This is an opinion editorial by Jaran Mellerud an analyst at Arcane research focusing on Bitcoin mining.
Most people disregard bitcoin miners as simply yet another energy-intensive industry, but there is one big difference: Bitcoin miners are uniquely flexible concerning when and where they consume energy. Arcane Research’s new report titled “How Bitcoin Mining Can Transform the Energy Industry” found five factors making bitcoin miners unique energy consumers, which I will explain here.
Bitcoin Miners Are Price-Responsive Energy Consumers
A price-responsive energy consumer is financially incentivized to adjust its energy consumption based on the energy price. Bitcoin miners refine energy into bitcoin and are only financially incentivized to do this if the energy input is priced lower than the bitcoin output.
The chart below shows the break-even energy price of mining bitcoin during 2021 and parts of 2022. This break-even energy price is the dollar-denominated income per MWh of energy fed into a bitcoin mining machine (Antminer S19). Suppose a bitcoin miner’s price per MWh increases above this line. In that case, the miner is financially incentivized to turn off its machines as it would earn less by using this energy for bitcoin mining than it would pay for the energy.
Since energy is such a significant component of the cost structure, miners always pay attention to their energy prices and can calculate their break-even energy prices with certainty. During energy scarcity events, the spot energy price will rise far higher than miners’ break-even energy price, incentivizing miners to curtail production and let the energy flow to less price-responsive energy consumers, like households.
Bitcoin Mining Is An Interruptible Process
Not only are bitcoin miners financially incentivized to stop consuming energy if spot energy prices rise above their break-even energy price, but they are also fully able to do so due to the interruptible nature of the bitcoin mining process.
A bitcoin miner can interrupt its production and energy consumption at a moment’s notice without losing more money than the alternative cost of not producing bitcoin. It can not only interrupt its consumption but also granularly adjust it up or down in kilowatt increments.
The interruptibility of the bitcoin mining process becomes apparent when comparing a bitcoin mining facility to a conventional data center. A conventional data center performs many complex processes and must maintain uptime due to its customers. Uptime is so crucial for data centers that they are categorized from tier one to four based on their uptime guarantees and power redundancies. Bitcoin miners, and some other high-performance computing processes, are the only interruptible data center processes.
Since bitcoin mining is an interruptible and price-responsive load, the process is exceptionally suitable as a demand response tool that can help strengthen electricity systems.
Bitcoin Mining Operations Are Location-Agnostic
Most energy-intensive industries produce physical products that require access to supply chains. On the other hand, Bitcoin miners produce hashes sold through the internet. Therefore, a bitcoin mining facility can generally be built in any location with cheap energy and internet access.
The location agnosticism of bitcoin mining makes it possible to take the energy consumer directly to the energy source. Bitcoin miners are the ultimate customers of previously stranded energy resources, which is why oil producers have started to use natural gas that they otherwise would flare to mine bitcoin.
The location agnosticism of bitcoin mining becomes clear when looking at a map of Texas’ bitcoin mining operations. They are almost all located in the desert in the far west of the state, where they feed on the region’s stranded wind and solar.
