TransGrid presented with international award for Mobile Plant Framework

​Congratulations to the TransGrid Mobile Plant Framework project team who have received a Silver Award in the annual Intranet & Digital Workplace Awards.

Now in their 12th year, these global awards recognise outstanding contributions to the fields of intranets and digital workplaces. The awards uncover remarkable solutions that deliver business value.

TransGrid's Kersha Levi, Manager Field Support, was thrilled to accept the award with the team and said: "The award provides recognition of the process improvements delivered for the business and awareness of the team's fantastic work in bringing field work, safety and systems together to deliver efficiency." 

What is the Mobile Plant Framework Project?

The Mobile Plant Framework (MPF) project automated components of the MPF procedure using Mobile Plant through the development of a bespoke app. This provided significant administrative efficiencies and insightful reporting reducing human error, and ensuring safety standards were applied consistently across the business.

The changes reduced the paperwork and administrative time required to meet compliance obligations in the field for operating plant. While an element of paperwork is still involved in each job, the deployment of the MPF app has resulted in a reduction of 80 pages per job to 11.

Our Resource Schedulers now have greater visibility when allocating resources to a job. They can easily see in one view that plant resources are serviced, maintained and suitable for the job and that the human resources allocated are both qualified and experienced to operate that plant.

Employees on site can have the confidence that the plant that is on site is ok to go and the site managers have the right resources. Workers can complete relevant checks and then if they feel there's something wrong with the plant they have the power to act upon that straight away.

A few comments from the judges:

"I like that the result has not just been a reduction in incidents but also an increase in efficiency. This is not seen very often!"

"This is the kind of frontline worker digital employee experience that we've been wanting to see more of for some time. A very clear focus on an essential issue make this well suited to an app. I like that they didn't try to make it an all-encompassing solution, but stuck to doing one thing well."

"Working on power lines in the field is dangerous. This bespoke app helps to improve frontline safety, as well as increasing productivity and reducing costs. Very specific to their needs, but a good example of integration with different systems and empowering field staff."

Well done to everyone involved in the development of this application and the accompanying Procedure!

A day in the life of a TransGrid Graduate
Name: Kurt Blowes
Job Title: Graduate Electrical Engineer- Technical Support Substations
University Attended: University of Newcastle
Degree: Bachelor of Engineering (Honours) (Electrical)
Graduated: 2016


Woken up by alarm to a brisk morning in Tamworth. A little far from home but there is a buffet  breakfast waiting downstairs with my name on it.

I am in Tamworth after travelling up yesterday for a fault investigation on a failed Capacitor bank can. Bulging on one capacitor can was identified during a visual inspection as a result of the Protection tripping the Capacitor bank. The fault was decided to be investigated further after testing of the Capacitor bank showed no problem, however an issue was identified following an analysis of the Protection fault records. Simulations were ran and the results were found to be similar to the protection fault records supporting the theory that there were repeated spark overs across one row of capacitor elements in one of the capacitor cans

6.30am - a day in the life blog.PNG


Time for the long 5 minute drive to the Tamworth Depot.


Introduced to some local staff. It is always good to meet staff face to face having talked to them over emails and phone calls many times.


Set up Laptop and check emails, responding to any priority work. This can involve planning or estimating customer work, providing support to maintenance staff, Fault investigations, reporting and documentation reviews. Can't forget to also make myself a coffee.


Meet with team for risk assessment and discussion on hazards, controls and how the day's work will proceed.


Carried out inspection and analysis of the dismantled Capacitor Can. Closer inspection showed evidence of low energy discharges to the tank at the ends of the top 3 or 4 capacitor element. This further supported both the simulation and protection fault record findings.

Each Capacitor element is a long, flat sheet consisting of Dielectric and foil layers. This is then rolled up to form each element. The two foil layers are offset to avoid shorting once the ends of all the elements have been soldered together.

I had previously never seen inside a capacitor can, however I now have a good understanding of the internal construction as well as fault finding of capacitors.

8.15am - a day in the life blog.PNG


Finished gathering evidence for Investigation. Brief discussion with team on findings.


