Official opening of Musselroe Wind Farm T “The RET is a key driver for investment in wind farms as well as for the refurbishment and upgrade of our existing hydro plant. Its continuation will support investment and job creation throughout rural and regional Tasmania and Australia, as well as contributing to energy security and greenhouse gas abatement in the Australian energy sector.”

Musselroe Wind Farm is operated under a joint venture between Shenhua Clean Energy (SCE) and Hydro Tasmania, an entity known as Woolnorth Wind Farm Holdings. The joint venture also operates two wind farms in northwest Tasmania at Studland Bay and Bluff Point.

SCE owns a 75 per cent share in the wind farms, and Hydro Tasmania retains 25 per cent.

“With the planned operational life of the wind farm being 25 years, we will remain part of the north-east community for years to come and will provide an ongoing source of support to the economy of the region,” said Stephen Ross, General Manager of Woolnorth Wind Farm Holdings.

Mr Ross said the relationship between Shenhua and Hydro Tasmania is significant because it is the first investment by a Chinese company in renewable energy generation in Australia.

“We have been delighted with the support and the investment of our shareholders. We look forward to continuing to work with Shenhua Clean Energy and Hydro Tasmania on future renewable energy projects,” he said.

The Musselroe Wind Farm has been generating electricity into the Tasmanian grid since April 2013 and the full 56 turbines have progressively come on line since that time.

ASMANIA’s biggest wind farm was officially opened receently by Premier Lara Giddings.

The 168 megawatt Musselroe Wind Farm in Tasmania’s north east is now generating enough energy to supply the needs of up to 50,000 homes, equivalent to the residential power needs of Burnie and Devonport combined.

Importantly its operation will prevent 450,000 tons of CO2 being released into the atmosphere each year.

Construction of the $394 million wind farm began in December 2011. Hydro Tasmania Chairman David Crean said the project continued Hydro Tasmania’s interest in wind generation which began on King Island in the late 90s and continued with the construction of two wind farms in north-west Tasmania.

“Our involvement in wind has shown it to add considerable value through expanding Hydro Tasmania’s generation portfolio,” said Dr Crean.

“It also complements perfectly our hydro capability, providing the renewable energy certificates to meet our retail obligations and generating profit and value for our shareholders, the people of Tasmania.”

Dr Crean said as Australia’s largest renewable energy generator Hydro Tasmania was committed to strategic new investment in renewable energy as well as investment on existing assets.

“The Musselroe project has only been made possible because of the national renewable energy target (RET), which began in 2001 under the Howard Government and has been supported by successive federal governments since.

Hydro Tasmania project wins national innovation award A Hydro Tasmania project maximising the renewable energy potential of King Island has won the 2013 Innovation Award from the Energy Supply Association of Australia.

Each year, the Energy Supply Association of Australia (esaa) honours member businesses taking the lead on advancing new projects and good corporate citizenship. The Innovation Award recognises energy businesses making the industry more sustainable, efficient and cheaper to run.

Hydro Tasmania’s King Island Renewable Energy Integration Project (KIREIP) uses a range of renewable and conventional technologies to reduce diesel consumption for power generation on the island.

KIRIEP is a hybrid power system, comprising 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 the island, even during lulls in the wind or when the sun isn’t shining,” said Project Director Simon Gamble.

“When conditions are right, KIREIP delivers all of King Island’s power from renewable sources, reducing the cost of providing electricity to the island.”

The judging panel said: KIREIP impressed our judges as a world-leading approach to harnessing the full capacity of renewable energy. The project also has the potential to be replicated in remote areas to reduce reliance on diesel and the cost of supply.

KIREIP is an initiative of Hydro Tasmania

Interface and is being developed with the assistance of the Australian Renewable Energy Agency and the Tasmanian Government. Read more on the project website.

Precipitator electrode project in full swing at Loy Yang

W

ORK on the Stage 1 precipitator electrode replacement project is progressing well.

The project aims to rectify an electrode design fault and improve the unit’s dust collection performance said Precipitator Project Support Officer, Janice Auchterlonie.

Electrode failures caused by the design defect had resulted in the forced reduction of generation to comply with dust emission licence requirements.

“Electrodes in precipitator flow 2-EPF-5 will be replaced as part of the project, which has a total cost of approximately $2.2 million,” Janice said.

The electrostatic dust precipitators (EDPs) consist of 12 individual flows per generating unit, equating to 24 individual flows in Stage 1 of the power station.

According to Janice, seven of these had been fully refurbished between March 2009 and January 2014, with the eighth flow refurbishment commencing this month. This will leave us with a further 16 still requiring refurbishment.

“The precipitators extract dust from the boiler flue gases before they exit via the chimney,” said Janice.

“The electrodes inside each flow provide the mechanism to capture then extract the dust.”

Unit 1 and 2 collecting electrodes (CE) were progressively cracking and failing due to a

design fault where the CE plates join the anvil bars with Huck bolts – a defect not present on Units 3 and 4.

“Replacement requires a significant amount of work. The roof of the precipitator casing needs to be removed before each of the electrodes is lifted out via a 100 or 200 tonne

crane.”

Janice said that substantial structural beam damage had been encountered in previous upgrades due to the ingress of air through holes in the gas-tight roof.

“The structural beams are repaired or replaced as necessary, and the gas-tight roof is replaced entirely to prevent further damage to the structure,” she said.

Works currently underway will see 2-EPF-5 upgraded by 30 June 2014.

“Lend Lease has very successfully refurbished the seven precipitator flows between March 2009 and January 2014.

“They have been on time, on budget, with the required quality standards met and with a very high safety performance,” said Janice.

Each upgrade costs approximately $2.2 million, requires a minimum of five months lead-in time and takes around four months to complete.

Approval was recently granted for a further two upgrades in 2014/15, starting with 1-EPF-2 in July 2014.

Mid West Energy Project - Southern Section

W

ESTERN POWER is pleased to announce that construction of the first of the steel lattice towers has commenced on the Southern Section of the Mid West Energy Project (MWEP).

R

ESIDENTS around Binda Bigga are set to benefit from a more reliable and secure electricity supply as Essential Energy continues work on the fifth and final stage of a major electricity network upgrade.

