Granny Smith Gold Mine gets greener state-of-the-art energy supply Please see Project Details on Page 18 See Full Story on Page 20

Ian Suckling, Granny Smith Mine General Manager

Why the Grid is essential for a renewable energy future “FAR from being in conflict with

Many people will have heard of the Tesla car and the announcement of the Tesla Powerwall, a residential battery. Tesla uses batteries from the same company, Panasonic, as the batteries currently supplied by ActewAGL. The creator and boss of Tesla, Elon Musk has said batteries need the grid. So will electric vehicles, which are growing fast in Europe, the United States and now in China where vehicles will use renewable energy supplied by the grid.

The CSIRO report ‘Change and Choice’ projected that it won’t be financially viable to consider disconnecting from the grid for many years. The report states, “Disconnecting from the grid as a residential consumer is projected to be economically viable from around 2030 to 2040…”

While the CSIRO report has tried to predict what will happen over time, in a fast paced energy industry it’s not always easy to know the rate of change. But we are a progressive organisation which will always aim to stay ahead of the curve. We are successfully rolling out solar PVs, we are successfully selling residential batteries from Panasonic, and over time our fast charge network will be available for electric vehicles.

I believe the grid will continue to be essential for the continuity of our energy supply and we’re very well equipped to support renewable energy now and into the future. But in the end, customers will decide what the future will be, and whatever our customers want, that’s what we will provide.

But in the end, customers will decide what the future will be, and whatever our customers want, that’s what we will provide.

the drive for renewable energy; the national electricity grid is essential to its implementation.”

Solar PVs, battery storage and electric vehicles have well and truly hit the market and are changing the way we think about our energy use. ActewAGL strongly supports this. We are offering a solar product, a battery storage partnership with Panasonic and a gradual rollout of electric vehicle charging stations across the ACT. There is however a widespread misunderstanding about renewable energy and the electricity grid.

The intricate system of transmission towers, substations, transformers, poles, wires and smart technology is what’s known as ‘the grid’.

There seems to be an idea that if you want green energy and renewable energy then the grid has to go. Yet the PVs on rooftops are only economic because people can feed their surplus power into the grid. Furthermore, the benefits of residential batteries need the grid if they are to be fully realised.

The grid is essential to the large scale renewable projects the ACT Government is relying heavily on to achieve its goal of a city run 100 per cent on renewable electricity by 2025. What the ACT Government is doing is building large scale projects which provide solar and wind power through the grid which is a relatively cheap, reliable and fair way to deliver renewable energy to the community.

It’s cheap because it’s on a large scale; it’s reliable because it is going through the grid, and it’s fair because everyone shares equally with the feed in tariff.

ActewAGL excited to be part of ‘game-changing’ energy storage pilot ActewAGL will play a leading role in the emerging energy storage market following the recent announcement it has been selected to participate in the ACT Government’s Next Generation Energy Storage Pilot. The project will see up to 200 Canberra residents benefiting from subsidised energy storage solutions.

ActewAGL was one of the first Australian energy retailers to move into residential battery storage when it launched a trial in partnership with Panasonic last year. The batteries store surplus energy generated by solar panels during the day and allow for that energy to be used in the evening.

ActewAGL General Manager Retail Ayesha Razzaq congratulated the ACT Government on driving the take up of these emerging technologies. “This really will be a gamechanger for household energy usage in the ACT” she said. “The program will drive awareness of the technology and provides customers with yet another way to take control of their energy usage.

“ActewAGL has a proven track record and is at the forefront of implementing progressive energy initiatives in the ACT, and we’re excited that this partnership will ensure that we will continue to play a lead role in helping Canberrans take advantage of emerging technology.

“With the ACT Government subsidy, customers can add a battery to an ActewAGL solar system starting from $4,990. From there, a typical Canberra household could save over 60% on their electricity bill.

“ActewAGL welcomes this decision and remains committed to working with the ACT Government to further develop the local market

for energy storage solutions”.

Crews combine for Boorowa power boost A contingent of 166 Essential Energy field employees converged on Boorowa recently equipped with 55 elevated work platforms (EWPs) and six crane borers to complete one of the most significant power upgrades and network maintenance projects undertaken in the region.

Boorowa Senior Resource Supervisor, Chris Grimson, said the upgrade involved careful planning and coordination of the various teams working on the extensive project.

“It was an incredible effort – we had crews from 19 depots working across 147 sites removing more than 300 pole cross-arms and replacing them with new insulators and upgrading six power poles,” Chris said.

“We used 55 EWPs and six borers to complete the work as quickly and safely as possible. It was an impressive display to look down the line and see so many crews working on the network simultaneously.”

Regional Manager Southern, Steven Ilitch, said the refurbishment of the high voltage powerline between Murrumburrah and Boorowa had been a large scope of work involving many resources from the surrounding areas.

“Combining the upgrade and maintenance work allowed us to complete two major programs in a short period of time, reducing the impact on our customers,” Steven said.

To further minimise inconvenience to business customers, Essential Energy maintained a temporary power supply to the majority of the Boorowa CBD while the work was completed.

EDMOND Gary Australia recently delivered a TL17M to Essential Energy based in Inverell. The TL17M is a completely new model although from the outside it looks similar to previous machines. The new model incorporates many cutting edge features not seen in other MEWPs on the market. The major composite components of the machine is manufactured from Dura-Comp 40 which is a durable, high dielectric strength composite that has been designed by Redmond Gary Australia specifically to be used to manufacture elevating work platforms.

The TL machine offers the following advantages over current models: •HV rated basket with an integrated liner.

