Board appointments for Australian Renewable Energy Agency

The Albanese Government today announces the appointment of Marianna O'Gorman to the Australian Renewable Energy Agency (ARENA) board and confirms the re-appointment of Stephen McIntosh for another term.

Ms O'Gorman brings a wealth of corporate governance and government advisory experience to ARENA, covering climate, energy, technology innovation and sustainable finance.

She started her career working on climate change at the World Bank, and worked on ARENA’s establishment.

Marianna has been appointed for a two-year term, replacing Stephanie Unwin who has been a highly valued board member since 2018, and is nearing the end of the maximum term.

The tenure of Mr McIntosh, a resources sector veteran of 36 years with invaluable experience as Rio Tinto’s head of innovation, has been extended a further two years after he joined the board in 2021.

ARENA is a proud Australian legacy, and since its creation in 2012 – it has provided $2.15 billion in grant funding to unlock almost $9.41 billion of investment in Australia’s renewable energy industry.

Minister for Climate Change and Energy Chris Bowen welcomed Ms O'Gorman’s appointment and thanked Ms Unwin for her outstanding service.

“ARENA’s work is central to driving innovation for cleaner, cheaper energy,” Minister Bowen said.

“Marianna comes extremely qualified to add to ARENA’s great legacy and will be an asset in guiding ARENA’s continued investment and support for innovation in the clean energy sector. 

“I would also like to thank Stephanie for her valuable contributions to ARENA and welcome Stephen’s re-appointment."
