This is a complete fantasy as the depreciation rate on the hardware is higher than the prices of electricity.
Again, look at bitcoin mining, the miners will happily pay any carbon tax to work 24/7, it's better to run the farm to cover electricity prices and then make some pennies then to keep it off and incur depreciation costs.
Just do them when renewable supply is high and demand is low; that energy can't be stored and would have been wasted anyway.
