The Australian Renewable Energy Agency (ARENA) today welcomes the announcement by the Minister for Climate Change and Energy, the Hon Chris Bowen MP of the appointment of Marianna O’Gorman to the ARENA Board for a two year term. ARENA has also welcomed the reappointment of Stephen McIntosh for an additional two year term.

A non executive director at Australia’s second largest electricity generator, Queensland’s Stanwell Corporation, Marianna brings with her an extensive background in corporate governance.

ARENA’s Board has overall responsibility for the operations of the Agency. It is a skills-based decision making body, responsible for recommending the Agency’s annual general funding strategy to the Minister, setting investment priorities, overseeing the running of the organisation and approving project funding.

ARENA CEO Darren Miller welcomed Marianna O’Gorman to the Board, saying that her long track record and energy sector expertise are what ARENA needs to guide the agency as the energy transition gathers pace.

“Marianna is someone who knows ARENA well, having advised the Australian Government on our establishment more than 10 years ago. She brings with her a wealth of experience in the energy and climate space and I look forward to her joining us in this important work.

Stephen McIntosh has proven to be an invaluable asset to ARENA’s governance, having served two years with us already. His long career driving innovation in the resources sector offers us a wealth of expertise in our increasing work on industrial decarbonisation.”

Mr Miller also thanked outgoing board member Ms Stephanie Unwin, CEO of Horizon Power, who has served on the Board since 2018.

“I would like to thank Stephanie Unwin for her contribution to ARENA during a period of positive change and growth. Stephanie’s considerable experience within the renewable energy space has helped us in funding the right projects to ensure we deliver maximum impact on our path towards net zero,” Mr Miller said.

“I wish Stephanie all the best in her future endeavours and look forward to working with her in her capacity as CEO of Horizon Power.”