• The Work Load Limit (WLL) capacity is not reduced by the weight of a liner which normally weighs around 50kg • The WLL of the basket has also been increased to 400kg • The basket rotates 180° with no drop off in WLL when rotated • Internal steps and lanyard attachment points are inside the basket • As the fly jib is manufactured from Dura-Comp 40, it is sealed and pressurised, eliminating the need for internal cleaning • All TL MEWPs are electrically tested to 33/132kV rain regardless of the customer’s electrical insulation requirements • The fly jib articulation has been increased to 158° making it possible to raise the fly jib to the vertical position • Machine control is via dual radio remote • Remote and safety systems utilise CANbus with full data logging and diagnostics • Moment sensing jacklegs to improve stability • TL unit continues to offer zero tail swing

• Restricted slew when operating ‘short legged’ Our Customer Support Officer visited the crew three months after the EWP had been delivered to get some feedback from the operators’ point of view.

This TL17M replaced a 23m machine and in the time Essential Energy have had it, there hasn’t been a single job that the operators’ haven’t been able to do, despite the TL17M being a smaller machine.

There is a substantial difference in the flight envelope of the TL17M and this extra versatility makes it possible to approach jobs that couldn’t be accessed previously. The operators told us they could have written pages about the good points of this machine in comparison to other machines they have used.

This success of the TL17M is testament to Redmond Gary’s ongoing support and liaison with many work groups and electrical authorities to get the best possible result for the equipment in service.

Since the delivery of this unit, we have now got another unit on a pacific island and RG will be building approximately 14 more units over the next 6 months.

Clever Composite Poles Pass Every test A.C. Whalan Composites Pty Ltd has been proving how much smarter its composite utility poles are for the last few years and it’s not difficult to see why they are rapidly becoming the preferred option in the delivery of power to the consumer. The CSIRO is the latest in a long line of regulatory bodies to approve this great Australian product and the company’s composite pole continues to pass every test.

One of the main benefits of the A.C. Whalan’s composite pole is the dramatic reduction in installation and maintenance costs when compared to traditional timber poles. This cost saving begins at the point of installation and continues throughout the much longer life of the composite pole.

The ease of installation is also a huge logistical advantage, particularly when expanding or replacing network infrastructure in rough terrain and those hard to reach places.

For instance, A.C Whalan’s composite poles are currently being installed in the Snowy Mountains without the use of heavy equipment or the need for a track or road to be carved out to access the location.

It’s simply a case of a 4WD utility and a small ground crew and within no time at all the pole is up and ready to be ‘networked’.

ActewAGL and Essential Energy are two energy providers who have already signed extensive contracts with A.C. Whalan for its composite utility poles.

Both companies are environmentally proactive and their network switch to the composite pole, not only provides a better ‘network image’ but is more in tune with the environment. Cost wise, it’s a very smart move.

Once installed, the ongoing life costs of the composite pole are negligible when compared to the traditional timber pole and it will last a lot longer in Australia’s extreme climate.

Critically, in a land where bushfires often strike, the composite pole is a winner and far more likely to maintain the security of supply due to its resistance to fire and pests. It’s a wonder that composite poles aren’t mandatory in bushfire prone areas. There’s always a potential for litigation due to the inherent weakness of timber utility poles when stuck by lightning.

Recently, the CSIRO rigorously tested A.C. Whalan’s composite poles specifically for their ability to withstand bush fires and large flaming sources. The poles passed the test with flying colours in accordance with Australian Standards (AS) 1530.8.1.

Mind you, these composite poles have passed many tests since their inception and there is a good reason for that success.

In developing an Australian utility pole to comply and withstand Australian conditions, A.C Whalan Composites began the design process by consulting extensively with Australian utility providers.

During this stage the team from A.C. Whalan covered a multitude of logistical requirements. These included climatic conditions faced; the types of terrain encountered; the physical pressures endured by transmission structures and the various pole lengths required by the power and energy sector.

The end result is a utility pole that, not only conforms to the needs of the energy sector, but one that has been developed to withstand Australia’s tough and diverse environmental conditions.

Fire resistant materials are a big plus in the frontline defence against a raging bushfire and a nonconductive structure is the preferred option when it stands between the earth and a bolt of lightning that’s about to strike.

Unlike old fashioned timber, A.C. Whalan’s composite poles are constructed from fire retardant laminates and the company put that feature to the test with a simulated bushfire attack, producing a large flaming source to do its best on the composite pole but to no avail.

Apart from CSIRO testing, Californian brush fire tests were conducted along with all required fire resistant tests in accordance with Australian Standards (AS) 1530.8.2. The results proved that A.C. Whalan’s composite poles are made of the

right stuff when facing the challenges of Australia’s bushfire prone environment.

As for lightning? A.C. Whalan’s composite poles are inert and non-conductive, a system which was successfully proven to be the case having undergone extensive testing at Ergon Energy’s dedicated testing facility.

The range of tests included Leakage Current Lightning Impulse and 50Hz Flashover. The results of all the tests confirmed the superb quality of the composite pole and throughout the process the structural integrity of the pole remained unaffected.

The results of the Ergon Energy tests are available from A.C. Whalan on request.

Corrosion is a by-product of our climate and Australia also has more than its fair share of termites.

Fortunately, and in the interests of keeping the power flowing, Aussie termites don’t like A.C. Whalan’s composite pole at all and for those indulgent creatures it’s a big turn off. The composite pole doesn’t suit their tastes and its ingredients include Vinyl Ester Resin, so it’s resistant to caustic alkalis and hypochlorite bleaching chemicals which also eliminates the potential for corrosion.