Time to get on the road back to Newcastle.


Taking care of lunch and fatigue management with a stop in at Wallabadah on the way back to Newcastle. The burgers are worth stopping in for.

12.30  a day in the life.png


On the road again. Travelling back with Senior Support Engineer allowed time to be able to reflect on the findings and discuss any technical questions. Lots of time to pick out as much knowledge as I can from him.


Arrived back at Newcastle Depot. Finalised the car pool booking and returned the keys just in time to call it a day. 7.47 hours done, got to love a working a 9 day fortnight.


Whip up some dinner


Fit in a gym session now that it should be a little less busy.


Finish the day off with a shower and bed, ready to piece together all of the Information gathered from the investigation the following morning.

Surging Forward - Electric Vechiles

We were proud to contribute to the Partnerships Conference Magazine as part of the 2018 Infrastructure Partnerships Australia Conference. Our article discusses the rise of electric vehicles in Australia and their impact on the energy network.

"According to the International Energy Agency, in 2017 the estimated global electricity demand from all electric vehicles was 54 terawatt hours (TWh) – or around 80 per cent of the annual electricity demand of NSW.

…For grid operators like TransGrid, there are opportunities to maximise the benefits of electric vehicles in the form of optimising vehicle charging time, and the potential for electric vehicles to provide small-scale energy storage.

While there might be some challenges along the way, we firmly believe that an electric vehicle future is coming. If welcomed and supported, Australia will experience significant economic, environmental and social benefits not only for users but for society at large."

Bushfire prevention: behind the scenes of an aerial patrol

“In the chopper, we’re communicating the whole time about the electricity lines and the space that surrounds them. We sweep our eyes side to side through the nearby vegetation, then up each tower structure, checking the condition of the earthing and insulation in particular.”

Meet Brenden Secombe, one of a team of specialists selected to patrol our network by helicopter ahead of bushfire season to identify maintenance that will minimise bushfire risk. 

The patrols are vital to the safety of communities nearby lines, and for the safe and continual supply of electricity across the State. 

The teams in the chopper are in the air for approximately eight hours a day, fly over a transmission tower every two minutes, and travel at up to 40 knots an hour. 

Boarding the chopper_TransGrid.jpgVegetation near transmission line_TransGrid.jpg
View from the top (L to R): Patrolling the lines; recording potential risks; boarding the chopper; vegetation near a transmission line. 

On a transmission network that spans 13,000 kilometres, it’s vital to record all potential hazards quickly and accurately. 

There’s a pilot and two people to check the transmission line and surrounding area. One checks for vegetation that’s growing too close to the line, and the other checks for maintenance that’s needed on the line. 

Also flying the lines is Andrew Brice, who brings over 30 years of industry experience, including emergency repairs by helicopter.

“If we see something than needs urgent repair, we report it immediately. For the most part, we record location, proximity to the transmission line, and exactly what the issue is,” says Andrew.

“From the air, we see the lines end-to-end, and can get up close to things we simply can’t see from the ground,” says Brenden. 

This information is passed to teams who carry out the maintenance work. The patrols and resulting maintenance work are vital to minimising risk on the lines and surrounding areas ahead of summer. Hot summer days are typically when bushfire risk is highest, and also when the network is under pressure to supply the most electricity. 

“There are a few hard yards involved, but it’s a good feeling to know that we play a part in keeping the network in good working order. At the end of the day, it all comes back to keeping people safe,” says Andrew. 

2018 aerial patrol dates and locations

In 2018, aerial patrols are occurring from April to August. For a list of patrol dates by location, view Aerial Patrols: Safeguarding your network against bushfires

Aerial Patrols: Safeguarding your network against bushfires

If you see a low-flying helicopter moving along the electricity transmission lines, you've likely spotted a chopper on an aerial maintenance check. Each year, helicopters patrol almost 13 000 km of transmission lines and infrastructure that make up TransGrid's network. Teams aboard the choppers look for infrastructure that needs to be repaired, or trees and shrubs in easements that could pose danger in a fire or storm.

