Instant power – it’s what we all expect. It’s easy to take it for granted, until we don’t have it.
We’ve built our lifestyles on the availability of a steady stream of electricity to run our fridges, TVs, pool pumps and everything else that we charge from our power points.
When your power goes out – it’s no fun. Annoying, inconvenient, you name it.
It’s Western Power’s job to keep your grid connection humming, and we mostly do a good job of it – the average customer is only without power for three hours each year at an average reliability of 99.93%.
That’s pretty reliable – even if those three hours feel like three days without power!
But there a lot of customers who do have more frequent and longer power outages – particularly those on the edge of the electricity network in regional Western Australia.
Our current trials in Ravensthorpe (stand-alone power systems) and Perenjori (network battery) are designed to improve power reliability and reduce the likelihood and impact of network outages.
Throughout the year, we deliver ongoing maintenance and upgrades to our network, and our emergency response crews are always on call in case of a fault or electrical emergency. Our efforts are all to keep you network-connected with a reliable power supply.
It’s also in our best interests, as we live and work in the same communities as you – keeping the lights on is important for all of us and we’ll continue to develop ways to improve your reliability.
Reliability differs due to environmental and geographical factors – for instance a regional community at the end of a long, single powerline may have more frequent and longer outages due to the line’s increased exposure to the elements, falling/overgrown vegetation and dirt build up. It also takes longer for crews to find and fix faults across lines that are hundreds of kilometres long.
Customers in the metro area generally have better reliability as the interconnected network allows for power to be redirected – known as backfeeding – if one part of the line has a fault. Plus our crews are generally able to mobilise quicker.