A.C. Whalan’s composite poles are environmentally friendly and there are no toxic preservatives used in the manufacturing process to leach out into the soil or ground water when the pole is installed.

Perhaps one of the most important benefits in a variable economic climate where money can be too tight to mention is that the dollars matter. Every dollar spent, particularly in the power and energy sector where poles and wires are critical, must achieve a greater return than the initial investment.

This is where A.C. Whalan’s composite poles really stand tall with a much longer life expectancy than your average timber pole and they are extremely cost effective.

The composite poles are manufactured from epoxy vinyl ester resins with UV Stabilisers added to the outside barrier of the pole. This is important as the use of UV Stabilisers preserves the life of the poles way beyond the life expectancy of traditional timber poles.

The A.C. Whalan composite poles based on US and European manufacturing data and related studies have a life expectancy of around 70 to 80 years.

so they are compatible with all current associated hardware such as cross arms and bolt-on foot pegs.

It means that timber pole networks can be gradually replaced by the composite pole over a period of time as existing fitments can be attached using similar methods as used for the traditional timber pole.

As for installation itself, the composite pole is much easier to handle being on average around 40% lighter than the equivalent rated timber pole. The erection methodology is very similar to the timber pole but due to its lightweight construction, where access is restricted or difficult due to the terrain, the composite pole is a much easier proposition.

Furthermore, smaller plant and equipment can be used in the installation process which leaves a much reduced work site footprint and reduces the impact on surrounding public areas. The ease of handling and installation minimises traffic disruption with less requirement for lengthy road or lane closures.

Due to its lighter weight, transport to the site is also far more cost effective and the composite poles can be stored and handled in much the same way as timber poles, other than the use of nylon straps to protect the surface of the pole instead of the traditional chains and dogs.

From its NSW base at Mt Thorley, A.C. Whalan manufactures composite utility poles in various configurations using the filament winding process.

The poles can be made as a 12.5 metre one piece or as a two piece to provide a variety of lengths for 9.5 metres up to a 28 metre configuration.

The production process provides a textured surface finish in grey but the poles can be coloured to suit the client’s requests.

A.C. Whalan Composites is an ISO 9001 accredited manufacturer and quality control is assured. The company uses state of the art Filament Winding machines with Siemens controllers in combination with CADWIND and with such finite accuracy A.C. Whalan can guarantee the quality and consistency of every pole produced in accordance with AS/NZZS 4676.2000 Structural Design Requirements for utility service poles.

Hardware & Fitment The composite pole is constructed from Vinyl Ester Resin giving it resistance to Caustic Alkalis, Hypochlorite Bleaching Chemicals and high temperatures and termites.

The Composite poles are manufactured in a cylindrical taper shape similar to the timber pole. This means that all current hardware such as cross arms & bolt on foot pegs and their fitment to the pole will be done the same way or using a similar method.

Cost Efficient Installation

Transport & Storage

The composite pole is installed in similar fashion to the timber pole, however, being lighter it is more cost effective to install in those applications with access restrictions.

Composite poles can be transported, stored & handled in the same way timber poles are, with consideration taken to protect the surface of the pole. This simply means nylon straps in place of chains & dogs. Because the composite poles are lighter in weight, transport costs become more efficient.

LiDAR lights the way for a safer power network State-of-the-art aerial surveys and high definition photography of Essential Energy’s electricity network have improved the quality of data collected as part of the company’s asset inspection program.

The LiDAR (Light Detection And Ranging) technology uses aircraft-mounted laser imaging to record the distance between powerlines and vegetation, the ground and structures – in conjunction with high-definition photography – to provide a detailed examination of the condition of pole top hardware.

Essential Energy Senior Engineer, Bradley Thomas, said the data captured by LiDAR, partnered with other software applications, provided the ability to model the exact nature of the network down to the position of powerlines in relation to the nearest tree.

“We soon realised this level of detail could be used in other parts of our business as well.

For example, network designers can use the 3D modelling and surrounding landscape details to improve their understanding of the network in relation to a specific area,” Bradley said.

“This means that many network issues can now be scoped from the desk, rather than requiring site visits.”

Datasets from the Office of Environment and Heritage provide terrain modelling, overlaying the map and location of the network to the use of the land underneath.

“This allows the business to prioritise public safety issues and helps us better manage risk and rectification,” Bradley said “LiDAR even enables us to overlay our data so supervisors can see the location of planned work, right down to the vegetation and any incline on the land. This enables them to dispatch the correct plant and crews for the job.”

Acting General Manager Asset Management, Paul Brazier, said Essential Energy had used LiDAR since 2014 as part of its asset inspection programs aimed at mitigating bushfire risk across its network.

“As new processes and technology become available, the uses of this information throughout the business will be leveraged in many different ways into the future,” Paul said.

Treasurer Curtis Pitt said Powerlink’s 45year-old Mudgeeraba Substation was one of two main supply hubs on the Gold Coast.

“This $25 million upgrade will improve the performance and reliability of Powerlink’s transmission network in the Gold Coast region, not only for the Games itself, but for many years to come,” Mr Pitt said.

“The Gold Coast Games will attract a global TV audience of 1.5 billion, so it’s important our key infrastructure is ready to help showcase the Gold Coast to the world.”

Energy Minister Mark Bailey said the upgrade would support local jobs.

“The $25 million investment will support up to 50 jobs in the local economy,” Mr Bailey said.

Essential Energy’s Regional Manager Southern, Steven Ilitch, said the substantial and complex project had been carefully planned to minimise the impact on local residents and businesses.

