És hogy miért van különbség a fizikai és a commercial áramfolyás között:
One may wonder why physical flows do not follow commercial flows. The difference between physical and commercial flows lies in the laws of physics. Physical electricity flows follow the path of least resistance not commercial flows scheduled destinations. Power plants generate electricity according to the amount of electricity that has been commercially agreed. Grid operators have to transport this electricity to the load centers. If the electricity cannot flow through because of grid bottlenecks, most of it will take the path of least resistance. This, generally, means through the power grids of the neighboring countries
