Callide C Power Station: Commencement of Federal Court Proceedings against CS Energy Limited and Callide Energy Pty Ltd
Press Release (Sydney, Australia — June 22. 2026)
Concerned by the actions of CS Energy as the operator of Callide C, Sev.en Global Investments (Sev.en GI), through its subsidiary IG Power (Callide) Limited, has commenced legal proceedings in the Federal Court of Australia against its joint venture partner Callide Energy Pty Ltd (CEPL) and CS Energy.
CEPL is 100 per cent owned by CS Energy.
IGPC has filed a statement of claim in the Federal Court of Australia, concerning the explosion of the C4 generator, the collapse of the C3 cooling towers and the explosion of the C3 boiler. Between the two generation units at Callide C, over 1,700 days of generation capacity has been lost in the last 5 years alone.
The claim seeks to hold CS Energy and CEPL accountable for CS Energy’s management of the Callide C Power Station and its representations to the joint venture.
IGPC seeks to recover losses caused by this management, which presently exceed 1 billion AUD.
IGPC’s decision to commence these proceedings follows an extended period of dialogue with CS Energy and CEPL, during which Sev.en GI and IGPC have pursued alternatives to litigation. Regrettably, these efforts have been unsuccessful.
Sev.en GI’s Country Manager, Mark Sykes said: “Sev.en Global Investments has been a longterm investor in Australian energy infrastructure and we have commenced these proceedings only after an extended period of engagement and careful consideration.”
Sev.en GI has been a key supporter of the rebuild efforts since the initial serious incident in 2021.
Sev.en GI has also provided financial backing to the administration process since early 2024.
In May 2025 Sev.en GI announced the acquisition and recapitalisation of the 50% stake in the Callide C Power Station.
Within the joint venture structure, operational control and responsibility for the operation and maintenance of the Callide C Power Station rest with CS Energy.
IGPC is now pursuing its rights to recover the extensive damage it has suffered.
