The AEMO South Australian Electricity Report for November 2017 :-
http://www.aemo.com.au/-/media/Files...eport-2017.pdf
This is advisory information provided to the South Australian Minister
for Mineral Resources and Energy about South Australia’s electricity
supply and demand.
AEMO projects that in the 10 year outlook, 2017-2018 will be the highest
risk period for South Australia for a unserved energy event but that "the risk
is being addressed by the South Australian Government’s Energy Plan
developing additional diesel generation and battery storage, and AEMO
pursuing supply and demand response".
They note, "the risks are forecast (subject to significant uncertainty) to
reduce after 2017–18. From 2018–19, the forecast maximum demand is
expected to be moderated by increasing PV uptake and energy efficiency,
and additional large-scale renewable generation is expected to be developed."
The report notes that 30% of dwellings in South Australia now have
rooftop PV systems installed which contribute 9.2% of the South Australian
power generation mix.
The report also notes that AEMO has acted with industry and government to
implement their own previous recommendations following the September
2016 black system event.
Specifically, to minimize the chance of South Australia becoming islanded
from the national grid, like when the interconnector was disrupted during the
storm, and to increase the likelihood, in the event of islanding, that a
stable electrical island in South Australia can be sustained.

In a post the other day I mentioned a transmission line technology called
HVDC - High Voltage Direct Current :-

There are a small number of HVDC links in Australia already, including the
Murraylink light bipolar interconnector which connects the Riverland
region on South Australia to the Sunraysia region in Victoria. It may
well be the world's longest underground power transmission system. It
allows for electricity to be traded in either direction.
Basslink is a 290km long HVDC submarine cable that connects Victoria
and Tasmania and again allows energy to be traded in either direction.
The Terranora interconnector is a 65km long underground light HVDC link
that allows NSW and Qld to trade power in either direction.
