Zen Energy’s statement attributed the administration to the retail division’s inability to withstand sustained wholesale market pressure.

“The retail business has continued to be impacted by continued wholesale electricity volatility, that has undermined the viability of a going concern sale, despite significant support from a range of stakeholders, including the South Australia (SA) government, SA Power Networks and various regulators,” the company said.

The administration follows a winding-up application filed by SA Power Networks on 26 June 2026, recorded by the Australian Securities and Investments Commission (ASIC) as a notice of application for a winding-up order against Zen Energy Retail Pty Ltd (ACN 615 751 052).

That application is scheduled to be heard at the South Australian Federal Court on 5 August 2026. Separately, the Australian Energy Regulator (AER) announced on 3 July 2026 conditional approval for Zen Energy Retail to transfer its electricity retail authorisation to Zen Energy Retail Holdings, a transfer that SA Power Networks had opposed.

Zen Energy had held an Across Government Electricity Retail Agreement with the South Australian government to supply 100% renewable energy to government operations until 2035, a contract estimated to be worth AU$1.53 billion (US$1.06 billion).
