Merriwa Substation transformer energised

Tyree has recently designed, supplied, and installed a 4MVA 33/11kV Power Transformer for Ausgrid’s Merriwa Substation which was fully commissioned and energised in the first week of March 2022.

Working very closely with the Ausgrid team, Tyree designed and manufactured a transformer which fitted neatly within the exiting site footprint of this brownfield substation. Tyree’s Field Service Team arranged delivery, unloading and positioning of the transformer into the physically constrained substation. The works required a significant outage due to the nature of the site, however Tyree’s delivery timing was all to plan which avoided any extended power outages for the township of Merriwa.

Tyree’s General Manager for Field Services Will Vanleerdam related to the Tyree team our customer’s congratulations “for completing the site project as planned and excellent cooperation from both companies to overcome the numerous challenges and interruptions created by COVID and inclement weather during the delivery, installation, testing and final commissioning”.
