind Creek Solar Farm and Battery project continues, with up to 300 jobs expected to be generated. GRS has been appointed as the project’s EPC (engineering, procurement and construction) contractor, with Wärtsilä Energy Storage supplying the battery system.

The Blind Creek project adds to Flow Power’s growing portfolio of long-term renewable energy partnerships, as retailers and developers continue to explore integrated solar and storage solutions to deliver dispatchable clean energy to Australian customers.
