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”.

Fixed-rate supply plans offer price-protected supply rates for the length of a term agreement. The price per kilowatt hour (kWh) will remain the same throughout your term, even if the market price fluctuates. A fixed-rate supply plan can range from three months to five years, so it’s important to find the term length that works best for your situation.
Prior to electricity deregulation, power was supplied by regional utility monopolies that could own and operate all three parts of electric service. In response to a growing demand for competition in the industry, spurred by the success of deregulation in the airline and telecommunications industries, Congress passed the National Energy Policy Act in 1992 which created wholesale electric markets that allow for open access of generation.
If you spend most of your leisure time out of the house, none of these plans will do much for your bottom line. But if home is your favorite place to be, you could profit. Based on the estimates of energy companies, most people use about 31% of their total energy on the weekends. If you go through the average 1,000 kWh per month, you'll get about 310 kWh for free. Using data compiled by the EIA, we estimated 30% of average total energy is also used during evenings (including weekend evenings), working out to about 300 free kWh.
But, again, the concept isn’t difficult. Let’s use the city of Joliet as an example. Joliet’s traditional utility for the 60435 area code is Commonwealth Edison. As of late February, its price to compare is 7.195 cents per kilowatt hour (kWh); at this writing, four plans from featured suppliers with lower rates, including one that’s 18% cheaper and uses all green energy.
Switching electricity supplier could shave pounds off your bills. But it’s not always about how much hard cash you could save. You might be fed up with poor customer service, you might want greater visibility of your usage through an app or you might want to choose your supplier based on their green credentials, or whether they supply a smart meter.
