Why do we need underground power?

Underground power is proven to be safer, more reliable and more aesthetically pleasing than overhead power lines. This is particularly relevant to the Pilbara given the extreme weather conditions experienced in the region. Much of the network in the Pilbara is nearing, the end of its useful life. Rather than replacing with overhead network, it is timely to install underground power.

What towns will be completed in this project?

Karratha, South Hedland, Onslow and remaining overhead network in Roebourne

Will I have to pay for the upgrade?

A. The project is funded primarily from the State Government's Royalties for Regions program. However, your local Council will be contributing 25 per cent to the project. It is normally the process that the funds are recouped from those that benefit directly from the project, therefore adding a charge to the rates is historically the way to raise these funds. However, it is up to your council to determine the method they wish to use.

Which town will go first?

The project commenced in Karratha in October 2010. The project will head to South Hedland in the middle of 2011, with Roebourne and Onslow to follow.

What happens if you damage my yard or verge?

Skilled contractors will be engaged to carry out the works, however, occasional damage can occur. If that happens, your property will be reinstated to a standard similar to that, which was existing. The program will include photography of the existing property prior to site works commencing and again on completion of the works to verify the contractors take every care with your property.

Will you be digging up the roads?

When there is a requirement to run cable across a road, an underground directional drill will be used, as far as possible, to reduce any damage to roads.

Will my power be switched off because of the project?

Yes, there will be a requirement to turn the power off to your property at some stage of the project. Horizon Power will endeavour to plan the outage time and duration so as to cause the least possible disturbances to householders. You will however, get adequate notification of when your power will be going off, and for approximately how long.

Who do I call if I have any problems?

As the operator of the project, your initial point of call will be to Horizon Power. As a key partner in the project, your Local Government will also be a contact point.

You will receive a letter in the mail when the project commences, which will provide you more specific information about who to talk to if you have any issues.

How does the work take place?

Detailed newsletters will be delivered to every household outlining the details of the project including proposed schedules, work which will be completed on your property and information on any interruptions to your power supplies.

Is it possible I could dig underground and electrocute myself?

Prior to digging it is essential that you determine the location of any power lines or other utilities that may be on your property. Contact Dial Before You Dig on 1100 to find out the location of any power, water or communications services.

Warning tape is installed as part of the underground process to give a visual cue that you are digging in the vicinity of power lines.

How will public safety be ensured throughout the life of the project?

Horizon Power will ensure that highest level of safety is demanded of its contractors and effectively monitored. If you observe any safety risks or unsafe work practises, please notify us immediately by contacting 1800 267 926 or email pupp@horizonpower.com.au

How long will it take to complete the project?

The project commenced in Karratha in October 2010, and is scheduled for completion across all towns by the end of 2012. These timeframes are, however, only indicative as this type of work is largely affected by weather conditions such as cyclones. Unpredictable weather events can cause major damage and long delays to such a project.

Is streetlighting a part of the program?

As most of the existing streetlighting is located on the power poles which are being removed, new streetlighting is being installed. Each Council involved in the project will approve the streetlighting design as per the Australian Standard.

What does a voltage upgrade mean to the people of Karratha?

Currently, the amount of power available in Karratha is limited to the size of the lines that carry it. When the power is put underground, the new power cables will have greater capacity, allowing for up to 1000 new residences in Karratha. This upgrade will only affect the high voltage, it won't have any impact on current properties. You will still receive your power to your house at 240 volts, meaning that you won't have to change any of your electrical equipment.
