We use thresholds to help determine ‘competing’ load applications as part of our Applications and Queuing Policy (AQP). Thresholds are currently defined by demand values for a given load area or network region.

Following a review of the threshold levels in June 2014, we revised our ‘Non-Competing Application Thresholds’ test and will now only consider new load applications which meet the following two criteria to be non-competing for the purpose of the AQP.

  • The total load must not exceed 1.5 MVA for its National Metering Identifier (NMI), and
  • The load application must be eligible for network... Read more

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.
