Receipt of first 5.3.4A&B letters

January 2024

Australian renewable energy developer, ACE Power, is pleased to kick off 2024 with the news that the 5.3.4A&B approval letters have been received from AEMO for our 103MW Kerang BESS and 200MW Yabulu BESS projects. Both projects will be connected into the transmission network directly via existing network substations at their respective locations.

Senior Development Manager & BESS Lead, Shane Humphreys, said ACE Power was delighted with the outcome.

“We are very proud as ACE Power to have achieved our first two 5.3.4A&B approvals from AEMO in close succession. These are among the earliest approvals nationwide for BESS to operate in grid forming mode from the date of commissioning. This outcome is the culmination of over 12 months work, and considerable engineering input from our respective consultants as we navigated an evolving landscape in respect of how grid forming inverter technology is assessed by AEMO and the NSPs.”

Both projects operating in grid forming mode will contribute positively to network stability on a 24/7 basis and this is expected to unlock further capacity for renewable connections in the surrounding area.

“With these approvals, the projects are now significantly de-risked, as we shift our focus towards moving the projects into construction by Q2 2024, and ultimately bringing forth the network and consumer benefits that come with the deployment of advanced BESS inverter capabilities”, Mr. Humphreys said.
