Entura helping the Cook Islands on their renewable energy journey

S

PECIALIST power and water consulting firm Entura is helping the Cook Islands reduce reliance on diesel fuel, as part of the country’s goal to use renewable energy on all islands by 2020.

The Cook Islands is a group of 15 small islands in the Pacific, to the north-east of New Zealand.

Entura will develop preliminary designs for remote area power systems in six islands, and assist the Cook Islands Government in their implementation.

“Energy security and self-sufficiency are essential for remote islands such as Rarotonga, the most populous of the Cook Islands,” said Entura’s Managing Director, Tammy Chu. “Diesel fuel remains the single largest expense to generate power in these remote locations, so using renewable energy makes good economic sense.”

Climate change poses a particular risk to the Cook Islands due to sea level rise, extreme rainfall events, storm surges, strong winds and extreme high air temperatures. These changes are expected to adversely affect marine and terrestrial environments, giving rise to issues for food security, water resources and biodiversity.

“The commitment to renewable energy is a fundamental prerequisite to sustainable development,” said Richard Neves, Financial Secretary from the Cook Islands Ministry of Finance and Economic Development.

“It also underlines the Government’s commitment to addressing climate change, preserving the country’s pristine environment

Above: Entura’s project team with Tangi Tereapii (Cook Islands government) visiting solar sites in the Cook Islands and ecosystems, and also strengthening the level of energy security and therefore sustainable economic growth.”

Entura will assess the technical, environmental, social and economic viability

of a transition from diesel to renewables, and make recommendations to the government of the Cook Islands and the Asia Development Bank on the optimum solutions to achieve the project objectives.

In the first phase of the project, the islands of Atiu, Mitiaro, Mangaia and Mauke will be converted from diesel power supply to a solarbattery hybrid system that will supply close to 100% of their energy needs, with diesel as a backup.

The second phase will focus on the islands of Aitutaki and Rarotonga, which have higher power demands. Power systems there will be

upgraded to increase levels of renewable energy penetration, and integrate grid stabilisation technology to pave the way for installation of further generation.

As well, Entura will deliver strategic advice to assist with energy policy development for the Cook Islands, and develop practical training for local operations and maintenance workers to enhance their ability to manage the day-today operation of renewable energy systems both now and into the future. Institutional strengthening is a key output of the project.

The three-year project is expected to be completed in late 2018.

Forum attendees were given an overview of Powerlink’s Transmission Annual Planning Report (TAPR), providing an insight into future energy and demand forecasts, network development and transmission projects.

Powerlink Queensland Chief Executive Merryn York said growth in energy and demand over the next 10 years would be relatively flat.

“The TAPR indicates that summer maximum demand is forecast to increase at an average rate of 0.9% per annum over the next 10 years,” Ms York said.

“The LNG industry continues to be a strong contributor to forecast growth. Without the impact of LNG, forecast demand would increase at an average of 0.2% per annum.

“This is the first year we have made our energy and demand forecasting model publicly available. We wanted to make our model as transparent as possible so stakeholders could clearly see the inputs we have used in our forecasts to better inform their decision making.”

The forum adopted a new format, with the TAPR presentation followed by concurrent breakout sessions covering key topics of interest that Powerlink was seeking input on.

“Powerlink recognises the importance of engaging with our customers, consumers and

industry representatives to ensure we continue to deliver a valued service,” Ms York said.

“The forum brought together some of our most important stakeholders, so we thought it would be a great opportunity to get their input on key areas of our business.

“The three breakout sessions involved interactive discussions on our upcoming Revenue Proposal to the regulator, optimising our network planning and how we can best consider new technology in our energy and demand forecasts.

“We received great feedback that will improve our decision-making and ensure we continue to provide a safe, cost effective and reliable supply of electricity across Queensland.”

Three new circuit 132kV breakers now in service

P

A

OWER and Water Corporation’s 2015 major equipment upgrade for the Hudson Creek Switchyard is complete with the third 132kV circuit breaker now energised and in service announced Power Networks’ General Manager John Greenwood.

“These works are the second stage of a long term, wider network upgrades’ plan that commenced in 2014.

“The plan is designed to improve the security and reliability of the 132kV power network.

“Following the success of last year’s works, installation of the three circuit breakers was completed well ahead of schedule and without the need to implement our contingency plans,” he said.

The process of installing new circuit breakers is challenging and presents considerable risks to the system.

“Power and Water’s Power Networks and System Control and Territory Generation worked together on a meticulous and methodical planning process, which ensured the project was implemented quickly and efficiently and without disruptions to customers throughout the complex installation process,” Mr Greenwood said.

Stage 2 - 132kV circuit breaker replacement project at the Hudson Creek Switchyard took place from June to July 2015. Three circuit breakers were replaced in 2014 (Stage 1). Stage 2 works replaced the remaining three circuit breakers. As with Stage 1, works were scheduled during the dry season, when demand on the power system is at its lowest, making it the optimal time to de-energise the transmission line to perform these works with minimal risk of power interruptions. The replacement works are designed to improve the reliability of the network and increase operational flexibility.

Power and Water remains dedicated to improving infrastructure and delivering safe, efficient and reliable utilities services for Territorians.

Power and Water’s Power Networks’ program of intensive maintenance and upgrades in the Darwin region will continue in 2016.

North Shore cable upgrade restoration underway USGRID crews are completing final restoration of trenched areas after installing 132,000 volt underground cables as part of the East Lindfield to Artarmon section of the North Shore cable replacement project. The Sydney-based project involves replacing cables in the area that were installed about 40 years ago, along two routes - between East Lindfield and Artarmon, and East Lindfield and Castle Cove.

Above: Installation of the circuit breaker replacement work and below the completed work

Ausgrid Deputy Chief Executive Officer Trevor Armstrong said the cables needed to be replaced before they became unreliable.

“Ausgrid worked closely with the community throughout this project and feedback was incorporated into the final design,” Mr Armstrong said.

Newsletters have been provided at each project stage to about 10,000 homes and businesses and we held a number of information sessions and onsite visits. Residents and businesses have also continued to receive regular notifications ahead of work in their area.

“Working through suburban areas is a challenge and we know our work can be disruptive. We strive to show the upmost respect for our customers when working through their neighbourhoods by letting them know we are coming and what the work will involve.”

Recognising the impact this type of trenching work has on the local community and people who travel through the area, the final restoration of roads was prioritised. This meant, busy thoroughfares like Archbold Road were permanently restored as soon as possible with the rest of the streets along the Lindfield to Artarmon route progressively being permanently reinstated.

With cable work complete on the East Lindfield to Artarmon route, crews are focussing their work to join sections of cables in three remaining locations on the East Lindfield to Castle Cove route.

It is expected all major work and road restoration across the two cable routes will be completed by November.

Metford zone substation set to power up

USGRID crews are putting the final touches on the new Metford zone substation in New South Wales lower Hunter Valley.

The 33/11kV substation has been fitted out with two transformers and space for a third, as the potential for growth in the immediate area is significant.

Above: Crews working on the 33kV cables in the basement of the substation Page 4 - Australian Power & Energy News

Crews have installed two transformers and the electrical switchgear at the new Metford zone substation, which will help safely supply electricity to about 8,000 local homes and businesses The substation has been designed to fit in with the surrounding neighbourhood while still achieving an economic and efficient solution to meet the requirements of the network, and will safely supply about 8000 homes and businesses when it is commissioned in August.