Patrols reduce risk in the event of a bushfire or storm

Maintenance patrols are vital for the safety of communities nearby easements, and for the safe and continual supply of electricity across the State. 

You likely know that scrub can burn quickly and with devastating impact on a hot, dry day. You may be surprised to learn that a 10 metre tall tree can have a flame height of more than 30 metres in a bushfire. It’s vital that clearance zones are observed in transmission easements.

Young women step into STEM

Seventy-five per cent of jobs in the future will require STEM skills, yet women currently occupy just 16 per cent of STEM jobs, according to a report from Australia’s Chief Scientist.  

Australia is faced with not only the challenge of more equal gender representation in STEM, but with skilling young people for the future employment market.It makes financial sense: women represent half of the global population, so their participation in their workplace is vital to national productivity and economic growth. 

Rebecca El-Khoury, TransGrid Regulatory Analyst, has qualifications in actuarial studies, applied finance, and economics; and an enthusiasm for inspiring young women to pursue STEM careers. 

Rebecca recently spent four days mentoring a group of high-achieving female students at the 2018 University of Wollongong Women in STEM camp. The camp connects 15 and 16 year old students with professionals in STEM industries to help them better understand career pathways. 

One of the greatest experiences of the camp was making the girls aware of the range of opportunities that they can pursue, explains Rebecca.

“One student who excels in science and sports was connected with a biometrics specialist. It opened a whole world of possibility, well before that student makes a decision about her university study and ultimate career path,” says Rebecca.

STEM camp 1 - Copy.jpg STEM camp 3 - Copy.jpg STEMP camp 2 - Copy.jpg STEMP camp 4 - Copy.jpg

“For me, that is the key to the camp – helping educate young women about the opportunities that they can pursue professionally. There was nothing like this when I was at school. I didn’t consider becoming an engineer, partly because I just wasn’t aware of it as a pathway.” 

“It’s fantastic for the girls to see female engineers, scientists and economists say: ‘We do exist and the career prospects are really great’,” says Rebecca.

Here at TransGrid, we support opportunities such as these to educate young women about career opportunities in non-traditional roles, as well as STEM more generally. It’s one way that we ‘press for progress’ on International Women’s Day, and all days of the year. 

Reflecting on the experience of being a mentor at the camp, Rebecca is positive about the knowledge that the girls took away. 

“There was a real thirst for knowledge and learning. A lot of the girls asked for advice about selecting a university degree, and the kinds of career pathways that might open up as a result.”

“Empowering girls to be leaders of change is vital. Any initiative that gives women the knowledge, resources and information to go into STEM roles is really good – particularly when it’s something they haven’t previously considered,” says Rebecca.

Have your say 

The World Economic Forum's 2017 Global Gender Gap Report estimates that gender parity is over 200 years away. What else do you believe we can do to realise gender parity sooner?

Tower power: how we cut down design time by almost 30% and increased the accuracy of models

​One bolt out of place by even a centimetre, and an entire section of an electricity transmission tower might have to be delivered again. 

First, there is a risk that the tower will not fit together at all. In addition, the most minor of misalignments between sections of the tower can compromise its strength and safety, and your energy supply. We have strict design and quality checks in place to ensure that works are delivered on time, and make efficient use of materials. 

As you can appreciate, cutting corners in tower design is a false economy. The risk of fabricating tower parts that don’t fit together perfectly is significant in terms of additional time and money. We set ourselves a challenge: how can we deliver towers more efficiently, without compromising design, or risking errors that could delay construction of the tower? 

The solution; a specialised modelling software, has reduced tower design time by almost 30%

The software has greatly reduced the risk of delay during factory “trial assembly” as there is more certainty in the design and accuracy of fabrication drawings provided to the manufacturer.

 Tower model.png
Model making: 3D tower visualisation 

The software allows engineers to design the tower in 3D (to ensure all elements align), then export the specs direct to a 2D plan. Below are examples of tower design in action.   This significantly fast-tracks the production of the tower, so that the team can assist more clients, and deliver work that is of the highest quality. 