This follows on from the demolition already underway on the old “cricket-wicket” style line, which was built in the 1970s, and the construction of access track upgrades is underway to provide access for heavy vehicles to all tower sites and provide facilities for dieback and biosecurity control.

Project description Western Power’s proposal consists of a new double circuit 330 kV transmission line between Pinjar and the future Eneabba terminal substation location; an existing Neerabup Pinjar 330 kV line conversion; a new 330/132 kV terminal at Three Springs; and, a new double circuit 330kV line being built by Karara Mining between Eneabba and Three Springs terminal. To connect to this new infrastructure, Karara Mining are building a new double circuit 330kV line between Three Springs and Koolanooka and then a single circuit 330 kV line to the Karara mine site.

A number of mining projects are actively being pursued in the Mid West region that will have significant impacts on total electricity demand. In particular, Karara Mining Limited (KML) is developing a mine around 100km east of Three Springs. KML is currently constructing a double circuit 330kV transmission line between Eneabba and its Karara mine site, made in conjunction with the State Government’s funding commitment for the Mid West Energy Project (southern section).

Western Power is also in advanced discussions with Asia Iron’s Extension Hill mine. Asia Iron is seeking connection at Three Springs once MWEP (southern section) is complete.

The additional transmission capacity provided by MWEP (southern section) will overcome current network constraints and allow the proposed connection of future mining and other loads at Three Springs, and facilitate the connection of generation in the Mid West.

The MWEP (southern section) transmission augmentation provides a broad economic benefit to the state of Western Australia and net market benefits to those who consume, produce

or transport electricity in the SWIS. Current plans are that the double circuit section of the line will initially be operated with one circuit at 132kV and the other at 330kV. When additional capacity is required to meet Mid West mining loads or additional generation, the line can be operated with both circuits at 330kV for a relatively modest additional cost.

Rural properties receive power boost R

URAL properties to the north of the Oberon area will soon have a more reliable and sustainable power supply thanks to an Essential Energy network upgrade.

Regional manager South Eastern, Phillip Green, said crews had been working in the area since early November, upgrading powerlines and replacing power poles.

“The powerline that runs from O’Connell to Lowes Mount plays an important role in the distribution and security of the electricity supply throughout the rural areas north of Oberon,” Phillip said.

“This section of powerline has been servicing the community since the 1950s and needs to be replaced to meet future power demands in the local area.”

Over the course of the project, Essential Energy crews will replace 9.3 kilometres of ageing steel powerline with stronger, higher capacity aluminium cable.

The project also includes the replacement of 40 power poles, 23 pole cross-arms and associated equipment.

Network upgrade nears completion

Essential Energy is advising residents that some planned power supply interruptions will be necessary to allow crews to work safely on the network.

“All customers affected by the scheduled power supply interruptions will be notified in advance,” Phillip said.

“Additional crews from the Bathurst and Blayney depots will also be on hand to help the team from Oberon complete the project in as short a time as possible.”

While this project is underway, crews will also be trimming vegetation to maintain safe clearances between trees and powerlines.

Weather permitting, Essential Energy expects to complete the upgrade by June 2014.

“We would like to thank the local community for its patience while we work to deliver a safe, reliable and sustainable electricity supply to our customers,” Phillip said.

Other than at the substations along the route, there will be no changes to the new line as a result of this.

The alignment of the southern section minimises the environmental and social impacts by maximizing the power transferred along the corridor, making efficient use of the transmission line corridor which has been secured for this project.

Local crews commenced work on the final stage of the project in mid-October 2013, including upgrading a further eight kilometres of high voltage powerlines and replacing 40 power poles between Blanket Flat and Bigga Village.

The last stage also includes the installation of two new transformers in the Bigga Village, which will ensure the electricity network meets current and future energy demands.

Regional manager South Eastern, Phillip Green, said the project was one of the largest network upgrades undertaken across the region.

“Most residents would be aware that our crews have been working steadily on this project over the past four years to replace the ageing equipment on the network,” Phillip said.

Essential Energy teams have already upgraded more than 44 kilometres of powerline, replaced 259 power poles and 10 new transformers have been installed.

“Crews from Goulburn and Braidwood have joined the local Crookwell team to help finish the final stage,” Phillip said “All going well, crews expect to complete the project by early April 2014, weather permitting.”

Essential Energy is advising residents that some planned power supply interruptions will be necessary to allow crews to work safely on the network.

“All customers affected by the scheduled interruptions will be notified in advance,” Phillip said.

“We can’t thank the local community enough for their support and patience while this project nears completion.”

Major network upgrade to benefit Eugowra L

OCAL Essential Energy crews will be kept busy over the next 12 months as they work to deliver a major electricity network upgrade east of Eugowra that will ensure a more reliable and sustainable power supply for the rural community.

Over the course of the project, crews will replace more than 15 kilometres of ageing copper powerline along the Canowindra/ Eugowra Road from Namami Lane to Evelyn Street in Eugowra.

The high voltage powerline will be upgraded with stronger, high capacity aluminium cable.

Regional manager South Eastern, Phillip Green, said this project was one of the largest network upgrades happening across the region this year.

“The powerline along Eugowra Road plays an important role in the distribution and security of the electricity supply throughout the rural areas east of Eugowra,” Phillip said.

The project also includes the replacement

of 38 power poles and 100 cross-arms and associated equipment.

To help minimise the impact of the work on the community, where possible, Essential Energy will utilise live line teams who are trained to work safely on the network while it is energised.

“Additional crews from the Orange Depot will also be on-hand to help the team from Canowindra complete the project,” Phillip said.

Essential Energy is advising residents that some planned power supply interruptions will be necessary to allow crews to work safely on the network.

“All customers affected by the scheduled power supply interruptions will be notified in advance,” Phillip said.

Weather permitting, Essential Energy expects to complete the upgrade by June 2014.

“We would like to thank the local community for its patience while we work to deliver a safe, reliable and sustainable electricity supply to our customers,” Phillip said.

Bushfire-resistant power poles provide energy security for Peninsula

P

re-stressed concrete power poles will boost energy security to the Forestier and Tasman Peninsulas after last year’s bushfires caused a lengthy electricity outage in the area.

The new fire-resistant poles will provide back-up power supply after more than 750 poles were destroyed in the major bushfires of January 2013.