“The new Metford zone substation will allow the nearby East Maitland zone substation to be shut down after almost 50 years of service,” Ausgrid Deputy Chief Executive Officer Trevor Armstrong said.

“The recently completed Maitland Central zone substation replaced equipment installed in the 1970s, and these two projects together will help provide a safe and reliable power supply in the area for years to come.”

The Metford zone substation is an indoor outdoor design with connections to the 33kV network via existing overhead infrastructure nearby and all the 11kV cables connecting to the existing underground network.

Homebush to Rozelle cable replacement progressing well

C

ABLE replacement work between Sydney suburbs Homebush and Rozelle is progressing well with trenching work well underway.

The new underground 132,000 volt cables replace 50 year old equipment running about 14 kilometres between subtransmission substations in Homebush and Rozelle, via Leichardt and Croydon substations in Sydney’s inner west.

Crews have completed trenching work within Leichhardt LGA and Ausgrid Deputy Chief Executive Officer said the first stage of construction involved tunnelling underneath a canal behind Ausgrid’s Croydon zone substation.

“The existing underground transmission cables were installed in the 1960s in the area and are now due for retirement,” Mr Armstrong said.

“Replacing these old cables will help maintain a safe and reliable electricity supply to customers across Sydney’s inner west.”

The project team has been working to minimise impacts on the community by completing work near schools in the holiday periods and planning to complete crossing in parks when work would have the least impact on users.

Ausgrid and its contractors are attempting to minimise any inconvenience and are committed to keeping customers informed about the progress of these works so they can plan accordingly.

Sydney Olympic Park Substation civil work complete

C

IVIL work at the new Sydney Olympic Park substation is complete and Ausgrid crews are working on the electrical fit out, with room for three 50 MVA transformers, seven panels of gas-insulated switchgear and about 25 11KV circuit breakers.

Ausgrid Deputy Chief Executive Officer Trevor Armstrong said the substation is expected to be powering parts of the local area mid next year.

“Sydney Olympic Park is a growing business and residential community, and the new substation will help meet the increasing demand for energy and is in line with the area’s Master Plan,” Mr Armstrong said.

The design of the substation was created with significant input from the Sydney Olympic Park Authority, including the selection of its location in Bicentennial Park and both organisations are working together to complete the final landscaping around the substation.

New conduits and cable have been installed to connect the new substation to the electricity network.

They run about one kilometre between a subtransmission substation at Mason Park and the new substation.

Test Line takes the time out of ‘Cable Fault Finding’

A

S we know, no matter what business you’re in, time is money and when your business grinds to halt due to an ‘electrical cable fault’ it’s critical that the resulting downtime is minimised. Speed is of the essence when locating and repairing a cable fault so that your profitability is restored as quickly as possible.

Michael Pratt is the owner of Test Line and he’s no stranger when it comes to finding the source of an electrical cable fault. As a qualified electrician it’s been his business for more than twenty years and he’s seen it all, from faults in 240V domestic installations to 33,000V distribution cables.

The Test Line team have located thousands of cable faults, commissioned High Voltage installations and repaired cables at power utilities, mines, refineries, development sites, factories, farms, homes and in just about any location you can think of throughout industry and the private sector.

Above: Michael Pratt with pipe and cable location equipment

Above: Crews receiving and installing the transformers at the new Sydney Olympic Park substation

Michael’s philosophy is simple.

“We pride ourselves on finding the fault as fast as we can, and value being spot on every time. Once located our next aim is to minimise disruption and finding a solution to repair the fault.

“The success of our business is based on our reputation for applying cost effective solutions both in fault finding and our experience in what is needed for the repairs. Minimising downtime is our strength. We like a challenge and we like to be tested.”

Test Line uses a Surge Generator and Listening set to get right on top of the fault, T.D.R. Scopes give distance and length and with the frequency generator they are able to accurately determine the route and depth of the cable (or pipe).

The team also utilises the A-Frame method when searching for ‘ground faults’.

Results are enhanced by the team’s ability to professionally analyse the results and to pin point precisely the position to the metre of the fault.

The Test Line team is XLPE and PILC (paper insulated lead cable) qualified, and are proficient at Proof Testing cables for acceptance, VLF or DC. Test Line also performs infrared scanning using a FLIR camera and can report dangerous “Hot Spots” at switches, motors or any other electrical connection or friction area.

Test Line’s operational reach extends throughout Queensland and Northern NSW.

Highway and Cooper Street, with a modern substation that has been constructed on adjoining land. New 132,000 volt cables have been laid to supply power to the new substation.

Engadine substation project Construction of the substation buildings has been completed and installation of the electrical equipment is underway. Commissioning of the

new substation is due to occur in mid 2015.

Once the new substation is in service, there will be work over several months to transfer supply over from the old substation. Following that process, the old substation will be decommissioned and the equipment removed, and the final fencing and landscaping will be completed.

Chin shroud arc visor proves best protection E SSENTIALEnergy has worked with safety equipment manufacturer, Elliotts Australia, to design and adopt a new arc-rated visor with shroud to reduce the likelihood of facial burns and breathing difficulties associated with electrical flash overs.

The arc-rated visor was among a range of personal protective equipment tested at Ausgrid’s Lane Cove testing facility recently.

During the testing, Essential Energy’s HSE Design and Improvement Coordinator, Daniel Germany, observed how visors without a chin cup allowed flames and hot gasses to enter – resulting in significant facial and neck injuries to the wearer.

“The addition of a chin cup greatly reduced the amount of heat and energy in contact with the face,” Daniel said. “A visor was then tested that had an arc-rated cloth shroud and it gave excellent results.”

This visor was part of a helmet that did not meet the Australian standard Occupational protective helmets AS/NZS 1801:1998, so Essential Energy approached a number of suppliers to design a visor that could be fitted to its existing helmets.

“We received a number of prototypes that were tested at the Ausgrid facility with the Elvex visor from Elliotts – fitted with a 40 calorie-rated TecaSafe shroud – delivering excellent results,” Daniel said.

The Energy Networks Association’s recentlypublished NENS 09-2014 National Guideline for the Selection, Use and Maintenance of Personal Protective Equipment for Electrical Arc Hazards which recommends the addition of a chin cup or arc-rated fabric shroud when selecting an arc-rated visor.

The design prevents hot gases and flames from entering the facial area of the user and reduces the likelihood of burns and breathing difficulties.

“This visor and shroud provide the best rated protection for our employees in the event of an electrical flash over and is currently being implemented across our network,” Daniel said.

Elliotts Australia National Business Development Manager Brad Hawkins said they were delighted to have collaborated with the Essential Energy team on this new PPE initiative.

“Designing PPE is a specialty area for Elliotts and we are known for our passion for delivering safety gear that meets all quality standards,” Brad said.

“It was very rewarding to assist in creating Essential Energy’s new arc-rated cloth shroud and exciting to hear that it’s being adopted across Essential Energy to improve the safety of all their employees.”

Tight squeeze for Bathurst zone substation upgrade

T

HE task of replacing ageing equipment in a zone substation with site constraints while maintaining supply to more than 7,500 local residents and businesses meant for a challenging project for Essential Energy in Bathurst’s CBD recently.

The Russell Street overhaul included removing the existing outdoor 66kV bus bar and three 10MVA transformers that had reached the end of their service life and replacing them with 66kV Gas Insulated Switchgear (GIS) and three new larger transformers.

Subtransmission Planning Engineer, Brendan Brewer said there were considerable challenges

associated with the project including the limited space to work within, the current peak demand of the area and the site being operational.