“The size of the project meant that we needed to source additional crew members from eight regional depots to complete the work in the shortest possible timeframe,” Steven said.

“About 78 field employees worked on the project and significant pre-planning and preparation was necessary to coordinate resources, schedule power outages and ensure that customers had been adequately communicated with about the project.

“A combination of high and low voltage alternative power generation was used throughout the project to provide crews with safe access to the network and minimise the impact on customers.”

Completed in late April, the project included the upgrade of power poles and powerlines south of Kamarah and installation of remotelyoperated gas switches with fault indicators on the main 33kV powerline to improve network isolation capabilities and fault and emergency response times.

“This is the lowest cost option for consumers that will extend the life of the substation for many years.

“Rather than undertake a major replacement Powerlink will upgrade specific parts to further extend the life of the existing substation.

“This investment approach is focused on keeping long-run transmission costs as low as possible.

“Importantly, all works have been planned to avoid any disruptions to supply.”

Powerlink Queensland Chief Executive Merryn York said substation system designs and standards had changed significantly since the early 1970s and would continue to improve.

“We want to play our part in GC2018, so the focus of the work will be on replacing the systems which allow us to better manage our network in this region,” Ms York said.

“These systems are critical to operating and monitoring our assets and responding rapidly to any unexpected issues that may arise.”

The upgrades include primary and secondary systems, a new transformer, new fencing, a new control building and minor works.

Some redundant equipment will be decommissioned.

Temporary diesel generation at Hydro Tasmania Power Stations

B

ETWEEN January and May 2016, we installed more than 220MW of temporary diesel generation at Hydro Tasmania power stations, TasNetworks substations and industrial sites.

Temporary diesel generation installations throughout the state have been subject to approval by the Environment Protection Agency (EPA). More detail on the EPA approval for each site can be viewed at www.epa.tas.gov.au

Due to recent rainfall and associated inflows into hydro storages, diesel generation has not been used since early May. The smaller storages and ‘run of river’ schemes have been generating to maximise use of available water in the system, and avoid spilling water.

Hydro Tasmania will continue to prioritise the rebuilding of storages.

Hydro Tasmania has started the first phase of demobilising the temporary diesel generators.

Four sites will be demobilised in June and July, reducing diesel generation capacity from 222MW to 135MW, and saving about $2 million per month in lease costs.

The four sites being decommissioned in June and July are: • Catagunya Power Station; • Meadowbank Power Station; • George Town substation; and • Port Latta substation.

The total capacity to be demobilised is 87 MW, leaving approximately 135 MW remaining at the Que River and Bell Bay sites available to operate if required. Hydro Tasmania will continue to monitor the situation and further judgements will be made about the balance of the diesel generation in the coming weeks.

Overview of recent low energy supply situation and current status The record low rainfall between September 2015 and April 2016 and the extended fault in the Basslink interconnector were both very rare events, the combination of which has not previously been experienced in Tasmania.

Given uncertainty about the Basslink return to service date, Hydro Tasmania enacted plans to meet all Tasmanian energy demand through to the winter rains without Basslink in operation, even in the event of low inflows and so that we were able to cope with another substantial event.

Hydro Tasmania considered this approach to be prudent while uncertainty over future inflows and on the timing of a repair of Basslink remained high. May 2016 was the wettest May on record in terms of inflows into Hydro storages – about 250 per cent of the long-term average. Some Hydro Tasmania catchments also received unprecedented inflows during extremely heavy rain in early June. Hydro Tasmania’s priority is to continue to rebuild storages through winter and spring with the

Above: Lake Cathana on spill focus on Lake Gordon, Great Lake and Lake Echo, as other storages are currently well above target level. The Basslink interconnector was returned to service on 13 June 2016. With many hydro storages close to full, or spilling, Hydro Tasmania will use the interconnector to

export energy that is in excess of Tasmanian demand. Gas generation in Tasmania is being used, if required, to meet peak demand. No diesel generation has occurred since early May and Hydro Tasmania has begun the process of decommissioning diesel generation.

EPSA Supplies Temporary Power to Tasmania

E

NERGY Power Systems Australia (EPSA) is currently working with Hydro Tasmania and the Australian Energy Market Operator (AEMO) to safely connect temporary Cat® diesel generation to ensure the Tasmanian power network continues to operate safely and reliably.

Record low rainfall and a positive Indian Ocean dipole are both very rare events and, coupled with an extended fault in the Basslink interconnector, has resulted in a low energy supply situation in Tasmania.

“This combination of very rare events has seen unprecedented power challenges for Tasmania and we are working with Hydro Tasmania to provide a safe and reliable network for all Tasmanians,” said EPSA’s Managing Director, Phil Canning.

At the time of writing, Hydro Tasmania, TasNetworks and others across the state government are delivering a plan that will have up to 100 MW of temporary diesel generation available for operation.

Sixteen Cat® generators, 22 kV transformers and ancillary equipment are installed in Georgetown. The first 15 MW base load power station has been deployed and a further 19 generators, transformers and ancillary equipment are in Port Latta. A second 15 MW base load power station was installed in March.

The new custom solutions-built Cat generators are designed for fuel efficiency, performance and reliability and deliver value for money. William Adams, the local Cat dealer, will be providing Cat-trained technicians from Launceston and Burnie to assist EPSA in undertaking the required scheduled servicing maintenance activities.

“This is another great example of our ability to respond immediately to deliver a tailored power solution in emergency situations, utilising the Cat partnership between EPSA and William Adams,” said Dale Elphinstone, Chairman, William Adams.

