Many networks face intense scrutiny and their risk committees are regularly reviewing options available to reduce the risk and even prevent destruction from wildfires. The increased occurrence and severity globally of out of controls fires over recent years has gained attention from territorial and national authorities as well as product developers and manufacturers.

Developed in response to the damage caused by a growing incidence of wild fires in the likes of California and Australia, many of these products are available to networks and contractors in many countries.

Covid-19 restrictions may have led to the cancellation of Annual Connection, the electricity supply industry’s annual celebration of its skills, training and workers, but organisers continue to shine a light on the sector’s talent and opportunities.

Annual Connection was scheduled for Christchurch in November. The three-day event, a joint initiative between Connexis, the infrastructure industry training body, and industry, is the highlight of the electricity supply calendar.

Connexis Director Kaarin Gaukrodger says it was a difficult decision to cancel this year’s event. “While the cancellation is a major disappointment for all involved, to hold Annual Connection in its planned format in the current Covid climate is just not possible.”

It is a wrap for Girls with Hi-Vis® 2021 but the legacy of this year’s campaign, the most successful in its 10-year history, could bring more diversity to the energy industry and be part of the solution to persistent skills gaps in the workforce.

GWHV is an initiative founded and run by Connexis, the infrastructure Industry Training Organisation. It gives female high school students the opportunity to visit an infrastructure company, get hands-on experience, and hear from inspirational women in the industry.

As the world gets warmer and the tech gets cooler, what role will energy play in our sustainable future? LUMO is bringing together a range of speakers to explore this question through the intersection of energy, humanity and technology. It provides a platform to challenge the status quo and shift the national narrative of energy “so that it becomes a sector that all New Zealanders want to be a part of,” says organiser Dee Anderson.

LUMO is being hosted by Energy Academy, which was born out of electricity distribution company Orion Group’s commitment to “powering a cleaner and brighter future”.

The story of New Zealand’s energy industry is incomplete without considering the reach it has globally, particularly in the geothermal sector. New Zealand has had a significant impact in developing the global geothermal industry. The direct reduction of carbon emissions by international geothermal projects we have enabled is equal in magnitude to all of New Zealand’s net carbon dioxide emissions (about 12 MT/year). East Africa is one of the key regions that our industry has been supporting for 50 years and a good example of how our export technology has been applied. So how and why is it that we became so involved in a region half a world away?

Voltage regulators are overhead assets that most networks neither have a lot of, nor are they replaced very often. When a network needs a new or replacement regulator, sourcing can be a bit of a head scratcher – especially in these Covid times with some manufacturers advising lead-times of 12 months or more.

USA based Howard Industries SVR-1 single-phase step voltage regulators are tap changing autotransformers designed to automatically regulate distribution line voltages in a range of +/-10 per cent in 32 steps. One of the most popular and reliable voltage regulators in the USA, they have been getting a lot of attention recently in New Zealand and Australia. Quality and reliability are the attributes most talked about – expressed as lower failure rates and consequently lower maintenance and operating costs. For example the option of a painted stainless tank increases the life of the unit significantly over a mild steel unit, especially in coastal locations.

The 2021 landscape for the infrastructure industry is a mix of unique opportunities and challenges. While our workforce continues to be resilient and adaptable to change, Covid-19 has reshaped the lives of not only our workforce but the entire population of New Zealand.

With challenge comes opportunity and because of the critical nature of the work our industry does, ensuring the effective day to day running of the country, the demand for skilled people continues. The labour market has constricted from the impact of Covid-19 but restrictions on people movement around the world has driven demand in the energy sector that has for years been reliant on immigration to cover local skills shortages.

Benefit from enhanced corrosion protection for line hardware and substation components with TDG, which offers superior steel protection, is less harmful to the environment, and costs less than stainless steel.

Do you have corrosion problems in line and substation hardware that is prematurely limiting the life of your electrical equipment?

Metal corrosion on galvanised parts and equipment – particularly in coastal areas – is a significant problem on network assets. The lifespan of Hot Dipped Galvanised parts is typical 5-15 years, which is generally significantly less than the mechanical life expectancy of the parts or equipment.

Early in 2021 distributors and traders will be able to do business under the new Default Distributor Agreement. The DDA brings about a number of changes. One of the changes is improved clarity in the provision of consumption data to distributors by traders (Section 12A., Appendix C). This has and continues to be a contentious issue between industry players. On the one hand the information is vital to the improvement of management of the LV network and on the other hand there is perceived risk of the information being used in ways that it wasn’t intended and potentially damaging for traders or consumers.

Without a robust power supply, essential facilities might not operate following a significant seismic event. With around 20,000 earthquakes in New Zealand each year (GNS Science, 2018), and the likelihood of a significant seismic event occurring in the future, the seismic strengthening of Wellington Electricity’s substation buildings is paramount to ensuring essential facilities can continue to operate during and after such an event. Jacobs provided detailed seismic assessments and seismic retrofit designs for more than 60 existing critical substation buildings.

The Government’s recently announced Free Trades Training scheme is a welcome boost for the infrastructure industry. It provides a platform for attracting keen new workers to build the required workforce capacity and capability to deliver on the pipeline of infrastructure projects.

The Targeted Training and Apprenticeship Fund (TTAF – also called Free Trades Training) of $320 million was announced by the Government to encourage vocational education opportunities for everyone.

Connexis is the industry training organisation for infrastructure, and chief executive Toby Beaglehole says, “Free Trades Training means that a wide range of Connexis apprenticeships and training are now available free, to both existing employees as well as new ones coming on board.

Has your network considered the covered MV Conductor to improve SAIDI?

An open invitation to a webinar – Covered Conductor for MV Overhead Lines – postponed to 30 September 2020.

Overview

MV overhead networks are predominantly uninsulated conductors. However, using a covered conductor in specific locations can significantly improve your network SAIDI as well as offering other advantages. The covered conductor system is designed to provide protection from flashovers from conductors clashing, bird or animal incursions, or tree branches falling onto the line, especially in severe weather conditions and when there is high pollution.
