Snowy Hydro announces the appointment of Mr Dennis Barnes as Chief Executive Officer and Managing Director as of 1 February 2023.

Chairman David Knox said the Board was delighted to appoint Mr Barnes and is confident that he will continue strengthening Snowy Hydro’s position as a leading integrated energy generator and retailer.

“We are thrilled to appoint someone of Dennis’ calibre and extensive energy sector experience to lead Snowy Hydro into the future,” says Snowy Hydro Chairman David Knox.

Snowy Hydro is Australia’s largest renewable energy project and underpins Australia’s transition to a low carbon emissions future. It will provide on-demand energy and large storage for several generations to come. 

“Dennis has over three decades’ experience in the energy sector, with a focus on renewables and retail. His appointment brings a wealth of strategic knowledge and proven capability in delivering strong performance across large energy businesses at an exciting time for Snowy Hydro.”

Mr Barnes was most recently CEO of ASX/NZX-listed Contact Energy, guiding the company through a period of significant change, including the separation from Australian majority shareholder Origin Energy and the completion of a NZ$2billion investment programme encompassing renewable generation and enterprise-wide systems.

Before this, Mr Barnes also held several senior executive roles at Origin Energy, including as General Manager, Energy Risk Management and General Manager, Generation Operations; and he currently serves as a non-executive director of Tilt Renewables and Mercury NZ.

“I am excited about working with the excellent team at Snowy Hydro, a truly iconic Australian business, at a difficult and important time for our entire sector. I am also particularly looking forward to building strong connections with our stakeholders and the communities we serve and operate in as we address the major issues our sector must focus on,” says Snow Hydro Chief Executive Officer and Director Dennis Barnes.

The appointment follows a comprehensive local and international executive search process. Roger Whitby, who has been Acting Chief Executive Officer since August, will resume his role as Chief Operating Officer.

“I would like to thank Roger for his leadership, commitment and steady guidance during this period of transition for the company,” says Snowy Hydro Chairman David Knox.
