What is the ERT trial?

SA Power Networks is conducting a trial to improve how we communicate ERTs during unplanned outages. This trial responds directly to customer feedback that current outage time estimates can sometimes be inaccurate.

• Current system: ERTs are generated automatically using historical data based on the type of outage.
• New trial system: ERTs are provided by repair crews on-site, based on their real-time assessment of the outage.

What’s changing?

Current approach	ERT provided shortly after an outage is reported Based on automated, historical data
Trial approach	ERT provided once crews arrive on-site Based on real conditions and crew assessment May take longer to receive, but will be more accurate Updated if needed as repair work progresses

 

How you’ll be notified

Under the trial, customers subscribed to outage alerts will receive three updates instead of two:

1. Outage acknowledged
   We confirm the outage and advise that more information will follow
2. Estimated Restoration Time (ERT) provided
   Shared once crews assess the situation on-site
3. Power restored notification

This ensures you stay informed throughout the entire outage process.

Why this matters

While there may be a short delay in receiving an ERT, the benefit is a significantly improved level of accuracy.

We believe this will help customers plan better and reduce uncertainty during outages.

What if there are multiple outages?

In situations involving widespread outages (such as severe weather events affecting multiple areas), this trial system will not operate.

This is consistent with the current approach, where ERTs are not provided in large-scale outage events.

Who is included in the trial?

The trial is being conducted in selected locations only, chosen because:

• They have historically experienced less accurate automated ERTs
• They represent a mix of geographic areas
• They are unlikely to experience overlapping outages

The trial does not include areas with significant planned works underway.

In situations involving widespread outages (such as severe weather events affecting multiple areas), this trial system will not operate.

How long will the trial run?

The trial will run for three months:

• Trial starts: 8 July 2026
• Trial ends: 8 October 2026

We will monitor customer feedback throughout the trial. If the new approach does not improve customer experience, we may stop the trial and return to the current system.
