Zen Energy entered administration after failing to manage significant downside risk across its long-term electricity contracts.
The collapse followed a drop in renewable certificate prices from $10 by late 2025.
"Zen’s business model exposed the group to significant market risk through long-term and substantial positions in the energy market, with market conditions moving against these positions," said McGrathNicol Administrator Robert Smith.
The Adelaide-based retailer recorded consecutive losses and was heading towards a $322 million annual deficit prior to the collapse.
McGrathNicol stated that secured lenders owed $415 million will receive nothing.
The renewable retailer had previously split its operations into separate retail and infrastructure divisions before the infrastructure unit was sold off.
Prior to entering administration, the business attempted an emergency sale process, but discussions with potential buyers were ultimately terminated.