“The ability to deliver, install and service Cat generators quickly and efficiently is a testament to our effective partnership.”

Aggreko played a major role in alleviating Tasmania’s power crisis

A

GGREKO, the world-leading supplier of temporary power solutions, is currently playing a major role in the mitigation of the power crisis currently affecting Tasmania.

The crisis had been sparked by the failure of the Basslink cable running between Tasmania and Victoria on December 20 last year and the ongoing drought which had meant that power utility Hydro Tasmania had been faced with falling water levels at its various storages which fell to an average of 9% of capacity and compromised its power generation capacity.

Company MD George Whyte said that the State Government and Hydro Tasmania had taken the necessary step of implementing

a $44-million Energy Supply Plan which brought Aggreko and other suppliers aboard to provide enough temporary power generation capacity to make good any shortfall. It is anticipated that the plan will operate until such time as the Basslink cable comes back online and the water levels in Hydro Tasmania’s storages are normalised.

The state’s simultaneously reduced power supply and generation capacity had been viewed in an especially serious light due to the approach of winter and the anticipated rise in power demand.

Mr Whyte said that while the company was the world leader in temporary power solutions even it had faced major logistic challenges in assembling the generator fleet required to produce power on the scale required by the

customer. The expertise of the Aggreko team and the resources the company has available around the globe made it possible to deliver and install over 100 generators within a very short timeframe.

improved water levels in the Hydro Tasmania storages mean that the generator fleet is now mostly on standby and only brought online where demand rises above the utility’s generating capacity.

The generator fleet deployed in Tasmania

by Aggreko consists largely of the 1250kVA containerised units and a number of smaller units located at Hydro Tasmania’s sites at Meadowbank, Catagunya and Que River.

The Meadowbank and Catagunya sites each boast 24MW of emergency power while the site at Que River consists of 60MW.

The company can provide generators fuelled by diesel, gas or both but the fleet deployed in Tasmania is diesel-powered with Aggreko providing the on-site fuel storage tanks and Hydro Tasmania being responsible for the provision of fuel. Skilled Aggreko personnel are on hand at each site on a 24x7 basis to operate and maintain their generators and ensure they are available to the client whenever required.

Running at their peak the Aggreko generators are capable of feeding 108MW of electricity into the Tasmanian power grid but according to Mr Whyte, recent rains and

Power shortages and disruptions are a major threat to commerce and industry and hugely inconvenient to the public at large. It has been estimated that they are responsible for the loss of US$80-billion every year in the US alone and that losses around the world are much greater than that.

There are many reasons why power shortages occur but Aggreko’s temporary power projects are a cost-effective solution which can be tailored to the client’ exact requirements and provide power for as long as needed. Clients can be any organisation requiring power on a temporary basis and range from large utilities to industrial concerns.

Power Projects can be tailored to generate baseload power to supplement the grid and overcome generation capacity constraints, to overcome transmission and distribution constraints and to provide power during the scheduled maintenance of power equipment.

Services provided by Aggreko include all aspects of the design of the power package, fuel options, mobilisation, site preparation, commissioning, configuration, maintenance and operation.

New Darwin Zone Substation project complete

P

OWER and Water’s new Darwin Zone Substation is complete and fully commissioned.

The $40 million substation project is part of Power and Water’s major infrastructure investment program and replaces the City Zone Substation, which has reached the end of its operational life.

The project, which commenced in 2013, sees the continued use of Indoor 66kV Gas Insulated Switchgear addressing the severe environmental impacts the top end region experiences. The new substation has all high voltage switchgear housed indoors ensuring a protected environment from dust and extreme weather, greater security and a more clean-cut amenity located in the Central Business District (CBD) of Darwin.

The substation, transforms the 66kV power to 11kV before being distributed to customers in the CBD and surrounding areas and is expected to have at least a 50 year lifespan. Along with support from the Frances Bay Zone Substation this will provide an improved level of reliability and security of electricity supply to the CBD of Darwin.

Minister for Essential Services, Peter Chandler officially opened the Darwin Zone Substation on 11 April.

Power and Water has been working systematically to improve network infrastructure and continue providing reliable essential services across the Territory.

Territorian’s powered by new Darwin Substation

A

new $40 million substation has been opened in Darwin City recently to meet the future demands of the Territory.

Northern Territory’s harsh, local environmental conditions.

“The Northern Territory Government is focused on the need to upgrade and replace older zone substations and build new ones to support growing customer load,” Mr Chandler said.

“The new substation is the largest in the Territory’s power system and feeds Darwin

CBD and surrounding areas, improving the reliability and security of electricity supply.

“Substations are an important part of the power network and it is here that high voltage power is transformed to low voltage power that supplies customers.”

The scope of works included the design and installation of the substation building to house new switchgear and controls and three new

power transformers.

“The Northern Territory Government has a plan to build the infrastructure the Territory needs now and into the future,” Mr Chandler said.

“We are delivering on better services and lower costs in the power industry to ensure reliable power supply and affordable living for Territorians.”

Minister for Essential Services Peter Chandler (above) officially opened the Darwin Zone Substation that was built to replace the City Zone Substation which has reached the end of its economic life.

“Darwin has grown significantly in recent years and the Northern Territory Government is committed to meeting the demand from the residential, business and industrial communities,” Mr Chandler said.

“With a new and modern design, equipment is housed indoors and is no longer exposed to outdoor environmental factors.

“Direct lightning strikes, high winds with the potential of debris impacting structures and exposure to animals such as bats or snakes can cause significant interruptions to power supply.”

