SOUTH AUSTRALIA'S POWER WOES:

Severe thunderstorms bring down four major transmission lines and 21 towers in SA's north leading to a statewide blackout when the state is separated from the national network.

* DEC 27, 2016

Thunderstorms across the Adelaide Hills bring down power lines and cause widespread blackouts with 155,000 properties losing power.

* JAN 19, 2017

Another series of storms cause power outages across Adelaide. This time 58,000 homes are blacked out.

* FEB 8, 2017

Heatwave conditions prompt the Australian Energy Market Operator to order load shedding in SA to reduce record demand on the electricity network. A software problem with SA Power Networks results in 90,000 properties being blacked out for about 30 minutes, three times the number ordered by AEMO.

An explosion and fire at Adelaide Torrens Island Power Station raise fears of more blackouts. Power cuts are narrowly avoided by using generating capacity in Victoria.
