Becoming a supplier

We value our supplier relationships

As a Government Trading Enterprise, Horizon Power operates within commercial principles, and consistently aims to maximise long term value. We are committed to conducting our procurement activities ethically, honestly and fairly whilst achieving value for money and providing quality services.

Our regional operations are responsible for many of Horizon Power's regional procurement decisions. Our purchasing processes consider local industry capabilities and give back to the communities we serve however we can, including supporting regionally-based businesses.

We invite suppliers to respond to open tenders through Tenders WA. We also recommend that you keep your website, promotional materials and Supply Nation profile (for Aboriginal and Torres Strait Islander business) up to date at all times. This helps us to identify potential suppliers in circumstances where we can direct source, or invite a restricted number of suppliers to respond to a quote.

Horizon Power does not require pre-qualification of suppliers, however all suppliers that have negotiated an active contract (including a purchase order) will be required to complete the process to become an accredited supplier.

What and how we buy

Through a range of procurement processes we buy: construction, consultancy, corporate services, fleet, logistics, maintenance services (electricity related and non-electrical), major equipment, minor equipment and consumables, property management, SCADA and retail services, technology and temporary labour.

Our major purchases are usually subject to an open tender process. We frequently invite expressions of interest and requests for quotation for smaller pieces of work, primarily in the construction, technology and maintenance spaces.

Horizon Power sourcing processes are streamlined according to the risk profile associated with the requirement.  

As a general guide, we purchase through the following procurement processes:

  • Direct sourcing (restricted process)
  • Requests for Quotation (RFQ) (open or restricted process)
  • Requests for Tender (RFT) (open process)
  • Expressions of Interest (EOI) (to understand how a good or service can be provided)

We recommend that your business:

  • Has an up to date website
  • Maintains current contact details and is responsive to enquiries
  • Registers with Tenders WA for alerts on relevant tenders
  • Registers with relevant industry portals such as Supply Nation
  • Follow us on LinkedIn and Twitter where we often advertise open procurements
  • Checks local newspapers for opportunities to supply

These recommendations apply to all levels of procurement processes.