Aurora Energy crews restored power supply to all customers within two weeks of the fire last year by rebuilding one of the two wooden pole lines feeding the Peninsulas. After lengthy research and a wait for an end to wet weather, the second feeder line is now being constructed south of Dunalley using the new fire-proof poles.

Chief Operating Officer for Distribution Warren Batchelor inspected the installation of the new poles with journalists today.

“We continually trial new technologies to improve the performance and resilience of the distribution network and the second Dunalley feeder line was a chance try out fire-resistant concrete poles,’’ Mr Batchelor said.

“If a similar bushfire occurred again, these fire-retardant poles will enable a faster restoration of supply, providing comfort to customers in places such as Murdunna, Sommers Bay, Eaglehawk Neck, Nubeena, White Beach, Saltwater River, Slopen Main and Port Arthur.

“A lot of new technologies come at a price premium and Aurora is conscious of the costs we pass to customers because selecting technologies is always a trade-off between performance and cost.’’

Mr Batchelor said that a separate Aurora tender for Tasmania’s main electricity pole supply contract was in the final stages of evaluation.

Aurora Energy maintains about 190,000 wooden poles with an average life cycle of 55 years, plus 30,000 poles made of other materials.

Varley Group to Produce Terex Crane Borers to Suit Any Job

T

HE company, Terex Utilities Inc based in Watertown, South Dakota is the largest producer of crane borers and elevating work platforms in the USA and possibly the world. Their expertise and mass production has been available in Australia through Telescopic Tower Enterprises for the last seven years but is headed for a larger and more extensive promotion through the Varley Group.

Earlier this year the Varley Group, well known for their diverse industry range in special vehicles, aviation, defence, power generation and ship services acquired the business of Telescopic Towers and with Terex backing intend to lift the presence of the equipment range to a new level of sales and service. In particular the group will be holding stock of several models of crane borers and elevating work platforms to ensure early delivery at very competitive price levels. This will be backed by Australia wide service.

The original operators of Telescopic Towers, Geoffrey Eberhard and Tony Newton have moved to the Varley Group at Virginia in Brisbane to ensure a smooth transition with existing clientele.

The Terex manufacturing business was inspected by the Varley Managing Director, Jeff Phillips and General Manager of the Varley TTE Division, Pierre Sidorow earlier this year and considered to be a model of excellence due to intensive quality assurance programs. Most impressive was the ability to produce a large range of models to suit any job mounted on trucks or tracks.

In Australia there are several different models of crane borers operating and the diversity can be seen from the different models and the options. The most interesting crane borer is the unit recently supplied to Electrical Connection Services being a combination 15m crane borer with the optional snap-on bucket with hydraulic levelling, all mounted on a track carrier. This unit operating in rough terrain firstly with the crane borer and then the alternate use of an elevating work platform has proven to be a very versatile combination.

On the smaller side the Terex crane borers have the 4000 series with sheave heights from 12.8m to 15.4m all suitable for 4 x 2 or 4 x 4 trucks, ideal for operating in suburban areas where roads might not be quite so wide and manoeuvring space limited. All the smaller units still retain the powerful 16,000Nm auger motors needed

for efficient boring.

The next size up in the range is the 6000 series with sheave heights from 15.6m to 18.3m. This is the range generally preferred by the power authorities and most of the Terex models operating here are in that range. The C6000 series can be configured with the standard rear mount or if the truck is also designed for use with a jinker to carry poles then the C6000 Series would be front mounted. Several truck models including Mack, Hino, Isuzu and Volvo have been fitted with the C6000 units.

Operators who need even larger crane borers usually opt for the Terex General series with sheave heights from 16.2m to 29.1m. The larger crane borers are generally fitted with the Terex 19,000Nm auger drive.

All Terex crane borers come with tilting pole grabs of various sizes to handle poles from 310mm to 730mm. The pole claws can operate from the end of both the first and second booms with an easy change over facility to maximise the drilling range.

Terex have a patented insulated fibre glass third boom on all their crane borers providing an additional level of safety when operating near live wires. The Terex crane borers are equipped with either Robway or 3B6 Load Monitoring Systems which provide a digital readout and control of allowable loads.

In addition to the crane borers, Terex also manufacture the Reedrill pressure drillers for maximum drilling ability.

There are three models available: the 330 with a torque of 71,200Nm and a drilling depth of 6m; the 650 with a four speed gear box and a drilling depth up to 15m and the 800 model with a torque of 102,000Nm, a drill diameter of 2,48m and a depth of up to 29m Telescopic Towers welcome inspection of their units operating at any on the many locations throughout Australia and a call to Geoffrey Eberhard on 0413 225 979 is the quickest way to arrange a quotation and demonstration of the units.

Brisbane, Queensland – Friday May 24th, 2013: The Varley Group of companies announces the acquisi on of Telescopic Tower Enterprises Pty Ltd and its entry into the power u li es, crane borer and eleva ng work pla orm industry. TTE is a Brisbane based company that is the exclusive Australian, Papua New Guinea and New Zealand dealer for USA company TEREX vehicle-mounted Eleva ng Work Pla orms (EWP’s), Crane Borers and Cable Placers.

Sales of products and services extend across Australia and globally. Varley is broad-based with recogni on in a diverse industry range including avia on, defence, power genera on, rail, ship services and specialised vehicles.

Enquire on our Massive Range of Crane Borers Terex C4050: This 15m combina on crane borer and EWP opera ng on tracks is most versa le. Owned and operated by Electrical Connec on Services in NSW, the unit digs, erects poles and with the EWP op on can service and dress poles in the hard to reach rough terrain areas.

Terex C4050 on Mercedes Atego 1629 4 x 4 This 15m crane borer can be mounted on a 4 x 4 truck for work in suburban areas where the roads are narrower than usual and manoeuvring space limited. It has the full 16,000Nm performance of its big brothers.

Terex C6051 5/10 tonne model is the most popular model in the Terex fleet and can be mounted on the truck at rear for standard opera ons or at the front as illustrated here when used in conjunc on with a pole jinker for carrying the poles with the unit.

Terex C6060 18m 5/10 tonne The next size up is the 18m sheave height model which can be fi ed with the Terex 19,000Nm auger motor for crashing through hard rock in a hurry. This model is a real workhorse and several are opera ng in Australia very efficiently for their owners.

