Western Australia

01The problem

Help arrives too late.

Utilities hold a lot of data on how customers pay and use power. Yet support usually starts only after something goes wrong.

GreenSpark 2026 Use Case 3, set by Rennie Advisory: an early warning and intervention tool for customers at risk.

Reactive

Support starts after a missed bill, a debt or a disconnection notice.

Hidden

Many people never ask. Stigma, fear and complexity keep them quiet.

Forecastable

Heatwaves are forecast days ahead. That is a window to act.

In a heatwave, a common harm is simple. A household switches off its cooling to save money. Exactly when it matters most.

02The engine

Four signals. One plain-language reason.

No black-box score. Every flag shows the signals behind it, in words a busy officer can read in seconds.

  • Financial

    Missed or late payments. Failed direct debits. Rising arrears.

  • Usage

    Sharp drops in use. Odd patterns in extreme heat.

  • Engagement

    More calls about bills. No reply to messages.

  • Climate

    Heatwave, cyclone or flood forecast nearby.
