Some outages are caused by unexpected damage or issues on our electricity network.

What causes unplanned outages?

Unplanned outages happen when our electricity network has an issue or gets damaged. This is usually caused by severe weather, fallen branches and trees, animals making contact with powerlines, traffic accidents, vandalism, theft and sometimes underground cable damage.  

When this happens, physical construction works are often required. This includes repairing or replacing assets, such as power poles or transformers. We always assess if we can fix a fault safely, which is sometime impacted by lighting, high winds, extreme heat, fires, physical location and local geography.
