Adelaide Airport has significantly boosted its commitment to clean energy by nearly tripling the capacity of its photovoltaic self-consumption system, thanks to a major rooftop solar installation completed by Iberdrola Australia.

The project involved the installation of over 3,800 solar panels across the rooftops of the airport’s domestic and international terminals. The new 2.3 MW system generates around 3,282 MWh of energy annually, increasing the airport’s total solar capacity to 3.5 MWp—enough to power approximately 1,000 households each year.

Adelaide Airport already sources 100% of its electricity from renewables, with energy supplied from on-site solar systems and Iberdrola’s Lake Bonney wind farms in South Australia. Prior to this upgrade, the airport operated two smaller solar systems—one atop a terminal and another on its multi-storey car park—with a combined output of 1.28 MW.

This development further strengthens Adelaide Airport’s position as a leader in sustainable aviation infrastructure. In December 2024, it became the first major airport in Australia to achieve carbon neutrality. As the main gateway to South Australia’s capital and the country’s fifth busiest airport, it serves over 8 million passengers annually.