The Terex General Series up to 29m sheave height when the job calls for top level performance. These models are unsurpassed for big performance when it is really needed.

New standby generators deliver improved power reliability to Strahan PowerTek Design Portable Aurora Substation

R

ESIDENTS of Strahan will experience much improved reliability in their power supply following the placement of large, remotely controlled generators in the West Coast town.

The solution, which utilises new, mobile generation plant and high tech communications equipment, will greatly reduce the duration of power outages to Strahan, which has had a history of poor electricity reliability.

Aurora staff will be meeting West Coast Councillors during their regular Council meeting in Strahan to provide an update on the generators, and to give a demonstration of their operation.

Non Network Solution Manager James O’Flaherty said the new generation equipment would be welcomed by the town’s 620 customers and business owners who cater for an influx of tourists each summer.

“Aurora has proposed a unique solution for a particular problem that has resulted in the reliability of electricity supply to Strahan residents being below acceptable standards for many years,’’ Mr O’Flaherty said.

“Until recently, Strahan’s power supply has been via a single, 33km long power line from Queenstown, which has been vulnerable to lightning strikes, falling trees and wild West Coast weather.

“This has resulted in an average of four

P

Above: James O’Flaherty (Aurora Energy), Andrew Fraser (Aurora Energy), Mayor Robyn Gerrity (West Coast Council), Cr Lindsay Newman (West Coast Council), Cr Shane Pitt (West Coast Council), Cr Phil Vickers (West Coast Council) and Cr Al Medwin (West Coast Council) outages a year affecting all Strahan residents, some of which have been lengthy. The single source of supply has also required Aurora to ‘disconnect’ the entire town in order to do any planned maintenance of the 33km power line from Queenstown.

“Our solution to embed alternative generation in Strahan as a contingency for

power outages is highly cost effective and will bring confidence to residents and businesses about power supply.’’

Mr O’Flaherty said the permanent substation and two high capacity transportable generators had already been commissioned and trialled manually, and were now remotely controllable from Aurora’s Distribution Operations Room in Hobart. Later this year the operation will be automated.

“As well as the benefit to the people of Strahan, this solution is also a financial positive for Aurora, paying off the equipment’s capital cost within a few years due to the avoidance of customer guarantee payments and potential fines from the Australian Energy Regulator,’’ Mr O’Flaherty said.

owerTek Australia is a privately and wholly Australian owned company, specialising in a wide range of electrical manufacturing and supply of equipment to mining and heavy industry.

Designing and manufacturing the five portable containerised substations for Aurora was a proud and satisfying achievement for us by helping our local Supply Authority look after the needs of Tasmanians.

New energy hub for Gundagai

Gundagai Zone Substation

E

SSENTIAL Energy crews are continuing to work on constructing a new zone substation in South Gundagai which, once complete, will strengthen power supplies to the local area.

The project is part of Essential Energy’s ongoing commitment to upgrading and improving electricity services for regional and rural communities across NSW. Regional manager for the South Eastern region, Phillip Green, said the new zone substation would replace the two existing zone substations located at South and North Gundagai.

“The original zone substation at South Gundagai was built in 1928 as part of the Burrinjuck Hydro- Electric development, which once provided electricity to Murrumburrah, Cootamundra, Junee, Gundagai, Tumut, Wagga Wagga and Young,” Phillip said.

“Over the years our local teams have worked hard to keep the facility in peak condition but due to the age of some of the equipment the site now needs to be upgraded to ensure we can continue delivering a reliable electricity supply to the local community.”

The project will bring together Gundagai’s two existing zone substations into one new facility to be located on Luke Street - adjacent to the old South Gundagai zone substation.

The new zone substation will be the hub for Gundagai’s three main high voltage powerlines and will include two new transformer bays, a new nine panel 11,000 volt switchboard and switching gear as well as a new control room. It will be surrounded by a 3.6-metre-high security fence.

The project is now approaching the final

ElectraNet’s New Waterloo Substation Energised

stages, which includes work on the powerlines immediately outside the newly constructed facility to prepare for the transfer of the power supply from the old substation.

Work on the new zone substation is expected to be complete by mid-April 2014, weather permitting.

Essential Energy is advising the community

TransGrid on track to deliver additional $30m of savings to electricity consumers TransGrid has commenced the provision of Network Support and Ancillary Services (NSCAS) to the National Electricity Market (NEM) with the commissioning of a new voltage control device at Yass Substation.

ONSTRUCTION of the new Waterloo substation on a site adjacent to the old Waterloo substation started in October 2012 and the new substation was energised in October 2013, according to schedule.

The new Waterloo substation ensures that transmission network reliability for the MidNorth region is improved and is an integral part of the South Australian high-voltage transmission network. It connects four existing 132 kV transmission lines to Hummocks, Mintaro, Waterloo East and Templers substations.

Valuable assistance was received from the community on sourcing required construction materials locally, identifying areas for storage, as well as local knowledge of soil and weather conditions. This input was useful in helping ElectraNet make key decisions associated with the construction activities.

Decommissioning of the old Waterloo substation site is currently underway and will be complete in Quarter 2 this year. Most of the equipment will be removed from the old site with SA Power Networks retaining a small amount of live equipment within a fenced yard in the old site.

On-site road restoration Throughout the project, ElectraNet was guided by Council and the community, who have expressed a desire for road conditions to be monitored, when identifying key routes for construction traffic to the site.

Page 10 - Australian Power & Energy News

This input has resulted in thorough planning and identification of appropriate roads for construction traffic, maintenance of safe road conditions throughout the construction period and roads being restored to their original condition or better at the end of construction.

Milde Road near the substation site has been improved, as part of ElectraNet’s contribution to making the roads safer for the community in Waterloo.

Minor upgrades were also made to Main Road, the entrance to Waterloo Quarry and the turn off to Manoora from the Waterloo-Marrabel Road. Potholes and verges that would otherwise have deteriorated and posed risks to local road users were fixed as part of this initiative.

Community initiatives ElectraNet seeks to support communities in areas where transmission assets are located, through initiatives that have widespread benefit and contribute to improvements in community life and environmental sustainability.

ElectraNet is proud to support the Waterloo Country Fire Service (CFS) through the purchase of a mobile generator. This mobile generator will provide the power for lighting and equipment in times of emergency or during field exercises, providing a safer environment for CFS volunteers. This community benefit sponsorship of $12,500, combined with other funds raised by the CFS Brigade, will enable the acquisition of the generator in early 2014.

that there will be an increase in heavy vehicles and construction equipment around Luke Street for the duration of the project.

