ZEN Energy enters administration after retail sale falters

Rob Smith and Jason Preston of McGrathNicol were appointed voluntary administrators of the residual ZEN Energy group on 2 July 2026, following a restructuring and recapitalisation process that had been under way for several months.

ZEN was founded by economist Ross Garnaut and developed a business supplying renewable electricity to major corporate and government customers through long-term contracts supported by wind, solar and battery projects. It had previously entered a long-term agreement to supply electricity to South Australian government operations.

The Adelaide-based company said it had completed the sale of its infrastructure asset business, which held a portfolio of renewable generation and battery storage interests, but had been unable to secure a viable outcome for its electricity retail operations.

ZEN attributed the administration to continuing volatility in wholesale electricity markets, which increased the cost and risk of meeting fixed-price supply obligations to commercial and government customers. The company said those pressures undermined a proposed going-concern sale despite support from the South Australian government, SA Power Networks and regulators.

McGrathNicol is undertaking an urgent assessment of the group and engaging with employees, customers and other stakeholders to determine the future of its remaining operations, retail licences and market registrations.

The appointment came shortly after regulatory decisions cleared important elements of a proposed transaction involving global commodities trader Gunvor. The Australian Energy Regulator on 30 June conditionally approved the transfer of ZEN Energy Retail Pty Ltd’s electricity retailer authorisation to related company ZEN Energy Retail Holdings Pty Ltd. However, this did not result in a completed going-concern sale before the administrators were appointed. The AER’s approval was subject to financial conditions intended to ensure the proposed licence holder had sufficient resources to meet its obligations as an electricity retailer. The transfer application had been lodged in May as part of the broader restructuring.

ZEN ceased retailing electricity following the appointment. South Australian government sites and essential services previously supplied under the state’s Across Government Energy Retail Agreement were transferred to AGL under retailer-of-last-resort arrangements, with the government saying electricity supply had not been interrupted. The government has begun a procurement process for a replacement supplier.

The administration also followed a winding-up application filed against ZEN Energy Retail Pty Ltd by SA Power Networks on 26 June. The application had been listed for hearing in the Federal Court in August.
