The future of energy generation and storage

No but my understanding is making nuclear arms grade for weapons a spin off is fuel grade that can be used in reactors.

If something is going to operate from (for example) 2035 to 2085 then it's entirely reasonable to spread the cost over that period. That's exactly what would be done with any form of generation, the cost is spread over its total life (or more precisely, it's spread over its total generated output).

Now I do agree there are problems and omissions, but if something lasts 5, 10, 50 or 100 years then of itself it's a normal thing to spread the cost over that time.

In saying that I'm inherently wary of arguments for using short lifespans simply because they bias toward gas and diesel. You'll never get a long lived asset such as hydro to stack up if someone decides it's to be written off financially after 20 years, but it's very different if it's run for a century or more.

Extremely high demand in SA today with the temperature officially reaching 43.3 degrees in the Adelaide CBD with some suburbs recording up to 44.7 degrees.

Outside the metropolitan area parts of the state on the grid recorded up to 46.0 degrees, with some off-grid small towns recording up to 48.7 degrees.

Those are all proper BOM measurements.

Unsurprisingly that resulted in high electricity demand.

Including the estimated output of behind the meter generation, that is primarily rooftop solar, demand reached 3730MW at 17:30 whilst looking only at large scale centralised generation (including wind, solar, batteries, gas, etc) demand peaked at 3358MW at 19:45

The second figure is just short of the all time record high whilst the first, including rooftop solar in the data, is an all time high.

For the chart below:
Yellow = Solar
Green = Wind
Blue = Battery
Orange = Gas
Red = Diesel
Purple = from Victoria

Spreading the cost is not something you do when you favor solar farms or batteries to be fully write off after 15y max, so the biased opinion like the pages above , but it is ok: we will ship crushed panels to India,as we do now, except we will probably the one filling our desert with craps in 15y seeing our current economic trajectory.
