Response to latest media reports about 27 November cyber security incident

08 Dec 2021

CS Energy’s power stations have continued to generate and dispatch electricity into the National Electricity Market since the ransomware incident on our corporate ICT network on 27 November.

CEO Andrew Bills said CS Energy’s ICT systems and safeguards had layers of separation and protection, which enabled it to contain and protect its critical infrastructure to ensure continuity of power to Queenslanders.

“Upon becoming aware of the incident, we quickly took further assertive action to physically separate the two environments,” Mr Bills said.

Mr Bills said there was currently no indication that the cyber incident was a state-based attack.

“We continue to progressively restore our systems and are working closely with cyber security experts and relevant state and federal agencies.”

Australia’s National Electricity Market is designed to ensure there is enough power generation and network capacity to securely meet customer demand, even in the event of unexpected outages of transmission lines and generators.
