Not so much setting up shop next door as an advantage, but moving miners closer to the pool you mine with would. If that happens to be near chearper hydro power, better. But I don't think that power companies mind being able to make more money. With ASICs and GPUs being the constraint against a competitor, power is a lower concern.