“Last year, Essential Energy local crews upgraded more than three kilometres of the low voltage electricity network and replaced around 50 power poles in town to improve supply reliability and cater for growth,” Phillip said.

This is the first in a series of similar voltage control equipment to be commissioned over the next two months at TransGrid’s Yass and Murray Substations. TransGrid secured the contract to provide these NSCAS services to the Australian Energy Market Operator (AEMO) after a competitive tender process.

“The first device was delivered well ahead of schedule and is providing significant savings to the National Electricity Market,” said Gerard Reiter, TransGrid’s Executive General Manager, Capital Program Delivery.

“By fast-tracking the delivery of the voltage

control devices and making them available to AEMO, we expect to provide total savings to the market in the order of $30 million over the next 5 years.

“These benefits are expected to ultimately flow through to electricity consumers in NSW and the ACT. “TransGrid is extremely pleased to be able to provide these savings to the market which demonstrates both our ability to operate successfully in the competitive environment and deliver commercial benefits and savings to the market and consumers,” Mr. Reiter said.

NSCAS are non-market ancillary services acquired by AEMO or Transmission Service Providers, to maintain power system security and reliability and to maintain or increase the power transfer capability of the transmission network.

New Generation Battery Analysis B

ATTERY Load Testers have been around for many years but there has not been any significant improvement to the design since inception, some up to 20 years ago.

The shortcomings of most battery load testers are: • Insufficient load current for many applications requiring an additional load unit, • Excessive weight giving rise to WHS concerns due to the age of the technology.

• High cost of repair and maintenance also due to the age of the technology.

New Generation Battery Load Analysis The new DV-Power BLU200A Battery Load Unit will soon be available from Pacific Test Equipment and will be featured at the forthcoming TechCon 2014 exhibition in Sydney.

With the DV-Power unit, measuring battery capacity is based on a stateof-the-art technology, using the most advanced power electronics solutions with coolers and fans integrated into device.

The BLU200A provides that the discharge current is a true DC ripple-free current up to 200 Amps, for 10 – 300 V battery systems.

The BLU200A instrument has an internal memory for storage of results, a flash drive port and USB cable for simple data transfer. All measurements are time and date stamped. A keyboard and graphical 4.3” touch-screen display is included for easy navigation.

Overcurrent and overheating protection is installed, as well as protection against fan failure. An emergency stop button, external alarm trigger and galvanic keyboard isolation are included.

Ethernet interface is an option. Using DVWin the results can be arranged and printed for a report in a selectable format as an Excel spreadsheet, PDF, Word or ASCII format. Importing other types of data format (jpeg, png, doc) into standardized DV-Win report is provided.

Exporting the numerical and graphical results from DV-Win into customizable report is supported. Additionally, the software provides a possibility of setting extra parameters (cell, capacity, time) for alarming and ending the test.

Connecting the BLU200A to Battery Set Using two sets of cables, the device can be connected to any battery test object.

The connection to the battery is made using two- contact clamps.

The diagram below shows the connections for a discharge test of an eight-cell battery system wired in series and parallel (for example 24 V systems with 6 V batteries).

The test setup time is minimized and the test can be started very quickly once the battery system voltage is detected and discharge current entered.

For best results it is recommended that the discharge test is preceded and followed by full battery charging.

Above: Battery Load Unit – BLU series Right: Battery Voltage Recorder unit Below: Connecting to the BLU200A

Compatible with DV-Win Software

Higher Current – Lower Weight Compared to its nearest rival, the new DV-Power unit can discharge 80% more current but is 30% lighter, weighing just 14.5kg! Another competitor can get within 54% of the DV-Power’s load current but will bust your back with a massive 32kg weight penalty!

Discharges Greater than 200 Amps If discharging rate higher than 200 A is required, two or more BLU200A units can be connected in parallel. The discharging can be conducted according to constant current, constant power, constant resistance and selected load profile.

DV-Win Software With the included DV-Win software, a test can be performed and observed from a user’s PC, and the results can be obtained directly on the PC. Communication between the BLU200A and the PC is normally achieved via the USB cable.

Battery Voltage Analysis To compliment the Battery Load Unit, DV-Power is also releasing the Battery Voltage Recorder (BVR) This hand-held unit is intended for monitoring battery voltages and temperature while battery is either connected or disconnected from the network. It can be used during a battery charging/discharging process as well.

When used in combination with BLU200 it serves as an efficient supplement to the battery capacity testing.

Electrolyte Density The BVR can also provide data on the density of the electrolyte by communicating with an external

hydrometer over an infrared (IR) link. An additional feature is the compatibility with the cell tags enabling cell recognition over Radio Frequency Identification (RFID).

Easy to use This BVR is simple and easy to use with the possibility to systematically memorize the results of each measurement. All measurements are time and date stamped.

It also has the possibility of fast and easy data transfer and storage over USB cable.

Future analysis of data transferred to a PC is possible by using DV- Win set of software applications.

This instrument is equipped with keyboard, graphical 3.1” colour touchscreen and voltage measurement completion indication signal.

The BVR uses the same DV-Win software as the BLU200 allowing the results to be presented as tables and graphical curves and bars. They can be arranged and printed for a report in a selectable format as an Excel spreadsheet, PDF, Word or ASCII format. Additionally, importing other types of data formats (jpeg, png, doc) into standardized DV-Win report is provided, as well as exporting the numerical and graphical results from DV-Win into customizable reports. Also, the system application provides an alarm notification when detecting cells with voltage level lower than the threshold.

DV-Win enables a user to retrieve historic data on every individual cell.

Powering Parramatta:

Power to grow for Sydney’s Second CBD

$300 million Parramatta CBD Electrical Upgrade includes: • establishment of West Parramatta Zone Substation

O

NE OF THE largest and most complex projects Endeavour Energy has ever undertaken – the network upgrade of Parramatta’s Central Business District – is almost complete.

“We’re investing more than $300 million in this upgrade as part of our commitment to providing residents and businesses in Parramatta with the most reliable electricity supply possible,” said Endeavour Energy General Manager Network Development Ty Christopher.