“We kept planned supply interruptions to a minimum with one transformer maintained at the site at all times and the remaining load distributed between two of our other zone substations,” Brendan said.

Subtransmission Development Manager, Jason Streatfeild, said the biggest challenge involved in refurbishing the small zone substation site was its severe access restrictions.

“Following two major flood events in Bathurst in the 1990s, a levee bank was constructed around the town centre and the

Above: In total seven bays of GIS in position ready for site works to commence Page 6 - Australian Power & Energy News

zone substation is located in line with the levee with a concrete wall surrounding the site on two sides,” Jason said.

“Due to the space and site restrictions, we used GIS technology to replace the existing outdoor air insulated busbar and equipment rather than try and duplicate the existing infrastructure.”

The space saving was substantial – the GIS equipment occupies an area of just seven metres by four metres compared to the old

equipment previously requiring about six times that space.

The extra space was used to help with staging the works, replacing the transformers with much larger units and dismantling the old equipment.

The compact replacement will also enable the future construction of a new control building and an 11kV indoor switchboard to help ensure Bathurst CBD’s power needs are catered for into the future.

Is your clothing NENS09 compliant?

E

NERGY Networks Australia (ENA) sets the standards through their National Guidelines more commonly known as NENS09 for the selection, use and maintenance of PPE for electrical Arc Hazards.

Managing Director of leading safety wear manufacturer Elliotts, Anthony Elliott knows NENS09 guidelines so well having manufactured and accredited many PPE products to both Australian and overseas standards. Anthony says, â&#x20AC;&#x153;Put simply these guidelines separate PPE into 5 categories, Base Garments, Undergarments, Arc rate Outer Garments, and Rainwearâ&#x20AC;&#x2122;. Previously these standards only recognised two main categories; primary protective clothing and secondary protective clothing but now all five categories are included to ensure the safety of workers in the power and energy sector. It is so important to ensure that when you buy PPE and clothing that it does meet these standards so you are not putting yourself at riskâ&#x20AC;?.

To help readers here is a quick checklist of what to look for in each category.

Base Garments: the clothing you wear day-to-day like your trousers, long sleeve shirts, and overalls.

a Make sure these garments are manufactured

from arc rated materials. Check the clothing labels for this specific feature.

a Heavy woollen knitwear or felted spun wool

blanketing fabric is a great option!

X Must not contain any flammable melting materials

Arc Rated outer Garments are worn when higher levels of arc protection is required, and are worn over base garments. These garments include switching coats, leggings, coveralls and jackets.

Undergarments: singlets or any garments that are worn under your base garments.

X Flammable, melting synthetic undergarments should never be worn.

a Wool is a great option for undergarments as it presents no ignition risk!

Thermal Outer garments: Thermal outer garments are worn over the base garments to keep you warm when working in the colder temperatures.

Itâ&#x20AC;&#x2122;s important to note that any garment which is not arc rated should not be relied upon to provide additional or increased arc protection.

Keeping water out of your Test Instruments I

T IS REALITY that much electrical work takes place outdoors where there is always the possibility a shower of rain will come at the most inconvenient time, inevitably in the middle of testing or when there is no time to find cover. Then there is always the risk of your instrument taking an unplanned dip into water.

The majority of test instruments have no moisture protection and therefore cannot be used safely in even the lightest of shower of rain. If you accidentally drop it into water, a visit to the service centre will take priority over completing the job.

Pacific Test Equipment has the solution with a weatherproof answer to almost every type of field test instrument and the good news is they don’t come at a premium price!

In fact in many instances they will cost you less than what you may be paying for nonweatherproof models!

IP Ratings The IP rating of a product indicates the degree of protection meaning under what conditions it will keep moisture out.

The starting point is IP54 which is protected from water falling from above when used in the normal operating position. Generally an instrument with this rating can be used in rain where it would normally be safe to continue work.

The next level is IP55 or IP56 where it is protected from water entering from any direction commonly referred to as hoseproof.

The highest level is IP67 which is submersible up to a depth of 1 metre and while you are unlikely to be testing under water, if you accidentally drop your instrument into water it will float to the surface and survive.

Of course IP67 instruments can be used in any position even in monsoonal rain if you really have the urge to test under these conditions!

IP Rating with Safety There would be little point keeping the water out if the instruments did not also meet the highest safety rating. IP rated instruments offered by Pacific Test Equipment also meet a minimum of Cat 4, 600V safety making them suitable for use on unprotected mains.

True RMS Multimeters The starting point is our French designed IP54 Chauvin Arnoux CA5233 which is low priced but has many unique functions such a Low Impedance range (to eliminate ghost voltages) non-contact voltage detection where the screen turns bright red when off and is in proximity of live conductors, temperature & capacitance measurement plus all the normal ranges you expect on a general purpose multimeter.

The next level is the IP67 Sonel CMM-40 40,000 count multimeter with a class leading accuracy of 0.06% and includes temperature, capacitance, peak capture, duty cycle and a memory.

Weatherproof + Intrinsically Safe The Metrix MX57Ex (also from Chauvin Arnoux in France) is both weatherproof to IP67 and intrinsically safe to IECEx standards.

Apart from being able to withstand total immersion, the MX57Ex can be used safely in dangerous and explosive atmospheres such as gas and petroleum sites and many mine sites.

Clampmeters Due to their moving jaw necessity, keeping moisture out of clampmeters has been challenging until now when AEMC solved the problem with a range of unique IP54 True RMS Clapmmeters all with in-rush current capture and the highest Cat 4, 1,000V safety rating.

There are 8 models in the range with the choice of either 48 or 60mm jaw sizes. Versions cover AC only or AC/DC, Temperature, Power measurement, Power factor, Harmonics, Memory, Bluetooth with DataView software and an Android app for capturing tests on your smartphone.

Insulation Testers Costing around the same or less than other quality insulation testers with no moisture protection is the IP67 Sonel MIC-10. Test voltages from 50 to 1000V are provided plus resistance, continuity and capacitance measurement.

If higher test voltages are required Sonel also offer IP54 Insulation Testers with test voltages of 5,000 or 10,000 Volts.

All Sonel Insulation Testers are Cat 4, 600V safety rated.

Other Weatherproof Field Testers Sonel’s range of IP 67 testers include Loop Testers, RCD testers and a unique combination RCD and loop tester.

Supply Loop Impedance Testing A

USTRALIAN STANDARD AS4741 details a requirement for the Supply Loop Impedance to me measured between Phase and Neutral and places a limit of 1 Ohm at the point of attachment between the supply and a consumer.

Supply Loop impedance differs from the more common Fault Loop Impedance measured between Phase and Earth and is applicable to the wiring within an installation.

How is Supply Loop Impedance Measured?

Loop impedance is measured by drawing a current from the supply and measuring the voltage drop caused by the current. To achieve accuracy on a supply system where the loop impedance should be very low, the current needs to be higher than what is required for installation work.

A standard loop impedance meter can

Page 8 - Australian Power & Energy News

be used for both Ph-N and Ph-E tests but there are significant and sometimes overlooked limitations when using many meters designed primarily for installation applications on supply loop impedance testing.

Because the measurement is on the unprotected mains a Cat 4 instrument is mandatory, compared to a Cat 3 rating for installation testing.

More importantly because the pass/fail criteria is 1 Ohm it is important that this be measured with a reasonable degree of accuracy.

The final consideration is that the instrument be suitable for field conditions, including wet weather and working aloft. It has to be simple while using gloves and goggles under all conditions including poor light.

New Ararat Terminal Station to Connect Ararat Wind Farm to National Electricity Grid V

ICTORIAN electricity business Transmission General Holdings Australia (TGHA) announced an agreement recently to connect the Ararat Wind Farm’s 75 turbines that will deliver 242MW of renewable energy capacity into the national electricity grid. As part of the arrangement, TGHA will design and construct, own and operate the new terminal station and 21 km of 132kV powerlines.

TGHA’s Tim Rourke said the Ararat Terminal Station project marked a significant step forward in supporting the Australian renewable energy market, taking advantage of the more favourable investment environment for such projects.

Mr Rourke added, “Transmission General Holdings Australia is excited to be partnering with Ararat Wind Farm to bring this project online. As more and more large-scale renewable generation projects are developed in the coming years, our business is well positioned to ensure they are connected to the grid in the most efficient manner possible.”

Construction of the network is expected to begin in July 2015, and completion is scheduled for August 2016.

The project is expected to employ more than 200 Victorians and is a further testament to Western Victoria as an attractive location for wind generation, given its excellent wind resources and topography, strong transmission infrastructure backbone, and beneficial physical location in the National Energy Market.

Sister company Powercor Network Services (PNS) will undertake the design and construction of the new terminal station and transmission line for Transmission General Holdings Australia (TGHA), jointly owned CKI and Power Assets Holdings Ltd. This will be the second transmission asset to be owned and operated by TGHA, the other being the Mt Mercer Windfarm project and Elaine Terminal Station, southeast of Ballarat.

The $250 million Hornsdale wind farm, to be developed by French company Neoen, will be located in the Mid North of South Australia, around the town of Jamestown.

Hornsdale is touted as Australia’s “best’’ wind farm project due to its high capacity factor of almost 50 per cent when compared to other wind farms in Australia which operate between the high 30s or low 40s.

When completed the wind farm will produce a maximum of 315 megawatts of power.

SA’s Climate Change Minister Ian Hunter welcomed the $250 million investment and said the project was one of many in the pipeline arising from the a focus on increasing renewable energy.

“Around the world there is fierce competition for the billions of dollars of investment available for renewable projects,” he said. “Projects such

as the Hornsdale Wind Farm help us generate energy from clean, renewable sources.”

He said the government is committed to ensuring South Australia fully capitalises on the opportunities of transitioning to a lowcarbon economy.

“Climate change leadership, clear targets for renewable energy and associated regulatory support have made us competitive in the global race to attract investment for renewable projects,” he said.

“This project helps reinforce South Australia’s reputation as the country’s foremost renewable energy state, and helps contribute to the $10 billion low carbon investment target as well as the 50 per cent renewable energy target, both to be achieved by 2025,” he said.

“South Australia has established itself as the nation’s leader in wind energy investment, having attracted 41 per cent of the nation’s installed capacity.

“Our State has an international reputation if it were a nation state, South Australia would be second only to Denmark in regard to wind energy.”

Building work begins on Victorian wind farm to supply ACT with renewable energy

B

UILDING work has begun on a $50 million wind farm in Victoria which will supply renewable energy almost 700 kilometres away, in the ACT. The Coonooer Bridge Wind Farm, northwest of Bendigo, won a 20-year feed-in tariff in the ACT Government’s wind auction.

Environment Minister Simon Corbell said the six turbines at the wind farm would generate the lowest cost wind energy in Australia.

“The price being paid through the feedin tariff law for the Coonooer Bridge wind farm is $81.50 per megawatt hour, that’s the cheapest price ever achieved for wind energy in Australia,“ he said.

“It means that Canberra electricity consumers are getting large-scale renewables at a very affordable price.

“And we have been able to achieve that because of our innovative reverse auction feedin tariff law and the fact that we have selected some of the most productive wind sites in the country.”

The project is jointly owned by Canberrabased company Windlab Systems and neighbouring landholders.

Mr Corbell said the project would generate enough electricity to power thousands of Canberra homes.

“With the start of the Coonooer Bridge wind farm we’re well on the way towards 90 per cent renewables,” he said.

“About 12,000 Canberrans will be powered by this one single project.”

Another two ACT-backed wind farms are in development.

HE proposed Mt Emerald Wind Farm received Development Approval from the State Government recently.

Deputy Premier and Minister for Infrastructure, Local Government and Planning Jackie Trad MP gave the green light to the A$380 million wind farm near Cairns after the

State Government took over responsibility to assess the development from the Mareeba Shire Council in June 2014.

Ratch’s business development general manager Anil Nangia said State approval was a significant achievement and a major milestone for the Project, which promises to be a model of sustainable development.

TMAC ACTIVE INNOVATION - for PV Systems with Fluctuating Voltages

ACTIVE INNOVATION CASE STUDY

Automatic tests deliver definitive results in less than

one

MINUTE

A new industry problem solved by TMAC’s portable testing device.

In areas where multiple PV systems are connected to the local grid, competing currents raise the voltage levels above the acceptable range, causing fluctuations and repeated system shutdowns. Utility companies have been fielding many customer complaints on a daily basis.

Fixing this problem wasn’t easy. There was no existing device that could identify which individual household connection was causing the issue. Technicians relied on manual monitoring of the PV systems with data loggers – a time-consuming approach that still didn’t pinpoint exactly which connections were at fault.

Active innovation One Queensland utility company approached TMAC to see if we could find a better way.

We developed a testing device that could be placed between the grid supply and the Grid-Tie Inverter. It was robust enough to handle the 5KW throughput into the grid, and contained an LCD display to digitally record the voltage.

Page 10 - Australian Power & Energy News

A better way After further collaboration between TMAC and the utility company, we fine-tuned the device and incorporated additional features.

Called the TMAC Grid Tie Voltage Injection Set (GTVIS), this fully Australian Standards Approved device is easy-to-use, inserting directly into the service to automatically test for problem connections.

GTVIS is now being extensively used by the utility company throughout their network and there is considerable interest from other utility companies across Australia.

This device is saving countless technicians hours, making local area networks more reliable, and dramatically reducing customer complaints.

TMAC rose to this new industry challenge. We knew this was another opportunity to apply our expertise to create an innovative solution.

Utilities Web Portal Solution Launched by HAWCS

P

OWER Utilities invest heavily in ensuring that electricity reaches the end user without disruption and it’s a never ending quest. As we approach a new bushfire season it’s a reminder that this sun drenched continent of ours is the natural habitat of bush fires.

As communities spread beyond the cities and further into the bush, extra pressure is placed on those who manage our power lines.

However, to anticipate a single component failure in any particular distribution network is an extremely difficult task; to predict a failure before it happens and one that could lead to, not only a blackout but worse. As maintenance budgets are squeezed, better and more targeted solutions are required.

HAWCS, with more than 17 years experience in the utility industry, is launching an Australian first that delivers real time data analysis from multiple sources to gauge risk and target maintenance spend where it’s needed.

The HAWCS Solution: A realtime web portal service for electricity providers HAWCS now provides a log-in web portal service which can be accessed by power utilities. The technology applied uses advanced algorithms and it allows a power utility to in effect, obtain a bird’s eye view of power lines and associate componentry. It will identify weaknesses in a particular network so that the utility is much better placed to apply its maintenance budget in a far more cost effective manner.

HAWCS, with a fleet of 9 helicopters, is ideally placed to deliver such a service as its capacity for aerial inspections and data collection is well proven. The company has been conducting aerial power line and rail inspections since 1998 and has already exceeded one million kilometres in patrols.