The new substation comprises of indoor 66kV Gas Insulated Switchgear (GIS) as opposed to the existing outdoor 66kV switchyard. The 66kV GIS is proven technology that addresses the

Transmission Tower Earthing Earth Resistance of Transmission Towers Transmission towers are solidly earthed at the base either directly by the buried leg structure or more commonly via a radial earthing strip.

Additionally an overhead earthing conductor is placed above the live conductors bonding each tower of the transmission line to the earth grid at the origin and destination switchyards.

voltage between the tower

Transmission Line Earthing Because of their height and location, transmission towers are extremely vulnerable to lightning strikes. When lightning strikes a tower or the overhead earth wire the current is safely dissipated to ground via all the towers bonded to the overhead earth BUT only if the earthing system is in good condition!

What Can Go Wrong?

When transmission lines are constructed they are expected to be in service for many years. Towers are frequently in remote areas and while out of sight should not be out of mind.

Steel is used for construction and although hot-dipped galvanised, corrosion can eventually occur, particularly if near the coast and often below ground level.

The overhead earth wire bond at the top of the tower can corrode. The radial earthing strip can corrode in certain types of soil and if of copper is a magnet to thieves who can

take advantage of remoteness to dig up the copper with little chance of detection.

All these factors can contribute to a deterioration in the effective earthing of the transmission line and its ability to dissipate lightning strikes.

Testing Transmission Tower Earthing Because a transmission tower typically has four legs and is, or should be, bonded to the other towers, it is not possible to measure the earth resistance by conventional methods.

If a conventional earth tester is connected to the tower it will only measure the effective earth resistance of the complete line including the switchyard grids at either end.

It might be argued that provided the result

provided. But this gives no indication if all, some or none of the towers are contributing to the effective earthing of the line.

It is possible that the switchyard grids at either end are the only effective earth for the

entire line! In this scenario a lightning strike could travel the complete length of the line before being dissipated.

Conventional Earth Testers Unsuitable If a conventional earth tester is used to measure the earth resistance on an individual tower, it requires each tower to be climbed, the earth bond isolated, the resistance measured and the earth wire reconnected.

Testing an entire transmission line by this method would be a lengthy and costly project not to mention the WHS issues and access permits required particularly if the line is in service.

accurate measurement. The higher the test current, the better but for convenience and ease of portability into often rough terrain, the current needs to be supplied from light weight batteries. A 250mA test current is a good compromise between measurement accuracy and portability.

Measuring the current in tower legs was originally attempted with a large split iron-core CT with limited success because " &

legs, between 4 and 12 measurements had to be manually summated as parallel resistances and the CT was heavy, brittle and expensive.

Rogowski Coils to the Rescue Cost Effective Alternative Measuring the earth resistance of a tower in-service without disconnecting the overhead earth wire is achieved with the injection of an off-mains-frequency test current into the tower structure. "

The problem was solved by using four 5-metre Rogowski Coils.

The AEMC GroundFlex The AEMC 6472/6474 GroundFlex kit is the perfect solution for complete earth testing requirements.

The 6472 (available separately) is a stand-alone multi-function earth tester which performs soil resistivity (without calculating it from a resistance measurement), earth resistance, leakage current and step potential measurements.

In earth resistance mode the 6472 measures both isolated and in-service earth grid resistance by either the selective or stakeless methods.

When coupled to the 6474, the selective method is extended from a single clamp to four Rogowski coils for measuring the earth resistance of poles and towers with up to four legs.

Once set up, the GroundFlex will measure the earth resistance of a tower in seconds!

Assets go under to protect power above

E

SSENTIAL ENERGY has relocated zone substation infrastructure underground at Moree in a major multistage network project designed to secure a more stable and flexible electricity supply for the local area into the future.

Project Manager Major Projects, Glenn Potter, said the planning and strategic resourcing of the $3.2 million project had been critical to ensuring power supply disruptions were minimised while work was completed.

“We had a number of industrial customers operating nearby who would be impacted by supply outages, so we organised to carefully reroute power through the remaining feeders and use live line techniques where possible,” Glenn said.

The improvement project also involved replacing the zone substation with a new control

building and installation of a 22,000 volt panel switchboard, ten high voltage circuit breakers, protection relays and more than one kilometre of underground aluminium cable.

“The upgrade will help to protect the zone substation against weather-related power outages with most of the infrastructure moved underground,” Glenn said.

“The new switchboard provides improved safety and flexibility for network operators at Essential Energy’s system control centre to reroute power in the event of a network fault and minimise outages.”

More than 5,700 households and businesses in the Moree, Biniguy, Bullarah, Crooble, Gurley, Milguy, Millie, Pallamallawa, Terry Hie Hie, Yarraman and surrounding areas have benefited from the upgrade.

Replacement zone substation for Maitland, NSW

A

major project to replace ageing electrical equipment at the Ausgrid substation supplying parts of Maitland in the Hunter Valley is entering its final stages.

A new zone substation was commissioned in 2013 to help maintain a safe and reliable power supply to more than 6,000 local homes and businesses.

The facility replaces the old Maitland Central zone substation which was commissioned in 1977.

Above: Maitland in 1977 Page 16 - Australian Power & Energy News

The substation’s original transformers installed almost 40 years ago - were recently removed from the old substation building.

This will allow the old control building to be demolished so a transformer runway can be completed for maintenance vehicles to access the new substation.

The old transformers have been sent to Sydney for refurbishment and reuse in Ausgrid’s Leightonfield Zone Substation.

