Las night I saw a news story on Nine News about the 2 billion dollar tri state interconnector, along with this article from the ABC.

https://www.abc.net.au/news/2022-08-04/powering-sa-nsw-interconnector-project-energy-connect/101296228

Currently an excess power from SA is transmitted via the Vic/SA INTERCONNECTOR, Tasmania has the Bass Straight interconnector with Victoria. Victoria has an interconnector with NSW, and QLD has an interconnector with NSW.

The ABC story is a bit of a lie, because both Tasmania and South Australia almost every day rely on powerfrom the interconnectors because of their daily shortfall, NSW relies heavily on Qld and Vic 95% of every day for power to make up for their shortfall, Vic and Qld occasionally require support from the interconnectors.

At this very moment Tasmania has a 200mw shortfall South Australia a 110mw excess, NSW is about 400mw short, Victoria has 640mw excess and Qld has a 110mw excess.

Wait till 9 o'clock tonight when the solar is zero and the wind has abated then the majority of power generation comes from Coal, Gas and Hydro.

Its an inconvenient fact that the renewable circus denies.

 Nothing unusual there Graham. ABC is full of lies, which suits the gullible, and those among us who can't think logically. Cheers

In Aus it is a no brainer.

Leave the current methods in place until we or the world come up with something reliable.

Or dare anyone mention the elephant in the room.

We could have a facility in northern SA or NT that would power all of Australia 24-7 and most of SE Asia as well.

Just a thing for you to consider, do you know that those massive solar farms are generate less power than all those small solar arrays.

Rather than build large solar farms on good agriculture land, it is more effective if every house in Australia had solar panels installed because it would provide for a greater footprint to capture the sun range for a longer time.

 Good and accurate facts from you once again Gundog.

If your above comment was directed toward my previous statement, *my elephant in the room* had nothing to do with Solar or wind.

At approximately  2100 lat night the VRE WAS 7% and Renewables was 14%, this morning we are at 14 and 22 percent.

% VRE (i.e. Variable Renewable Energy)

Whilst the ratios might seem similar in purpose, for us the % VRE (Variable Renewable Energy) is much more important, as it speaks to some of the underlying challenges that will need to be worked through in the energy transition because wind and solar:

1. 1. Is intermittent
   2. Is not synchronous
   3. Is not dispatchable (i.e. Wind and Large Solar is registered as Semi-Scheduled in the NEM, and rooftop PV is even less controllable and indeed is invisible in real time)

% Renewable

The % Renewable metric adds in the contribution from hydro in the NEM but hydro is quite different than Wind and Solar because:

1. 1. its not intermittent,
   2. its synchronous,
   3. its fully dispatchable (e.g. registered as fully Scheduled)
