In Pennsylvania, you can choose from the EGSs operating in your area, or stay on with your default provider — your EDC. Currently, less than half of all Pennsylvania’s residential customers have made the switch. If you’re among that number, moving to an EGS could get you cheaper rates, better rewards, and more say in what fuels generate your electricity. Whichever you choose, your electricity will get to you just the same because the EDC is always responsible for delivery.

It was later on in the year in September 1882 that Edison opened the Pearl Street Power Station in New York City and again it was a DC supply. It was for this reason that the generation was close to or on the consumer's premises as Edison had no means of voltage conversion. The voltage chosen for any electrical system is a compromise. For a given amount of power transmitted, increasing the voltage reduces the current and therefore reduces the required wire thickness. Unfortunately it also increases the danger from direct contact and increases the required insulation thickness. Furthermore, some load types were difficult or impossible to make work with higher voltages. The overall effect was that Edison's system required power stations to be within a mile of the consumers. While this could work in city centres, it would be unable to economically supply suburbs with power.[1]

Even though customers in deregulated cities routinely pay more for electricity, there is a bright spot. The gap between the average price paid for electricity between deregulated cities like Houston and regulated cities like San Antonio have dwindled to the narrowest point ever to 8.8 percent. Back in 2006, customers in deregulated cities were paying nearly 47 percent more for electricity than their counterparts in regulated cities.

Since the 1990s, many regions have opened up the generation and distribution of electric power to provide a more competitive electricity market. While such markets can be abusively manipulated with consequent adverse price and reliability impact to consumers, generally competitive production of electrical energy leads to worthwhile improvements in efficiency. However, transmission and distribution are harder problems since returns on investment are not as easy to find.