$20 million investment in Central Queensland electricity hub

A

$20 million investment in Powerlink Queensland’s transmission network in Central Queensland is set to further secure electricity supply to the region and support continued economic growth.

The project involves an overhaul of systems and equipment at Powerlink’s Calvale Substation, near Biloela, which is a vital hub in the high voltage network transporting power from Callide Power Station across the network to Gladstone and other parts of the State.

Powerlink Chief Executive Merryn York said this major investment will support growth in one of the key drivers of the Queensland economy.

“Powerlink plays an important role in powering the Queensland economy, being responsible for the reliable supply of electricity to industry across the state,” Ms York said.

“The $20 million investment will support economic growth in this region, as well as support 50 jobs.

“The work will also further improve the performance and reliability of the high voltage network in Central Queensland.

“The Gladstone region is one of Queensland’s major export gateways and home to two of the world’s largest alumina refineries.

“This important work ensures continued system security and reliability to this major industrial hub and the wider Central Queensland area.”

Ms York said the work would extend the life of the existing Calvale Substation to around 2033 and will also improve the ability to respond to network issues.

“The focus of the work will be on replacing the systems which allow us to manage our network in this region remotely,” Ms York said.

Submissions sought on new approach to power planning

W

ESTERN Power is seeking expressions of interest from businesses and community groups who may be able to provide non-network solutions to manage electricity demand in the Mandurah region, south of metropolitan Perth.

The Mandurah load area has one of the highest rates of population growth in the country and over the next five years demand is forecast to place pressure on electricity infrastructure in the region.

Western Power’s Executive Manager Asset Management Seán Mc Goldrick said more than $30 million of network investment would be required by 2020/21 under current design protocols to meet demand.

“Our current forecasts show a steady increase in electricity demand as the Mandurah region continues to grow and normally Western Power would install extra network capacity to keep pace with that demand,” Mr Mc Goldrick said.

“However, non-network solutions, such as communities better managing or reducing energy consumption or that involve solar systems and battery storage, may be more cost

efficient and provide greater flexibility over the long-term.”

Mr Mc Goldrick said the challenge of meeting a community’s power needs was no longer a job for a central planning group.

Where historically, the power system had been planned by utilities, such as Western Power, increasingly communities and individual electricity consumers were having a say in how and where they will access their energy.

“These days, meeting demand for power is a collaborative effort that involves the entire community,” he said. “We can’t just install new transformers, larger poles and longer wires, and expect our customers will be happy for them to possibly sit idle.

“We are embracing opportunities, such as which exists in the Mandurah region, to test alternative methods and technologies to reduce peak demand and provide more cost effective ways to deliver electricity to our customers.”

Expressions of interest are open until 12 August 2016. For more information, please download the report, Mandurah Load Area: Non-Network Options Report, from our website www.westernpower.com.au or email nonnetwork@westernpower.com.au

Above: Calvale Substation “These systems are critical to monitoring and operating our assets if a fault occurs and responding to any issues in a timely manner.”

Works have been scheduled to align with maintenance work at the Callide Power Station to ensure there are no supply impacts to consumers or customers directly connected to the transmission network.

Changes to ActewAGL’s natural gas and electricity prices

F

ROM 1 July 2016 ActewAGL’s natural gas and electricity prices in the ACT will change.

ActewAGL will reduce its natural gas retail prices in the ACT. This change will mean a decrease of around $105 a year on the total gas bill for a typical Canberra home who uses 43GJ per year. This includes a full pass through of gas network cost reductions as per the Australian Energy Regulator’s decision on 26 May 2016.

In addition, the Independent Competition and Regulatory Commission (ICRC) has today announced that electricity prices in the ACT will rise. This means an increase of around $100 a year for a typical Canberra home that consumes 8,000 kWh per year. This change is primarily due to an increase in costs incurred

by ActewAGL for the purchase of wholesale energy and compliance with the Australian Government’s Renewable Energy Target scheme.

In response to today’s electricity and gas pricing decisions, ActewAGL General Manager

Ayesha Razzaq said, “For our electricity and gas customers these changes will have a minimal impact. For our customers who have electricity only, we will continue to help them manage their bills through a variety of support programs. These include our free Energy Saving House Calls where customers can save up to $221† per year by moving to more energy efficient products.

“ActewAGL also has a number of flexible payment options to assist our customers. Many customers choose, for example, to have regular, smaller payments deducted from their accounts to manage their household budgets. We can also tailor affordable payment plans for customers who are experiencing difficulty paying their bill.

“In addition to remaining competitive on price, we will continue to deliver value to our customers through our local call centre and strong support for our community.”

Granny Smith Gold Mine gets greener state-of-the-art energy supply G

OLD FIELDS’ Granny Smith Gold Mine is now supplied by the world’s most efficient high speed reciprocating1 engine power station of its class, which was designed and delivered by Aggreko.

During the official opening ceremony of the power station, Gold Fields Executive Vice President Richard Weston said that the Granny Smith Gold Mine, south west of Laverton on the Goldfields, has become the latest of its mining operations to source electricity from a gas-power station.

“The official opening has marked a significant milestone for the Granny Smith Gold Mine and a major achievement for Gold Fields as a company which now operates all four of its Western Australian gold mining facilities by using gas-powered generators rather than diesel generators,” Mr Weston said.

“Gold Fields has a long standing vision to be a global leader in sustainable mining and our major investment in the gas-powered technology designed, built and operated by Aggreko demonstrates our forward thinking and commitment to finding better ways to excavate and process one of the world’s most precious substances – gold.

