I'm not entirely sure how much power reserves does Kazakhstan have, but if they are not experiencing power outages across the country, then they would be able to accommodate more miners, tax them, and be a haven for miners that were displaced from other countries or that are already having a hard time getting profits due to expensive taxation and electricity costs.
By capacity, they claim they have
an available capacity is 20078,6 MW.
If we assume 100%, which is impossible and never achieved anywhere in the world, that would translate in 175 TWh with an annual consumption of 107TWh.
If we assume the average 80% it will just fit the normal consumption.
They have a slight export of 0.9 TWh, but that balance is pretty fragile.
So it will all come to a math problem, is more efficient to sell that coal or to burn it to produce energy and sell that energy to miners?
And the other being that Kazasthan has seen an energy consumption increase of 2.0%, and we're talking of a country that still tries to accelerate its economy so that will only grow.
Probably they could accommodate 20-30% of the former global hashrate but anywhere above that and the numbers start giving errors.
I am not familiar with US taxes, but so far mining in Kazakhstan is much more profitable.
Why?
From your article:
The cost of electricity varies. Depends on the region, in the north it is cheaper, the west and east are more expensive, the highest tariffs are in the south. But on average it is 4-5 cents per kW. Major players most likely found options for 3 cents.
vs
Marathon will pay $0.028/kWh for the energy, which is about a quarter of the average US domestic rate of around $0.11/kWh.
The cost is the same for power, I seriously doubt you have even a single deduction in Kazahstan (might be wrong), while in the US:
Jan 6, 2021 – The Section 179 deduction for 2021 is $1,050,000 (up from $1,040,000 in 2020). This means U.S. companies can deduct the full price of qualified equipment purchases, up to $1,050,000, with a “total equipment purchase” limit of $2.62 million (up from $2.59 million in 2020). The deduction includes both new and used qualified equipment.
In addition, businesses can take advantage of 100% bonus depreciation on both new and used equipment for the entirety of 2021.
