The text below is the transcript from the Long Power Outage Brief video. An audio-described version of the video is also available.

VO: Sometimes we may have to remove the power supply for an extended period of time. This could take up to eight hours for some complex, but vital pieces of work. This might mean connecting a new substation, replacing an old or decayed pole, moving machinery near a power line or fitting a new piece of equipment to the power network. In these circumstances, we will always contact you well in advance to allow you to plan ahead. We will send you a letter giving details of when and for how long we think the power will be off. And also let you know what we are doing. We plan our work to keep these power outages to a minimum and try to ensure that we complete the work within the allocated time.
