A legacy-critical transformer upgrade for the Snowy Scheme – delivered inside a confined hydro station with staged outages, alpine constraints, and zero room for error.

Tumut 2 Power Station plays a critical role within the Snowy Scheme – supplying renewable power through a high-head storage and generation system. Originally commissioned more than 60 years ago, the station required a major transformer and protection system upgrade to maintain operational integrity and meet current safety and grid standards.

PHE Group was engaged by Snowy Hydro under a lump sum contract to deliver the electrical scope. Works were undertaken in a live environment under compressed outage windows, within a confined transformer hall located in remote alpine terrain.

The delivery formed part of a broader program of upgrades across Snowy Hydro assets, reinforcing long-term trust in PHE's technical capability and adaptability in legacy hydro environments.

Project Scope

  • Removal of ageing transformer protection systems and associated cabling.
  • Installation of new transformer protection cubicles and current transformers.
  • Installation of 330kV cable protection systems within the live transformer hall.
  • Construction of cable ladder systems for physical separation and safety.
  • Isolation panel modifications and associated quality assurance testing.
  • Integration and termination of all new equipment and high-voltage conductors.