Mr Christopher said the investment was driven by both the burgeoning growth in the CBD and ageing electrical assets.

“Parramatta is the economic capital of Greater Western Sydney, and is the sixth largest CBD in Australia.

Page 12 - Australian Power & Energy News

“Based on past trends in employment growth, Parramatta City Council forecast that employment in the CBD will increase by an extra 30,000 people by 2025.”

In response to this forecast employment growth, Mr Christopher said an Endeavour Energy study of the future electricity needs of Parramatta in 2002 found that electrical load for the area would exceed 300MVA within 40 years.

“We were also concerned about the condition of oil-filled transmission cables that supplied the CBD and the risk they posed to this region in the event of a failure.

“We developed an integrated paln to maximise the good alignment between growth and renewal needs.”

Mr Christopher said one of the important aspects of the project was the extensive community consultation undertaken in developing the plans and throughout the construction process.

“The Parramatta CBD attracts a large number of visitors who undertake a variety of activities such as shopping, dining, recreation, and culture. It’s also a major traffic thoroughfare.

• establishment of East Parramatta Switching Station • establishment of a new Granville Zone Substation • redevelopment of Camellia Transmission Substation • renewal of Guildford Transmission Substation • new underground 132kV transmission cables between West Parramatta Zone Substation and East Parramatta Switching Station • new underground 132kV transmission cables between Guildford Transmission Substation and West Parramatta Zone Substation • new underground distribution works within the Parramatta CBD.

“We recognised from the outset of our project that it would be important to consider the views of the local residents and businesses impacted by our works, including traffic and pedestrian access within the CBD. “We sought feedback through a number of forums and tried to reach as many people as possible to inform them of our plans and allow for input into each of the respective projects.

“Given the significance of Parramatta as a business centre, we hosted special events to

engage local businesses and the Parramatta Chamber of Commerce with information on our projects.”

Mr Christopher said the comments received were considered and included in the comprehensive environmental assessment for each of the respective projects.

“We aimed to minimise the impact of construction activities on local residents and businesses as we completed each of the projects in the upgrade.”

POWERING PARRAMATTA: POWER TO GROW FOR SYDNEY’S SECOND CBD

$300m+ investment in Parramatta

West Parramatta Zone Substation

$50 million has been invested in the construction of the new West Parramatta Zone Substation. This investment included: • establishment of a 90MVA 132/11kV multi-level zone substation to house 132kV and 11kV GIS switchgear and electrical equipment • installation of communications, protection and control systems • equipment fit out and commissioning of the new substation.

The new West Parramatta ZS uses the latest technology to improve the safety and reliability of electricity supply vital to for a CBD. The substation building was architecturally designed to blend in

with the streetscape and pay homage to Parramatta’s historic past with some of the historical items found on site during construction now placed on display through glass windows forming part of the facade of the zone substation.

Other heritage items of cultural significance discovered during construction were donated to the Parramatta Heritage Centre for preservation.

East Parramatta Switching Station

$24 million was invested to establish the new East Parramatta Switching Station at 140 Macquarie Street, Parramatta. This investment included: • construction of a multi-storey control building to house new electrical 132kV switchgear • installation of protection, SCADA, communication and control systems within the building • relocation and termination of the existing 132kV electricity cables from the existing Union Street switching station to East Parramatta • decommissioning the existing Union Street switching station.

Building design was undertaken in consultation with Parramatta City

Council as the switching station is located in a precinct which includes a mix of residential and commercial buildings.

As a result, a range of glass, composites, cladding and polished stone was used as part of the exterior finish so the façade of the building blended with the multi-storey residential apartment blocks neighboring the site.

One of the biggest challenges for this project was the construction of a 41 metre tall building on a site that was only 13 metres wide and 35 metres long. This meant the planning and sequencing of construction activities were vital to the successful completion of the project, which was ultimately completed ahead of schedule.

West Parramatta Zone Substation As part of a $58 million investment to improve the safety and reliability of electricity supply for the area, Endeavour Energy established the new Granville Zone Substation in Elizabeth Street, Granville to supply 6,000 homes and business in the local area.

The work on this project included the installation of: • construction of a new architecturally designed control building designed to look like a modern two storey house to blend in with the surrounding area • two new 33/11kV 25MVA transformers with the provision for a future third transformer • new 33 and 11kV indoor switchgear • decommissioning of the old Granville Zone Substation including protection of heritage buildings as well as remediation of the site.

Camellia Transmission Substation $16 million has been invested to upgrade Camellia Transmission Substation which is just five kilometres from the Parramatta CBD. The focus of this investment has been to install and commission a 132kV busbar and remove the tail-ended operation of the 3 x 120 MVA 132/33kV transformers.

Each transformer and feeder is now controlled by a local circuit breaker which provides greater operational flexibility at Camellia Transmission Substation for supplying the zone substations and East Parramatta Switching Station in the Parramatta CBD.

The work undertaken included: • construction of a new control building, a new access road and security fencing; • installation of new 132kV and 33kV indoor GIS switchgear, three 120MVA 132/33kV power transformers and four 33kV capacitor banks • new fire and security systems, protection and control and auxiliary equipment • removal of the existing substation equipment and remediation of the site.

The new building has been architecturally designed to blend in with the surrounding area and has substantially improved the visual amenity the substation.

Underground cabling to connect the new and upgraded substations has been an integral part of the overall Parramatta CBD upgrade with over 40 individual projects completed at various locations.

This has included: • 7.8 km of underground cable connecting West Parramatta Zone Substation to Guildford Transmission Substation

Guildford Transmission Substation Originally built in the 1959, the $66 million investment in the renewal of Guildford Transmission Substation was one of the most important cogs in the $300 million Parramatta CBD upgrade.

This tranmission substation, located in an industrial area in McCredie Road, Guildford fulfils a critical role in the safe and reliable supply of electricity to the Parramatta CBD.

Underground Cabling

• two new underground 132kV cables connecting West Parramatta Zone Substation and East Parramatta Switching Station • 19 new distribution feeders to connect West Parramatta Zone Substation to the surrounding 11kV CBD network.

This included reconfiguring the existing 11kV distribution network to improve quality of supply • establishment of new switching hubs to improve response times and the capacity of the local network.

