You really have no conception of what a tiny chickenfeed amount that this is in the context of power generation, do you?
Let’s talk about the ever-so-topical Liddell coal power station, for comparison.
In 2014 the NSW govt privatised Liddell, after spending hundreds of millions (I haven’t been able to find a more precise number) upgrading it to make it a more attractive sale. It was sold to AGL for ~$1.55 billion as part of a package that included the newer Bayswater coal plant and concessional coal contracts. AGLs annual report that year valued the coal contracts at $768million and the Bayswater plant at $780 million (this was seen as a bargain, in terms of $ per MW). It valued the Liddell part of the transaction at a grand total of nothing.
AGL, between 2014 and now, has sunk $150 million into refurbishing and maintaining Liddell. Mind you, none of this helped it be actually useful - it’s so unreliable that only averages around 50% of its maximum generation capacity, and in hot weather (when it would be most useful) it is least dependable. The entire thing was offline during last year’s NSW heatwaves.
Estimates to refurbish the plant to keep the thing running for another mere 5 years run between $500 million and $1 billion. The work to rehabilitate the site after it closes down is costed at $898 million. Any purchaser of the plant, or the govt if they nationalise it, will have to pay those costs. And that’s on top of normal running costs, and they can’t rely on getting much back, given Liddell is so unreliable and polluting it’d really only be used as a generator of be a last-resort anyway.
It actually almost seems possible that AGL will get the plant for free from the NSW govt (who’d just finished spending hundreds of millions of taxpayers $ upgrading it), then sell it back for yet more taxpayers $ to the federal govt, who will then spend in the order of $1.3-1,8 billion more of taxpayers money on stickytape to hold the thing together for a little while, and on cleaning up the mess when it inevitably falls apart in a few years anyway.
(edit, fixed a million/billion typo!)
