Chair and members

31 August 2017

The Clean Energy Regulator is the independent statutory authority, governed by the Regulator, a decision-making body consisting of a Chair and other Members. The Regulator is responsible for determining the agency's strategic objectives and policies which underpin its operation and performance to ensure it functions effectively.

Members of the Regulator are appointed by the responsible minister under the Clean Energy Regulator Act 2011, and are required to have substantial experience or knowledge in fields relevant to the Clean Energy Regulator. The Chair holds office on a full-time basis. All other Members hold office on a part-time basis.

At 1 April 2017, the Regulator had five Members, including the Chair. Ms Anne T Brown and Ms Virginia Malley were appointed on 4 June 2012, Mr Michael D'Ascenzo was appointed on 22 March 2013 and Dr Peter Davis was appointed on 18 January 2016. The Minister for Environment and Energy appointed Mr David Parker as Chair of the Clean Energy Regulator on 3 July 2017. ​

In addition to their collective responsibilities, Members of the Regulator each apply their expertise to a specific area of focus. This adds depth to the Regulator's appreciation of its operating environment and enables agency officers to draw directly on Members' knowledge and experience. Members provide an update on their area of focus at each Regulator meeting.
