Geurie and Surrounds: Network Upgrade

In parts of Dubbo and the surrounding communities, we're making some big upgrades to our high voltage electricity network which supports homes, businesses, industry and the mining sector - from Wellington through Dubbo to Cobar and beyond. This will help us keep providing you with a safe, reliable, and resilient power supply. It will also allow us to connect new loads and renewable energy sources to the network.

One of the major changes you'll notice is the replacement of some of our existing timber and concrete power poles. The new poles will be taller and made of steel, meaning they’ll look different to the poles that you see now. We'll also be stringing new overhead wires. These significant visual changes are part of our efforts to improve the network.

Our local Essential Energy teams, along with contractors, traffic controllers, and specialists, will be carrying out these major works. We're working in many locations and will do our best to minimise disruptions to the community. Over the next 12 months, you might experience some power outages, general construction activities, and occasional road closures - we’ll have traffic control in place. Customers impacted by power outages will receive prior notification.

Please follow along here for all the latest news, project updates and information.

Update on Construction: Geurie Zone Sub Station to Maryvale Solar Farm

Share Update on Construction: Geurie Zone Sub Station to Maryvale Solar Farm on Facebook Share Update on Construction: Geurie Zone Sub Station to Maryvale Solar Farm on X (formerly Twitter) Share Update on Construction: Geurie Zone Sub Station to Maryvale Solar Farm on Linkedin Email Update on Construction: Geurie Zone Sub Station to Maryvale Solar Farm link
What is happening
Essential Energy is building a new high‑voltage powerline between Geurie Zone Sub Station and the Maryvale Solar Farm from May-Dec 2026.
Once built, this powerline will connect the solar farm to the electricity network so the power it generates can be safely carried to homes and businesses across the region.
Why this work is needed
This powerline:
allows electricity from Maryvale Solar Farm to enter the network
supports renewable energy in the Central West
helps strengthen reliability of the local electricity system
Where the works will occur
The powerline will be built along a new corridor between Geurie Zone. Substation and the Maryvale Solar Farm
It crosses privately owned rural land, as well as areas near existing roads and infrastructure, including the Mitchell Highway
Landowners directly affected by the route are aware of this construction and have been consulted for some time.
What will the new poles look like
The new poles will consist of some single steel poles and some concrete ones, approximately 30ms in height.
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
What construction will involve
During construction, nearby residents may notice:
survey and site access vehicles
construction crews accessing paddocks or existing tracks
construction of steel and concrete footings
installation of steel and concrete poles
stringing of powerlines between poles
periods of increased traffic and reduced speeds at times on local roads and the Mitchell Highway
Possible outages for customers between July and October 2026. Essential Energy will contact impacted customers ahead of time.
Work will be staged so that not all areas are active at once. Some noise and dust are expected from construction activities. We’ll work to minimise this wherever possible.
Works will be from 6.30am-6.30pm Monday – Saturday

Steel poles will be used to replace existing concrete poles and in rural areas, the H-pole structures, to support the upgraded network.
The final pole design will depend on local site conditions, engineering requirements and environmental considerations. Most poles are expected to be between 28 and 34 metres high, and pole locations, heights and foundation designs will be confirmed following:
survey works
geotechnical investigations
environmental assessments
detailed engineering design.
Typically, the project will use dual-circuit 132kV structures, with concrete footings, strung on both sides of the pole, as pictured below.

Corridor where works will likely take place - current easement is 45m in width

Site investigations will commence between Geurie and Dubbo in November 2025 to understand local ground conditions, and any cultural and ecological sensitivities. Surveys will take place predominantly in Essential Energy’s existing easements and powerline corridors. However, at times, access to the easements may be required via private land. If this is the case, Essential Energy will contact landowners and seek landowner consent before accessing the property. This would include an understanding of any requirements such as biosecurity restrictions, and preferred access procedures and locations.

Site investigations will involve taking soil and rock data or samples using low-impact methods, such as small diameter borehole drilling and cone penetration tests. Visual inspections will also be carried out, focusing on ecology and Indigenous heritage. These investigations will also allow Essential Energy to better understand how to configure any future network upgrades to minimise impacts on affected landowners.

Depending on individual site characteristics, equipment used in site investigations may include:
Track-mounted drill rigs
Support Trucks
Float Trucks
Light commercial vehicles
Investigations will likely result in some noise and dust. At the conclusion of the investigations, sample holes will be backfilled, capped and covered. The time for each borehole varies, with works generally completed in one day. If the work extends beyond a day, the drill rig may remain onsite overnight (with owner’s permission).
In the event that rock core drilling is required (rather than just an auger), water will be used. When the hole is finished, the water used during drilling is poured down the hole and the small amount of excess is tipped on the ground.
Work hours will be 7am – 5pm.

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.

Learn More and Have Your Say

To keep you informed and hear your feedback, we’d like to offer you three opportunities to connect with our team and discuss the works at our upcoming community drop-in sessions:

Tuesday 17^th March: 5-8pm at Wongarbon CWA Rooms,
