Enabling works for Molonglo 3 East

132kV power lines close to Coppins Crossing, Molonglo Valley, 28 March 2021

Nobody likes power lines – really nobody – but everybody likes the convenience that electricity provides. The power line across Molonglo 3 East will be buried along William Hovell Drive in preparation of the estate’s construction.

The tender for the Molonglo 132KV Transmission Line Relocation Project has finally been released. This was expected.

The Molonglo 132kV Transmission Line Relocation Project involves the installation of 6-way and 12-way electrical conduits across a 9 km alignment. The project site is located between William Hovell Drive and the Tuggeranong Parkway, an area of land north of the Molonglo River and west of the National Arboretum Canberra

Power lines are a little like the Goldilocks story, there is too big, too small and just right. The big ones are 330 kV and above, the little ones are 11 kV and below, found in the suburbs, and the middle size ones are 132 kV, such as those along the length of the Molonglo Valley on the northern side.

To make way for the construction, above ground obstructions in Molonglo 3 East will be removed. Early this year, the tender was released to the 11 kV power lines and now for the 132 kV lines. Power lines are laid underground in the Molonglo Valley.

“This porridge is too hot!” she exclaimed.

So, she tasted the porridge from the second bowl.

“This porridge is too cold,” she said.

So, she tasted the last bowl of porridge.

“Ahhh, this porridge is just right,” she said happily and she ate it all up.

The route

The planned route for the 9 km of cables is around the north of Whitlam, along William Hovell Drive and then south past the edge of the National Arboretum, and under the Tuggeranong Parkway to join with the power lines to Woden.

The Bindubi Street extension will cross the cables. It follows, that the northeast section of Molonglo 3 East will require an easement through the middle of the suburb. It could look a lot like an elongated park and is well suited for a cycling path, assuming the suburb is relative flat.
