Record turnover from our investment strategies; Major growth in our project portfolio across Generation, Transmission & Distribution; An increase of our workforce capacity & capability to over 300 staff; Expansion in our national footprint to operate from 11 locations nationally; Securing of almost every utility panel in Australia;

This is something we should all be extremely proud of; and other firms may be hard pressed to say, the fact we are trusted and privileged to work with almost every utility day in day out, throughout the year.

What truly makes APD experts in the national power and telecommunications industry is our ongoing experience with each network utility, understanding their technical, procedural and individual risk based approaches.

The key to such continued growth, has been by maintaining our strong culture. Combined with our dedication to safety, technical quality and responsiveness – these key strengths have been recognised by our clients.

In respect to safety, our uncompromised commitment to ensuring every individual working for APD Engineering is kept from harm is reflected in our zero LTIFR and TRIFR safety performance.

We are a strong, respected business

and we take great pride in our service delivery.

It’s these basics that underpin our culture and passion to outperform our competition day after day.

As we progress towards 2019, our business is seeing a heightened demand to perform key functions in further large scale renewable energy projects as well as the mining, private and government sectors for infrastructure projects.

MAJOR PROJECTS

ONE of Australia’s largest undeveloped copper deposits, the Carrapateena mine (located about 160km north of Port Augusta), will be an underground operation, with an estimated mine life of 20 years and annual production of 65,000t of copper and 67,000oz of gold.

APD provided the full engineering design to enable the mine site connection, which consisted of 55km of 132kV transmission line, a greenfield 3xPTT (Pernatty) Substation plus augmentation of ElectraNet’s Mount Gunson South Substation.

The new mine substation will consist of three 132kV circuit breakers connected to a single bus arrangement, with three

35MVA 132/11kV transformers, and three outdoor 11kV bays. This plant will be used to facilitate connection of the 55MW mine load.

The transmission line design included the civil, structural and electrical components as well site surveying and construction support.

The substation works included providing design for substation bulk earthworks, civil, structural, primary, secondary and telecommunications. As well as specifications for the procurement of all high voltage plant and ElectraNet’s high-end implementation of the IEC61850 standard.

APD Engineering were recently awarded substation and network connection work on the Warradarge wind farm project by Western Power & Bright Energy Investments.

Warradarge will be the 2nd largest Wind Farm in WA (currently around 100 turbines), with future stages to allow for a capacity of up to 250MW.

The project consists of connection of the proposed wind farm in Eneabba, WA, into the North Country Load Area.

This comprises of seventy three (73)

x 3.43MW wind turbines, collectively amounting to a total DSOC of 250MW with a scheduled in service date of July 2020.

The scope of this project is to produce the detailed design for all HV substation works entailed in connecting the Customer’s Warradarge wind farm to Western Power’s network.

The project involves establishing a new 330kV terminal at Eneabba (ENT) as well as remote end work at the wind farm (WDW) plus Neerabup (NBT) and Three Springs terminals (TST).

The project encompasses all the disciplines relevant to a HV substation including civil, structural, primary and secondary areas.

The works include the integration of the wind farm with Western Power’s existing protection, automation and telecommunications infrastructure.

This was an opportunity for APD Engineering to work across multiple 330kV terminal yards to implement a new mid-west area reinforcement network (MARNET) which has IEC61850 and legacy interfaces.

PROJECTS

IN a partnership between the WA Government, Western Power and local governments, the State Underground Power Program (SUPP) is an initiative that replaces overhead power lines in established areas with underground infrastructure.

THE BENEFITS:

Improve reliability and security of electricity supply for consumers; Enhance streetscapes and visual amenity; Reduce street tree maintenance costs for local governments; Improve street lighting and community safety; and Reduce maintenance costs for Western Power.

BACKGROUND:

Established in 1996, SUPP was designed to improve the reliability of electricity supply after a severe storm in 1994 caused major disruptions to southern parts of Western Australia. Western Power later reported that 80% of the power failures were linked to trees and branches falling on power lines.

Since then, approximately 55 per cent of houses in the Perth metropolitan

area now have underground power, but about 370,000 homes in Perth and 90,000 homes in regional urban areas are still connected to an overhead distribution system.

