FAQs

  • Do I need permission from my strata company before applying for my connection?
  • What is Regulated Asset Base (RAB)
  • What if I change my mind or want to cancel my application?

Strata schemes typically have a single connection point to the Western Power network that determines the total allocation of available electricity supply and generation capacity to be shared by all strata lots.

This connection point has a fixed capacity, so it's important for strata lot owners and prospective purchasers to be aware of the arrangements and obligations relating to the connection, as it may restrict their ability to install equipment such as home EV charging stations, rooftop solar panels and batteries.

Before applying to connect this type of equipment, strata lot owners should... Read more

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:
