Transacting with Western Power

Western Power utilises the SAP Ariba Network for transacting with suppliers at all stages of the procurement lifecycle, including

  • tendering
  • contract management
  • catalogue management
  • issuing purchase orders
  • receipt and payment of invoices.

The benefits of using the SAP Ariba Network (eProcurement) include:

  • streamlined purchasing processes that deliver shorter turn-around times in obtaining required goods and services
  • increased transparency in transactions to track the progress of orders
  • improved invoicing capabilities to facilitate faster payments to suppliers.

The benefits allow us to deliver safe, reliable and efficient services to all customers. Our suppliers play an important role in helping us achieve our objectives.

Suppliers who are new or transitioning to transacting with Western Power via Ariba, are required to subscribe to the Ariba system.

Setting up an Ariba Account

All suppliers not holding an Ariba account are required to register for an Ariba Network account in order to transact with Western Power. To help in choosing the best account option, supporting information is available under the Ariba supplier guides on this page.

Once your account option has been selected:

Existing suppliers: Please provide your Ariba Network Identification (ANID) and an email address registered to your Ariba account to which orders will be sent electronically to ariba.specialist@westernpower.com.au.

New Suppliers: Please register your interest via the Becoming a Supplier page and Inform Western Power by following the instructions in the Supplier Accreditation Pack when requested