The company’s Managing Director and highly experienced pilot, Galen Gunn believes that the service his company can now provide represents the future and a more efficient way of maintaining power lines, as he says; “This is an exciting development for the utilities industry. Although we’ve always been able to provide data in spread sheet form which in itself is extremely helpful, the new web portal service takes HAWCS’ data analysis to a much higher level including risk profiles and maintenance sheduling.

“We’ve made it far more user friendly and when accessed, a company can instantly see the status of its network and take a closer look at any particular section of a power line and its components.

“Because it’s a real time view, decisions can be made in a far more cost effective manner so that the power utility’s maintenance budget can be accurately targeted and provide greater value for the money spent.”

HAWCS’ track record is unique and second to none HAWCS uses detailed asset inspection techniques to achieve accuracy in both defect identification and location. High resolution imagery is taken of all assets and then inspected post flight by experienced linesmen.

At this resolution, 99% of defects are accurately detected and the position of the defect is referenced to the Utility’s Pole ID. All defects are coded according to the Utility’s guidelines and then reported not only through excel spreadsheets for seamless integration into the utility’s existing GIS systems, but will be fed directly to the utility’s web portal for immediate and direct access by their own inspectors. PDF reports are also generated to give asset managers an overall perspective of the condition of each feeder and maintenance area.

To date, any urgent defects detected by experienced HAWCS’ observers have been reported immediately to the utility. However, with the new web portal service urgent information will be available in real time and can be accessed on the utility’s tablet .

In inspection mode HAWCS operates its fleet of helicopters from above 300 to 1000 feet by utilising intelligent technology. The greater the flight height, the safer the operation.

Flying higher also results in less disruption to customers allowing more of the network to be inspected efficiently from the air.

HAWCS was the first to conduct urban patrols over cities and townships from 1000 feet. The company owns and operates its fleet of helicopters which have the lowest noise signature of their class in the world. This aspect minimises the environmental impact on customers and livestock.

LiDAR - HAWCSCAN Light Detection and Ranging (LiDAR) has transformed the way utilities see their network.

HAWCS is the most experienced provider of LiDAR data to the Australian electricity industry. From conducting the first power line construction LiDAR survey in the country to delivering more than 43,000 line kilometres of data capture, processing and reporting in 2014 alone. HAWCS is at the forefront of this industry-wide technological breakthrough.

The utility benefits using LiDAR technology There are a range of benefits: • Accurate vegetation analysis customized to the Utility’s guidelines • Pre-modelling to determine ground, road and water conductor clearances • Accurate positioning of all assets in the network GIS

Page 12 - Australian Power & Energy News

• LiDAR and detailed patrols on all voltages from transmission, sub-transmission, HV, LV service wires and private mains.

• Thermal ratings with PLS CADD determining maximum sag on conductors.

HAWCS operates a 500 kHz scanner from its helicopter platform which delivers superior point density of 40 to 80 points per square metre flying at optimum patrol speed. The accuracy of each and every point is two centimetres relative to 5 centimetres absolute.

With their wealth of experience, HAWCS’ systems have continued to evolve meeting the ever changing demands placed on utilities.

Moving through the complexities of data acquisition across all voltages; each requiring different methodologies, to data delivery and storage.

HAWCS have also improved their advanced algorithms to enhance vegetation encroachment reporting, accurately identifying a wider degree of vegetation issues such as tree fall-ins, regrowth, ground diameters and stem counts.

This automated process also reduces data processing turn-around times.

The new web portal service provides a much clearer window of opportunity for electricity providers to enable them to better allocate maintenance funds. Keeping electricity flowing to industry and consumers relies on the integrity of power lines and throughout communities across Australia, our standard of living can often depend on a flick of a switch.

Power Improvement projects on the go around Longreach S EVERAL large power improvement projects worth more than $ 2 million are nearing completion in the Longreach area.

Customer Delivery Manager Pioneer Chester Brodie said the work aims to improve network performance and service delivery to 396 customers supplied by part of the 22kV Morella feeder that runs north/north west of Longreach along the Landsborough Highway towards Winton.

The power line on this section of the Morella feeder network has been repaired multiple times due to bird strikes, lightning strikes and general ageing and is being rebuilt to new standard with new line and extra phase clearance to reduce the impact of natural elements.

The 22Km section of the backbone on the Morella feeder that is being upgraded at the moment, supplies four separate SWER lines to the northwest including Leander, Bude, Hereward and Darr.

Local crews from Ergon’s Longreach Depot are performing the work on the Morella upgrade and are gaining valuable on the job experience in the construction of a large project and the opportunity to gain additional licencing for individual members which will benefit the group into the future.

The project has also provided much needed stimulus into the local economy with local contractors from Barcaldine and Longreach being engaged to undertake line clearing and transporting of poles and equipment.

In addition high voltage exit cables from Longreach Zone Substation have been upgraded to both Swan and Wompoo feeders securing capacity and allowing greater opportunity for load shifting to improve operational flexibility.

Several switches with remote capabilities have also been installed under a separate project aimed at being able to isolate faults quicker and reduce customer outage times.

A

usNet Services is on track to complete its $40 million Dandenong Ranges powerline upgrade project by April 2016, having relocated more than 30 kilometres of existing powerlines underground.

SSENTIAL Energy crews restored power to more than 6,000 customers across south eastern New South Wales after heavy snowfalls in July caused extensive damage to the electricity distribution network and widespread supply interruptions.

Customers in Mount Canobolas and Nashdale, south-west of Orange; Blayney, Oberon and Trunkey Creek in the Central Tablelands; and Crookwell, Goulburn, Taralga and Binda in the Southern Tablelands were affected by power outages.

Regional Manager South Eastern, Phillip Green, said the severe weather created a number of challenges for Essential Energy’s teams on the ground.

“Patrolling the powerline to identify the fault and determine the extent of the damage was particularly difficult as crews were faced with road closures, deep snow and unstable ground,

Dandenong Ranges powerline upgrade reducing outages and increasing safety

limiting access to some locations,” Phillip said.

In spite of the conditions, power supply restoration progressed at a steady rate with local crews adopting a range of strategies to locate faults and repair the electricity network, including the use of all-terrain vehicles to improve accessibility.

“In many areas, crews patrolled powerlines on foot and carried in equipment necessary for making repairs,” Phillip said.

“Helicopters were used to patrol powerlines across the Central and Southern Tablelands in areas that were inaccessible to ground crews to expedite assessment of the extent of the damage to the network.

“The majority of network faults were caused by powerlines and cross-arms being brought down under the weight of snow and ice buildup, and vegetation contacting the network.

“Additional crews and all-terrain vehicles were sourced from across the southern part of

the State to assist local teams during the major restoration operation.”

Essential Energy liaised with affected customers throughout the duration of the outages, prioritising the allocation of resources and restoring power as quickly as safety would allow, minimising the impact on local communities.

The two-year project involves relocating approximately 50 kilometres of overhead highvoltage (22,000-volt) aerial bundled cable (ABC) underground and replacing a further seven kilometres of the cable with a modern design.

AusNet Services’ project manager, Aaron Emmerich, is pleased with the progress and thankful to the local community. “AusNet Services would like to thank the local residents and broader ‘Hills’ community for their patience and understanding while we undertake this project to improve supply reliability and reduce bushfire risk,” Aaron said.

