If they're eventually taking 100% renewables over the course of a normal trading period, I can live with that. They're achieving their objectives of getting cheaper power, reducing their emissions and helping drive down the cost of renewables (and fossil fuel power out of the system).

I think you've got a complete misunderstanding of how off take works and what it is there for and what it is dressed up to be
Off take provides the banks and lenders the confidence that an investment in infrastructure has market support. So it is a tool to secure investment.
The terms of off take vary dramatically and can increase or decrease the operational risk of a business. but think of it like insurance..........it costs the business $s.
Then as there is no ability to store the PPA, this is about selling the carbon credits when they have to buy the energy from the market.
So who pays for this dirty industries dirty games? Ordinary people!
Further the major input in aluminium refining is heat not electricity. So it would be interesting to understand how renewable will deliver heat.
Then we have the deception:
Background -Tomago Refinery has shut down a number of times due to spikes in price due to unreliable renewables and the shut down of Liddell
As a result they are supporting a 660MW gas power plant. Thus the see through on the deception is clear to see.

The cheapest wind in Australia firmed is $0.22 where the cheapest coal was $0.04 before the cost of reliable supply was pushed onto the P/L of reliable producers. So I'm not sure how the cheaper power price claim holds true.
Further they are using gas for heat and power, so the CO2 is still there but others are picking up the carbon price. Very clever deception!

a bit of a reality check about what the smelter really thinks:
The country’s biggest energy user says the federal government’s $600 million gas-fired power plant in NSW’s Hunter Valley is “absolutely” needed to keep the lights on in the state, even as experts maintain it is not required to either keep supply reliable or power prices affordable.

The smelter’s power supply contract with AGL allows the retailer to ask Tomago to cut output when wholesale prices spike towards the maximum $15,000 a megawatt hour.
He noted that at 5am on Wednesday morning, 96 per cent of NSW’s electricity supply was being provided by black coal plants.
“It’s not going to be solar that fills that void and it’s not going to be wind when there is no wind,” Mr Howell said.
“We think it is a very prudent and responsible measure to go ahead with this power station because the reality is, the reason the lights and heaters stayed on last night is because Tomago came off.”

This is because the majority of NSW's power is normally black coal generated. You could basically pick any time on any day in NSW and the vast majority of their power would be black coal produced. Interesting to compare vs South Australia on the same day...

I mean, for interests sake you could also compare it to South Australia's energy generation at 5am today.

Dirty Germany and dirty South Australia should look at adopting solutions that deliver 14-70g CO2 per Kwhr
Perhaps when we get serious like others did in the 1980s or before, we can finally celebrate

this is a little bit of a furphy though as only 18% of our energy consumption is electricity and the majority of the 82% is much dirtier as its off grid
Rare metals needed to fuel our high-tech future are in our hands right now
Transitioning the world to clean energy is going to require a huge amount of different types of metals. But do we have enough, where will we get them from, and what impact will that have on the environment?
Aus pulling more than its weight here.
Do we get a credit on the climate change scoreboard that takes to account our coal burnt overseas?
Sun tax to be “optional” under new solar export plan, but limits may still apply
New rules mean solar homes will need to pay to access the best feed-in-tariffs and avoid curtailment.
reneweconomy.com.au
'On Thursday, the AEMC delivered its long-awaited final determination on a controversial plan to charge households and businesses for the ability to sell their excess solar power into the grid.
Advocates have argued that the export charges are necessary to help fund much-needed upgrades to electricity networks. Electricity companies had complained that they had been unable to keep up with the surging uptake of rooftop solar – resulting in many households having their output curtailed.
The AEMC says that under the final rules, network companies would be required to invest in making the grid “solar and battery friendly”, ensuring that households and businesses wanting to install their own energy systems will not be prevented from connecting and exporting to the grid.'
'The exact structure of the fees won’t be known for several years while different networks put the packages together and seek approval from regulators.'
Q for the ordinary consumer, is this another excuse to make us pay more?

Probably though it shouldn't be. The companies could cover this but you know, they'd rather you cover any losses so their profits look good.
Why the companies why not those chosing to export to the grid? Effectively its the consumer who will pay.
The consumer always pays. Same as when air conditioners went mainstream in the early 2000s and the companies needed to invest in the grid to deal with peak demand. Nobody was saying we should have an air conditioner tax. The costs were shared.

I think you're missing the point. this is not about the grid, it's about excess supply.
when supply exceeds demand, suppliers are charged a fee to discourage supply
if that is the case, why shouldn't all be treated equal?
.....coal prices are trading at record highs.
Thermal coal on Wednesday made even further gains, up 1.4 per cent to $US166.40 a tonne while coking coal futures are up 0.5 per cent to $US219.50.

Awesome way to encourage battery takeup.
ill be on a battery the day before this starts.
we generate sooooo much more power than we use its not even funny.

Over a full year what % of the energy does SA import, and at peak times (I assume early evenings in summer) how much are they importing?
We all know its after dark thats the problem & that is after we enhance the grid.
Dispatchable power.

According to https://opennem.org.au/energy/sa1/?range=1y&interval=1w over the last year SA has imported 9% of their power.
Over summer it shows about 13% imported. Individual days are showing up to 28% as far as I can see but it isn't broken down to peak times of the day going back that far.

Thanks ! Im assuming the bulk of that imported power would be non renewable ?

No we dont.
my twin freezers are set to -24°c
they are automatically switched off at 7pm
My spa turns itself off at 2030h
in the laundry we have a dishwasher, a clothes washer and a dryer - we have two plugs for those devices so only two can be used at a time and they are only used during the day. we pack them at night and turn them on as we leave for work.
If its shitty weather we dont use the dryer.
This leaves the fridge and heating / cooling
we have insulated the house and cooking dinner is usually enough to heat the house - if not a blip on the reverse cycle gets it warm enough for the evening.
in summer we blast the aircon in the day as cold as it goes then switch it to dehumidify at night and run a fan.
our bills are rarely much more than the service fee.
a ten kw battery added to the fact that we can change the solar inverters to output 7 kw and add more panels is more than enough for us to easily go off grid.
A small < 1kw wind generator would make that pretty much foolproof.
if you wanna blast everythingin the house this might not work but with minor changes to your routine we always produce more electricity than we use - even in this winter which has been the most overcast and rainy winter weve had in 50 years.