3D Tower model.jpg2D tower model.png

Image B: 2D drawing output from 3D model in software  

Firm footing

Did you know that the feet of every transmission tower have to be individually designed for the land they stand on? Hilly areas in particular require precise modelling to fit the tower to the land. Comprehensive mapping of the site is done before a designer begins work on the towers. 

Making design a reality 

The team visited a manufacturer to quality check the output of the new design process. Following this success, the first of the towers will be delivered to TransGrid for construction later this year.

How to get an easement development assessment done efficiently and cost-effectively

Renovating or developing your property, or a client’s property? This is how to get through the planning process efficiently and cost-effectively when you have a high-voltage electricity easement on your land. 

We work with you to check that the proposed works and the existing electricity lines can co-exist safely on your property. The priority is to ensure that your friends and family, or tenants, will be safe on the property.

1. Find out if there is an electricity easement on your property, and who maintains it

Determine whether you have an electricity easement on your property. Your conveyancer or property lawyer can confirm this with Land Registry Services (LRS). If your property has an easement, the LRS will tell you who owns the infrastructure.  In NSW, there are several electricity networks: the high-voltage powerlines are operated by TransGrid. We will work with you to ensure that the planned renovation or development maintains a safe clearance from powerlines and other network infrastructure. 

2. Seek TransGrid’s permission to develop near the powerline 

Contact us to secure advice about what you need to supply to TransGrid, and what you can expect from TransGrid. Each development is different, so advice will be specific to your plans. 
Easement development enquiry process.PNG

Based on feedback, we’ve streamlined the enquiry process so you have permission for an easement development before lodging a Development Application (DA) to your local council. This ensures that the process is as efficient as possible, and reduces risk of incurring additional costs to modify your DA. We’ve also reduced the permission  response time from over 2 months to under 21 days.

Time-saving tip: Provide site plans in 3D DFX or CAD file formats

Our engineers and network designers need files in 3D DFX or CAD formats to model the proposed development alongside our network. This is done to ensure that there will be no safety or clearance issues on the site as a result of the development. 
  • 3D DFX (preferred)
  • CAD
  • PDF only accepted for very basic easement development proposals.   

What is an electricity easement? 

An electricity easement is the right held by TransGrid to control the use of your land near above-ground and underground power lines and substations. We hold this right for your own safety and to allow staff to work on the power lines at all times. Easements also exist for telephone lines, water and sewage mains and natural gas supply lines.

 Why are easements necessary? 

Easements ensure the safety of the residents living, working and playing near power lines. Easements are also created to give TransGrid clear, 24 hour access to the power lines. It is important to keep the easement clear at all times so regular maintenance, line upgrades, damage or technical faults can be attended to immediately.

Critical Enabler: TransGrid and a renewable evolution

​Amid continued renewable energy investment in Australia, an increasing number of utility-scale renewable projects are continuing to be connected to the National Electricity Market (NEM), and ultimately supplying electricity to end consumers. 

Amongst this flurry of activity, TransGrid is facilitating a number of critical network connections for renewable projects in New South Wales and Victoria. 

Connecting 380,000 megawatt hours of renewable energy to the NEM

In Southern NSW, TransGrid will be connecting an additional 380,000 annual megawatt hours (MWh) of electricity to the grid via Neoen’s Coleambally Solar Farm. The project, which has secured funding to proceed with construction, will supply enough energy to power 52 000 homes. Works at the solar farm started in January and will be completed by the end of the year, while connection works undertaken by TransGrid are scheduled to commence in March 2018 and will be commissioned by July 2018. This work comes on the back of TransGrid successfully connecting Neoen’s Parkes and Griffith Solar Farms to the NEM in 2017.

According to Darren Clarke, TransGrid Customer Engagement Manager, renewable connections to the NEM are vital for future energy supply.
“The scheduled decommissioning of baseload coal-fired power stations over the next few decades means that investment in projects such as Coleambally Solar Farm will be critical in securing long-term affordable, reliable and sustainable energy for consumers,” says Darren. 
“Naturally, there are challenges that all participants involved the energy system have to overcome in this transition, but TransGrid is willing and able to take the lead in ensuring transmission networks enable this transition to occur in an efficient manner."

