Working
for you

Powerco is here to bring power to your door.  You buy electricity from your retailer, and it’s our job to look after the lines, cables, poles and other electrical equipment that get it to you from the National Grid, safely, reliably and efficiently. 

We’re committed to keeping the power on for our customers.  To ensure our network remains resilient, we routinely undertake maintenance and upgrade projects.

We understand that some of our maintenance and upgrades can cause inconveniences to our customers, so we are working hard to keep you up to date with information on how each project is tracking, and how you may be affected.
