Generally, the generation of electricity is unrelated to anything on your bill. Power plant companies generate electricity and sell it to utilities as well as retail electricity providers in deregulated areas. The electricity is then resold to you, the customer. Transmission and distribution is taken care of and charged to you by your utility, regardless of what company supplies the electricity. These charges are separate from the supply portion of your bill.
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”.
Customers can find deals in competitive electricity markets if they take the time and effort to look at web sites such as powertochoose.org, the official comparison shopping site of the Public Utility Commission. The study cited a PUC survey of retail electricity offerings in Houston that showed nine deals in March that were lower than the regulated price of electricity in San Antonio.
