Project overview

A live data-centre development in Western Sydney requires new high-voltage supply infrastructure and a staged migration from its existing electrical connection. The exact campus and client are withheld by agreement.

What Flomar self-performs

  • Construction of parallel 33kV feeder routes
  • Trenchless crossings beneath road and waterway constraints
  • Preliminary potholing and NDD service location along the routes
  • Segregated fibre network for utility monitoring and SCADA with redundant site links
  • Feeder integration at the network substation and the site's private switchboards
  • Staged 11kV-to-33kV migration and cutover with no outage to the live IT load, then decommissioning of the 11kV supply
  • Testing and commissioning - line impedance, HV injection and protection relay testing

Key quantities

  • Parallel 33kV feeders
  • Trenchless road and waterway crossings
  • Zero-interruption cutover of a live data-centre load