T: 131 081 Endeavour Energy workers are proud of the role they played in the recent construction of the new East Parramatta switching station which has been designed to be upgraded to a zone substation to meet the future growth in the Parramatta CBD.

TransGrid takes up the energy challenge with the iDemand Project at its western Sydney headquarters

W

ITH heatwave conditions sweeping the country, it’s more vital than ever before that our electricity suppliers come up with ways to reduce electricity demand and this is a core focus of TransGrid’s future planning.

The operator of one of Australia’s largest high-voltage transmission networks has recognised that even more innovative ways of managing demand for energy supplies are required.

“We are exploring several different areas in demand management,” said Mal Coble, TransGrid’s manager of Network Support and Consultations One of those initiatives is underway at TransGrid’s Western Sydney facility at Eastern Creek, with work having commenced on a hybrid energy system known as iDemand.

Ultimately it’s hoped that the findings from this project can contribute to better management of peak demand.

Information around the outcomes will be offered to research organisations and provide potential for market development in Australia, including the chance for businesses to retro-fit areas of their work-sites with solar capacity.

“It’s important that we practice what we preach, that’s why we are setting this up at our western Sydney headquarters,” he said.

Solar panels (on top of the site car park) will harness solar energy for immediate usage on site, while batteries will store energy during off-peak periods at night and discharge energy to the site during the day.

“Combined with the LED lighting, the total peak demand on site during summer periods is expected to reduce by up to 50 per cent as a result,” Mr Coble said.

The expected savings will be the equivalent of taking almost 40 households off the grid on a typical summer’s weekday and the peak savings will be the equivalent of switching off a similar number of air conditioners during peak demand time at the Eastern Creek facility.

“This is also about putting more information into the public domain about what demand management is and what it can offer. iDemand data and outcomes will be made available on TransGrid’s website,” Mr Coble added.

Above: TransGrid Team discusses the iDemand Project at Eastern Creek

Above: TransGrid towers into its Western Sydney facility at sun rise Below: Work has begun on the carpark site at Eastern Creek

Demand management is a strategy whereby electricity users are encouraged to actively change their use patterns, either by decreasing electricity consumption or shifting use from peak demand periods to off-peak times.

It is considered a vital component in helping to reduce pressure on a network during times of high electricity demand.

“An example of this pressure comes with a very hot day when many homes and businesses immediately. are running air conditioners and pool pumps,” Mr Coble said.

“But it’s not just about finding demand solutions - there are significant environmental pluses of course, through savings on carbon dioxide emissions.”

The primary system includes the installation of 400 kilowatt-hour capacity lithium polymer batteries and almost 100 kilowatts of solar panel capacity.

The infrastructure also includes an IT interface, an integrated hardware system which will provide opportunities for further collaborative research with universities. Realtime data displays linked to the TransGrid website will display the outputs from the solar panels and batteries on site and demonstrate the demand reductions achieved each day.

“We’ll be busy testing all the control regimes including the efficiency of all parts and that includes issues such as how the panels perform in the hottest conditions, if there is any drop-off in performances,” Mr Coble said.

In addition to this iDemand project, each year TransGrid works closely with research bodies throughout the country to run a variety of demand management and demand response programs.

In December, TransGrid claimed the top award in the Best Demand Response category of the Energy Efficiency Council Awards, after combining with EnerNOC last summer (the world’s largest demand response provider) to deliver a demand management project involving more than 80 sites across metropolitan Sydney, including some of the harbour city’s largest energy users.

Construction of the iDemand project is expected to be completed by September of this year, with the data expected to be on display

TransGrid and EnerNOC recognised as leaders in Demand Response energy initiatives TransGrid has added to its list of achievements in 2013 by claiming the top award in the Best Demand Response category of the Energy Efficiency Council Awards.

TransGrid and EnerNOC (the world’s largest demand response provider and leading energy intelligence software company) combined forces last summer to deliver a demand management project involving more than 80 sites across metropolitan Sydney.

This collaboration was responsible for identifying a reduction of about 600kW per site and subsequently the possible reduction of peak demand for the summer of 2012/13 by a total of 48MW, which represents almost 150% of targeted savings.

“You can’t deliver projects of this impact without innovation, teamwork and collaboration between all parties,” said TransGrid Managing Director Peter McIntyre.

Page 18 - Australian Power & Energy News

TransGrid continues to develop innovative demand management programs to help reduce pressure on the electricity network and defer the need to expand network capacity.

TransGrid has spent almost $6.5 million on demand management research since 2009 and more than $20 million on demand response projects. The program dates back to 2006 when first identified by Mr McIntyre.

“Our strong partnership with EnerNOC made it possible for TransGrid to leverage existing relationships with Sydney’s large energy users, to trigger changes in power use when peaks were forecasted,” Mr McIntyre added.

“Without the dedication and expertise of staff from both companies, this success does not happen – I extend my thanks to them and the judging panel for recognising the inspirational work they were responsible for.”

TransGrid has a stated aim of leading the way for Australian transmission companies

Above: TransGrid and EnerNOC win at Energy Efficiency Council Awards in demand response as part of its wider asset investment strategy.

“TransGrid is a proven leader in innovative demand-side management, integrating demand

response into its network planning and development of major projects,” said Christian Weeks, EnerNOC Australia and New Zealand Managing Director.

Downer Opts For Green Power on Wind Farm Construction Phase

D

OWNER construction have opted to use the Green Power Solutions Biodiesel powered generators to power the site office complex on the new Taralga Wind Farm project.

The main site office complex is powered by a 120kva Shindaiwa mobile generator which runs a common rail Isuzu engine that meets European tier IV emission standards and running on the Pro Green Biodiesel makes this generator the cleanest in the country.

Pro Green Biofuels supports Green Power exclusively with locally produced high quality biodiesel that not only is good for the environment by reducing carbon output for every litre used it is also good for the local economy by displacing costly imported fossil fuels.

The Green Power Generator is also remotely monitored offering Downer a better support service and the comfort in that GPS is continually assessing the performance and suitability of that generator.

The Shindaiwa generator is already the most

fuel efficient in its class but if it is identified through the remote monitoring that the site demand has changed then GPS will swap the generator out for a more suitable unit to further reduce site fuel consumption.

By choosing the GPS biodiesel generator Downer is now able to better meet its reporting obligations and some of its own internal KPI`s.

