General supplier
Ariba (SAP Business Network) connects buyers and suppliers. We use it for sourcing events, ordering, invoicing and supplier information. See Using Ariba as a Western Power supplier.
Our purchase orders include general terms and conditions. If an order is issued under an existing contract, the terms of that contract applies and the purchase order will reference the contract number. Where there’s no contract, our purchase order terms and conditions apply.
See our Sustainable procurementpage.
Becoming a supplier
See Working with Western Power and Tenders and registrations of interest. If your query relates to an open event, contact the Sourcing Specialist listed on the tender.
Complete the Supplier Introduction Form, ensuring all mandatory fields are completed. Submitting the form doesn’t guarantee contact or work; we’ll keep your details for relevant opportunities.
Tenders and registration of interest
We balance financial and non-financial factors such as quality, capability, fitness for purpose, total cost of ownership, risk and benefits to Western Australians; not just purchase price.
See Responding to events in Ariba. For event content questions, use the messaging feature in the event.
Registering interest helps us understand your capabilities, but doesn’t guarantee an invitation or work. Tenders are by invitation only.
No. We seek the best value for money.
Western Power uses 'preferred vendor arrangement' for many contracts. Preferred vendor arrangements are established following a tender process to pre-qualify suppliers for specific goods or services. Being a preferred vendor does not guarantee any work, however it does ensure that the ordering process under the arrangement is more streamlined and does not require suppliers to resubmit their standard safety, environment and quality information, or departures from the commercial documentation.
Supplier accreditation
It’s how we set you up to trade with us through SAP Ariba. We complete standard checks to make sure you can deliver safely and affordably. Visit the Using Ariba as a Western Power supplier page for more information.
Email us with details, including insurance certificate name.
Existing Western Power suppliers will be asked to resubmit their accreditation details in an online format as a once-off activity. Expiring documents such as insurances can then be maintained in an electronic format via Ariba, streamlining the process of updating these important documents with Western Power.
