FAQs

  • What is Regulated Asset Base (RAB)
  • What if I change my mind or want to cancel my application?

Western Power is regulated by the state government in terms of how it can earn revenue. Our revenue (through tariffs) is determined by the size of our Regulated Asset Base (RAB).

When streetlights are added to the RAB they have an economic life of 20 years. If a streetlight is replaced or upgraded to LED when it is younger than 20 years old, there’s still some value in there that we haven’t recovered back yet.

Sometimes your circumstances change and you may need to cancel or change the information within your application after you have submitted it to us.

If you wish to change the scope of work in your application we will first review the change and then either:

continue the project with the variation and invoice you for any additional materials, design work and remobilisation costs incurred. We will typically only take this approach when the change is very minor.

or

 if the change is significant we will cancel your project. You will need to submit a new application with your new requirements.
