What is Ariba?

Ariba is an online network that supports collaboration between buyers and suppliers, including allowing suppliers to respond to sourcing events, receive orders and send invoices, and manage their supplier information. See ariba.com and details below for further information. 

All suppliers will need to have, at a minimum, a Standard (Light) account with SAP Ariba in order to interact with Western Power for the below activities (excluding supplier requests, which do not require an account).

Supplier request

To register your interest in becoming a Western Power Supplier use the supplier request form.

Once processed, you may be sent a supplier registration questionnaire asking for additional information. Please note that that this does not guarantee that an opportunity to formally quote on or receive work will eventuate.

The onboarding process consists of multiple steps as shown below. Suppliers being invited to tender are required to respond to a “Registration Questionnaire”, and existing or new suppliers will be required to fill out all questionnaires from registration onwards. You can then maintain these details in Ariba going forward, including loading valid insurances on an annual basis.

See our Supplier Onboarding Process and Supplier FAQs for further information and support. 

Tender events

Western Power uses Ariba for all tendering activities. If you're invited to participate in a sourcing event, you will receive an invitation email containing a hyperlink to Ariba. Once you have logged into Ariba, you will be guided through the process of submitting a response.

To notify us of your interest in upcoming events, please visit our Tenders and registrations of interest page. Please note our tenders are by invitation only and registering your interest does not guarantee you will be invited to an event or awarded any work.

For support in responding to a tender event, see our Responding to events in Ariba guide.

Supplier accreditation (onboarding)

'Supplier onboarding' is the process of accrediting suppliers to trade with Western Power through our procurement systems. Western Power utilises the Ariba system to accredit/onboard suppliers, where suppliers can submit and manage information such as insurances, address and banking details.
