Asset Efficiency Improvements

TransGrid is undergoing a range of projects across our existing transmission network in NSW that will improve the efficiency of their operations and delivery of electricity to consumers.

The Projects include:

  • Dynamic Line Rating Project
  • Low Spans Transmission Line Project
  • Optical Fibre Ground Wire Project.

  • Dynamic Line Rating Project

    ​The dynamic line rating  project involves the installation of weather stations at strategically located positions along some of our existing transmission lines and substations. The weather stations will measure ambient temperature, wind speed and direction and solar radiation. The weather stations will provide real time data to allow for the more efficient operation of existing transmission lines under localised weather conditions. By utilising real time weather information TransGrid will be able to maximise the operation and electricity transfer capacity of our existing transmission lines.

  • Low Spans Transmission Line Project

    ​The low spans transmission line project involves raising the height of some spans of existing transmission lines that have been identified as having low clearance to ground or objects. This project will enable TransGrid to fully utilise the electricity transfer capacity of these existing transmission lines.

  • Optical Fibre Ground Wire Project

    ​The optical fibre ground wire project involves the replacement of ageing ground wires located on the top of existing transmission lines with new optic fibre cables. The optic fibre cables will continue to provide the coverage of the old ground wires but also provide increased communication capabilities to improve the efficient and safe operation of our transmission network.