“Since April 2014, we’ve relocated more than 30 kilometres of overhead powerlines underground and replaced more than five kilometres of ABC powerlines within the Dandenong Ranges.

“This progress has been made possible through collaboration with local stakeholders, including the council, and a new innovative ‘hybrid’ underground cable system we specifically developed for the unique challenges of this project,” he said.

Under the company’s ‘hybrid’ system, cables are buried along roadways, only rising out of the ground to connect to existing powerpoles to deliver electricity into homes via existing overhead low-voltage powerlines. This removes the common use of large cabinets connected to the underground cables, which weren’t an option due to the lack of available, flat ground space.

“This approach utilises the footprint of the existing powerpoles, therefore, reducing the impact to the environment that other methods may otherwise place at risk,” Aaron said.

“Importantly, the upgrades are already improving the reliability of supply for residents and businesses by reducing the interference from vegetation and animals,” he said.

While this project is expected to finish in April 2016, AusNet Services has completed and will be undertaking new projects in the broader Dandenong Ranges that involve installing insulated cable and undergrounding powerlines.

Morse Power the Safer, Smarter Choice

V

ICTORIAN manufacturer Morse Power continues to build on its reputation for excellence in the power and energy sector, not least due to its range of equipment specifically designed and developed for the maintenance of transmission and distribution networks.

There is nothing standard about how Morse Power goes about its business.

In house there’s a fully equipped CNC workshop and a hands-on team of qualified engineers and highly trained machinists who continue to design and develop products that make the job for those who maintain our electricity networks easier.

It’s a range of equipment that is designed to withstand the rigours of life in the frontline and with an emphasis on safety for the user.

Importantly and prior to developing any product, Morse Power conduct extensive research and consult with leading companies within the energy sector so that any equipment created is targeted appropriately and purpose built. Along the way the company will produce multiple prototypes before the design of the end product is achieved.

At Morse Power the starting point may be Australian and international standards but the end product sits well above and beyond those benchmark requirements.

The result is a range of cable handling equipment which includes linesman tools, pole stands, cable drums, stands and winders; self-loading trailers and spreader bars and each item has an inherent quality of workmanship that is second to none.

It is that kind bespoke craftsmanship that is reflected throughout the Morse Power range.

For instance the company’s range of cable drum stands are all load rated and designed for multi-purpose cable drum storage and safe handling. The cable drum stand can be used for static storage, onsite lifting and the transportation of cable drums. It can also be used for the unwinding of ropes, cables and conductors either freely or under tension.

The drum stand with the addition of a Morse skid mounted power pack can be used for cable recovery and it’s designed to accommodate both crane and forklift relocation with multiple tie-down points for safe transportation.

On site operation of the cable drum stand is smooth with a removable spindle which is fully supported on roller bearings connected to a ‘payout’ brake to facilitate

Above: 6 Tonne Cable Drum Stand

tension control on the cable. The company provides the cable drum peg and 3 sets of spindle collars to suit different size drums and can custom manufacture additional collars if required.

Flexibility is a key advantage with Connector Kits available to link multiple 3 tonne cable drum stands for more efficiency. The skid mounted power rotator uses a petrol or diesel powered hydraulic power pack and drive.

There’s a spreader bar to ensure safe lifting of the cable drum and even a remote control brake system that can be operated at a safe distance.

Morse Power manufactures a 1.5 tonne, 3 tonne and 6 tonne cable drum stand but what sets the company apart is that it is solution orientated. The team, under the guidance of Tim Morse, whose design and engineering talent is in demand globally by companies in both the traditional and renewable energy sectors, enjoys the challenge of directly responding to a client’s needs with purpose built equipment.

Above: 500kg Power Pack

For instance, as in the case of any product and whether it exists or not, the team can produce a cable drum stand to suit the required performance range beyond the scope of normal production line output.

Morse Power spreader bars are custom designed for safe installation or removal of the cable drum spindle assembly to the drum stands. The standard range is available in 1.5 tonne, 6 tonne and 12 tonne models and they are load tested and rated. Fork lift or crane access models are also available with lifting access points incorporated.

Above: Spreader Bar

500kg Power Packs are available in diesel or petrol to be used in conjunction with the range of cable drum stands to assist with winding operations. Made with heavy duty steel and powder coated for corrosion resistance, the power packs feature an electric start button and have tie-down points for forklift carriage. Each pack stands on rubber feet to minimise vibration and the pack has an emergency stop button.

Morse Power is certainly a company on the move and with a list of customers such as Energex, Ergon Energy, Jemena, Powercor, SA Power Networks, AusNet Services, TasNetworks, Thiess, Transfield, Vemco Group, West Coast Energy, Western Power, ZNX, and Zinfra Group – it can only continue to grow in influence with its high quality range of winning products.

World-leading technology to power Flinders Island Flinders Island “Hybrid Energy Hub”

T

ASMANIAN innovation will see the majority of Flinders Island’s energy needs supplied by renewable energy within two years.

Hydro Tasmania has started work on developing a “Hybrid Energy Hub” on Flinders Island that will significantly increase renewable energy use on the island and reduce the use and importation of diesel.

“Like many remote or island locations, Flinders Island is currently heavily reliant on expensive diesel fuel to supply its electricity needs,” said Project Director Simon Gamble.

“Diesel fuel remains the single largest expense in these remote systems and using renewable energy makes good economic sense.”

Development of the Hybrid Energy Hub follows the success of the King Island Renewable Energy Integration Project (KIREIP), which has seen King Island’s energy needs supplied solely from renewables when conditions allow, a world-leading breakthrough.

KIREIP uses a range of renewable and conventional technologies to reduce diesel consumption for power generation on the island. The hybrid power system is comprised of wind, solar, battery storage, flywheels, dynamic resistor technology, dynamic load control and the use of biofuels.

“This combination of technologies means KIRIEP can securely and reliably generate power for King Island, even during lulls in the wind or when the sun isn’t shining. When conditions are right, KIREIP delivers 100 per cent of King Island’s power from renewable sources, reducing the cost of providing electricity to the island,” Mr Gamble said.

The $12.88 million Flinders Island project is the next step in off-grid hybrid system development. The hybrid system will be capable

of displacing up to 60% of the annual diesel fuel used on the island to generate electricity.

It involves integration of wind and solar generation with the existing diesel power station, and installation of enabling technology, such as flywheel and battery energy storage, in a new form designed to drive down the cost of these systems.

Hydro Tasmania has worked with Tasmanian manufacturers to develop a series of modular units to house and ship the enabling technologies essential to the energy solution. This innovation will be developed and tested for the first time through the Flinders Island Hybrid Energy Hub project.

These modular enabling units will provide a lower-cost and scalable solution that will allow easy and rapid transport and installation for renewable energy projects, and which could also serve temporary uses such as in disaster relief or in the mining industry.

Fabrication and testing of equipment takes place off-site, ensuring a speedy roll-out at the final location, reducing the risk, cost and duration of construction.

“The combination of our hybrid energy solution and the state’s skilled fabrication industry positions Tasmania well to supply these hybrid systems to a growing market throughout our region,” Mr Gamble said.

One such opportunity is Energy Developments Limited’s Coober Pedy project, incorporating wind, solar and enablers, which aims to achieve a 70 per cent reduction in diesel fuel used for power supply to the township of Coober Pedy.

Hydro Tasmania has been assisting EDL with the development phase of this project which would make use of the Tasmanian designed and manufactured modular enabling units if it proceeds to implementation.

