We are seeking registrations of interest from suitably qualified and experienced companies capable of carrying out the development, supply & installation of modular substations.

We are in the process of evaluating alternative options to the preferred Transformer replacement solution. The alternative option being considered for this ROI is the concept and practicality of Modular Substations.

This equipment is expected to replace and upgrade a number of 10MVA, 66/22 kV and 132/22 kV power transformers at existing Western Power substations over the short to long term. The initial installation will occur at the Wagin zone substation.

For the purpose of this project, a Modular Substation is an integrated asset comprised of hybrid HV switchgear, a step down transformer and associated protection and control equipment. The substation is skid mounted and is preassembled for simplification of installation and to minimise on site works, testing, cost and construction lead time.

The Project Requirements

We are seeking registrations of interest for the following project requirements: 

Requirement A: Supply, Install & Commission, of a 10 MVA, 66/22kV modular substation

Requirement B: Supply, Install & Commission, of a 10 MVA, 132/(66)/22kV configurable modular substation

Requirement C:  Supply, Install & Commission, of a 10 MVA, 132/22kV modular substation

 Supply, Install & Commission includes:

  • Design, supply, installation and commissioning of complete modular substation to the required specifications.
  • The modular substation equipment is required to be pre-commissioned prior to delivery.
  • Installation of the modular substation is expected to be carried out by the Supplier. Future relocations will be carried out by Western Power.
  • Integration of the modular substation with Western Power equipment is expected to be carried out by Western Power personnel, with support from the Supplier for final commissioning.

To be considered, please register your interest by completing the supplier registration form by 25 January 2019.

Please ensure the following details are included in your registration:

  • Registration of interest for one or more of the Requirements A, B, C
  • Description of expertise in the design, supply, installation and commissioning of modular substations of this type.
  • Modular Substation Projects successfully completed.
  • Reason for Registration (please select ‘in response to an advertised bid’)
  • Title of the procurement event (please enter ‘Modular Substation Project')
