AmortizedFixedCost 
A typical fixed cost is the purchase of the mining rigs and setup of the operation facility. Let I be the fixed cost per 1.0 energy power. Although I is usually described in fiat term, it can be converted to the equivalent energy amount by the introduction of electricity fee rate (the U as mentioned here). Therefore the equation:
Simplify then:
As usual, initial fixed cost tends to be averaged out as longer as the business running.
