Another coal generator CEO heads for the door as EnergyAustralia's Tanna retires
29 April 2021 One of Australia’s big three energy utilities, EnergyAustralia, says it appointed chief customer officer Mark Collette as its new managing director, effective July 1, following the decision by Catherine Tanna to retire after seven years at the helm. It is third departure of a CEO from a major coal generator in little more than a week, following the surprising exit of Brett Redman from AGL in the middle of its demerger plans, and the sudden exit of Ricard van Breda from Stanwell Corp in Queensland after he talked of a possible early closure of some of its coal units.