Awarded through competitive rounds, eighty-five projects have been completed under the Program, providing underground distribution connections to over 86,000 properties.

TECHNICAL SITUATION:

In Round 6, APD Engineering have been engaged by Western Power to provide expert distribution and street lighting design services for the retrospective undergrounding of 5 locations in the Perth metropolitan area – Collier, Manning, East & West Victoria Park and Menora.

Optimisation of HV/LV networks to ensure the most efficient design solution is implemented;

Street lighting design using AGi32 software to meet AS/NZS1158 requirements;

Selection and verification of new ground mounted equipment sites by GPR and potholing methods to meet AS5488-2013 requirements;

Network capacity and voltage drop calculations;

Undertake soil resistivity measurements and establish soil model; Undertake detailed Level 2 EPR assessments.

JUNCTION SUBSTATION

CLIENT: BHPLOCATION: Newman, WA

TECHNICAL SITUATION:

YANDI and Junction substations are critical Non-Process Infrastructure (NPI) HV assets that provide power to BHP’s Yandi and Mine Area C (MAC) operations. These substations were constructed in the late 90s with an Areva e-Terra proprietary SCADA system.

This SCADA system is standalone and does not form part of the BHPBIO

standard NPI HV SCADA system currently in operation. It was identified that the operations can be better improved by integrating into the clients standard.

APD Engineering provided scope definition phase services in order to enhance the existing protection system, improve the operational flexibility, remote control and monitoring of 2 substations and reduce the risk of critical failures. Similar strategies were implemented to improve the Transformer Management System (TMS) and Automatic Voltage Regulator (AVR) installed within both substations.

SHIFTS to renewable energy are becoming a growing trend in the mining industry. The exponential rise of renewable energy globally has meant a

strong demand on miners for the rare earth metals required for the associated hardware. Inversely, the rising costs of traditional forms of energy and price uncertainty of fossil fuels has put financial pressure on mining companies to reduce energy consumption costs.

Currently, it is estimated that energy costs (primarily grid, coal, natural gas & diesel) account for around 30% of a miner’s balance sheet [1], with this only expected to rise. In 2017 alone, mining energy use increased by 14% [2]. Grid power prices in Australia have doubled in the last 5 years, whereas, the cost of solar has dropped 90%, wind 50%, and battery storage is following a similar pattern [1] [3].

These price trajectories are just one factor entering the cost benefit analysis when deciding how to power a mine. Another consideration is the price volatility of fossil fuels. As an example, the price of diesel over the last 10 years varied the energy cost component of metals mining from $5.54/tonne to $17.03/tonne [2].

Then there is the cost of building and maintaining power infrastructure to connect to the grid like substations, poles, wires and access roads, often over large distances. After which, the

security and reliability of the grid to supply power to remote locations also comes into play. Bush fires are a prime example of the vulnerability of this infrastructure.

Finally, there is pressure on miners from stakeholders, clients, lobby groups and governments to reduce their carbon footprint. The mining sector accounts for roughly 10% of Australia’s total energy use and 10% of the countries CO2 emissions. Mining energy is mainly supplied by diesel (41%), natural gas (33%), and grid electricity (21%). Energy is primarily consumed as electricity for operations and as diesel for vehicles and machinery [3].

New and existing mines are looking to renewables to subsidize their energy costs and guarantee supply. Hybrid energy solutions are already happening across Australia and globally (See Table 1). It is unlikely that mines will be

run on 100% renewable energy in the short term – replacing diesel powered vehicles being a more difficult hurdle, but for powering process machinery and other infrastructure renewable energy and battery storage have become a viable alternative.

APD Engineering is well placed to facilitate these changes for our mining clients. We offer all the key services required to deliver infrastructure of this nature. Specifically, our experience with transmission and power generation infrastructure across planning, design, execution and commissioning services is invaluable to our clients. (See case study for Power stations – remote communities here).

Our understanding of the needs and drivers of mining clients also assists in

the delivery of infrastructure that is fit for purpose. As an example, safety and outage considerations play a critical role in the planning and execution of mining projects and these are areas that APD is intimately familiar, having previously delivered projects with these considerations. (See Jimblebar HV Commissioning case study here)
