220kV Buronga Switching Station Synchronous Condensers Installation

CPP was single-sourced by TransGrid to deliver an accelerated program for the combination of the works on the Finley Solar Farm Connection Project and Darlington Point Solar Farm Connection Project. This was a D&C contract to install one ABB type AMS 1400LH 4L BS brushless synchronous condenser for Finley Solar Farm Project and two ABB type AMS 1250LK 4A BST brushless synchronous condenser for Darlington Point Solar Farm Project, both to be installed at Buronga Switching Station in western New South Wales.
