Iberdrola has completed the installation of over 600,000 solar panels at the Broadsound plant in Queensland, combining 376 MW of solar with 180 MW of battery storage.
Iberdrola Australia has completed the installation of more than 600,000 solar panels at the Broadsound plant in Queensland, Australia. According to the company, the project combines 376 MW of solar capacity with a 180 MW battery storage system to provide stable renewable electricity. Once operational, the plant is expected to generate enough power for around 145,000 homes. This achievement comes amid a dynamic period for solar, as highlighted by J&V Energy’s acquisition of a 187 MW solar portfolio in Taiwan.
The Broadsound site uses solar tracker technology to optimize sunlight capture and boost renewable output. Pairing the solar array with a 180 MW battery storage unit is designed to smooth out the intermittency of photovoltaic generation. Iberdrola notes that this hybrid setup will enhance the reliability of power delivered to the local grid.
Combining solar and storage is becoming a defining feature of large-scale renewable projects. It helps offset production swings due to weather conditions and better manage peak demand. Iberdrola’s choice of this architecture reflects an industry-wide trend.
Completing the installation phase at Broadsound strengthens Iberdrola’s foothold in the Australian market. The group already has 2,500 MW of installed capacity in the country, spanning wind, solar and storage projects. This scale makes it a key player in Australia’s energy transition.
As part of its international expansion, Iberdrola plans to invest more than €1 billion in the country by 2029. The company intends to use these funds to develop new renewable assets and storage solutions. Iberdrola aims to strengthen its presence in a fast-growing market.
The Broadsound plant exemplifies the acceleration of clean energy deployment in Australia, where solar resources are abundant. Similar initiatives are emerging globally, such as the 850 MW solar PPA partnership between DESRI and Meta, which has exceeded 2.5 GW.
This project also supports Queensland’s climate goals, as the state banks on renewables for energy security. With this milestone, Iberdrola marks a key step in its green investment program.
