Supply and installation of complete earth grid system including buried earth grids, surface mounted earth grids, crimped connections, and connections to fence posts and gates.

The substation projects also included supplying and installing 15 x 20m deep earth electrodes at Wilton and 2 x 50m deep earth electrodes at Nepean.

Challenge : Installing earthing components in zone and transmission substations is specialised work. All steel reinforcement for concrete components is welded and requires continuity testing.

The projects were managed by Endeavour Energy for compliance with standards, and Abergeldie Complex Infrastructure management team and Earthing Solutions worked together to coordinate delivery.

Result: The project was finished on time and budget, with both substations completed in 2012.
