Ironically, technology can make the utilities’ problem worse, not better—at least in the short term. In the past, grids were developed because it was cheaper to generate large quantities of power and distribute it over wide distances, rather then generate smaller quantities closer to the place of use. It is for this reason that electricity is seen as a business that benefits from “economies of scale”.
The two most common distinctions between customer classes are load size and usage profile. In many cases, time-of-use (TOU) and load factor are more significant factors than load size. Contribution to peak-load is an extremely important factor in determining customer rate class. Consumer loads may be characterized as peak, off-peak, baseload, and seasonal. Utilities rate each load differently, because each has different implications for a power system.
2.     Fraud:  Too many people have been victimized by glib sales reps with promises of cheap electricity flowing in an unending stream only to discover that, as is so often true, “it ain’t necessarily so”.  They’ve been locked into unwanted term contracts or there’s a catch – some utilities will give you the great rate only if you meet a usage minimum; basically, the “rate” is, in actuality, a “bulk purchase” discounted fee – or they paid a deposit never to hear from the rep again.
You can organize and shop by pricing at YOUR individual usage level, which allows you to shop and compare energy plans based on the rates you’ll actually see appear on your bill, inclusive of taxes and hidden fees. You won’t be misled by the “teaser rates” tied with higher usage levels that many homes never experience, as their usage level never reaches that pricing tier.
