Coonawarra Energy Project
Project overview
Coonawarra is in the heart of the Limestone Coast of South Australia.
The celebrated wine region known for its vivid red soil is now home to an innovative solar and battery project built, owned and operated by Flow Power.
About the project
Coonawarra Energy Project produces 6.01 MW of solar, paired with 5 MW/15 MWh of battery storage.
The 15 ha project site features approximately 10,000 solar PV modules, on a self-powered single axis tracking system supported by more than 1,200 piles.
The ancillary infrastructure and equipment are designed to be operated and controlled remotely to connect to SA Power Networks.
Innovative anti-hail technology
Coonawarra Energy Project is the first of Flow Power’s renewable projects to feature innovative anti-hail solar panels from Canadian Solar.
The extreme weather resistant modules are part of Canadian Solar’s CS6.2 series which use 182mm pro cells.
The anti-hail variant of the module is designed for sites prone to hailstorms and can help counteract rising insurance premiums and reduce operation and maintenance costs.
About the land
The South East Aboriginal Focus Group are the Traditional Custodians of South East of South Australia.
Flow Power worked with Burrandies Aboriginal Corporation to plant vegetation on site. Over 700 plants were selected as a mix of native small trees and shrubs suited to the local region, with a mature height of between 5–8 m. This allows them to provide effective screening to the site while avoiding shading of the solar panels.
The town of Coonawarra was chosen for this type of energy project due to its proximity to existing grid infrastructure for connection, land availability and ample sunshine.
Coonawarra Energy Project generates and stores clean energy for South Australia’s grid, helping reduce carbon emissions and support the integration of renewables.
The Project supports more affordable energy outcomes for consumers by adding new renewable supply in high price peaks when it’s needed most, increasing competition in the market and reducing the influence of large generators. This helps to keep prices lower.
With its integrated battery system, the Project can rapidly deliver energy during peak demand or outages, strengthening reliability across the network. Installation of utility-scale batteries can also postpone or replace costly power line upgrades that would ultimately be paid for by electricity customers.
Flow Power is committed to engaging local workers, businesses, and contractors wherever possible, ensuring the project delivers meaningful benefits to the Coonawarra community.
Community benefits & initiatives
Flow Power is proud to support Penola Football Club’s restoration initiative, as a focal point and important shared space for the community in the region.
Flow Power is working with Coonawarra Air Strip to construct toilet facilities onsite for students and visitors. The initiative will include open access to the public and clear signage along bike touring paths.
We are excited to launch an electricity offer for the residents of Coonawarra and Penola. The bespoke offer will be available to commercial and industrial businesses, SMEs and residential customers.
Across our project sites, we work to promote the use of beneficial agrivoltaics. At Coonawarra, the landowner’s sheep will graze onsite, helping manage vegetation while the panels provide vital shade for the flock.
FAQs
Flow Power has consulted with the local Fire Service (Region 5) to ensure our fire safety measures are suitable for the local area. This included a site familiarisation visit with the local bridge.
For onsite water supply, the project hosts a 72,000 L water tank. We also plan to run sheep across our site to ensure grasses are naturally kept very low and to help minimise fuel load during fire danger season.
A team of technicians regularly inspects and cleans the panels, monitors battery health, and ensures everything runs smoothly.
Batteries store electricity, so solar farms like Coonawarra can turn variable output into reliable power.
By charging with solar during the day when demand is low, and discharging to the grid during evening peaks, when increased demand typically drives high prices, batteries can help stabilise supply and put downward pressure on electricity prices.
Approximately 40 jobs were created during construction. There will be ongoing longer-term maintenance contracts, preferencing local workers and businesses.
