The clean energy industry is on the verge of a major breakthrough, with 16 renewable projects being completed in 2017, adding 700 MW of new generation. Seven times that amount are currently under construction or have secured financial support. This equates to approximately an $11 billion investment and the creation of almost 6000 new jobs.
The Clean Energy Council (CEC) has recently released their 2018 report, which shows Australia has enough projects running at a sufficiently advanced stage to meet the 2020 Renewable Energy Target (RET). However, the percentage of renewable energy fell from 17.3 per cent in 2016 to 17 per cent in 2017. The CEC attribute this to a decline in hydro generation caused by reduced rainfall in catchment areas.
Despite this, it was still a record year for the renewable energy sector, according to CEC chief executive Kane Thornton. Large-scale wind and solar project activity has increased investment by 150 per cent in Australia. Four large-scale solar projects were completed in 2017, with the total capacity of installed solar reaching 450 MW. This is remarkable considering only 34 MW were installed at the end of 2014.
In the small-scale market, almost 1.1 GW of solar PV was installed — a record for the rooftop solar industry. Twelve per cent of the 172,000 solar systems installed in 2017 included a battery, which is a 7 per cent increase from 2016. Over 40 per cent of national storage installations occurred in New South Wales. In the medium-scale sector, 131 projects added 53 MW of new capacity. This means there’s now 167 MW of cumulative capacity, demonstrating an increase of over 500 per cent in the past five years.
Did you know that coal dust can lead to mine explosions? Dust is present in numerous industries with flour, sawdust and sugar potentially as explosive as coal dust. Vapours, mists and gases are also factors that may trigger explosions when exposed to spark ignition.
Oil and gas installations, petrochemical, chemical plants, grain storage, coal handling and refuelling areas often create hazardous areas resulting from flammable gases, vapours, mists and dusts which can produce explosive mixtures with air. The electrical, mechanical and instrumentation equipment installed in these potentially hazardous areas must be designed to provide protection against the possibility of gas or dust ignition. Solutions to these problems can be certified flameproof and intrinsically safe equipment.
Dusts are solid airborne particles, often created by operations such as grinding, crushing, milling and sanding. The size of the dust particles is important as there is a difference between inhalable and respirable dusts and the nature of the hazards they present.
Gases are formless fluids usually produced by chemical processes involving combustion or by the interaction of chemical substance. A gas will normally seek to fill the space completely into which it is liberated, for example, nitrogen gas widely used in vessels due to its chemically inert properties.
Wiring Rules Revision
Techncial paper presented at the IDC Technologies 2nd Electrical Regulatory Compliance Conference in Perth on November 29th & 30th 2017.
By Gary Busbridge - Standardisation Manager, Clipsal and Schneider Electric Partner Business
The Wiring Rules affect your businesses every day. Whether you are an electrical contractor or an electrical engineer, the changes to each clause in a revision of the Wiring Rules affect your compliance with State legislation.
The new and revised Wiring Rules should be ready for publishing by May/June 2018. Is your business prepared for these amendments?
This workshop is intended to provide an opportunity to work through those amendments clause-by-clause and discuss the reasoning with the Chair of the Wiring Rules committee. This will also provide a unique insight into the actual intent behind the amendments.
A finalised draft was issued for Public Comment early in 2016. This is a predetermined part of the standards development process and not surprisingly it is named the Public Comment phase. Yes, that is right each one of the electrical industry stakeholders, from the biggest businesses to the one-man show, had an opportunity to review and provide comment for the Wiring Rules committee to consider.
Over 2000 comments have been received and reviewed by the committee who have resolved these as an “agreed”, “not agreed” or “noted” comment. You may not get what you wanted but you have a right to view the resultant committee decision after this resolution process. Incidentally there have been many comments that make plenty of sense but further work is need to refine them, so these we are consigning to Amendment 1.
The document is being readied for Committee Ballot. The committee may or may not accept the document for various reasons and any negative votes must be reconciled before it moves to a publishing phase.
There are over 200 changes that will be presented at the conference and there is a preponderance of technical updates that are essential for you to be aware. Let’s get started on the major changes for each section.

Have you ever considered living off the grid, in a community that co-exists with nature – growing your own vegetables, minimising waste and environmental impact, and creating your own power through solar energy? This is exactly what the 70 members of the Moora Moora community do. Located on Mount Toolebewong in Victoria, approximately 70 km from Melbourne, this community consists of 30 housing units grouped in six clusters. Everyone living here owns a share in the land, infrastructure and machinery.
Moora Moora was developed with three aims: cooperation, reducing environmental impact and education. Many of its members were concerned with the overcrowding and isolation of city life, so they decided to move into this ‘intentional community,’ which finds its purpose in the pursuit for individual and community development. The notion of an intentional community comes from the idea of living cooperatively in a village which reflects shared values.
Fifty adults and 20 children currently live in Moora Moora. Their shared philosophy is that adults and children can’t be autonomous if they’re forced to rely on each other, so different members of the community will look after the children. This also feeds into the idea that children need more than one playmate and space that’s free of urban dangers to allow them to learn and be creative.
While members often have jobs outside of the community, they’re expected to commit to internal workdays, attend meetings and social events and be actively involved in the community life. Members are encouraged to take part in industries that directly benefit the cooperative, such as farming, teaching, mechanics, building, carpentry and spinning and weaving.
Community member Glen Morris is responsible for the power supply to the Moora Moora community, given they live off the electricity grid. He has designed a micro-grid system out of 20 different brands of inverters, batteries and panels. With more than 20 years’ experience in the renewable energy sector, he’s personally lived off the grid for most of that time. Glen is the Keynote Speaker and workshop presenter at the upcoming IDC Solar-Diesel Hybrid & Battery Systems Conference in Brisbane, Queensland. He will be running a full-day workshop on “Designing Stand-Alone Power Systems,” drawing on his own experience of building and maintain an autonomous grid.

In April 2018 IDC Events had the pleasure of running the 6th Arc Flash Conference in Perth, Australia.
The objective of this conference was to provide delegates with the latest developments and best practice to deal with arc flash hazards and electric shock in Australia. Attendees had the opportunity to discuss their arc flash issues with our presenters and learn about practical applications to improve arc flash safety in their work places. The focus throughout was on the experiences of end users and technical solutions to arc flash issues, industry trends, standards developments and new techniques to tackle existing arc flash threats.
The conference featured one half day workshop on The Anatomy of Arc Flash PPE by international keynote speaker Jim Pollard of Unlimited PPE Inc who visited from Canada plus the following topics:
