Czech-based investment group Sev.en Global Investments, which owns half of Callide Power Station through its subsidiary IG Power, has filed proceedings against its joint venture partner CS Energy in the Federal Court of Australia.
IGPC has filed a statement of claim in the Federal Court of Australia concerning the actions of CS Energy as the state-owned operator of Callide C Power Station in Queensland.

These concerns include the explosion of the C4 generator in 2021, the collapse of the C3 cooling towers in 2022, and the explosion of the C3 boiler in 2025.
Between the two generation units at Callide C, more than 1,700 days of generation capacity has been lost in the past five years.
IGPC’s claim seeks to hold CS Energy and Callide Energy Pty Ltd (CEPL) accountable for the management of Callide C Power Station and its representations to the joint venture. IGPC is looking to recover losses in excess of $1 billion.
“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,” the company said in a statement.
Sev.en GI country manager Mark Sykes said, “Sev.en Global Investments has been a long-term 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 said it had also provided financial backing to the administration process since early 2024.