“Gold Fields identified a major opportunity to utilise gas supplied from AngloGold Ashanti and APA Group’s Eastern Goldfields gas pipeline and upgrade their 25-year-old power station which was nearing the end of its useful life,” he said.

Mr Weston said that in addition to the cost efficiency and reliability benefits of the new gaspower station, it would reduce carbon dioxide (CO2) emissions by 85,845 tonnes during the ten-year contract with Aggreko.

“The Granny Smith Gold Mine is operating greener which makes it eligible for the Australian Emissions Reduction Fund,” Mr Weston said.

Aggreko Managing Director George Whyte said that the Granny Smith Gold Mine power station is one of the most technologically advanced modular systems in the world.

“Our mining clients have faced a challenging market place and power generation is a significant proportion of operating costs. Our global capability offers additional flexibility which reduces investment and operational risk,” Mr Whyte said.

“Aggreko’s focus is on fuel efficiency and reliability in line with the power demand over the life of the mine.

“A tremendous amount of ingenuity has gone into the development and evolution of Aggreko ‘Next Generation Gas’ generators to deliver a 24 mega watt (MW) power generating system for the Granny Smith Gold Mine.

“The new 33 kilovolts (kV) distribution system will meet the daily power needs of the entire mine of 24MW with 8MW allocated to the Wallaby underground mine and the remaining 16MW for the processing plant, associated facilities and camp.

“Other design features include high pressure gas conditioning infrastructure with heat recovery technology. This optimises power station efficiency and reduces gas pressure from the Easter Goldfield’s Gas Network,” he said.

Mr Weston said the investment Gold Fields has made at its Granny Smith Gold Mine will assist in extending the life of the operation which has secured direct and indirect employment in the Goldfields region and will continue to generate major investment for the Australian economy.

“Granny Smith Gold Mine produced approximately 300,000 ounces of gold during 2015.

“Gold Fields and Aggreko have delivered a power station that will supply Granny Smith Gold Mine with safe, affordable and reliable electricity and allow for future expansion,” Mr Weston said.

ActewAGL donates $100,000 of equipment to restore electricity in Fiji

A

ctewAGL has donated $100,000 of specialist equipment to help rebuild Fiji’s electricity network after it was devastated by Tropical Cyclone Winston in February.

ActewAGL’s contribution forms a significant part of the $270,000 total, which energy network organisations across Australia donated.

The funds have been used to purchase essential specialist tools and equipment including electrical test equipment, hydraulic cutting tools, drills and pole saws for cutting trees and other vegetation. ActewAGL has also coordinated the equipment purchases on behalf of the Energy Networks Association (ENA).

In addition, energy network organisations have donated seven heavy vehicles including elevated work platforms, crane borers and a service truck to the value of $130,000.

Providing this equipment will significantly reduce the restoration timeframe as workers are currently sharing equipment between teams in some cases up to 10km away from each other.

The restoration work will also improve the

resilience of Fiji’s electricity network should future disasters occur.

ActewAGL Chief Executive Officer Michael Costello said, “Fiji’s electricity network suffered tremendous damage from Cyclone Winston with more than 4,500 electricity poles to be replaced across the country. It is an arduous time for the people of Fiji as they recover from this disaster and ActewAGL wanted to do what we could to help rebuild the electricity network.”

ActewAGL is proud to be part of this combined energy networks initiative and would like to acknowledge the Australian Government and ENA for their leadership in coordinating the restoration effort.

An assessment team commissioned by the Australian Department of Foreign Affairs and Trade estimates that productivity will increase by up to 25 per cent when the teams are fully equipped with all necessary equipment.

At the end of the restoration the equipment will be donated to the Fiji Electricity Authority to continue work on initiatives to reduce the disaster risk in the future.

AusNet Services launches groundbreaking community mini grid trial

A

USTRALIA’s first mini grid trial in an established community was launched in the Melbourne suburb of Mooroolbark recently by Victorian Energy Minister Hon. Lily D’Ambrosio MP and AusNet Services Managing Director, Nino Ficca.

The trial is being undertaken to demonstrate that 14 homes with residential solar systems and batteries can generate, store and share renewable electricity with each other as a ‘mini grid’ via their local powerlines.

AusNet Services MD, Nino Ficca, said that it’s an exciting trial and thanked the residents for their willingness to participate.

“We’re now installing the solar systems, batteries and associated communication equipment and greatly appreciate the readiness of this community to take part in this groundbreaking trial,” Mr Ficca said.

“AusNet Services is excited to partner with the community to develop systems that may give consumers the choice to share their solargenerated electricity with their communities, potentially lower their bills and support the electricity network,” he said.

Over the next 12 months, AusNet Services will focus on monitoring consumption levels

and behaviours for each participating household so that individual houses can be disconnected from the electricity grid, operating solely on the solar energy generated and stored in their batteries.

The final stage of the trial will use AusNet Services’ control system to share stored renewable electricity between the homes in the street as a genuine ‘mini grid’ system.

“We’ve developed a control system that will monitor and manage energy flows within the mini grid. This system will enable the energy that is stored in batteries to be shared between houses, based on the needs of the individual houses, the diversity of customer loads within the mini grid and the needs of the network,” Mr Ficca said.

“This project builds upon the learnings gained from a residential battery trial we recently completed, which identified benefits for both consumers and electricity networks, and the need to find ways for both parties to work together to realise these benefits,” he said.

AusNet Services’ three-year battery storage trial tested how residential batteries can export electricity into the grid to support the network during peak demand times, during unplanned outages, such as storm events, and as a solution that may delay or offset network investment.