“With the changing form of the construction industry it is important we all adapt to the new way of doing business” said Downers site construction manager Malcolm Moore “and our choice to go with the biodiesel generator was not just a green decision but was influenced by the commercial benefits Green Power Solutions can offer”.

So for the constructors of future renewable energy projects Green Power Solutions can offer carbon neutral temporary site power options and site support service to match so call the team on 039 463 3000 or go to www.greenpowersolutions.com.au for more information.

ActewAGL staff celebrate 25th anniversary

T

HE year was 1988. Australia celebrated its Bicentenary. A first fleet re-enactment hit Sydney Harbour and thousands flocked to World Expo 88 in Brisbane. While, in Canberra Floriade blossomed for the first time and New Parliament House was opened.

With much less fan fare, a group of new staff began their careers at the ACT Electricity and Water Authority, which is now known as ActewAGL.

$8.5m Aurora data centre attracting commercial interest P

REMIER Lara Giddings recently officially opened the new $8.5 million Derwent Park Data Centre, which was built to service Aurora’s data needs as well as commercial hosting space for content providers and carriers seeking to leverage the NBN rollout in Tasmania.

The DPDC is the only facility of its type in the State to offer electricity network backup, connected to separate distribution zones with two backup 650kVa generators.

The duplicated power supply and backup is complemented by advanced cooling, security, and fire suppression systems.

Aurora CEO Dr Peter Davis said the data centre already had 62 server racks in place, with 50 already allocated to Aurora and other customers using the commercial space. As customer demand grows, the data centre has the capacity for a further 70 racks.

Dr Davis also said the data centre offered carrier-neutrality, providing telecommunication customers with access to competitive telecommunication services.

“This is the only purpose-built data centre facility of its type in Tasmania, offering up to 130 serviced racks, duplicated power supplies, back-up generation, and advanced fire, cooling and security systems,” Dr Davis said.

“There are three major customers currently utilising the facility, with the capacity to add another 70 racks to the configuration as customer demand continues to grow.

“The facility’s two separate power supplies and backup generators can operate continuously in the event of a prolonged power outage.

“The cooling system in the data centre includes dry cooler technology that takes advantage of Tasmania’s cooler weather to reduce energy consumption and operational costs.

“This data centre should be the first choice for customers seeking data security and reliability for their critical Tasmanian IT services,” Dr Davis said.

URORA ENERGY’s new $8.5 million data centre will help tap into the opportunities provided by the National Broadband Network.

The Premier, Lara Giddings, recently helped launch the new facility at Derwent Park.

The centre is designed to cater for Aurora’s data needs, while providing commercial hosting space for other technology companies and carriers seeking to take advantage of the NBN rollout in Tasmania.

“The Labor Government is fighting to ensure Tasmania reaps the benefits from the new digital economy,” Ms Giddings said.

“The roll-out of the NBN, the emergence of the digital economy, and our growing relationship with the booming economies of

Power and Water marks Renewable Energy Milestone

YDRO-electric power is now being generated in the Northern Territory thanks to Power and Water’s investment in diverse renewable energy sources.

A micro-hydro generator was commissioned at Manton Dam on 12 February marking a milestone in the history of renewable energy in the Northern Territory.

The project uses an available, renewable resource that had previously not been utilised.

The micro-hydro generator will be registered with the Clean Energy Regulator as an accredited renewable energy power station. It will be the first grid-connected hydro power station in the Northern Territory.

The generator will run 24/7 all year using the environmental flow discharged from the dam and will produce enough energy power four average Darwin homes.

Manton Dam is currently full and spilling so the generator is working at capacity resulting in an even higher than expected 4kW. Charles Darwin University’s Centre for Renewable Energy was involved in the very early stages of the project, exploring the feasibility of hydro-power at Manton Dam. A future stage 2 of the project will aim to use Page 20 - Australian Power & Energy News

the potential of wet season spill from the dam.

Interpretive signage will be installed at the hydropower station explaining its operation to visitors to the site, which is located near the entrance gate to Manton Dam.

Asia are all coming together to create fantastic opportunities for Tasmania in the 21st Century.

“The fast pace of change in this hightech world means that the next generation of Tasmanians will work in jobs that we can barely imagine today, and certainly couldn’t have imagined a couple of decades ago.

“I congratulate Aurora for having the foresight to invest in this facility.

“This $8.5 million investment is both a vote of confidence in Tasmania’s economic future and an important step in enabling and creating the jobs of the future.

“I wish Aurora well in attracting new commercial customers to take advantage of the high tech facilities here, including a huge data storage capacity, dual power supply, and high

level fire, cooling and security systems.”

Ms Giddings said the Government is committed to working with Aurora to continue the roll-out of optic fibre to the door of Tasmanian homes.

“We have put forward a constructive proposal to complete the roll-out quicker and cheaper using Aurora’s power pole infrastructure.

“Securing more optic fibre through the NBN will allow us to attract more data centres to store data from around the world in a safe and secure environment.

“We want to work constructively with the Commonwealth Government to realise Tasmania’s first-mover advantage on the NBN.”

Partnership improves power outcomes for remote communities

Mataranka celebrates bore-dom

T

HE Northern Territory’s Power and Water Corporation has partnered with the Australian Renewable Energy Agency to develop two exciting resources that will help boost the used of solar/diesel hybrid power generation in remote off-grid communities: a Solar/Diesel Hybrid Energy Handbook and supporting modelling software.

Many remote communities depend on diesel generators for electricity.

These generators are expensive to run and costs are difficult to plan for due to the volatility of fuel prices and the challenges distance brings to the supply chain. These two new resources will help to deliver cost-effective, reliable and safe electricity services to remote indigenous communities.

HE small Top End community of Mataranka will experience a high level of bore-dom when two new Power and Water bores are commissioned later in 2014.

Best known as the setting for Jeannie Gunn’s 1902 We of the Never Never, this town of around 400 is set to experience better water quality and higher levels of water security.

Power and Water is currently equipping the two new bores and working in partnership with Aldebaran Contracting to install a new rising main, access road and electrical works.

Located 6km outside the town boundary, the site of new bores will reduce the risk of contamination and improve water quality parameters.

The original bores drilled in 1968 and 1969, are still capable of supplying peak demand and will be maintained as an important back up to the new system.