Contracts signed and work to start on Flinders Island Hybrid Energy Hub

H

YDRO Tasmania has signed contracts totalling nearly $4 million to allow work to begin on a major renewable energy project on Flinders Island.

The Flinders Island Hybrid Energy Hub will significantly increase renewable energy use on the island and reduce the use and importation of diesel.

“We are very pleased to be working with Tasmanian manufacturing excellence to achieve this. In putting together the fabrication team we didn’t need to look

outside the state and it’s great that our business is able to partner with other leading Tasmanian businesses to realise this solution, namely Southern Prospect, Doric Engineering and Bartech”, said Project Director Simon Gamble.

“We had a terrific experience working with Lee Whiteley and his team during the King Island project and it’s great to have Southern Prospect enthusiastically on board.

“I fully expect that this won’t be the last time we are in a position to announce work involving our highly skilled Tasmanian

Above: Site map showing existing power station and new layout Page 16 - Australian Power & Energy News

manufacturers. We are working hard to bring to fruition similar island power projects across Australia and the Asia Pacific region and we look forward to bringing home the benefits of those projects to Tasmania,” Mr Gamble said.

The Australian Renewable Energy Agency (ARENA) is supporting the project with $5.5 million funding. ARENA CEO Ivor Frischknecht said the project would provide the Flinders Island community with improved energy security and would enhance skills and job opportunities in the Tasmanian region.

“Australia is a large country with many off-grid communities and industries facing energy supply challenges similar to Flinders Island. ARENA is committed to working with Hydro Tasmania to share the learning and expertise gained,” Mr Frischknecht said.

Contracts awarded in August cover many of the key components of the project.

With Southern Prospect you can seize the day

By Kevin Glancy

A

S the name suggests, Southern Prospect is about partnerships and prospects; about taking an idea from concept to reality and for this enterprising company every problem brought to its attention is simply an opportunity to excel.

This dynamic Tasmanian power house with an eye on the bigger picture and a highly skilled team who can walk the walk, loves a challenge.

Under the leadership of Managing Director Lee Whiteley, it’s a company with the resources and skill to respond to any challenge within the power and energy sector, whether in traditional power generation, liquid natural gas production or in the world of renewable energy.

However, there’s yet another valuable edge to Southern Prospect which should be an attractive proposition for any potential client, as Lee Whiteley explains.

“When we embark on a project value adding is first and foremost on our minds. We always consider the longer term interests of our clients.

It’s not simply about providing a solution, it’s about how we can respond so that our client’s business interests can be further enhanced by that solution, both in terms of greater efficiency and profit growth.

“We see our relationship with every client as a partnership. It’s a team effort and we prefer to work on end-to-end solutions because in that

Above: Mr Lee Whiteley, Managing Director, Southern Prospect

mode we are best placed to achieve the most effective outcome.”

Located in Wynyard, Tasmania there is no geographical limit to Southern Prospect’s operational reach. The company’s problem solving skills are available throughout Australia and beyond.

From its dedicated facility the company can provide concept designs with engineered detailed drawings and once the design is agreed upon Southern Prospect can take care of the rest.

From certification, fabrication, blast and paint, manufacture, testing and installation. Once the project is completed Southern Prospect can provide operational service literature as well as maintenance and troubleshooting if required.

There are two recent projects that highlight the company’s broad capacity and its ability to respond to the needs of diverse industrial sectors.

The first involves renewable energy. Southern Prospect were awarded a contract to supply a packaged Diesel Uninterruptable Power Supply (DUPS) for Hydro Tasmania’s Flinders Island Hybrid Energy Hub project.

The company is manufacturing custom enclosures and packaging the DUPS system and providing the cooling system, exhaust and acoustic controls. The enclosures are designed to be modular so that once on Flinders Island they can be easily assembled as part of Hydro Tasmania’s 100% renewable energy facility.

Southern Prospect will also ensure that the design and packaging of all components will withstand the rigours of transport by ship to Flinders Island. It’s just the kind of project that the company enjoys as Lee Whiteley confirms.

“This project is a great match for Southern Prospect. It combines our strengths in project management, design and advanced manufacturing and is a great opportunity to showcase our capacity and capability.”

The second project was much more down to earth and in fact involved the refurbishment of a giant storm water grit collector located 8.5 metres below the ground in St John Street in Launceston.

The ‘Gritter’ as it is affectionately known, was installed below the banks of the North Esk River over 40 years ago. It weighs 3 tonnes and is as tall as a three storey building. Its purpose is to remove rocks, gravel and other debris collected in the storm water run-off as it makes its way through the streets and drains of Launceston.

Once the Gritter was removed from its location it was totally overhauled by the team at Southern Prospect in its Wynyard facility. The refurbishment was a success and improved the capacity of the grit collector to remove sediment

from the combined sewer and storm water network and in turn, reduced the frequency and impact of discharges to the waterway.

Southern Prospect’s upgrade on behalf of TasWater brought the old Gritter up to the environmental standards expected in today’s modern sewerage systems.

These two contrasting projects along with many others completed by the company clearly

illustrates the wealth of in-house talent and its diversity. The ability to solve problems in a variety of sectors is an invaluable asset and there’s no doubt that Southern Prospect is a company to watch as it continues to seize the day on behalf of its increasing range of visionary clients.

Introducing SA Power Networks’ first female Apprentice of the Year, Jessica Wooley F OR the first time in its history, SA Power Networks has awarded its Apprentice of the Year Award, the Playford Medal, to a female apprentice — Jessica Wooley.

The coveted award, which is presented to SA Power Networks top graduating apprentice each year, recognises leadership, hard work, commitment and technical ability.

Originally from Kangaroo Island, Jess moved to Adelaide in 2011 at the age of 17, away from her family and friends, to begin her apprenticeship in what was (and still is) a heavily male dominated industry.

Jess applied for the apprenticeship after completing Year 12 on Kangaroo Island. As part of the rigorous testing to gain the position, Jess sat a written exam and also climbed a Stobie pole — not something most 17 year old girls would be expecting to do!

After graduating in February this year, she is now a qualified electrician working as part of the SA Power Networks substation maintenance team that services and maintains South Australia’s electricity substations.

“I’ve always been an adventurous and sporty person and knew my career would involve being outdoors,” said Jess. “I grew up on a hobby farm, owned a motorbike and enjoyed fixing things in the shed with my Dad.” “Moving from the Island to Adelaide, living by myself and starting a new job was difficult, but looking back on it, it’s the best decision I made, even though it hasn’t been without its challenges,” said Jess.

“The person I am now is because of those decisions I made early on and I’m incredibly proud I’ve achieved so much in a short time.”

Among many triumphs, Jess has identified opportunities and used her initiative to find a better, more efficient way of doing things.

During her apprenticeship, Jess initiated and designed an electronic calculation sheet for transformer ratio tests. This has now been incorporated into SA Power Networks Quality Management System and is an integral part of what was a complex process.

“Jess has displayed a strong work ethic that can’t be faulted both on the job and around the depot,” said General Manager, People & Culture, David Syme.

“We’ve been committed to employing more female staff across the business and Jess has proved she can contribute in many ways including undertaking tasks in what has traditionally been seen as ‘men’s work’.

“Being named our top apprentice is great recognition and truly deserved as she has been an outstanding apprentice,” Mr Syme said.

“Jess has also recently been named a finalist in the Apprentice of the Year category of the 2015 South Australian Training Awards. The winner will be announced at a gala dinner in September.”

