Flow Power has secured development approval for a new solar and battery project in Monarto, South Australia, marking a significant step forward in supporting the state’s renewable energy future.
Located 70km southeast of Adelaide, the Monarto Energy Project will deliver clean energy and grid stability to the region and state. The approved site, one of four nearly identical projects planned for construction in the next 12 months, will feature a 5MW solar farm paired with up to 15MWh of battery storage.

Once operational, the project will supply renewable energy while supporting the local grid during periods of peak demand. The project will also provide essential Frequency Control Ancillary Services (FCAS), helping to stabilise grid frequency and strengthen the region’s energy resilience.
The Monarto Energy Project forms part of Flow Power’s broader strategy to deliver renewable energy to South Australian businesses. This initiative complements Flow Power’s existing renewable portfolio, including a 40MW, 10-year Power Purchase Agreement with Neoen’s Goyder South Stage 1 Wind Farm, a key part of the Goyder Renewables Zone near Burra.
By developing both wind and solar projects, Flow Power aims to contract more renewable energy to its South Australian business customers, meeting the growing demand for clean, reliable energy solutions.
“The Monarto Energy Project is situated in a great spot, with high annual irradiance, a strong network connection, and compatible land use,” Flow Power general manager energy projects Tom Harrison said.
“Designed as a solar farm with up to 15MWh of DC-coupled battery energy storage, Monarto will be able to reliably deliver firm renewable energy to the region long after the sun has set.
“The team and I are looking forward to working with SA Power Networks, and our local contractors, community members, and stakeholders to make this another successful Flow Power project.
“In addition to having a positive impact on the energy market and climate, we also look forward to delivering broader community benefits and environmental outcomes through this project.”

Monarto will be the fourth Flow Power project constructed in South Australia, and its fourth DC-coupled solar farm and BESS in the NEM.
The Monarto Energy Project, together with the three remaining sites (pending approvals) will scale up to 20MW of solar capacity and 60MWh of battery storage, enabling Flow Power to provide even greater renewable energy and grid support.
Construction of the four sites is expected to be completed by the end of 2025.
