The current price of electricity in South Australia is negative $850 per megawatt hour.
This means for every kilowatt hour of electricity you consume, the power companies will pay you 85 cents at the spot price because they are so desperate to unload electricity from the grid.
Coal and nuclear power plants will never survive in these new market conditions because they cannot ramp up and down. Coal plants take days to ramp down, and as we learned from the Chernobyl series, nuclear plants get xenon poisoning and other bad things if they are run too low.
Funny story...
Back in 2015 I put my S4 antminer on ebay because the cost of electricity was more than the bitcoin I was mining.
Some dude in Australia bought it and my paypal account was credited.
Only problem was I had to pay shipping, as me being new to ebay selling, I did not realize you have to specify in the ad
shipping not included.Turns out after paying for shipping to Australia ,not only did that eat my selling price,
I had to shell out another $50. IOW, I'm paying some dude in Australia $50 to take my s4 bitcoin miner... Um...are you shitting me?
So of course I refunded him the money thru paypal and emailed him, apologizing that I was cancelling the sale.
He got totally irate and claimed I was a scammer, when in reality I was just an ebay noob, ignorant of the fact of knowing not to sell a miner without specifying
shipping not included.
I googled and found out that if you are selling a miner, make sure you specify
shipping not included otherwise australian buyers will jump on your ignorance and
call you a scammer in feedback when you cancel sale! Needless to say, I dont sell on ebay any more.
