Dubbo and Surrounds High Voltage Upgrades

What is happening

• EE staff and contractors will be involved in land surveys, geo-technical investigations (including ecological and cultural heritage studies) on both sides of the Mitchell Highway between Wellington and Dubbo
• Once design is approved, construction will commence between Wellington and Geurie (South-Western side of the highway) in August 2026
• Consultation with affected landowners, community groups and key stakeholders has commenced and will continue throughout these works

During Site Investigations and Construction

• You’ll see a range of machinery and equipment, including drill rigs, trucks, excavators and cranes being used. There’ll also be elevated work platforms/cherry pickers in operation and equipment used to string wires between power poles.
• Some noise and dust are expected from construction activities. We’ll work to minimise this wherever possible.
• There’ll be an increase in vehicle activity while crews are on site. Traffic management will be in place to maintain access for residents and provide safety of the public and workers.
• For safety reasons, there will be times where power will need to be temporarily interrupted while the work is completed. Residents affected by planned outages will receive Essential Energy's standard outage notification advising the dates and times of outages affecting them, closer to the outage dates.
• When new galvanised steel power poles are installed, their shiny surface can cause temporary glare. Natural dulling occurs over time as they are exposed to sunlight, rain, and wind.
• To keep the network safe and maintain reliability, we’ll be working with local councils and landholders to manage or remove vegetation, and replace where appropriate.

In March / April 2026, we will be we will be replacing existing timber and concrete power poles with new, taller steel power poles and stringing new overhead wires in the Southlakes region (the area indicated in the Section 4 to 5 map below). The works will take place between 7.00am and 6.00pm Monday to Friday, and 8.00am to 1.00pm on Saturdays, conditions permitting. The works are expected to be completed by November 2026.

We will be hosting a community drop-in session at the shade structures in Southlakes Park (between Southlakes Parade and Boundary St) on Saturday 14th February from 9am to 2pm.

When new galvanised steel power poles are installed, their shiny surface can cause temporary glare.

Natural dulling occurs over time as the galvanised steel poles are gradually exposed to environmental elements such as sunlight, rain, and wind. This leads to a thin layer of zinc oxide and other compounds forming on the surface, creating a matte, grey finish that significantly reduces glare. This process is known as patination, and enhances the pole’s resistance to corrosion, offering a protective barrier without the need for chemical treatments or coatings.

Glare from steel poles is a challenge that all electricity networks face and prior to construction we explored treatment options such as dulling agents, painting, and vinyl wrapping to reduce glare.

Although dulling agents can reduce initial glare, they ultimately produce the same result as natural weathering. Applying a treatment to the poles being installed in Dubbo was found to have a significant impact on project costs without offering a lasting improvement over what would otherwise occur naturally.

Applying paint to galvanised steel poles introduces significant maintenance and environmental concerns. During transportation and installation, painted surfaces can be easily scratched or chipped, compromising both the appearance and the protective qualities of the finish. Over time, exposure to the elements causes the paint to degrade and flake, detracting from the visual amenity of the pole and potentially creating a pollution risk.

Vinyl wrapping was also investigated. Moisture can become trapped between the wrap and the metal surface, creating an ideal environment for corrosion to develop, undermining the pole’s structural integrity and reducing its lifespan. Vinyl wraps are also known to be targets for graffiti, leading to further maintenance and aesthetic challenges. The adhesive used to secure the wrap may also deteriorate over time, resulting in peeling or bubbling, which detracts from the pole’s appearance.

After considering these options, we have determined that allowing the poles to weather naturally provides best balanced outcome for managing glare, asset life, and cost to consumers. Natural weathering minimises environmental impact, ensures lasting durability, and resolves glare issues over time. We do recognise that the initial glare from new galvanised steel poles has caused inconvenience for the community, and we sincerely appreciate your patience and understanding as the weathering process takes place.

As we continue to make our way south through Keswick drilling holes, we've been able to commence standing new poles where concrete foundations have cured around Birch Avenue and Hennessy Drive.

See some pictures below of the new poles.

Boring of foundations for the new poles is underway with holes mostly completed between Birch Avenue and the Mitchell Highway. Concrete has been poured which will take a few weeks to cure and then we can return to erect the new power poles in this section.

Next week (26 May), we will commence boring of foundations from Hindmarsh Esplanade, heading south towards our Zone Substation near the greyhound racing club. We don't anticipate any impacts to roads or traffic but there will be noise from the drilling rig as it bores holes during normal construction hours.
