GE Vernova announced it has secured a contract from Powerlink, Queensland’s state-owned transmission utility, to supply essential equipment for their upcoming Capital Work program.
Under this agreement, GE Vernova will deliver 69 Dead Tank Circuit Breakers (DTCBs) rated 245kV and above, supporting Queensland’s renewable energy targets and enhancing power infrastructure resilience.
Scheduled for delivery between August 2025 and March 2026, the DTCBs will be manufactured by GE Vernova’s Grid Solutions business at its factory in Suzhou, China. This global supply chain approach enables timely and efficient delivery to meet the needs of complex, large-scale projects.
What is DTCB?
Dead Tank Circuit Breakers (DTCBs) play a crucial role in maintaining stable power transmission by protecting the grid from electrical faults, ensuring continuity of energy flow and minimizing disruptions.
They are like powerful “off switches” for the grid, automatically isolating sections of the network during faults or overloads to keep electricity flowing smoothly and protect the system from potential damage. These devices are especially important for energy transition efforts, as they enable the reliable integration of renewable energy sources, which can be challenging without stable and resilient transmission infrastructure. Without equipment like DTCBs, reliably evacuating renewable energy from generation sites to end-users would be difficult, as fluctuations could disrupt the grid.
Trusted legacy
GE Vernova’s Dead Tank Circuit Breaker technology is recognized for its reliability and scalability, making it a strong choice for projects that require resilient and high-performance transmission solutions. With approximately 100,000 units installed globally, GE Vernova’s Grid Solutions business has built a trusted legacy of delivering advanced circuit breaker solutions that support renewable energy integration and energy security efforts worldwide.
According to Yeow Keong Lim, Asia Pacific Region Leader for GE Vernova’s Power Transmission business, “We remain dedicated to supporting Australia’s transition to a sustainable energy future through advanced technology that reinforces grid resilience and reliability.”
Queensland’s RE targets
Powerlink is responsible for building and maintaining Queensland’s high-voltage transmission network and connecting renewable energy sources across the State. Their work is central to Queensland’s commitment to renewable energy, with targets of 70 per cent by 2032 and 80 per cent by 2035, as it facilitates the integration of renewable energy into the grid to support economic growth and sustainability.