SA Power Networks has seen an increasing number of females apply and succeed as part of its Apprenticeship Program.

“SA Power Networks currently employs 24 female trade apprentices. This has increased significantly in the last two years as we’re

Hydro Tasmania employee wins international Award for Excellence H YDRO Tasmania’s ongoing contribution to the sustainability of hydropower development and operation internationally has again been recognised with an award presented last month in China.

Dr Helen Locher, Hydro Tasmania’s principal consultant for sustainability, was presented with the 2015 Mosonyi Award for Excellence in Hydropower during the 2015 World Hydropower Congress in Beijing. Dr Locher joined Luiz Gabriel Azevedo and Jean-Étienne Klimpt as the winners of the 2015 Award.

The award is named after Emil Mosonyi, the founding president of the International Hydropower Association. Professor Mosonyi made major contributions to hydropower during his long career, and the award recognises outstanding contributions to the global hydropower sector.

Hydro Tasmania CEO Steve Davy said Dr Locher was a deserving recipient, noting her 25 years’ experience working on environmental, social and sustainability issues in many contexts. Mr Davy singled out a significant contribution during a three-year secondment to the International Hydropower Association.

“Helen coordinated a multi-sectoral forum with representatives from developing and developed countries, environmental and social NGOs, commercial and development banks, and the hydropower industry,” said Mr Davy.

“She played an instrumental role in bringing diverse and strongly held views into alignment on the structure and content of a globallyapplicable sustainability assessment framework for hydropower development and operation.

“The resulting Hydropower Sustainability Assessment Protocol is now widely used and endorsed internationally, and guides the sustainable development and management of hydropower schemes in many countries.”

Dr Locher’s work with the IHA followed nine years of developing and leading programs for Hydro Tasmania to address environmental and social issues relating to its operations.

More recently, Dr Locher has consulted internationally on significant sustainable hydropower initiatives, often as a team leader, and including undertaking sustainability assessments of hydropower projects around the world.

“I am delighted to accept the reward in recognition of both my own efforts and those of Hydro Tasmania.

“What I have been able to achieve was only possible through the efforts and support of so many others. This award is a great statement about the importance of sustainability both to Hydro Tasmania and to the global hydropower industry,” she said.

In applauding Helen’s recognition, Mr Davy also acknowledged the work of Andrew Scanlon, who led Hydro Tasmania’s environment and sustainability efforts for two decades and played an instrumental role in the IHA’s sustainability initiatives.

The IHA works to build and share knowledge on the role of hydropower in renewable energy systems, responsible freshwater management and climate change solutions. It has members in more than 80 countries, including many of the world’s big hydropower companies.

Entura appointed to deliver feasibility study for innovative pumped storage hydro project S PECIALIST power and water consulting firm Entura has been appointed by Genex Power to deliver a bankable feasibility study for the Kidston Pumped Storage Hydropower Project in North Queensland, Australia.

Situated some 270km North West of Townsville, near the township of Georgetown, the project is located on the site of the historic Kidston Gold Mine. The abandoned mine site contains two large adjacent pits with the potential to act as the upper and lower reservoirs required for pumped storage hydropower generation.

There are currently only three pumped storage hydro schemes in Australia. The Kidston scheme will have an installed nameplate generation capacity of 330 MW and power generated will be sold directly into Australia’s National Electricity Market during times of peak demand.

Commenting to the market on the appointment of Entura, Genex’s Managing Director Michael Addison said: “Entura is

a world leader in the planning, design and construction of hydro power stations and we are pleased to have engaged them to manage the bankable feasibility study process.

“Initial engagements between Genex and Entura have been very positive and we look forward to working with the Entura team, which has already indicated scope for improvements on the initial project design. The Genex Board will work closely with Entura to deliver a bankable feasibility study on budget and is on track to complete the work by 30 June 2016.”

Entura will partner with leading Chinese power and design consultants HYDROCHINA in the feasibility phase of the project. In November 2014 the two firms signed a Memorandum of Understanding to cooperate on the development of opportunities in the energy and water sectors.

Entura’s Managing Director Tammy Chu said: “As part of Hydro Tasmania, Entura brings a utility-owner perspective, deep local experience, regulatory knowledge and optimisation capability to the Kidston Pumped

Dam refurbishment project wins project management award

H

YDRO Tasmania has been awarded the Tasmanian Project of the Year in the Construction/Engineering category by the Australian Institute of Project Management.

The Award was presented at a function in Hobart recently and recognised excellence of project management for the refurbishment of Rowallan Dam in Tasmania’s north.

Rowallan Dam is a 43-metre high earth and rock-fill dam on the Mersey River in Tasmania’s north, built in the period 196467 and commissioned in 1968. The dam is comprised of two embankments separated by a central concrete-lined spillway.

The condition and performance of the dam were reviewed in 2011 as part of a planned program of risk assessment across our entire asset base.

This review found the dam’s performance was consistent with expectations for a dam of its design, construction and age. However, improved understanding of the dam’s risks meant Hydro Tasmania was able to reduce risks that were unforeseen in 1968.

The two-stage refurbishment involved strengthening of the spillway walls and improving the capacity of the dam to withstand large floods. Work was conducted over the summers of 2013-14 and 2014-15.

It was the first time that a project of this complexity has been successfully undertaken on a live dam in Australia.

The work on Rowallan Dam cost $13.4 million over three years, and the project is part of Hydro Tasmania’s rolling 10-year asset management plan.

Across a century of hydropower development Hydro Tasmania, Australia’s largest water manager, has constructed 55 major dams, 30 power stations, and hundreds of kilometres of man-made waterways to direct water to storages and power stations. Many of these assets were world firsts when they were built and continue to provide outstanding service to this day.

Sustainably managing our dam portfolio is a priority for Hydro Tasmania: that is, we manage for the future. We undertake regular and planned risk assessments for all our infrastructure. As these assets age we continue to monitor them for efficiency and safety and we invest to ensure they remain fit for purpose and provide ongoing service for the foreseeable future.

Planned maintenance and upgrades help to retain our world-class standards. Our major project schedule ensures the electricity supply is reliable and maximises power generation, ensuring Hydro Tasmania remains Australia’s leading producer of renewable energy.

Minister for Energy celebrates business successes with Horizon Power

T

HE Minister for Energy, the Honourable Dr Mike Nahan MLA, joined Horizon Power to celebrate the completion of two projects which will bring the organisation one step closer to achieving a $100 million reduction in its subsidy by 2018.

Minister Nahan officially opened Horizon Power’s relocated control centre at its Bentley office and joined staff and representatives from Contract Power in marking the completion of the first stage of the Mid West Conventional Generation Project.

The relocation of the control centre from Horizon Power’s Karratha base to Perth is predicted to save approximately $800,000 a year. The delivery of six new power stations in Cue, Meekatharra, Yalgoo, Wiluna, Sandstone and Mount Magnet and more flexible contracting arrangements with the independent power producer Contract Power are together forecast to save millions of dollars over the 10year life of the contract.

As part of its strategic review in 2013, Horizon Power committed to reducing its operating subsidy to become a low cost and sustainable business. Horizon Power has made strong progress in achieving this reduction, with $203 Million savings already included over the forward estimates period to 2018/19.

One of Horizon Power’s Board Directors Rosemary Wheatley also attended the celebration.

“Projects such as these show that as a business we are delivering on our promise to save taxpayers money, but have not wavered from the commitment to provide our customers with safe and reliable power supply,” said Ms Wheatley.
