AEMC Chairman John Pierce has welcomed the appointment of a new Commissioner to the AEMC.

The COAG Energy Council announced today that Ms Merryn York will join the Australian Energy Market Commission in late August, following the retirement of Commissioner Brian Spalding in April 2019. The appointment returns the total number of AEMC Commissioners to five.

Ms York has served as Powerlink’s Chief Executive since 2011 and was a member of the Reliability Panel from December 2012 to December 2015. Before joining Powerlink in 1995 she worked for the Queensland Electricity Commission.



“In addition to Merryn’s qualifications in electrical engineering and wealth of experience in system planning and operations, her familiarity with the AEMC and its processes should result in a seamless transition,” said AEMC Chairman John Pierce.

“Merryn brings to the role a consumer focus and firsthand understanding of the market participant’s experience in the transforming energy sector, which will complement the broad skillsets of her Commission colleagues.”

Commenting on her appointment, Ms York said that she is looking forward to her new role as a Commissioner at the Australian Energy Market Commission and involvement in the challenges of the rapidly changing energy sector.

Ms York’s five year term commences on 25 August 2019.

“On behalf of the current Commissioners, our Chief Executive Anne Pearson and the AEMC’s staff I would like to congratulate Merryn on her appointment and this new chapter in her career.”
