The Mid North Coast Region is one of New South Wales' fastest growing areas. Forecasts indicate that population in the region is likely to continue to grow in the medium to long term.
To increase capacity of the electricity supply to Port Macquarie, TransGrid has commenced construction of a 132,000 volt line between Kempsey and Port Macquarie. The estimated cost of this project is $28 million.
The new double capacity line will replace the existing wood pole line between Kempsey and Port Macquarie and will strengthen power supply in the region. The new line is being built with concrete poles, using modern materials that will enable TransGrid to build the most compact power line possible within the same easement as the previous line.
The extensive work undertaken in developing the final project solution pays particular attention to the environment and the community. This was evident when TransGrid undertook the more complex task of rebuilding the existing line rather than establishing a new line route. The decision resulted in the project receiving acceptance and support by existing landowners and the community.
The project draws upon TransGrid's extensive project management expertise, with the project team having to tackle problems arising from wet weather and floods. This has required TransGrid to investigate various techniques such as special tracked vehicles with the ability to work on wet ground with minimal environmental impact.
TransGrid is utilising a specially-developed construction method called "close approach". This means new electricity poles can be constructed alongside existing power lines, without the need to disconnect them first. In the past, this required the lines to be switched off, but by using these special procedures the work can be undertaken while at the same time not compromising safety. The benefits from using this approach will be keeping a reliable supply to the area, as well as reducing delays due to wet weather.
Construction of the line commenced in late 2008 with total project completion expected by late 2010.