Neoen is committed to leading the transition to a renewable future, explains Chris Leonard, Deputy Head of Development, Neoen Australia. 
“Coleambally Solar Farm contributes to our target of 1GW of renewable capacity by 2020.”
“TransGrid has been a critical enabler of the project, and shares our commitment to a renewable future.” 
“Based on previous projects, TransGrid’s support and responsiveness from the initial enquiry stage to the physical connection has allowed Neoen to focus on delivering its solar farms and manage its time more efficiently,” says Chris.

“We look forward to collaborating with Neoen to successfully deliver the project. We’re absolutely committed to providing complete peace of mind for Neoen through the planning, development and operation of our network connection infrastructure at Coleambally Solar Farm.”

“Fundamentally, through developing  confidence in TransGrid’s ability and to deliver and enable them we want to allow customers such as Neoen to be able to focus on connecting efficient and advanced renewable technology to the market,” says Darren.

TransGrid identifies top six energy zones in NSW and ACT to meet future need in the National Electricity Market

​Over the next two decades, the national energy system will be substantially reconfigured as existing coal fired generation retires from service. In New South Wales alone, around 8,000 MW of coal fired generation capacity is expected to retire over the next 20 years.

 Retirement of coal generation_NEM.PNG
System of the future: Possible 50 year retirement of coal-fired generators in the NEM, via Australian Energy Council 

Significant volumes of new generation will be required to maintain energy security during this transition and large scale renewables represent the lowest cost replacement technology. 

TransGrid has identified three renewable energy zones in NSW in a move to develop a plan for future energy needs in collaboration with other networks and the Australian Energy Market Operator (AEMO). Under the banner of the AEMO-led Integrated System Plan, transmission network service providers and other system participants are exploring how to jointly develop the National Electricity Market to meet future needs.

The activity follows a recommendation of the Finkel Review, which emphasised the need for an Integrated System Plan. The Review observes that:

“Incremental planning and investment decision making based on the next marginal investment required is unlikely to produce the best outcomes for consumers or for the system as a whole over the long-term or support a smooth transition. Proactively planning key elements of the network now, in order to create the flexibility to respond to changing technologies and preferences has the potential to reduce the cost of the system over the long term”.

TransGrid has identified areas with: 
  • Abundant renewable energy
  • Existing network infrastructure with capacity to connect new generation 
  • Proximity to population centres where energy is consumed. 
Of six contenders detailed below, those seen to be the most feasible and cost effective are: Northern NSW, Southern NSW and South East NSW and ACT. 
The strategically planned connection of large scale energy zones - supported by greater interconnection - would provide consumers with the lowest priced energy and greatest system security. 

The benefits include: 
  • Connection of the lowest-cost generation in regions with the best quality renewable resources.
    These large scale generators can operate at higher capacity factors and are able to supply electricity to consumers at lower unit costs than generation in lower quality renewable resource areas. 
  • Efficient transmission connection through economies of scale. Geographic diversity of renewables across the National Electricity Market (NEM) to provide lowest cost intermittency firming. 
  • Sharing of energy and ancillary services across regions to provide system security and resilience.
    The transmission network provides a platform for the lowest cost electricity generation to be connected and dispatched, enhancing energy market competition.
These priority zones have high quality solar and wind resources, compatible land use with low opportunity cost and low transmission augmentation costs. They are located on corridors between major population centres and maximise the use of the existing network.

The delivery of transmission connections to these zones should be staged over time so that lowest cost connections for new capacity in priority energy zones are completed first, new generation connection is enabled ahead of expected thermal retirements, risk of asset stranding is minimised and future optionality is preserved.

There are currently unprecedented volumes of connection enquiries to the New South Wales transmission network, with over 30 GW of wind, solar and pumped hydro projects at various stages of development. Only a fraction of these projects can be accommodated in the current network.

For more information, refer to TransGrid’s submission to the Integrated System Plan consultation, led by AEMO.
