The supply of electrical power for industrial establishments from central stations

We have heard an account of electric power plants planned for each mill to have its own plant. Now, even if the 2000 h.p. plant is of a size greater than the majority of electric central stations, nevertheless the question at once arises why should we not have a central station larger than most of those of to-day and then let the very large station supply the comparatively small plants with all the possible advantages due to size and combination. This is the question on which I shall dwell.
