You can sort, filter, and shop by pricing at YOUR specific usage level, which lets you shop and compare electricity plans based on the rates you’ll actually experience on your bill, inclusive of hidden fees and taxes. This ensures you’re not misled by the cheaper rates often advertised by electric providers…those “teaser rates” associated with higher usage levels that many households never enjoy because their usage level never reaches that pricing tier.
It all starts with the power generators – the companies who produce electricity to sell on the wholesale market. The electricity providers purchase the rights to large volumes of this electricity from the generators on the wholesale market and then turn around and sell it to their retail customers. The electricity providers market the sale of electricity to the public through various offerings of electricity plans that include everything from classic fixed-rate electricity, to 100% green electricity, to bundled products that have incentives such as a Nest Learning Thermostat™ or Visa gift cards.
