Temporary towers to restore SA power

Power transmission company ElectraNet will bring in temporary towers from interstate to repair transmission lines damaged in South Australia's mid-north.

More than 20 towers were brought down by strong winds on Wednesday, causing the entire transmission network to shut down, plunging the state into darkness.

ElectraNet executive manager of network service Simon Emms says the company hopes to have one of the three backbone circuits restored by Sunday and will build on that as fast as possible.

Mr Emms said the company continued to work on restoring power to those areas of the state still without electricity but establishing a timeline was difficult.

"That's a very fair question but very hard to answer at the moment," he said.

"Obviously, the current wind conditions are hampering restoration efforts. Access to the sites is very difficult and we haven't finished fully patrolling all the lines yet to ensure we can safely energise them.

"When we've finished the patrols, then we'll safely energise. We'll then restore the assets with emergency towers."

Mr Emms said he was not aware of any power system in the world that could handle losing as much energy so quickly without going into blackout.

He said such events were not common but were not unheard of.
