Managing our impact

Oil management

Insulating oil is an essential component in the electricity system and is primarily used in transformers. Altogether, we have millions of litres of oil contained in about 30,000 oil-filled assets.Over time, oil degrades and must be replaced to remain effective. We have oil facilities in the north and south of Tasmania where about 200,000 litres of oil is processed, after which it is recycled, disposed or used as fuel for other industries every year. This process is a significant saving in environmental and economic terms.

Accidental oil spills from transformers are dealt with quickly and professionally. We have specially equipped oil spill trailers located around Tasmania to facilitate the containment and clean-up process and field crews are trained in their deployment.

Electric and magnetic fields

We recognise our community’s concern around the potential health impacts of electric and magnetic fields (EMFs).  EMFs occur naturally in the environment but extremely low frequency EMFs (ELF-EMFs) result from the production and distribution of electricity. We’re all constantly exposed to varying levels of EMFs and they cannot be felt.

The strength of EMFs is highest close to the source, with the level dropping off rapidly with distance. The ELF-EMFs associated with the electricity network have a much lower frequency and energy level than microwaves or X-rays, and do not produce the same effects on the human body.

The question of whether there is a link between ELF-EMFs and disease remains unresolved despite more than 40 years of scientific research. There’s no conclusive evidence ELF-EMFs cause biological changes related to the development of cancer.

Until more information is available, we’ll continue to take a prudent avoidance approach to the design, location and operation of the electricity network to ensure ELF-EMF levels comply with the recommendations of the Australian Radiation Protection and Nuclear Safety Agency and the EMF limits of exposure recommended by the International Commission on Non-Ionizing Radiation Protection. Energy Networks Australia is working on behalf of the industry to monitor scientific developments and industry response.

Climate change

One of the biggest challenges facing electricity networks worldwide is managing the impacts of climate change on assets to ensure safe and reliable service to customers.

To ensure climate impacts are adequately accounted for in our decision-making, we’ve identified the following impacts with potential to affect our electricity network.

Impact

Asset type

 

Transmission

Distribution

Maximum wind gust

Direct damage
Damage from vegetation

Direct damage
Damage from vegetation

Maximum temperature

Reduced capacity

Reduced capacity
Increased number of asset overloading failures

Storm intensity

Increased outages per event

 

Precipitation

 

Flooding of assets

Bushfire weather conditions

 

Increased potential for asset damage from bushfires

For each of the impacts we’ve assessed the risks and determined ways to mitigate the risks. The strategies include:

  • Trialling non-burnable power poles at selected high-value pole locations
  • Trialling fire-resistant paint for selected power poles in high fire danger locations
  • Updating our overhead distribution powerline design and construction manual
  • Monitoring for any increase in weather extremes
  • Monitoring for any increase in occurrence of asset overloading failure rates
