Another Test For South Australia's Power Grid

It could happen again.

A warning about possible load shedding's been issued for today as planned maintenance work is carried out on a high-voltage transmission line in Victoria.

The work's being done on the link that feeds one of the circuits to the Heywood Interconnector.

That's the one which supplies most of the power Victoria sends to South Australia.

We're told the maintenance was meant to happen at the weekend but had to be postponed because of a fire at the Torrens Island Power Station on Friday.

The Australian Energy Market Operator says the state's energy grid should hold up during the works and there's enough in reserve to meet demand.

But should demand spike unexpectedly interstate - or a fire breakout somewhere else in the network - then load shedding could occur.
