This project was awarded to TGOOD Australia by AGL and installed at a site in South Australia in 2025. It included 11 electrical substation kiosks made by TGOOD and each of them had unique configurations. All 11 kiosks are interconnected to cater to load flow in the surrounding area.
The Koompartu Microgrid will supply electricity to an existing almond orchard located on Cooltong Station in Monash, with its centre approximately 10 km north-west of Berri, in the Riverland region of South Australia. The farm will eventually be connected at 11 kV to the SA Power Networks (SAPN) distribution network. As the SAPN network does not have sufficient capacity to supply the maximum demand of the site, the supply will be augmented by generation from an on-site solar farm.
TGOOD Australia’s 11 substation kiosks each contain ring main units (RMUs), transformers and LV distribution boards. The RMUs are TGOOD’s 11kV TGS-12. The transformers are 500kVA and 1600kVA with different impedance levels. The LV boards have a unique design for each substation kiosk.
Our MV kiosk substations are modular units designed to protect the switchgear inside from the harsh outdoor elements of remote Australian electrical sites. They feature a compact, efficient design, arc-resistant electrical components engineered in Germany and internal climate control systems for the integrated TGOOD switchgear.
TGOOD Australia successfully managed a number of challenges with this project, including:
- Delivering the project in a record short timeline
- Dealing with a slightly unusual (VT) panel solution
- Taking care of late changes in specifications
- LV board design with the current rating of 2500 A at 50 °C
TGOOD Australia’s engineering work started in February 2025, including working out how to implement the necessary VT panel solution in the factory. We encountered challenges in design finalisation of the transformer specifications and LV board, but managed to solve every problem in limited time.
We received good support from AGL with approval of drawings and feedback, so that we could align with the project schedule. When the late specification changes occurred there were many issues for us to manage with our factory, but in the end we were proud of their work, as well. We managed to do our factory acceptance testing (FAT) on time and received the substation kiosks at our Rocklea assembly facility in Australia.
We completed a FAT on the LV boards at the third-party manufacturer’s site to ensure we would get the right product in the desired timeline. We received excellent support from the LV manufacturer to deliver the panels to us on time.
Once all the equipment was in our assembly facility in Rocklea, final integration work began. This phase of the project was not easy, especially the final delivery. Our team doesn’t shy away from a challenge, so we relied on the excellent teamwork at Rocklea and the continuous close watch on the schedule by our cross functional managers and engineers. In partnership with our colleagues at TGOOD Global, our parent company, TGOOD Australia delivered all of the kiosks on time.
