OUR DISCLOSURE
Performance at a glance
Operating context
Powerlink’s operating environment is shaped by a more diverse generation mix, increasing transmission network operating complexity, and a higher overall cost environment.
It has never been more important or challenging for a network business to get the balance right between investment to ensure reliability and minimising price impacts for its customers. This requires strong engagement with our customers, to underpin well‑informed decisions in a timely way.
Business Drivers
Delivering for Queenslanders
Queenslanders expect a safe, reliable and sustainable transmission network at prices that are reasonable and predictable. Powerlink supports this by enabling the connection of new generation and storage, adopting new approaches and technologies, and making efficient investment decisions.
Supply chain challenges
Since 2021, higher equipment costs and global supply chain disruptions have increased delivery pressures across the sector. Powerlink continues to actively manage procurement and delivery risks, including through early engagement with suppliers, sequencing delivery, and applying established project delivery practices that help reduce costs, timeframes and impacts.
Increasing system complexity
Queensland’s power system is becoming more complex to operate as demand and generation patterns change, assets age, and cyber risks increase. This reinforces the need for timely planning and investment, appropriate adoption of new technologies, retaining a capable workforce, and strong community trust.
