GE Vernova has secured a contract from Powerlink, Queensland’s state-owned transmission utility, to supply essential equipment for its upcoming capital work program.
Under the 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.

Powerlink is responsible for building and maintaining Queensland’s high-voltage
transmission network and connecting renewable energy sources across the state. Its work is central to Queensland’s commitment to renewable energy, with targets of 70% by 2032 and 80% by 2035, as it facilitates the integration of renewable energy into the grid to support economic growth and sustainability.
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 minimising 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.
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.

Powerlink CEO Paul Simshauser says, “Our commitment to reliable and efficient
energy transmission is furthered by partnering with GE Vernova to equip our network
with advanced grid technology.
“This contract will help ensure that Powerlink’s infrastructure can support the ambitious goals of Queensland’s renewable energy investors.”
